1004 PM EST Tue Feb 8 2022 .SYNOPSIS... Lake snows east of Lake Ontario will bring a few inches of accumulation tonight and again late Thursday afternoon into Thursday night. Otherwise, looking at mainly nuisance rain/snow showers at times with temperatures generally above normal for the rest of the work week. && .NEAR TERM /THROUGH WEDNESDAY/... Sharp mid-upper level trough is crossing region today with H5/H7 temps down to -30c/-16c per RAP analysis. Lake effect snow showers are expected to continue this evening, mainly east of Lake Ontario with larger scale forcing from the trough and longer over-water fetch on westerly flow across Lake Ontario. Inversions rise to 6- 8kft briefly this evening before falling later tonight as warm air advection quickly develops downstream of next upper trough and sfc low diving across the northern Plains to Upper Great Lakes. Still a window of time, through late evening where if flow aligns and persists long enough several inches of lake effect snow could occur across northern Oswego county into southern Jefferson county eastward across the Tug Hill, before backing return flow and warm air advection spell end to the lake effect. Right now appears majority of snow will remain east of Oswego and south of Watertown, but could impact I-81 at times. Otherwise tonight, expect diminishing snow showers elsewhere with skies becoming partly cloudy as the trough quickly shifts east. Temps will fall off this evening western NY to Genesee Valley upper teens to near 20, before becoming steady or slowly rising late tonight. Temps east of Lake Ontario will fall to the middle teens by late tonight. We`ll flip the pattern tomorrow, at least briefly as strong warm air advection ramps up in the morning ahead of the Upper Great Lakes system. Temps will rocket up through the 30s and reach into the lower to maybe middle 40s by early afternoon before temps fall back late in the afternoon as leading cold front returns to region from the west. Mid to high clouds ahead of the system, then thickening clouds in the afternoon. Weak lift ahead of the front may result in a few showers, mainly in form of rain, mid to late afternoon. Then colder air working in late behind the cold front could lead to rain/snow mix. Light intensity to any precip through the day. Soundings indicate LLJ that accompanies the warm front may begin to mix down in the afternoon as cooler air arrives, leading to southwest winds gusting 20-30 mph near Lake Erie and over western Niagara Frontier in the afternoon. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... A pair shortwaves and fronts will bring progressively colder air across the region with chances for snow showers through Thursday...along with some enhanced snow shower activity ENE of the lakes. Thursday evening...behind the final front 850 hPa temps drop down to -10C/-12C over the lakes as the trough moves over and through the region. This will likely be enough to support...albeit brief...a period of accumulating lake snows east of Lake Ontario. A 250-260 flow will initially direct lake snows across S. Jefferson and far N. Oswego County. The availability of the longer fetch of lake Ontario and any added upstream connections will lend just enough support to potentially produce several inches (3-5 inches) of snow before lake snows track to the north and then diminish by Friday morning. Off Lake Erie...a similar scenario will unfold but be hampered by the shorter fetch of the lake which will likely limit accumulations. That said...thinking guidance is a bit underdone due to ice coverage represented in the modeling. Have bump up snowfall accumulations across S. Erie and a small portion of Chautauqua County to reflect this issue. Even appears we are only looking at a few inches (1-3 inches). Winds gradually back to the SW then S as we progress through the night. When this occurs...lake snows will push north and then quickly weaken as a mid-level warm front pushes into and through the area. Friday...any remaining lake snows will end early in the morning as warm air advection processes take over. This will leave the area precipitation free ahead for much of the day ahead of the next clipper and cold front. High temps climbing to near 40F. Friday night...clipper and its cold front approach the region with increasing chances for snow showers overnight. