Area Forecast Discussion
National Weather Service Bismarck ND
951 PM CDT Wed Sep 5 2018 .UPDATE... Issued at 935 PM CDT Wed Sep 5 2018 Main forecast problem for the evening update is clouds/pops in the west and temperatures in the east. Mostly clear skies across western and central ND this evening. Band of clouds in the sw/sc remains but continues to slowly diminish as it lifts north. Warm advection does pick up overnight and moistening of the mid levels is noted in latest RAP soundings over western ND. Question is will we see any precipitation. If we do it will likely be light in the overnight hours and early morning Thursday. With only slight pops in there now, we did keep some slight chance pops going although not certain about any measurable precipitation. Some of the CAMS are still depicting shower activity developing from around Beach up through Watford City and Williston after midnight and spread this into the north central during the morning. Used this areal coverage as a general guide for some slight chance pops. Think chances will improve over the north central as we go through the day on Thursday. The other question is temperatures tonight. Surface high currently over the Turtle Mountains will drift slowly southeast overnight. Dew point temperatures are currently in the 30s across much of the west, but we do expect warm advection to increase here overnight. Dew points are ranging from the mid 30s to mid 40s over central ND and we should see a longer duration of decent radiational cooling here. We lowered temperatures a little over the central portion of the state. UPDATE Issued at 621 PM CDT Wed Sep 5 2018 Clear skies across most of western and central ND early this evening. The exception being a band of mid clouds from around Beach and Dickinson southeast to Fort Yates and Linton. Updated sky cover to reflect this with clouds slowly eroding. We do expect additional development later tonight in the west when warm advection increases. Otherwise no changes to the going forecast. && .SHORT TERM...(This evening through Thursday) Issued at 232 PM CDT Wed Sep 5 2018 Increasing warm air advection associated with a developing warm front and sufficient instability will lead to increasing chances for showers/thunderstorms, mainly northwest and north central Thursday. A Marginal Risk for severe thunderstroms exists Thursday for northwest and north central North Dakota. Latest visible satellite imagery shows sunny conditions north and mid level clouds/mostly to partly cloudy conditions across southwest and into portions of south central North Dakota. Surface high pressure in north central ND will shift east into western Minnesota this evening. Low level southeast to southerly winds will ensue around the high, initiating moisture advection across western North Dakota tonight and Thursday. Global models are hinting at some showers across far western North Dakota late tonight into Thursday morning. The HRRR only goes out to 11z and by that time it shows isolated showers far west. Will give this some play and mention a slight chance of showers west 06z-12z Thursday. Surface low pressure and warm front develop over southeastern Montana Thursday and Friday, which extends through central North Dakota. This front will aid in low level convergence/lift, and with greater instability ensuing as persistent low level southerly winds aid in moisture/temperature advection, surface dewpoints rise into the mid 50s. Both the NAM/GFS show weak CAPE at around 1000 J/Kg with deep layer shear between 30kt and 40kt Thursday and Friday. As a 700mb shortwave rides atop the surface warm front Thursday afternoon, expect showers and thunderstorms across northwest and north central. Mid level lapse rates/700-500mb average around 7C/Km Thursday. Given the instability parameters, a few thunderstroms could become strong, along with with the possibility of an isolated severe thunderstorm. After collaborating with SPC, it was decided to add a Marginal Risk for severe thunderstorms Thursday northwest and north central. Warmer Thursday southwest through south central (within the warm sector of the developing warm front) with highs in the lower 80s southwest, to mid 70s for most of central North Dakota. Highs in the mid 60s (north of the warm front) will reside over northern North Dakota. .LONG TERM...