322 PM CST Sat Nov 9 2019 Under northwesterly flow aloft, surface pressures across the PAH forecast area will gradually drop through the weekend as southwesterly surface winds continue ahead of a vigorous cold front/surface trof. High pressure over the Deep South, and the dry fetch of the westerly 850 mb winds will keep the forecast rain- free through at least Sun afternoon. This pattern will be conducive to warmer overnight lows in the 30s, and highs on Sun in the 60s, which is near the seasonable average.
An upper level low to the southwest of Arizona is spreading high clouds across the region this afternoon. Sunday will feature more of the same, with high clouds persisting across northern Arizona as the upper low slowly moves eastward.
High pressure over SE Texas today has allowed for light winds and for temperatures to increase into the mid 60s for much of the area.
Rain will mostly be on the back side of an arctic cold front that is expected to move across the Midsouth by midday.
318 PM CST Sat Nov 9 2019 The arctic cold front is moving through MT and ND this afternoon and should enter northern Nebraska around 12z Sunday morning. The NAM model soundings suggest several hours of low level saturation near the sfc to around 875 mb which will support drizzle and freezing drizzle.
Southwest winds expected to continue this evening and most of tonight, until a weak cold front enters the northwest part of the Combined Texas and Oklahoma Panhandles.
With very little cold air advection to speak of, low temperatures tonight to remain above freezing in the lower 40s.
823 PM EST Sat Nov 9 2019 A much cooler and drier post-frontal airmass continues to settle across east central Florida as high pressure builds in across the southeastern U. The lower dewpoints, mostly clear skies, and winds becoming light should allow temperatures to fall into the mid to upper 50s west of I-95 and also the Volusia Coast. For coastal areas farther south, low temperatures are expected to remain in the lower to possibly mid 60s with winds slightly stronger and retaining more of an onshore component.
430 PM MST Sat Nov 9 2019 The axis of the all-too-familiar ridge of high pressure can clearly be seen on satellite this afternoon with ample midlevel moisture streaming on the outskirts of it up in Montana. With high pressure in control sunny skies, light winds and above normal temperatures have persisted across eastern Utah and western Colorado today. This trend will continue overnight, though the ridge will be ushered further west as a Pacific trough and associated cold front progress across the Intermountain West. Unfortunately the cold front is still not projected to bring much excitement to our forecast area with increased mid and high level clouds being the primary alteration beginning Sunday afternoon. Accumulations will be minimal, generally up to a few tenths of an inch with maybe an inch possible at the highest peaks of the Park Range.

This will exit the region later this evening, and then a strong cold front will push through the region on Sunday.
550 PM EST Sat Nov 9 2019 Temperatures will continue to moderate into Sunday ahead of a strong cold front. Lows tonight will be near freezing followed by highs Sunday well into the 40s.
Otherwise, winds will veer to SW Sun in advance of the next cold front. Temperatures will warm steadily into the 60s and a few locations will touch the lower 70s under clear skies and light winds. Tonight will be much warmer than the past few nights as return flow advects low-level moisture into the region and high clouds prevent sufficient radiative cooling. This warm up will be short-lived however, as a cold front looms to the north. A large upper-trof will begin to deepen across the Midwestern U.
409 PM EST Sat Nov 9 2019 Temperatures will continue to recover into Sunday ahead of a strong cold front. Lows tonight will be near freezing followed by highs Sunday well into the 40s. Dry conditions will persist into Sunday before a strong cold front arrives Sunday night.
This will allow a cooler and drier airmass to hold over the area, with cool morning temperatures giving way to mild and sunny afternoons.
One more warm and pleasant afternoon on tap Sunday before the bottom drops out as temperatures plummet Monday behind Arctic cold front. Areas of showers will begin to develop late evening Sunday, becoming more widespread Sunday night as the cold front moves into northeast Oklahoma. At this time, it appears the best chance for minor snow accumulations of less than an inch will be possible across northwest Arkansas in the higher terrain.
