High temperatures will range from the lower 30s to lower 40s. Several short wave troughs will be working across the region in a longer wave trough axis. If precipitation does occur, there would be concerns whether ice would be present suggesting maybe some freezing drizzle. Better chances for light precipitation look to be more into Wednesday when some isentropic up glide on the 285K surface catches up with the short wave trough.
A series of dry cold fronts will move through the region with persistent northwest flow aloft this week.
A long wave positively tilted trough with an axis that extends from southeast Texas towards the Mid-Atlantic states is expected to progress eastward through the region today.
A dry cold front has moved across the Tennessee Valley this afternoon. Near seasonable highs will come on Tuesday, as high pressure continues to nudge east. Overnight lows look to be near the freezing mark, with the greatest chances for sub-freezing temperatures over northeast AL. Westerly flow will remain aloft through the end of the work week, and high pressure will build over the Gulf Coast region.
An associated weak/diffuse cold front continues to move through, with the only noticeable impact being an increase in dew points.
226 AM EST Tue Feb 8 2022 Low pressure moves along our coast today and tonight. High pressure builds back over the area from the west late Tuesday through late week.
109 AM EST Tue Feb 8 2022 Light snow is possible early this morning along the I 80 corridor and in the ridges.
950 PM CST Mon Feb 7 2022 Another night with cooler than normal temperatures is on the way to the Ark-La-Tex. That said, temperature grid adjustments were made to account for slightly warmer temperature trends, especially in western zones. /issued 530 PM CST Mon Feb 7 2022/ For the 08/00Z TAF update, VFR conditions will prevail through the period under high pressure entering from the west.
Low-level ridging builds back in tomorrow with a dry airmass and a mostly clear sky. Minimal cloud cover and VFR prevailing conditions are forecast throughout the TAF period with light winds as high pressure builds in from the west. Upper level trough swings across the area tonight into tomorrow morning.
As a result of the timing of the front and some snow cover, areas in our NW only reached around 30 degrees, while areas in our east were able to briefly warm to the low and mid 40s. A few spots around 50 are expected in the typical warmer locations. Wednesday will feature temps comfortably in the 50s for most, thanks to deep southwesterly flow ahead of an approaching cold front. This cold front looks to pass through the region by Wednesday afternoon or evening, and appears to be mostly dry.
1040 PM EST Mon Feb 7 2022 A cold front will push southeast across Pennsylvania overnight, then high pressure will build in from the Ohio Valley on Tuesday.
closer to 8 knots) as high pressure settles into the area. Behind the passage of last night's cold frontal boundary, moderate north winds have allowed drier air to filter into SE TX. This will have the further effect of allowing for more efficient radiative cooling overnight, and as a result have opted to side with the lower end of guidance for overnight lows. Most inland locations will remain in the low to mid 30s, while coastal locations settle in the lower 40s and the far northern zones may once again reach the upper 20s. With the loss of any CAA from today's northerly flow, highs of a few degrees warmer than today should result with most locations breaking into the mid 60s.
A dry cold front will move through the area late tonight and downsloping winds will help boost highs tomorrow into the 50s and be near 60 degrees across south central Nebraska. There isn't much moisture for this system to work with and forcing is not particularly robust so expect any accumulations will be light, ranging from around half an inch or so up near the Pine Ridge to a dusting south of Interstate 80.
A dry cold front will move into the north by the end of the period.
1225 AM EST Tue Feb 8 2022 An approaching cold front will bring deteriorating weather conditions to the terminals during the next 24 hours as rain and lowering Cigs/Vsbys move into the region with widespread prevailing MVFR/IFR conditions developing after 09Z with intermittent LIFR possible. This is as an approaching trough of low pressure and associated cold front continue to move east, pushing more moisture and supporting stratiform rain tonight and on Tuesday. By Tuesday afternoon though, most of the area is expected to have an 8 to 10 degrees decrease for the high. This combined with the light rain and ample cloud coverage will make it feel cooler, especially in the afternoon when winds are expected to pick up.
1027 PM MST Mon Feb 7 2022 02z surface analysis had cold front from northeast MT into central ID. First batch should occur with cold front, focused on squeeze area just east of the Black Hills. Surface map shows a trough over the northern plains, with a warm front along its axis across the eastern Dakotas. The first wave will approach tonight, and the cold front will begin crossing our CWA early Tuesday morning. With the Froude number expected to stay between 1-2 for nearly 24 hrs, going along with the trend of increasing snow amounts: generally 3-5 inches in the northern BH, with around 6 inches possible in the highest elevations.