(Thursday night through Wednesday) Issued at 232 PM CDT Wed Sep 5 2018 The warm front slowly advances north to the border Friday night. In doing so, and until that happens, continued low level southerly winds and moisture/warm air advection will drive chances for thunderstorms along and north of the warm front. A couple mid level shortwaves riding atop the front will also aid in ascent maintaining chances for showers and thunderstorms Thursday night through Friday. The best chances continue to reside across the north. Potential for a few strong thunderstorms, and possibly an isolated severe thunderstorm as the environment will be similar to Thursday. A strong mid level shortwave and cold front will progress from west to east Saturday through Sunday morning. It appears central North Dakota will remain dry through the day, with scattered showers and thunderstorms west in the afternoon. Precipitation will then shift across central North Dakota Saturday night. There is some wiggle room ahead of the front for strong to possible severe thunderstorms, with increased CAPE, but weaker deep layer shear. So storms may be more pulse type and vertical. The weather pattern overall remains active through at least mid week as a longwave west coast trough evolves. This puts western/central ND within an active/moist southwest flow aloft with periodic chances for showers and thunderstorms. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 935 PM CDT Wed Sep 5 2018 Vfr cigs/vsbys this taf period. A thinning sct/bkn mid level cloud deck remains near KDIK this evening. Otherwise expect a skc across the terminals this evening. Increasing clouds are expected to develop in the west after midnight with a threat of showers increasing at KISN between 08z and 16z Thursday. We did include a vcsh here. KMOT will have increasing chances for morning showers and afternoon thunderstorms tomorrow. Rest of the terminals should have no threat of precipitation through 18z Thursday. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && $$ UPDATE...TWH SHORT TERM...KS LONG TERM...KS AVIATION...TWH
National Weather Service Eureka CA
248 PM PDT Wed Sep 5 2018 .SYNOPSIS...Seasonably warm and dry weather conditions will persist across the interior for the next several days. Coastal areas will be cool and mostly cloudy with perhaps some afternoon sunshine through the end of the week. && .DISCUSSION...Stratus has been covering much of the coast today. The marine layer appeared to be relatively shallow, around 1000 feet or less with a light offshore wind component. Persistent coastal stratus will be around for the next couple of days as north to northwesterly winds slowly return to the nearshore waters. Confidence is not high there will be much clearing or sunshine on Thursday except in the coastal river valleys. High resolution models indicate higher chances for clearing south of Cape Mendocino on Friday as northerly winds increase offshore. Temperature trends were by means definitive today. As of 2pm, some sites susceptible to marine air intrusion have been 5 to 10F cooler. Meanwhile, most interior sites were about the same as the day before to a few degrees warmer. Confidence is not high there will be substantial cooling over the two days, Thursday and Friday. Latest statistical guidance as well as all the models indicates subtle warming through Friday as a broad ridge aloft builds offshore. Granted we will not have a pronounced offshore flow pattern to suppress the marine air from trickling into the coastal river valleys. A couple of dry cold front will pass across the area heading into the weekend and into the early portion of next week. The first one should knock interior temperatures down this weekend to around normal. Temperatures in the interior will likely trend below normal early to mid next week behind the second front. No rain is expected with any of these fronts. Drizzle with be a possibility through. These fronts may eventually disrupt or completely wipe out the marine layer for greater sunshine at the coast. && .AVIATION...North Coast weather remained nearly static as stratus continued to engulf much of the immediate and nearby coastal areas. One notable difference from yesterday was that by early/mid-morning, skies were mostly clear at ACV and CEC except for a layer of smoke at CEC. Overnight IFR/LIFR clouds besieged the coast and continued into the afternoon today, assisted by several eddys offshore. A late morning CEC pirep reported cloud tops less than 1000 feet with a semi- diffuse smoke layer above. Inland areas: Clear skies prevailed and will continue so, although local Vis smoke/haze (FU/HZ) restrictions possible in the morning again due to wildfires. Low clouds moved within a few miles of UKI, but stayed south of the airport. Stratus advection for Thursday seems unlikely considering today. However looking at the HRRR SFC RH, at least few to scattered stratus is possible (with a south flow). /TA && .MARINE...issued at 327 AM PDT Wed Sep 5 2018. The surface pressure gradient along the coast is forecast to weaken during the next 12 hours, which will lead to the dissipation of gusty north winds and steep wind waves by Wednesday afternoon. Thereafter, several days of relatively calm marine conditions will be followed by a strengthening surface pressure gradient resulting in the redevelopment of small craft winds/waves over the southern coastal waters. Otherwise, a 2-4 foot southerly swell oscillating between a period of 10 to 20 seconds will spread north across the waters during the next seven days. && .EKA WATCHES/WARNINGS/ADVISORIES...