1229 AM EST Sun Nov 10 2019 Temperatures will continue to moderate into Sunday ahead of a strong cold front. Lows tonight will be near freezing followed by highs Sunday well into the 40s.
Backing of winds along the reef from north indicates there is a bit of an associated lower tropospheric trough. High pressure building into the southeast has already managed to increase the pressure gradient to near 8 mb from Jacksonville to Havana, and likely to remain that way through the night. Near-term hourly guidance indicates a decrease in the showers and sprinkles as the low-level secondary trough passes into the Straits. After and initial wind surge after cold front passage, northeast winds have become a uniform 20 to 25 knots sustained along the reef with freuqent gusts 25 to 30 knots. High pressure over the southeast U.
/issued 252 PM CST Sat Nov 9 2019/ Tonight will continue with the quiet theme from today as upper ridging sets in over the region. Upper ridging will stay in place for most of tomorrow ahead of an approaching cold front. The cold front is still expected to roar through during the early morning hours Monday. As freezing temps aren't expected until mid day or so Monday there currently does not appear to be a threat for freezing precip.
Much milder tonight with the mercury holding in the low to mid 40s for lows. It looks as though the cold front will reach our far northwestern corner in the early afternoon hours, and the boundary should reach our Plateau in the evening.
Strong cold front will begin to edge into far northern Oklahoma late in the period so included a wind shift at KBVO. One more warm and pleasant afternoon on tap Sunday before the bottom drops out as temperatures plummet Monday behind Arctic cold front. Areas of showers will begin to develop late evening Sunday, becoming more widespread Sunday night as the cold front moves into northeast Oklahoma. At this time, it appears the best chance for minor snow accumulations of less than an inch will be possible across northwest Arkansas in the higher terrain.
258 AM CST Sun Nov 10 2019 The first cold front was sinking south into northern Kansas early this morning.
A second weak disturbance will track southeast across the area Sunday night, followed by a return of high pressure aloft early in the upcoming week. These clouds will continue to move across northern Utah Sunday as the associated cold front from the disturbance dips into northern Utah. Temperatures across northern Utah will be a couple of degrees warmer tonight due to these clouds but behind the cold front on Sunday temperatures will be a few degrees cooler than today.
/issued 830 PM EST Sat Nov 9 2019/ Existing forecast remains on track as clear skies continue this evening under high pressure and cool/dry air continues to filter into the region via north/northeast flow.
100 AM EST Sun Nov 10 2019 High pressure will dominate through Monday. Freezing temperatures will occur once again during the early morning hours today.
At the surface, high pressure is centered over Georgia, and low pressure is centered over northern Missouri. Tonight, an advancing cold front will begin to push low level clouds overhead during the late evening for areas in southern Indiana before blanketing all of central Kentucky overnight.
1149 PM CST Sat Nov 9 2019 The arctic cold front is moving through MT and ND this afternoon and should enter northern Nebraska around 12z Sunday morning. The NAM model soundings suggest several hours of low level saturation near the sfc to around 875 mb which will support drizzle and freezing drizzle. The arctic high pressure system, despite it's 1048mb strength, moves off south and east very quickly.
209 AM EST Sun Nov 10 2019 High pressure will dominate through Monday. Freezing temperatures will occur once again during the early morning hours today.
Temperatures at DIA dropped into the lower 40s F from the low 50s F right after it passed. Dry and mild conditions will remain in place through Sunday, before the next stronger cold front moves in Sunday evening. There is a weak surge of cooler air over which reaches the northeast corner of the state late tonight. This will result in cooler temperatures across the plains Monday, but overall above normal temperatures can still be expected. The I-25 Urban Corridor will most likely see highs pushing into the lower 60s. Models continue advertising a strong cold front moving into northeast Colorado tomorrow evening. This should lead to a period of drizzle/or freezing drizzle overnight. The upper disturbance accompanying the cold front will quickly move onto the southern plains, taking the areas of precipitation with it.
