Area Forecast Discussion
National Weather Service Cleveland OH
646 PM EST Tue Dec 20 2022 .SYNOPSIS... A cold front moves into the area tonight, lingering across the area Wednesday and Wednesday night before lifting back north as a warm front on Thursday. A rapidly deepening low pressure system is expected to lift northeast out of the Oklahoma Panhandle Thursday into the Great Lakes region by Friday, bringing a strong, arctic front across the region early Friday morning. The low pressure system is expected to continue to deepen while moving north away from the area with a trough extending southward into the Great Lakes region Saturday and Sunday. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... A weakening cold front moves southeast into the forecast area tonight, settling south of Lake Erie Wednesday and Wednesday night. Scattered cloud cover expected through Wednesday night, with some sunshine likely appearing during the day on Wednesday. Highs remain in the mid to upper 30s, though area south of the front may get into the low 40s. The front sags just far enough south for temperatures to drop below freezing Wednesday night into early Thursday morning before the front lifts back north as a warm front. Precipitation begins to develop over the Ohio Valley Thursday morning, lifting north into the local forecast area during the daytime hours. Initial wave of precipitation Thursday morning may fall as mixed precipitation (freezing rain and snow) before transitioning to all rain. Very low impacts expected with the initial, brief wintry mix due to low coverage and brief nature. Temperatures rise back into the low 40s areawide by Thursday afternoon/evening. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... There continues to be high confidence in a multi-hazard storm system that will impact the entire forecast area from late Thursday night through Saturday night with the main hazards, in order of severity: winds, cold, and snow. Winter storm watches will be needed at some point (possibly in the overnight package), but confidence remains too low at this point to nail-down specific areas, especially given the recent northward trend of the wrap-around snow and the possible need for additional wind and/or cold headlines (either advisories or warnings). Meteorological Discussion and Forecast Challenges... There continues to be consensus on a low pressure system developing over the southern plains on Thursday morning and being picked up by a strong upper level trough that will become negatively tilted with time. This low pressure system will deepen to near 970 mb as it reaches just north of Lake Ontario. Meanwhile, a roughly 1060 mb Arctic high will enter down the spine of the Rockies and send in a shot of extremely cold air across the region. The combination of the deepening low and encroaching Arctic high will allow for a major winter storm and strong cold front to impact the Great Lakes region. As mentioned above, the latest guidance still suggests a potential dry-slot developing immediately behind the cold front late Friday morning and early afternoon. In addition, the wrap-around moisture associated with the TROWAL Friday evening and overnight has also trended slightly northwards. There still will be significant precipitation impacts with the cold front Friday morning. Precipitation should almost immediately switch over from rain to snow along and behind the front, in addition to the possibility of a flash freeze. Brief whiteouts are not out of the question with any snow showers associated with the cold front. Summary of Hazards: Significant Winds... The wind potential with this storm system remains the most significant hazard for the forecast area. With the low pressure system deepening near the area on Friday and lingering to the north on Saturday, there will be a prolonged period of strong southwest winds across the region. The most concerning item remains strong winds at the 850 and 925 mb layers respectively. Current guidance is suggesting 925 mb winds on the order of 45 to 55 knots with 850 mb winds of 65 to perhaps 75 knots. Mixing heights Friday afternoon and evening are forecast to reach somewhere between the 925 and 850 mb layer, and thus the potential for intense and damaging winds to reach the surface. In this forecast iteration, we have slightly raised wind gusts, with 45 to 55 mph winds expected across the entire forecast area. Wind gusts of 60 mph and perhaps higher will be possible closer to the lakeshore, especially Friday evening. Power outages are certainly possible and thus we suggest taking the necessary time and steps to prepare in advance. Extreme Cold... Forecast confidence remains the greatest of all hazards for extreme cold for Friday through Sunday morning. With the frontal passage late Thursday night/Friday morning, temperatures will start around 40 degrees around Midnight and then fall to the single digits by early Friday afternoon behind the front. This quick drop in temperatures will pose a flash freeze threat as rain will quickly change to snow and wet surfaces will freeze up due to the cold and wind entering