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Arctic cold front plows across western and northcentral NY Saturday morning. A mix of rain and snow showers with the front initially will quickly transition to all snow from northwest to southeast by early afternoon, then taper off to scattered snow showers behind the boundary during the second half of the day. The other signature of this boundary will be the much colder air that filters in across the area in the wake of the front for the second half of Saturday right through the first part of the new work week, with at least the chances for some limited lake effect snow downwind of the Lakes Saturday night and Sunday. Next upper level trough and associated moisture starved cold front will bring a reinforcing shot of cold air and possibly some scattered snow showers as it crosses the area Sunday night. Next weak clipper type system moves through the area to start the new work week with some light snow showers possible Monday and Monday night, before high pressure builds in Tuesday with increasingly drier weather expected. Otherwise, highest temperatures during this entire period will be at the start Saturday morning. Temps then fall through the day Saturday, with readings taking a dive back to well below average right through the end of the period. && .AVIATION /03Z WEDNESDAY THROUGH SUNDAY/... Snow showers will remain confined to areas east of Lake Ontario overnight. A brief heavier snow shower could drop vsby to MVFR at KART between 04z and 08z. Otherwise VFR conditions overnight. Outlook... Wednesday...Mainly VFR. Thursday...MVFR to VFR. Chance of snow showers. Friday through Sunday...MVFR. Chance of snow showers. && .MARINE... Winds will lower during the overnight into Wednesday as high pressure moving off to the east backs winds southerly. A warm front will cross the lake later Wednesday, shifting flow to the southwest. Low pressure over the northern Great Lakes will slowly move east and the enhanced pressure gradient will bring a period of small craft headlines by Thursday. && .BUF WATCHES/WARNINGS/ADVISORIES...

936 PM EST Tue Feb 8 2022 .SYNOPSIS... High pressure begins to shift eastward but keeps conditions dry through Wednesday night. Several waves of upper level energy will keep clouds and chances for precipitation in the forecast the next several days. A stronger system moves in late on Friday and pushes out on Saturday, setting up the Ohio Valley for a cool and mostly dry weekend. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... There is a pretty wide variation in temperatures across the region this evening, with mid 20s in the cool spots in central Ohio (25 at VTA) and much warmer conditions in northern Kentucky (42 at KY Mesonet HHTS). With SSW flow expected to increase over the next couple hours, would expect little (if any) further drops in temperatures tonight, with some gradual rises expected after 06Z. With no model really picking up the current gradient all that well, the hourly temperature traces were difficult to project precisely for the next 4-8 hours, but in general min temps should be close to the current values being observed as of 9PM. Based on 00Z model data, there remains some subtle evidence of a weak front aloft (850mb/700mb) just ahead of the mid-level trough axis, roughly coincident with where the HRRR is suggesting a narrow band of light rain/snow may develop tomorrow morning. Will keep the low-end PoPs for this feature, though would expect most places will be unlikely to receive anything measurable. Previous discussion > A broad region of high pressure remains stretched across the Ohio Valley down through the lower Appalachians and into the Gulf. This high pressure system gradually shifts eastward throughout the day. Return flow on the back side of the high will begin to advect warmer air in from the Gulf. Even though skies do become mostly clear overnight, sustained southerly winds of 5-10 mph should help moderate temperatures and keep lows to near or just below freezing across our CWA. During this period, influence of the high pressure will keep conditions dry. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... An H5 trough and its associated PVA traverses the ILN fa Wednesday morning, which could offer some isolated to scattered pcpn as a rain-snow mix during the morning. Several hi-res models do show this potential weak line of pcpn traversing our CWA in the morning, so decided to include slight chance to low end chance for PoPs during this timeframe. The afternoon should offer a relatively dry period for our counties before the primary cold front moves in later during the evening. Skies will generally remain mostly cloudy to overcast throughout the day with the low levels continuing to saturate. Majority of our counties south of I-70 should observe highs above 40, with counties near/south of the OH River potentially observing temperatures near 50 with the enhanced WAA during the day. By the evening, a surface cold front will begin to move in from the west, increasing chances for pcpn. While majority of models (as well as the HREF) do show a good signal for pcpn, the overall QPF remains very light, so PoPs generally remain in the chance category for now due to lower coverage. Light snow accumulations will be possible in our northern counties along and N of I-70, but snow accumulation should be pretty limited. && .LONG TERM /THURSDAY THROUGH TUESDAY/... Positively-tilted mid-level