338 AM EST Sun Nov 10 2019 The center of high pressure will become elongated as it settles across the Carolinas through tonight.
1108 PM EST Sat Nov 9 2019 High pressure will dominate through Monday. Freezing temperatures are expected once again tonight, along with some frost.
Winds will start out southwest veering to more northerly behind a passing cold front as we go past 18Z to the end of the TAF period. Southwest winds expected to continue this evening and most of tonight, until a weak cold front enters the northwest part of the Combined Texas and Oklahoma Panhandles.
247 AM CST Sun Nov 10 2019 Warmer conditions were observed overnight across extreme southeast Kansas and the Missouri Ozarks. Dry weather is expected through the afternoon, however, precipitation will eventually develop across the region tonight and especially Monday as a strong cold front surges into the region. Temperatures will drastically cool down, creating a mix of rain, sleet, snow, and possibly some freezing rain Monday.
323 AM EST Sun Nov 10 2019 Beautiful weather is in store today as high pressure settles across the Southeast in the wake of yesterday's cold front. Highs today are forecast in the low to mid 80s, but the apparent temperature will actually be a touch lower due to the low humidity and breezy conditions. Low temperatures tonight are forecast in the low 60s across the Lake region to the low 70s right along the East Coast under mostly clear skies.
High pressure moving further off to the east will allow for winds to shift out of the SSE. High pressure nearly overhead will keep winds light through the night allowing for ideal radiational cooling. Although temperatures are expected to be a few degrees warmer than last night (owing to the absence of CAA) patchy frost will again be possible across parts of central Louisiana where temperatures are expected to fall into the mid 30's. Forecast philosophy remains largely unchanged with regards to the well advertised strong cold front progged to push through the area late Monday.
An upper level low to the southwest of Arizona is spreading high clouds across the region this afternoon. Sunday will feature more of the same, with high clouds persisting across northern Arizona as the upper low slowly moves eastward. A weak cold front will brush the Four Corners region on Monday, leading to locally breezy northeast winds.
Temps will fall another degree or two, with isolated locations reaching freezing. A fairly pleasant day is anticipated across the TN Valley, as a weak ridge moves eastward over the area. This will result in mostly clear skies and temperatures warming into the lower to mid 60s. An upper trough will begin to dig southward and into the Plains tonight, with southwest flow returning over the TN Valley. This return flow will filter moisture northward, keeping overnight lows from falling below the lower 40s. The trough will approach the Mississippi Valley during the day Monday, pushing a cold front towards the TN Valley. These showers will overspread the area Monday night as the cold front quickly sweeps through the area.
A strong cold front will enter northeast OK after 06Z and should move south of KTUL/KRVS toward 12Z. Cold front extends across the central Plains early this morning, and it will move into northeast Oklahoma after midnight. There may be a brief period of freezing rain across portions of Osage County early in the morning, but forecast soundings suggest enough cold air will quickly move in, which will likely result in a sleet/rain mix.
613 AM EST Sun Nov 10 2019 High pressure will dominate through Monday.
858 AM EST Sun Nov 10 2019 Dry conditions and warmer temperatures are expected today before the next area of low pressure brings rain Monday, and light snow by Monday night.
A weak upper disturbance will make its way across the state today while a surface cold front sweeps through later tonight. Winds will shift down-valley late tonight after the front passes, and cooler temperatures are expected for Monday.
433 AM CST Sun Nov 10 2019 bringing cooler temperatures and northerly winds to the area. Strong high pressure will settle across the area behind the departing system Monday.
Cold front has crossed the region and precip is lagging behind. A period of freezing drizzle is expected to follow this period of fog, as temperatures continue to fall, but are still to warm to develop snow, according to soundings. Temps in south-central Montana, however, will start to warm up, with Livingston reaching 40 degrees, and Billings climbing to around freezing, as upper level ridging builds back into the region.