the region. This air mass will persist through the short term period and through the weekend. It is possible that some areas will not rise above the single digit mark over a 48 hour period which could cause major infrastructure issues. In addition, gusty winds across the region will result in dangerously-cold wind chills; as low as -20 to perhaps -25 degrees F in some spots Friday night. Sub-zero wind chills are expected to persist through the weekend. Snowfall...Confidence is slightly increasing on the snowfall magnitude expected for the event, though it remains relatively low compared to the cold and wind threats. As of now, our forecast calls for a widespread 3 to 5 inches of snow early Friday morning into Friday evening, with the precipitation along the front being the main driver for accumulations. It is possible that wrap-around moisture from the TROWAL may enhance some of these totals late Friday, though recent guidance suggests a slight northward trend for this potential. Additional lake enhancement and/or lake-effect snow is possible across the snowbelt Friday night into Saturday, though there remains disagreement on the magnitude and the placement of any lake-effect bands that develop. At this point, the most likely scenario is that southwesterly flow aloft would favor the highest accumulations across western NY. Blowing and drifting snow is also a concern for much of the area, given the strong winds and anticipated "dry", high-ratio snow. Please continue to follow the forecast over the next several days as this storm system evolves and final headline decisions are made. Prepare for a significant system with a range of wind, cold, and snow impacts and anticipate disruptions for holiday travel plans towards the end of the week. We want to ensure that all folks have a safe Christmas and holiday season, even with this approaching system. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Below-average temperatures and dangerously-cold wind chills will persist through the first half of the long-term period with the arctic air mass overhead. High temperatures on Saturday will struggle to get out of the single digits with wind chills of -15 to - 20 degrees F likely, even during daylight hours. We`ll also need to monitor any lake-effect snow, though as mentioned above, the most plausible scenario is for any lake-effect band that develops to favor western NY. Temperatures will try to improve on Sunday with more teens appearing in the forecast, though wind chills will remain sub-zero. By early next week, temperatures will finally rebound into the 20s area-wide, though will remain below-average. We`ll need to monitor another system on Tuesday, albeit on the weaker side, for the potential of light snow accumulations. && .AVIATION /00Z Wednesday THROUGH Sunday/... VFR across the board this evening. A weakening cold front moves in from the northwest tonight, and currently has an area of MVFR stratus in tow upstream over the Great Lakes. Based on upstream trends, GLAMP guidance and HRRR forecast soundings did elect to bring prevailing MVFR cigs in to most sites starting late tonight or early Wednesday. These will gradually scatter out/dissipate Wednesday afternoon. Did not bring CAK and YNG to MVFR yet due to the expectation that drier air will eventually stop the progression of the stratus farther south/east. Forecast soundings suggest some sites, such as FDY and especially MFD, may flirt with IFR cigs Friday morning, but confidence is low. Will analyze upstream trends next cycle for this potential, as there currently aren`t any IFR cigs upstream. Winds remain fairly light and variable through the TAF period. Outlook...A low pressure system moving into the Great Lakes region will bring non-VFR with rain on Thursday, changing over to snow on Friday and Friday night. Lake effect snow may develop on Saturday and Sunday. Very strong winds with gusts exceeding 40 knots are expected Friday through Saturday. && .MARINE... A storm watch has been issued for all of Lake Erie starting at 12Z Friday with a current end time of 15Z Saturday for the western basin, and 0Z Sunday for the rest of the lake. A very strong cold front will move west to east across the lake Friday morning, ushering in strong, southwesterly winds of 40 to 50 knots with higher gusts of 60 to perhaps 65 knots possible. These strong, southwesterly winds will persist through Friday into Saturday. Low water is also possible across the western basin of the lake, with current forecasts suggesting water levels to fall as low as 3 to 4 feet below the low water datum. Finally, in addition to the strong winds, an anomalously-cold air mass will descend south across the Great Lakes. Heavy freezing spray will be likely across much of the lake beginning Friday afternoon with the threat persisting through Saturday. A Heavy Freezing Spray Watch may be needed going forward. Conditions will begin to improve from west to east across the lake on Sunday, though we may need additional headlines (Small Craft) with continued west to southwesterly winds of 15 to 25 knots. && .CLE WATCHES/WARNINGS/ADVISORIES...