National Weather Service Austin/San Antonio TX
814 PM CDT Wed Sep 5 2018 .UPDATE... A moist atmosphere remains in places across South Central Texas, with 00Z upper air sounding data showing precipitable water values over 2" at both CRP and DRT. Ongoing shower and thunderstorm activity through portions of the Hill Country is indicated by HREF and HRRR to decrease in coverage during the late evening hours. Re-development is possible of showers and storms overnight, favoring western areas of the Hill Country and Rio Grande, closer to a weak mid level inverted trough and better low level flow. Re-configured evening PoPs based on current radar trends and overnight PoPs based on forecast thinking above. && .PREV DISCUSSION... /ISSUED 610 PM CDT Wed Sep 5 2018/ AVIATION... Scattered showers and thunderstorms are ongoing in the area. Maintaining VCSH for KAUS/KSAT/KSSF to accommodate continued development due to colliding outflow boundaries, before weakening and dissipating this evening after sunset. MVFR ceilings returning overnight and into the morning before another round of shower development starts tomorrow afternoon. Surface boundary nearing KDRT tomorrow will aide in further shower development. PREV DISCUSSION... /ISSUED 243 PM CDT Wed Sep 5 2018/ SHORT TERM (Tonight through Thursday Night)... The upper air analysis this morning showed a trough over the southwestern states with a ridge over the eastern half of the country. The mid-level flow is very weak. The surface pressure gradient is not well defined and winds were light and variable across our CWA. The weak upper level flow will continue during this period. Scattered showers and thunderstorms will continue across the region through this period. PW will remain high and there will be pockets of locally heavy rain possible. LONG TERM (Friday through Wednesday)... The upper pattern will remain stagnant into the beginning of next week. This will mean continuing chances for showers and thunderstorms into the weekend. A weak surface boundary will move down through north Texas and toward our CWA. This may provide better focus for convection to develop and perhaps a better chance for heavy rain over the weekend. The WPC seven day rainfall totals are between 2 and 4 inches of rain across our CWA with the higher amounts out west. Locally heavy rain will be possible each day and could lead to some flooding. && .PRELIMINARY POINT TEMPS/POPS...

908 PM CDT Wed Sep 5 2018 ...GORDON CONTINUES WEAKENING AND TRACKING NORTHWEST ACROSS WEST- CENTRAL MISSISSIPPI... .UPDATE... Updated for evening discussion. && .DISCUSSION... Local radar showed a band of very heavy rainfall over east central Mississippi associated with Tropical Depression Gordon which was noted over Humphreys county at 900PM. This band extended north from western Newton county and curled to the northwest across Grenada county. A Flash Flood Warning has been issued for a portion of the line so the Flash Flood Watch has been extended until midnight for the eastern counties within the warning. T.D. Gordon will continue tracking slowly to the northwest tonight and additional bands of heavy rainfall will be possible especially closer to the Interstate 55 corridor and across the northern portions of the delta. The tornado threat has diminished for the remainder of tonight. Pops have been lowered across the southwest half of the area the remainder of the night as well. Temperatures were generally on track. /22/ Prior discussion below: Rest of this evening & tonight through Thursday: Overall main focus in the near term continues to be the severe threat through late afternoon to early evening & then the heavy rain & flash flooding threat overnight. Tropical Depression Gordon has continue to slowly drift across the area today, leading to slow west-northwest progression. Due to the very slow westward movement of the remnants of Gordon, expect continued potential for brief tornadoes & gusty showers. Some storms have exhibited these features already this afternoon so will have to continue to monitor for any features as there is ~30kts effective bulk shear & ~150-200 m2/s2 effective SRH. In addition, with high anomalous PWs & any training or convergent feeder bands, some heavy rain & flash flooding potential will continue into the evening. Expect these storms to slowly weaken somewhat into the evening but the flash flooding potential to continue into the overnight hours. Expect remnants of Gordon to only slowly drift to the northwest overnight, leading to continued moisture feed & transport with nearly 340-345K+ 850 & 925mb Theta E. CAM & HREF guidance has slowly begun to back off somewhat on the overall totals. HRRR continues to show the convergent axis somewhere near & west of the I-55 corridor while some other guidance is more confined to a localized area. Still totals in some CAM/HREF guidance are in the 3-5 inch range. Right now, overall with high PWs & good moisture convergence, it is hard to overall paint the exact area of heavy rain. But it looks as though as Gordon slowly drifts northwest into the ArklaMiss Delta overnight, convergence along the north & eastern side could help rainfall totals pile up in these feeder bands. Therefore, continued mention of 2-4 inches with locally higher amounts being possible. Continued to advertise the "Elevated" in the HWO/Graphics & Flash Flood watch for the Delta & slowly drifting northwest into the overnight & early morning hours on Thursday. Will have to monitor if that needs to be expanded or not. With high moisture lingering in the region, expect high rain chances & lower temperatures towards raw guidance again on Thursday. Expect some localized heavy rain potential to remain across the ArkLaMiss Delta into midday while more storms will redevelop into the afternoon. Right now, will have to keep a close eye on any areas that received any heavier rainfall overnight & into the morning. But with moisture convergence & overall column of moisture depth decreasing, opted to not mention anything for flash flooding in the graphics & HWO for now. In addition, shear is somewhat relaxing but there could be around 15-20kts 0-2km & 0-3km bulk shear & slightly better lapse rates, couldn`t rule out a couple of stronger storms again on Thursday. However, tornado potential remains to look less likely than today. /DC/ Thursday night through mid week next week: By Thursday night, the remnants of Gordon will be well west of the ArkLaMiss where it will begin to merge with an approaching shortwave as it crosses the Plains. A left over convergence axis associated with the remnants of Gordon will still exist over the western portions of the region on Friday. This along would deep available moisture will result in developing showers and storms mainly along and west of the MS River. As we get into the weekend, a front associated with the shortwave that Gordon assimilated will begin to approach the region from the west. The front is expected to move into the region on Sunday before stalling. This frontal boundary will serve as a focus for showers and storms through at least mid week. The best coverage of storms will exist during the day time each day. Rain and storms will hold && .AVIATION... 00Z TAF discussion: Tropical Depression Gordon was noted on radar mid way between HKS and GLH at 2330Z. Wind gusts have died down but widely scattered SHRA were wrapping around the center and wl result in IFR/LIFR conds at TAF sites tonight. Otherwise, MVFR cigs wl lower to IFR/LIFR after midnight along with vsby restrictions. These conds wl cont through 15Z Thu morning before gradually improving to VFR conds by 21Z. Numerous SHRA with isold TSRA are expected over the nw Thu aftn with scattered SHRA and isold TSRA expected elsewhere. /22/ && .PRELIMINARY POINT TEMPS/POPS...