A cold front will begin to make its way through the region around 23-00Z on Tuesday afternoon shifting breezy westerly winds to the north. A little more in the way of wind is expected Tuesday with periodically breezy west-southwest winds developing ahead of a cold front. That cold front will enter the northwestern part of the forecast area mid-afternoon and advance to near a Childress to Lubbock to Hobbs line by 00Z Wednesday. The warming trend will continue Tuesday with the increased downslope component and a dry air mass ahead of the cold front in line with MOS numbers. Upper ridging across the western CONUS and longwave troughing across the eastern CONUS will remain in place through much of the forecast period.
1240 AM EST Tue Feb 8 2022 Low pressure moves along our coast today and tonight. High pressure builds back over the area from the west late Tuesday through late week.
Milder temperatures are likely again today with only slightly cooler air spreading into western Kansas in wake of the frontal passage, dropping H85 temperatures having ascended to around 10C ahead of the front back down into the mid single digits(C). Look for highs generally back up into the 50s(F) this afternoon with the lower 60s(F) expected in south central Kansas.
1130 PM CST Mon Feb 7 2022 Summary: Warmer weather on Tuesday with some mixed precipitation chances.
333 AM EST Tue Feb 8 2022 Inbetween systems today, low clouds with areas of fog and drizzle are likely until an upper trough swings through this evening changing any precipitation to isolated snow showers, mainly across the higher terrain.
1017 PM CST Mon Feb 7 2022 (This evening through Tuesday) As expected, cold front has limited afternoon temperatures a little with readings mainly in the mid 50s. Lows will drop into the 20s for most areas, Returning southerly winds by sunrise will keep some of the higher elevations across the Big Country up a few degrees higher than other locations.
1236 AM EST Tue Feb 8 2022 Weak low pressure will continue to lift northeast towards the Gulf of Maine. High pressure then builds into the region for most of the week. A cold front passes through late in the work week, and then a stronger cold front passes through over the weekend. Lows tonight will range from the mid 20s north to around freezing along the coast and far southern Delaware. The main feature through the short term will be the high building over the region then shifting further east.
Some locations will climb above freezing tonight and temperatures in the mid 30s everywhere are a good bet during the day Wednesday.
/issued 856 PM CST Mon Feb 7 2022/ High pressure is beginning to settle over the Mid-South this evening behind a weak cold front that moved through earlier today. As a result temperatures are in the low 40s, but still well above freezing. Dry conditions and mostly above freezing temperatures are expected for the remainder of this week into the weekend. A ridge will continue to build over the Mississippi Valley Wednesday resulting in highs in the 60s across the Midsouth.
Upper air analysis last evening showed a trough axis along the Texas coast with northwesterly flow over the state. This will bring warmer air to the area. High temperatures today will be around five degrees warmer than yesterday. Winds will shift to southerly tonight and low temperatures will be similarly warmer.
949 PM MST Mon Feb 7 2022 Ridging along the Pacific Coast is deflecting the storm track well to the north and east. The northwest flow aloft will continue as ridging across the western US keeps most of the systems to our east.
Lows will be a little warmer tonight than last night as winds come around out of the southwest.
SW winds increase with gusts to near 20-25kts between 18Z-21Z/Tue ahead of a cold front Tue evening. (This afternoon through Tuesday night) An upper trough moved into the region overnight and is passing SE out of the area today. While this is happening a ridge sits over the West Coast. The ridge will begin to build into the area Tuesday but another trough swinging down across the Northern Plains will limit the high pressure. should end up a few degrees cooler than yesterday.
302 AM EST Tue Feb 8 2022 Dry weather is expected today as high pressure builds to the south.
A positive-tilt trough axis sits over South TX today with meridional flow aloft over the Southern Plains bringing another brief round of cold and dry air advection for this evening. The low level CAA winds for tonight should ease up by 09Z, which should allow for some good radiational cooling in valleys, especially for the eastern Hill Country and parts of Central TX. After daybreak, when the winds become W/SW across all of the forecast area, the warming trend should accelerate, with maxes a good 5 degrees or more warmer than those for today. A warmer start to the evening Tuesday should lead to a subtle warming trend on min temps for Wednesday morning, even though dew point values will remain plenty dry for efficient cooling under a mostly clear sky.
1230 AM EST Tue Feb 8 2022 A weak cold front will push through the area bringing clouds and a few flurries north of I-70. Dry weather expected through Wednesday as high pressure builds into the region.
923 PM PST Mon Feb 7 2022 High pressure will rebound Tuesday bringing a prolonged period of mild and dry weather with areas of morning low clouds and fog. High pressure to strengthen over the region and keep potential for fog and low clouds over portions of the inland northwest primarily during the overnight and morning hours.
Issued by National Weather Service Jackson KY 953 AM EST Tue Feb 8 2022 Dry weather is expected today as high pressure builds to the south.
This was evident by the predawn temps that ranged fm the mid 20s to the lower 30s, with lower 40s noted in some of the higher elevations. Not much chg to the going fcst as a broad upper lvl trof wl persist thru Wed, resulting in a NW flow ovr the Mid-South. We wl cont to see the parade of mid lvl trofs with the next one set to pass acrs AR later tngt into Wed, along with an assocd fntl bndry.