National Weather Service Cheyenne WY
732 PM MST Tue Dec 20 2022 .UPDATE... Issued at 723 PM MST Tue Dec 20 2022 Made a quick update before the start of the nighttime/early morning forecast package later tonight. Forecast appears on track with high winds getting going across the Arlington/Elk Mountain area late this evening with a few gusts of 55 MPH observed so far. These winds will continue to increase and spread eastward into the high plains over the next 12 hours ahead of the arctic front plunging south out of Canada. This front is just starting it`s trip south with temperatures in northern Montana lowering between -20 to -25 over the last hour. The front is still expected to enter the forecast area (Converse and Niobrara Counties) between 7 to 9 am Wednesday morning and then accelerate southward towards the Colorado border through noon. UPDATE Issued at 300 PM MST Tue Dec 20 2022 Forecast remains on track for strong winds across portions of southeast Wyoming returning tonight, strong frontal passage during the day Wednesday with snowfall and rapid drop in temperatures, and the frigid arctic air leading to extremely dangerous wind chills Wednesday night through Friday morning. This discussion provides a quick update on these hazards with the latest forecast package. Decide to upgrade the High Wind Watches to Warnings beginning this evening for the Central and South Laramie Range. Forecast models persisted with the strong upper level flow and downward omega across the Laramie Range and adjacent foothills. Additionally, bumped up the start time for the remaining areas in Carbon/Albany/Converse County to 5 AM MST with 700mb flow increasing a little sooner with a slightly quicker arrival of the upper level trough (will get to more about this in a moment). NBM v4.1 probability of exceeding 48 kt gusts shows over 60% for most of the warned area while in-house guidance continues to show support these winds ahead of the frontal passage. Looking at most hi-res guidance, appears that the frontal timing as sped up by a few hours with initial entry into northern portions of the CWA by 8 AM MST. Timing the rest out, looks to reach the North Platte River valley (Scottsbluff/Torrington) right around 11 AM MST and Cheyenne around 2 PM MST while crossing the Colorado border to the east a little earlier. Hi-res guidance continues to hint at nearly 30F degree temperature drops behind the front in the first hour or two after its passage. Decide to blend forecast grids more with hi-res guidance to reflect a sharper temperature gradient and earlier arrival. This timing will be a little more delayed west of the Laramie Range, however forecast soundings indicate snow squall potential with around 100 J/kg of low level instability present. Winter Weather Advisories were added for most locations Wednesday across Carbon and Albany counties in addition to the I-25 corridor from Cheyenne to Wheatland with the potential for a quick 1-3 inches of snowfall in addition to the flash freeze behind the front making for slick road conditions in the afternoon and evening hours. These locations had more confidence in more widespread effects, but will need to monitor radar/satellite trends tomorrow within the advisory area and farther east into the Nebraska Panhandle as Snow Squall Warnings may be needed for the highest intensity snowbands. These advisories run through 5 PM Wednesday as the frontal forcing will quick move through the CWA, however will need to monitor for potential lingering effects with possible upslope along the South Laramie Range. Areas around Cheyenne could see light snowfall continuing into Wednesday evening and latest SREF guidance even suggests higher snowfall totals could be possible. Temperatures will continue to plunge behind the front through Thursday morning. Latest forecast has Cheyenne dropping ~60F degrees between early afternoon Wednesday to Thursday morning. Latest forecast trends looked to slide the trough a little quicker to the east displacing the core of coldest 700mb temps from our areas. So did slightly nudge temperatures upward, but they still remain frigid. Thursday morning lows will still be widespread 20 to 35 degrees below zero with wind chills feeling 40 to 65 degrees below zero which will be extremely dangerous and life threatening! Wind Chill Warnings remain in effect at this time continuing through the day Thursday, which won`t see high temperatures above zero, and into Friday morning. As for the long term, still looks to warm up nicely headed into the weekend. While temperatures will drop hard late in the week, we could be looking at a 50-60F degree temperature swing from Friday morning to Sunday afternoon. Additionally, decide to keep the uptick in the winds by blending in NBM 90th percentile with strong flow aloft returning with tightening gradients and a quick passing shortwave to the northeast. && .SHORT TERM...