trough will pass across the area at the beginning the period which, combined with low level cold air advection, will keep a good amount of cloud cover over the region until late in the day. Surface high pressure will quickly move east Thursday evening with a fairly strong pressure gradient developing ahead of the next approaching system. So expect temperatures to drop quickly during the evening but then steady out and even start to rise before daybreak Friday. Strong mid-level short wave will pass across the Great Lakes on Friday into Friday night. This will push a cold front across the area. Precipitation will occur with this system, mainly as rain. But if precipitation starts early enough on Friday or lingers late enough into Friday night, there could be some snow. There is also some potential for light precipitation to persist into Saturday morning. There will be a large temperature gradient across the forecast area on Friday with highs ranging from the lower 40s in the north to the mid 50s in the south. After the front moves through, there will be a return to below normal temperatures area wide. Long wave trough will remain across eastern North America into early next week. A stronger impulse will drop into this trough on Monday, but with some uncertainty with moisture availability, kept PoPs low. Once this system moves through, ridging will ensue with the beginning of some moderation in temperatures. && .AVIATION /03Z WEDNESDAY THROUGH SUNDAY/... VFR conditions are expected through most of the TAF period. LLWS will be likely to occur overnight, along with surface winds out of the south / south-southwest to around 10-12 knots. This will persist through early Wednesday morning. There may be some brief showers (perhaps a very light rain/snow mix) moving through some of the airports in the 13Z-16Z time period, but no significant impacts are expected. Some precipitation chances may also occur very late in the TAF period, but chances are too low to include in any of the TAFs except KDAY as of now. OUTLOOK...MVFR ceilings are possible at times through Thursday, and MVFR ceilings are possible again on Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.

848 PM CST Tue Feb 8 2022 .SYNOPSIS... Issued at 239 PM CST Tue Feb 8 2022 Temperatures are expected to warm into the upper 30s to lower 40s Wednesday which will continue to slowly eat away at the deep snow pack across much of central Illinois. A few widely scattered showers are possible Wednesday afternoon and evening, but most of the day will remain dry. The next chance for more widespread rain and snow arrives Thursday night and continues into Friday. && .UPDATE... Issued at 848 PM CST Tue Feb 8 2022 A weak cold front is moving into the Illinois River Valley this evening, and will reach Indiana by sunrise. The front will produce a shift to westerly winds and be associated with mid-level cloud cover, but will have a fairly subtle cooling behind it, and very little chance of precipitation. A couple high-res models depict a weak precipitation band as it enters Indiana, so will leave a chance of flurries in forecast from I-57 eastward after midnight. Otherwise, lows look to be upper 20s most areas, upper 30s south of I-72. Afternoon forecast package needs no significant updates. && .SHORT TERM...(This evening through Wednesday) ISSUED AT 239 PM CST Tue Feb 8 2022 Through Wednesday, an upper trough will slowly shift east across the Great Lakes while, at the surface, low pressure currently centered over Manitoba will shift to eastern Ontario/James Bay. A weak trailing front will pass across central Illinois tonight followed by another cold front Wednesday afternoon. Do not anticipate any significant weather from tonight`s front other than a modest wind shift to westerly and increasing mid and high clouds. Couldn`t completely rule out some isolated sprinkles/flurries, but most of central Illinois will remain dry overnight. Winds will back to the southwest again Wednesday morning ahead of the next front which will contribute to another mild day considering the deep snow pack still in place across the area. With this second wave, expect steepening low and mid level lapse rates with the top of mixed layer positioned within the snow growth zone. This could allow for isolated to widely scattered showers to develop during the late afternoon and evening as an H5 vort max pivots across portions of central and northern Illinois. While global guidance generally favors the northern half of the state for any precip, the RAP and HRRR indicate the potential for showers across the entire CWA so have added slight chance PoPs to account for this possibility. Boundary layer temperatures are warm enough to support a mix of rain and snow Wednesday afternoon and evening, though dynamic cooling from any heavier showers should support a transition over to snow. If any snow showers develop, a quick dusting is possible, but overall coverage is expected to remain low to mitigate the threat of widespread impacts. .LONG TERM...