National Weather Service Miami FL
831 PM EDT Wed Sep 5 2018 .UPDATE... The showers and thunderstorms that been occurring over the western areas of South Florida have pushed off into the offshore Gulf waters this evening. The HRRR along with the other short range models are showing that some showers and thunderstorms will develop over the Atlantic waters overnight and push into the east coast metro areas mainly after midnight,as the tropical wave and upper level low approaches South Florida. Therefore, will continue with the low end chance of showers and a few thunderstorms for the east coast metro areas for mainly after midnight tonight. Rest of the forecast looks good at this time and no other changes are planned. && .UPDATE...54/BNB .PREV DISCUSSION... /issued 741 PM EDT Wed Sep 5 2018/ AVIATION... An evening lull in convection will eventually give way to increasing convection over the Atlantic waters overnight which could impact the east coast terminals through the morning. Terminals directly impacted by convection could have brief bouts of sub-VFR conditions. Showers and thunderstorms are expected to increase in coverage late morning into the afternoon. Generally easterly flow with some gusty variability around convection. Short-fused amendments will be necessary with convection. && PREV DISCUSSION... /issued 415 PM EDT Wed Sep 5 2018/ .SOME STRONG STORMS POSSIBLE THURSDAY AFTERNOON INTO FRIDAY... .MODERATE RISK OF RIP CURRENTS EAST COAST BEACHES THROUGH THURSDAY... DISCUSSION... * THURSDAY AND FRIDAY An upper level low will move westward from the Western Atlantic waters through South Florida late Thursday into Friday, as a tropical wave over the eastern Caribbean sea extending northward into southern Bahamas moves west northwest across the region. This will bring in deeper moisture to South Florida for late this week. Therefore, scattered to numerous showers and thunderstorms are expected across South Florida for Thursday into Friday. The 500 mb temps will also be cooling down to -9 to -10C over South Florida late Thursday evening into early Friday morning. This will allow for some strong storms to develop over the region especially between Thursday afternoon into Friday. The primary impacts from the strong storms will be gusty winds, hail, and frequent lightning strikes. * THIS WEEKEND Both the upper level low and the tropical wave will continue to move west northwest into the Gulf of Mexico this weekend, as the high over the Western Atlantic waters weakens. This will allow for the steering flow to be more southerly over South Florida keeping the deeper tropical moisture in place. Therefore, the scattered to numerous showers and thunderstorms will continue over the region this weekend with the best coverage over the Lake Okeechobee area. EXTENDED FORECAST... The high will then rebuild into South Florida for early next week allowing for the easterly wind flow to return to the region. This will lead to more of the night time and morning showers and thunderstorms along the east coast. and afternoon and evening showers and thunderstorms interior and west coast. MARINE... The winds will be easterly at 10 to 15 knots tonight into Thursday before decreasing to 10 knots or less Thursday night into Friday. The winds will then become southerly at 10 knots or less this weekend. This will keep the seas at 3 feet or less in the Atlantic waters and 2 feet or less in the Gulf waters through the weekend. BEACH FORECAST... The threat of rip currents will continue through Thursday before decreasing Friday into the weekend along the east coast beaches of South Florida due to the decrease in the wind speeds. && .PRELIMINARY POINT TEMPS/POPS...