(Today through Thursday) Issued at 426 AM MST Tue Dec 20 2022 ...EXTREMELY DANGEROUS AND POTENTIALLY LIFE THREATENING COLD WAVE SET TO IMPACT THE REGION...FARM AND RANCH INTERESTS SHOULD MAKE FINAL PREPARATIONS NOW... ...HIGH WINDS AND PERIODS OF SNOW AND BLOWING SNOW ALSO EXPECTED WITH THE ARCTIC FRONT... An active 24 to 48 hours ahead for southeast Wyoming & the western Nebraska Panhandle w/ multiple significant, high-impact hazards to impact the CWA. Strong winds impacting the southeast Wyoming wind- corridors early this morning will become more widespread tonight & Wednesday. Mountain snow is likely to develop across the Snowy and Sierra Madre ranges later this afternoon, likely becoming heavy by mid-day Wednesday. Widespread light to moderate snowfall is likely along the cold front on Wednesday morning and afternoon, with some locally intense banding & snow squalls likely. Extremely dangerous and potentially life-threatening wind chills are likely to rapidly develop behind the cold front with serious impacts possible to the livestock and agricultural communities, as well as more vulnerable human populations, especially Wednesday night through early Friday morning. Wind gusts of 65 to 70 MPH have been common near Arlington and Elk Mountain early this morning. This is likely the result of enhanced H85 CAG-CPR gradients near 70 meters between lee troughing along & east of the Laramie Range & the surface high over western Colorado currently in place. These gradients may diminish somewhat over the next few hours, but steep low-level lapse rates combined w/ around 45 knots of 700-800 millibar flow should be sufficient to keep the gusts elevated above 45-50 MPH through the day. After 00z, CAG-CPR gradients will rapidly increase yet again as the lee trough should intensify in response to difluent flow in advance of a significant mid-level short wave diving into the Intermountain West. Local in- house probabilistic guidance suggests a strong signal for gusts 60 MPH or stronger after 03z this evening, leading to the decision to extend the current warning through 00z Thursday. Would expect this to be cancelled a few hours early once the front passes around mid day Wednesday. A similar scenario can be expected for the southern Laramie Range including the I-80 Summit, with H75 flow near 60 kts requiring High Wind Warning issuance through 11 AM MST today. Will see a decent decrease in speeds this afternoon, but a west to east oriented MSLP gradient on the order of 4-6 millibars will begin to take shape between Laramie & Cheyenne after 03z this evening along with a sharp omega couplet / mountain wave signal and 55 to 65 kts of H7-H8 flow. This should be more than sufficient for gusts to 65 to 75 MPH overnight through mid-day Wednesday prior to the passage of the arctic front. These winds could even spill east into Platte County. A High Wind Watch has been issued for the Southern Laramie Range and adjacent Foothills, as well as much of Platte County, to include Wheatland, Glendo, and the Coleman WYDOT sensor. Extreme MSLP gradients are expected with the passage of the arctic front on Wednesday. Significant low-level mixing will likely occur ahead of the boundary, with models in good agreement with 50 to 55 knots of 0.5 km flow in place across much of southeast Wyoming for areas mainly along west of I-25. High-res model guidance including the HRRR suggests widespread 55 to 65 MPH gusts developing between 15z and 21z prior to fropa w/ gusts decreasing to a slightly more- manageable 30 to 40 MPH in the late afternoon & evening behind the cold front. Have opted for a High Wind Watch from 15z Wednesday to 00z Thursday for much of southeast Wyoming given the fairly strong support from high-res model guidance, even though this event could be just a few hours in duration at most. All warning-criteria wind gusts should cease immediately post-fropa, but it will remain very windy nonetheless. In addition to the threat for high winds as the front approaches, banded snow is likely near the frontal zone with very strong frontogenesis at H7. This locally intense banding with possible snow squalls could drop a quick several inches of snow w/ significant travel impacts due to blowing snow as well. This seems like a scenario where Snow Squall Warnings may be favored over the need for Winter Weather Advisories as the threat for precipitation should be fairly short lived as well, so did not go w/ any winter- precipitation hazards at this time. The most dramatic, and likely most serious part of this storm will be the likelihood of extremely dangerous and life threatening wind chill values potentially exceeding 50-60 degrees below zero. Near- record breaking high pressure is still expected to slide southward across western Montana on Thursday w/ the GFS still suggesting the 1066 mb central pressure hear Helena which would exceed the record for the contiguous US set in 1983. As such, this will certainly be one of the coldest air masses to impact the area in recent years & perhaps decades. NAEFS/EPS guidance continues to indicate both 700 and 850 mb temperatures outside of climatology with several of the deterministic models (GFS/GEM/ECM) all showing H7 temperatures -30 deg C or colder over most of the CWA by 12z Thursday. As the cold- front blasts south on Wednesday afternoon, high-res models suggest that temperatures may fall 30 to 40 degrees in an hour or less. If fropa is accompanied by a snow squall, this may be a serious flash freeze event as well. Unlike the typical extreme cold events which are driven by lighter winds and radiational cooling, this one will be driven by strong winds w/ model soundings showing a deep, well- mixed boundary layer with average flow of 25 to 35 kts expected to reside within the lowest 1k feet AGL. That said, we could actually see temperatures of -25 to -35 deg F with sustained winds over 25- 30 MPH! This is extremely rare and is arguably more dangerous than your typical wind chill event where winds are less than 10 MPH. If there are any uncertainties at all, it is exactly how cold we will get as it is usually tough to see extreme cold when winds are this strong. Even so, NBM v4.1 has remained very consistent with 