(Wednesday night through Tuesday) ISSUED AT 239 PM CST Tue Feb 8 2022 Northwest flow aloft will be the general rule Thursday through at least the weekend with a number of shortwave digging across portions of the Great Lakes and Midwest. Temperatures return to below normal Thursday as H85 thermal trough is centered over the Midwest. A strong wave is progged to dig across the Canadian Prairies into the northern Great Plains Thursday into Friday. In response, shortwave ridging and mid level warm air advection will overspread portions of the Midwest in advance of this trough which will help push temperatures back into the 40s at least briefly on Friday followed by the next chance for precip starting Thursday night. Precip may begin as snow before changing over to rain as the column warms. A strong cold front will push across central Illinois later Friday with precip chances diminishing in its wake. Over the weekend, a strong 1040mb high will spread southeast from the northern Great Plains and Upper Midwest. The ridge axis will move across Central Illinois Sunday morning bringing back the next chance for single digits temps to the area. A reinforcing cold front will move across the region Sunday night prolonging the cold temps into Monday of next week. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 542 PM CST Tue Feb 8 2022 VFR conditions expected through tonight as a cold front brings additional mid and high level cloud cover. An upper level disturbance arriving Wednesday afternoon will bring more moisture and cloud cover, with central IL having predominantly MVFR cigs or lower VFR and possibly a few showers. Winds S 09-13 kts this evening, shifting to W and gusty after the cold front moves trough around 03Z-06Z. W winds continuing through the forecast period, and remaining 08-12 kts with higher gusts. && .ILX WATCHES/WARNINGS/ADVISORIES...

642 PM CST Tue Feb 8 2022 .SHORT TERM... (Through Late Wednesday Night) Issued at 217 PM CST Tue Feb 8 2022 An upper-level shortwave trough traversing the Midwest will force a cold front southeastward through the CWA this evening. Given that low and mid levels will be quite dry (PW <0.5") and ascent is not anticipated to be vigorous, passage of this front will devoid of precip and only mark the onset of weak CAA as low-level flow veers to the west-northwest in its wake. Another upper-level shortwave trough will arrive in Wednesday with another cold front pressing southeastward through the region. The combination of cyclonic flow through a deep vertical layer, steepening low-level lapse rates (from CAA maximized around 700 hPa), and marginal low-level moisture could also be sufficient to yield isolated rain showers across east- central and south-central IL with weak low-level convergence along the cold front during the late afternoon/evening. The 18z HRRR is the most aggressive with this scenario, even generating 100 to 200 J/kg of MUCAPE, but its solution is likely contaminated by erroneously high surface dewpoints. A few snow flakes could mix with the rain as the boundary layer cools during the evening. Behind the first front, temps at 850-hPa will cool 7 to 10 C between today and Wednesday, but with surface winds and low-level flow predominantly westerly ahead of the second cold front high temps will again be above average and only up to 10 F cooler (in the low-40s to mid-50s F). Reinforcement of CAA will occur again behind this second front. Pfahler .LONG TERM... (Thursday through Next Tuesday) Issued at 217 PM CST Tue Feb 8 2022 Prevailing weak CAA will continue into Thursday with high temps approximately average for early/mid-February. At upper levels, time- mean northwesterly, broadly cyclonic flow will remain established over the Midwest through the remainder of the week and into early next week. This flow will be navigated by a continued parade of upper-level shortwave troughs, partially consisting of a weak shortwave trough early Thursday and a sharper, more robust shortwave trough propagating across the region late Thursday night/Friday. This second shortwave trough will send a stronger cold front through the CWA, relative to its predecessors. There should be greater moisture, although still somewhat limited, available to interact with more vigorous ascent stemming from pre-frontal WAA and low- level convergence along the front. Therefore, light precip will be possible ahead and along the cold front late Thursday night into Friday. Some wintry precip cannot be ruled out briefly initially Thursday night, but strong WAA should quickly raise temps above freezing, favoring rain thereafter. Friday could be another warm day across the CWA with strong low-level southwesterly flow, deeper mixing near the front, and a majority of the snowpack likely eroded by that point from previous