High clouds are streaming over the region which may limit high temperatures a bit and went a bit cooler than previous forecasts as a result.
Warmer conditions were observed overnight across extreme southeast Kansas and the Missouri Ozarks. Dry weather is expected through the afternoon, however, precipitation will eventually develop across the region tonight and especially Monday as a strong cold front surges into the region. Temperatures will drastically cool down, creating a mix of rain, sleet, snow, and possibly some freezing rain Monday.
As of early Sunday morning, a cold front had pushed south into IA/NE, but the colder air was still lagging up in North Dakota. Still appears that the central/western parts of the state are where the highest snow accumulations will occur, probably enhanced by upslope flow for a time today. Although that said fzdz/sn may make roads a bit slick this morning over that area as temperatures drop below freezing.
Deteriorating flight conditions are expected tonight as widespread stratus develops and a cold front moves through the area. Freezing rain could even affect KWWR (confidence is too low to include in this TAF issuance). In addition, southerly winds will shift to the north as the cold front moves through. A strong cold front will enter northwestern Oklahoma later this evening and pass quickly through central Oklahoma by sunrise Monday. This feature may give a period of light freezing rain near the Kansas border before the lift passes to the east. The main story will be the very wind and cooler conditions.
The strong cold front will arrive tomorrow between 12-15Z and quickly move through the CWA bringing a very cold Canadian airmass. Model cross sections still show a prominent warm layer about 3kft thick and +2C to +3C making freezing rain the most likely precip type in the Big Bend with some sleet possible closer to I-10. Instead, the biggest threat for accumulations and slick roads currently appears to be in the Big Bend with US 90 east of Marfa potentially seeing up to a tenth of an inch of ice accumulation from freezing rain.
The cold front remains just north of the CWA at this time. Tonight, guidance depicts an upper trof approaching the area with continued low level WAA across much of the area. Further north, large scale lift from the approaching trof and ULJ, as well as mid level frontogenesis, will support snow further back into the cold air. Have held off on any headlines given the low impact currently expected. Behind the precip, cold air will push into the region, with temps bottoming out in the low teens to near 10 degrees. The next upper trof and associated cold front arrives Wed night. Tilly A cold front will push south through the area today causing SW winds to become northerly. SPECIFICS FOR KSTL: Winds will become northerly behind a cold front today.
353 AM CST Sun Nov 10 2019 Strong jet level winds will dive into the back side of the long wave trough later today that is located over the Canadian/US border along with a stalled front.
652 AM EST Sun Nov 10 2019 High pressure will dominate through Monday.
/issued 435 AM CST Sun Nov 10 2019/ (Today and Tonight) Looks for warmer temperatures today across West Central Texas due to strengthening 850 mb thermal ridge and low level south to southwest flow. A strong cold front is still on track to move across the area on Monday.
Winds will be light out of the southwest to west until a cold front moves through in a few hours, around 14Z to 15Z. During this time period some light drizzle to freezing drizzle will be possible.
Meanwhile, an upper-level area of low pressure will continue to move over southern CA and northern Baja and push further south by tonight as an upper-level ridge of high pressure builds along the West Coast.
242 AM MST Sun Nov 10 2019 09z surface analysis had cold front from western MT to eastern NE, slowly backing southwest. This feature will slow the progression of the surface cold front across the southwest quarter of the CWA through this morning, and then it should surge southward as 2-4mb/3hr pressure rises develop this afternoon.
A strong cold front will enter northwestern Oklahoma later this evening and pass quickly through central Oklahoma by sunrise Monday. This feature may give a period of light freezing rain near the Kansas border before the lift passes to the east. The main story will be the very wind and cooler conditions.