80-100 percent probabilities of -20 F or colder actual air temperatures & 50th percentiles MinT of -24 to -34 deg F Thursday night for most, if not all of the CWA. Official forecast was blend of 25-25-50 NBM 10th, 25th, and 50th percentiles, respectively. Prefer to hedge on the lower side for highly anomalous air masses. These MinT values, combined with the expected wind speeds yield WC values under 50 degrees below zero for most zones, perhaps even as cold as 70 degrees below zero near Lusk. Frostbite and hypothermia can develop in mere minutes in these conditions, and unfortunately death is a very real possibility in this scenario, especially with more vulnerable human populations. Farmers & ranchers are strongly advised to make final preparations to protect livestock. We cannot stress enough the seriousness of this situation! While the coldest wind chills will likely occur Wed night and Thu AM, highs on Thurs will remain below zero for many with winds staying elevated. There will not be much improvement whatsoever through Friday. Wind Chill Watches have been upgraded to Wind Chill Warnings area-wide. In the mountains, due to the expected significant orographics with a 180+ knot H25 jet (90-100 knot H5 jet), high-elevation snow fall accumulations of 8 to 15 inches will be possible in both the Snowy and Sierra Madre ranges. This combined w/ strong winds will create near blizzard conditions in the high country, and given the degree of wind chills, could be very serious should anyone become lost in these conditions. A Winter Storm Warning has been issued for these zones through 12z Thursday, followed by a Wind Chill Warning. .LONG TERM...(Thursday night through Monday) Issued at 426 AM MST Tue Dec 20 2022 The main story for the beginning tier of the extended forecast continues to be the unprecedented cold temperatures that will stick around on Thursday night into early Friday. Model guidance trends continue to show dangerous cold temperatures and wind chills through Friday morning. It wouldn`t be Wyoming if we didn`t also include the potential for our typical strong high winds to ramp up again during the extended period for the wind prone corridors as well. However, slightly above average temperatures are favored by the end of our extended forecast into the 30s and 40s. A dome of 1055mb surface high pressure will be firmly entrenched across central and northern WY by Thursday evening. Brutally cold temperatures will exist across a majority of the cwa to start the forecast period of Thursday night. 700mb temperatures of -15C to -25C are expected to persist across the NE Panhandle. However, model guidance from the GFS and Canadian deterministic is beginning to pinpoint areas where the pressure gradients are potentially going to tighten overnight. Pressure gradients of 5-15mb over the course of six hour periods will likely result in 700mb winds approaching 45-55 knots between 0Z-12Z Friday. Omega fields do show alternating positive and negative lift zones, and 500mb analysis depicts a mountain wave signature. It will be a tricky overnight forecast to pin down due to the potential for downsloping effects from the low and mid-levels warming adiabatically overnight. We could easily see negative sub-zero temperatures initially, and then quickly warming up into the positive teens to potentially 20s where the strongest wind gusts exists along and due east of the wind prone corridors. Strong northwest flow aloft is also anticipated to create orographic enhancement of snow showers for the Snowy/Sierra Madre mountains as a shortwave disturbance approaches the Intermountain west from early Friday through Friday afternoon. The cold air will persist through Friday evening for the NE Panhandle forecast zones as strong CAA continues to funnel into the region. Forecast highs in the single digits to teens are expected at this this point for the NE Panhandle. However, southeast WY will see a rise in temperatures as downslope winds continue to adiabatically warm a large portion of those areas. Wouldn`t be surprised to see 20s to potentially near 30 degrees F in localized areas due east of the Laramie Range on Friday, but there will be a sharp gradient. Have not bumped up temperatures to reflect this entirely as some of the model guidance is not in agreement with this solution presently. WAA will occur beginning Friday night as heights in the lower and mid-levels begin to increase thanks to an upper level ridge amplifying. Some members of the extended guidance have a shortwave riding along the northwest flow aloft Friday night into Saturday afternoon. This shortwave is expected to slide to our south with most of its energy, bringing snowfall to the mountains west of the Laramie Range, but QPF looks low. Daytime highs will be in the 20s and 30s on Saturday. Localized downslope warming is possible on Saturday east of the Laramie Range thanks to gusty winds making a return to the area. At this time of inspection, the wind prone/gap corridors of Bordeaux and Arlington/Elk Mountain are favored for strong winds of 50-60mph on Saturday. Additional upper level ridge amplification is expected on Sunday into Monday, with near seasonal to above average temperatures in the 30s and 40s. Tuesday will see additional upper level ridge amplification, and daytime highs in the 30s and 40s are also favored, with possible localized areas as warm as the lower 50s. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 420 PM MST Tue Dec 20 2022 Wyoming TAFS...VFR, with ceilings lowering to low VFR after 20Z Wednesday.