days of melting. The exact magnitude of warmth will hinge upon the timing of frontal passage with later a later passage favoring warmer temps than currently forecast. Behind the cold front, CAA will facilitate the arrival of a much colder airmass Friday night with 850-hPa temps falling to around -15 to -18 C (-1 std dev below average). This airmass will promote below average temps through Saturday. However, yet another upper-level shortwave trough will traverse the Midwest around Sunday, providing a brief moderation and then cooling of temps into Monday. Global model guidance are indicating that a large-scale upper-level flow pattern change will take place across the CONUS shortly following this shortwave trough`s departure, breaking the northwesterly flow regime. Pfahler && .AVIATION... (For the 00z TAFs through 00z Wednesday Evening) Issued at 639 PM CST Tue Feb 8 2022 VFR flight conditions are expected to prevail through Wednesday. A weak cold front will move through the region on Wednesday. Some lower VFR clouds between 4000-8000 feet will likely accompany the front, and there may be a few sprinkles along and east of the Mississippi River, but no major impacts are expected other than a wind shift to the west-northwest.

Issued by National Weather Service Springfield MO 521 PM CST Tue Feb 8 2022 .SHORT TERM...(Tonight through Thursday) Issued at 233 PM CST Tue Feb 8 2022 A mild day is occurring across the quad state region this afternoon as temperatures have warmed into the upper 40s to mid 50s thanks to southwesterly winds and sunny skies. Some cloud cover moves into the area overnight into tomorrow as a cold front passes west to east across the region on Wednesday afternoon into evening. Due to the later passage of the front, high temperatures on Wednesday will again be mild and very similar to today. Weather should generally remain dry given a relative lack of moisture with the frontal passage, but the RAP and HRRR short term models do suggest some low-end isolated shower chances across southern Illinois and Indiana. Have included slight chance PoPs Wednesday evening to account for this. Dry conditions and slightly cooler temperatures in the 40s to low 50s (coldest over the northern CWA) are in store for Thursday under mostly clear skies a weak surface high pressure moves over the quad state region. .LONG TERM...(Friday through Tuesday) Issued at 233 PM CST Tue Feb 8 2022 Overview: Overall, this portion of the forecast looks predominately dry, though some low end precipitation chances will be possible again on Friday and Saturday despite some model variance. The upper-level pattern late this week into early next week will be mainly defined by west to northwesterly flow across the region given am upper-level ridge over the eastern Pacific and western CONUS and a general troughing pattern over the eastern half of the CONUS. Friday-Tuesday: Inside this northwesterly upper-level pattern, a couple shortwave trough/surface cold front pairs are expected across the region: the first on Friday evening into Saturday and another on Sunday night into Monday. The overall moisture return with these systems are lacking, but the GEFS does show a weak remnant of Pacific moisture present with the Friday-Saturday system. This could be just enough moisture to produce some light, measurable precipitation for the area, but chances are low at the moment. If we do see precipitation with the Friday-Saturday system, it looks to be mainly in the form of rain, but could briefly mix with snow if any precipitation falls Friday night. The Sunday night clipper system looks to be even more moisture starved, so this is currently reflected in a dry forecast for Sunday night-Monday. A colder airmass moves in behind the late Friday cold front, dropping high temperatures back into the 30s for Saturday and Sunday. Model consensus is in fairly good agreement on a shortwave ridge moving over the central CONUS early next week, which should lead to temperatures gradually warming back to near 50 degrees by Tuesday with the early portion of the week remaining dry. Mid-late next week: Larger upper-level troughing digs through the Rockies into the central CONUS, with an associated surface low developing with it. Ensemble guidance hints at a better fetch of western Gulf moisture being brought northward with this system, with a potentially wetter pattern in store for this timeframe further backed by a wet signal in the CIPS extended analog guidance. && .AVIATION... Issued at 514 PM CST Tue Feb 8 2022 Initially clear skies will continue into tonight before some mid level cloud cover slides over the region. Despite clouds moving over the area, VFR flight conditions will prevail. In advance of an approaching dry cold front, low level winds shear will impact the areas TAF sites into the early morning before diminishing early in the morning. && .PAH WATCHES/WARNINGS/ADVISORIES...