Today through Monday Nevada will be sandwiched in between ridging to the West and a longwave trof just to our northeast, which will bring a northwest flow to Nevada through the short term period. Some further cooling in the northwest flow will occur on Monday, especially in eastern Nevada as the longwave trof dips slightly further southwest, dropping highs in eastern counties into the 50's.
Cold front extends across the central Plains early this morning, and it will move into northeast Oklahoma after midnight. There may be a brief period of freezing rain across portions of Osage County early in the morning, but forecast soundings suggest enough cold air will quickly move in, which will likely result in a sleet/rain mix.
626 AM EST Sun Nov 10 2019 The center of high pressure will become elongated as it settles across the Carolinas through tonight.
246 AM MST Sun Nov 10 2019 A weak disturbance will track southeast across the area tonight, followed by a return of high pressure aloft early in the upcoming week.
Little moderation of the airmass Monday will mean high temps will struggle to reach the low teens with some locations seeing highs in the single digits. Now the highest temps will probably have to wait until Sat as 850 temps popping above 0C should translate to sfc readings above freezing to near 40.
901 AM EST Sun Nov 10 2019 High pressure will remain just north of the area through tonight.
Highs on track to reach into the mid to upper 70s north to the lower 80s south.
A short wave trough that is tracking through the PacNW is bringing high clouds to the area early this morning. High clouds move out by mid to late morning as high pressure builds back in. An anomalously cold trough will dig into the Central US late Sunday into Monday. High clouds will build back into the region on Monday as a trough approaches the PacNW.
542 AM CST Sun Nov 10 2019 Cold front as of 08Z has worked south of I 80 and colder air is starting to spill south across the region. With stratus deepening and lift within the stratus layer, there is the potential for freezing drizzle this morning but threat seems fairly low and have reduced pops a bit this morning. Radiational cooling will be maximized Monday night as ridge axis moves through the area promoting clear skies and light winds.
435 AM CST Sun Nov 10 2019 (Today and Tonight) Looks for warmer temperatures today across West Central Texas due to strengthening 850 mb thermal ridge and low level south to southwest flow. A strong cold front is still on track to move across the area on Monday.
849 AM EST Sun Nov 10 2019 High pressure will remain just north of the area through tonight.
437 AM MST Sun Nov 10 2019 09z surface analysis had cold front from western MT to eastern NE, slowly backing southwest. This feature will slow the progression of the surface cold front across the southwest quarter of the CWA through this morning, and then it should surge southward as 2-4mb/3hr pressure rises develop this afternoon.
bringing cooler temperatures and northerly winds to the area. Strong high pressure will settle across the area behind the departing system Monday.
Tonight starts out clear but then clouds begin to move into the area ahead of the next cold front.
342 AM CST Sun Nov 10 2019 Cold front as of 08Z has worked south of I 80 and colder air is starting to spill south across the region. With stratus deepening and lift within the stratus layer, there is the potential for freezing drizzle this morning but threat seems fairly low and have reduced pops a bit this morning. Radiational cooling will be maximized Monday night as ridge axis moves through the area promoting clear skies and light winds.
426 AM CST Sun Nov 10 2019 (Today and Tonight) Looks for warmer temperatures today across West Central Texas due to strengthening 850 mb thermal ridge and low level south to southwest flow. A strong cold front is still on track to move across the area on Monday.
The first cold front was sinking south into northern Kansas early this morning.
/issued 323 AM EST Sun Nov 10 2019/ Beautiful weather is in store today as high pressure settles across the Southeast in the wake of yesterday's cold front. Highs today are forecast in the low to mid 80s, but the apparent temperature will actually be a touch lower due to the low humidity and breezy conditions. Low temperatures tonight are forecast in the low 60s across the Lake region to the low 70s right along the East Coast under mostly clear skies.
The actual cold front (density gradient) will lag well behind the initial wind shift. As a result, overnight lows are expected to range from the lower to mid 30s. Upper ridge over the Great Basin to start the period will migrate to the southern plains by the end of the period.