821 PM PDT Wed Sep 5 2018 .DISCUSSION...06/00Z NAM in. Some cumulus developed over the Cascades around Crater Lake, extending north to northeast to the Chemult area. Cumulus also developed over Modoc and Lake counties, but no lightning or precipitation was recorded. Those clouds are now dissipating. Other than that, there are areas of marine stratus along the coast and over the near shore coastal waters, and, of course, smoke from area wildfires. As far as smoke goes, the HRRR Smoke Model is indicating a significant increase in smoke across eastern Douglas, Josephine, Jackson, Klamath, and northeastern Siskiyou counties this evening, with smoke settling into the valleys from Grants Pass to Ashland to Yreka to Klamath Falls by early Thursday morning. Guidance suggests the smoke will thin some Thursday before another round comes in on northwest winds Thursday afternoon and evening. There will be cooler temperatures and a greater marine influence across the area Friday afternoon into this weekend, so the smoke will probably begin to thin out some then. Southwest flow aloft has developed over the Pacific Northwest due to a long wave trough digging offshore. This trough will remain out there through at least early next week, and short waves ejecting from the trough will move onshore with most of the energy directed north of the Medford CWA. Temperatures will cool into Friday, and it will remain dry except for possibly some drizzle along the coast and over the coastal waters. Winds will be gusty east of the Cascades in the afternoons and evenings. The first significant short wave will move onshore Friday night, and it will push a weak front onshore with it. This won`t bring much in the way of precipitation to the area, and the bulk of what there is of it will fall along the north coast and the northern portion of the Umpqua Basin Friday night into Saturday morning. After that, there will be another stretch of dry weather through the rest of the weekend. The next significant short wave will move onshore Sunday night into Monday, and it looks to be similar to the Friday night front in terms of precipitation amounts and coverage. Extended discussion from the Wednesday afternoon AFD...Monday through the week. Confidence is high that we will see a broad low pressure trough build into the Pacific Northwest early next week, lowering temperatures to below normal values beginning about Tuesday. The precipitation portion of the forecast, as is usually the situation, is much less certain. However, it does appear that some weak fronts will bring light amounts to Coos and Douglas counties early next week. Mid-late week rain chances increase south and east of there, but model guidance is very uncertain in the details. Thus, for now, through Wednesday probabilities of rain in the forecast are low. Expect these, most likely, will increase as we move into the future and confidence grows in the details. The pattern is certainly looking increasingly favorable for precipitation to occur mid-late next week. -Lutz && .AVIATION...For the 06/00Z TAFs...IFR/LIFR will prevail from Cape Blanco southward early this evening, then expand northward to fill in along the entire coast late this evening into Thursday morning. The marine layer is pretty shallow, so not expecting it to reach Roseburg, but some locations in the lower Umpqua Valley from Elkton to Reedsport and also the Coquille Valley near Powers will likely end up with IFR/LIFR. Lower conditions should improve to VFR Thursday afternoon, but may have difficulty breaking along portions of the immediate coast. VFR will prevail inland, however, wildfire smoke will limit visibility to MVFR/IFR in some areas, especially near the Klondike, Miles, Natchez and now Delta fires. -Spilde && .MARINE...Updated 820 PM PDT Wednesday, 5 September 2018...Lighter winds and lower seas are expected tonight. The small craft advisory for hazardous seas has been cancelled since seas have lowered to 5 feet or less. Relatively light winds and low seas are expected Thursday through Friday as high pressure moves over the waters. A weak frontal system dissipates over the waters Friday night, and this will be followed by a series of weak fronts this weekend into early next week. As a result, winds will be variable and relatively light with continued low seas. Northwest swell could increase early next week. -Spilde && .FIRE WEATHER...Updated 800 PM PDT Wednesday 5 Sep 2018...Hot and dry conditions with breezy afternoon winds will continue through Friday. Although it will continue to be dry, winds won`t be quite as strong Thursday afternoon as it was Wednesday, so conditions won`t be as critical. Winds will increase again on Friday afternoon ahead of an incoming dry front, but will still be less than what it was Wednesday. Critical fire weather conditions are not forecast at this time. A dry cold front will move through Friday night into Saturday morning. Models are keeping precipitation mainly north of the area, so there is only a slight chance of light rain along the coast north of Cape Blanco and in the far northern portions of FWZ 616 and 617. Temperatures will continue to cool behind this front through the weekend, and even more so into early next week. Models have been fairly consistent in bringing a trough over the PacNW early next week and depending on how far south the trough ends up, there could be increased chances of precipitation. While confidence is low in the details, confidence is increasing that there will be a transition to a cooler and possibly wetter weather pattern by this time next week. && .MFR WATCHES/WARNINGS/ADVISORIES...