756 PM PST Tue Feb 8 2022 .UPDATE...A few light showers developed across the Lower Columbia Basin and the northern Blue Mountains this evening but trace amounts were observed. Any shortwave on satellite is not discernible but WSR-88D did show returns around 20-40dBZ. The shortwave also caused winds to increase to around 15-20 mph in the Kittitas Valley and the eastern Columbia River Gorge where a cross-Cascade gradient is present, albeit weak. The HRRR did a great job initially with the composite reflectivity, as it showed the showers dissipating at this time. The precipitation has encountered subsidence with the stable high pressure and has mostly ended. Forecast was updated to add sprinkles earlier this evening in the Columbia Basin and Blue Mtn Foothills as well as bump up winds slightly in the Eastern Gorge and Kittitas Valley. Wister/85 && .PREV DISCUSSION... /issued 217 PM PST Tue Feb 8 2022/ SHORT TERM...Today through Thursday...An upper-level ridge is currently parked off the coast of the Pacific Northwest and is expected to persist through the period. As far as sensible weather, a weak shortwave combined with some modest Pacific moisture wrapping around the top of the ridge will lead to a slight chance of light rain and light high-elevation snow for the Washington Cascades, northern Blue Mountains, and Wallowas/adjacent high terrain in Wallowa County tonight through Wednesday morning. This increased moisture and perhaps a bit more cloud cover may also serve to moderate tonight and Thursday morning`s lows compared to what was observed this morning. Additionally, periodic breezy conditions through the Kittitas Valley and adjacent high terrain may occur through Thursday afternoon. Perhaps the most notable point of discussion is afternoon high temperatures each day. Highs will range from the low 50s to low 60s this afternoon for much of the forecast area, though some higher valleys in northeast Oregon have yet to mix out and are stuck in the 20s and 30s. 850 mb temperatures are forecast to rise through the period, so expecting afternoon highs of mid 60s to 70 possible Thursday across central Oregon. More uncertainty exists for the Foothills of the Blue Mountains, the Columbia Basin, and the aforementioned high valleys due to the potential for strong subsidence inversions to set up. Should the inversions lead to the development of stratus decks, fog, or just fail to fully mix out for the aforementioned areas, afternoon highs could be significantly cooler than forecast. The NAM is currently advertising this situation for the Washington side of the Columbia Basin and adjacent valleys Wednesday and Thursday, though other guidance is not as aggressive with the stratus and thus have warmer afternoon highs. Have opted to keep afternoon highs a few degrees warmer, nudged towards the 50th percentile for the NBM as this is generally a few degrees warmer than the deterministic NBM. Plunkett/86 LONG TERM...Friday through Tuesday...A ridge of high pressure centered along the coast will move inland late Friday and Saturday continuing the warm and dry trend into the weekend. The ridge will then flatten on Sunday as an approaching upper level trough approaches from the Gulf of Alaska. This trough will push a cold front through the region late Sunday night and Monday followed by the trough passage Monday night and Tuesday. The front push a band of precipitation across the forecast area on Monday mainly impacting the Cascades and eastern mountains with some rain changing to snow as snow levels lower. Behind the front there will be increasing westerly winds which will linger into Tuesday. Precipitation will also taper off to showers over the mountains on Tuesday. AVIATION...00Z TAFS...Mid and high level clouds coming over the ridge will provide BKN-OVC AOA 10-15K through the period with some FEW-SCT 070-12K. This will allow VFR conditions to prevail.