Ridge of high pressure anchored over the West Coast will keep conditions dry and warm across much of the region this week, with periodic northerly breezes. Ridging over the west coast will be the dominant feature through the end of the week and into the weekend. This ridging will allow for temperatures to warm up to well above normal for this time of year.
Wednesday offers to be on the mild side too as another weak and and moisture starved cold front moves through the region.
/AJ/ Today and Tonight: A weak midlevel trough with an axis centered over the ArkLaMiss region will continue cool and dry conditions throughout the remainder of the short term period. By this evening, the trough axis should remain east of MS, which will allow for sustained light W/SW winds into the overnight period. Low temperatures will bottom out in the lower to mid 30s overnight. Broad mid-level troughing will remain present across the region.
This system and associated cold front will sweep east away from the area by mid to late afternoon. High temperatures are expected to be between 4 and 8 degrees cooler in wake of this Pacific cold front. Despite highs in the 40s in the lower elevations on Wednesday; showers that are strong enough to precipitate should be snow pellets and/or snow as the dry air cools to the wet-bulb temperature which will be below freezing. Northwest flow will dominate the pattern as the ridge remains across the western CONUS.
High pressure aloft situated off the west coast will result in mostly clear skies and warmer than normal temperatures through the weekend.
641 AM EST Tue Feb 8 2022 Dry weather is expected today as high pressure builds to the south.
A more zonal mid to upper flow pattern will generally return across the region later tonight into Wednesday along the base of a larger trough encompassing much of the eastern CONUS. Highs Wednesday should warm into the lower to mid 60s inland and around 60 degrees near the immediate coast and beaches.
Very strong low-level warm air advection will occur ahead of the next in a series of cold fronts. The cold front is expected to pass through the CWA tonight, but little impact is expected other than an uptick in mid/high level cloudiness and a wind shift to the northwest. Gosselin A secondary cold front is forecast to move through Wednesday night. Similar to its predecessor, the only real impacts to the bi-state area will be an increase in mid/high level cloudiness and slightly cooler temperatures after its passage.
An associated cold front today will introduce wind gusts to perhaps 40 mph directly behind the front, considering pressure rises of near 4 mb/3 hours. Went just a couple of degrees warmer with highs today considering strong mixing and clearing by mid to afternoon.
Afternoon temperatures today will range from the lower to mid 60s across the region with plentiful sunshine. Temperatures will remain above freezing tonight, also the first time for the past few days.
Patchy freezing fog across the Susquehanna Valley should gradually dissipate through daybreak as northwest breeze picks up behind sfc cold front. Mainly clear to partly cloudy skies tonight as high pressure ridge axis moves across the CWA.
IR satellite trends suggest the low clouds may have reached the eastern extent/Susquehanna River. We will let the SPS for black ice/freezing fog expire at 13Z. Previous Discussion Issued: 425 AM EST Tue Feb 8 2022 Patchy freezing fog across the Susquehanna Valley should gradually dissipate through daybreak as northwest breeze picks up behind sfc cold front. Mainly clear to partly cloudy skies tonight as high pressure ridge axis moves across the CWA.
Temperatures are expected to be cooler for most places today and this should keep humidities a little higher. High temperatures will be in the 50s over south central zones and cooler in the southeast with 40s.
Sufficient moisture flux in the boundary layer combined with weak trough-supported ascent will support some light snow and flurries. Clouds will clear overnight with brief ridging and dry advection. Warm advection will drive high temperatures a few degrees above avg on Wednesday, but the approach and passage of another trough will promote light rain and snow for Wednesday.
However, a nice warm up will be in store for the area after sunrise as winds veer to a southwesterly direction in response to high pressure becoming centered just east of the region. The clear sky and dry air mass in place will allow for good radiational cooling this evening, with temperatures eventually settling in the lower 30s by early Wednesday morning.
Warm and dry weather will continue this week under high pressure.
With the lack of a stronger cold front, wind speeds will likely wait to increase more substantially until diurnal processes mix out the boundary layer this morning. Cooler temperatures are expected Wednesday as the baroclinic zone stalls to the west.
Upper ridge off the Pacific Coast will keep the area under NW flow aloft.
At the larger scale, 500mb upper ridge firmly in control of the Pacific NW and west coast helping keep the upper trough anchored over the eastern half of the conus. with pieces of energy dropping in to reinforce the trough.
637 AM EST Tue Feb 8 2022 Low pressure moves along our coast today and tonight. High pressure builds back over the area from the west late Tuesday through late week. The area of low pressure that brought us rainy weather yesterday is now well to our northeast and will continue moving farther away from the area this morning. Between 9 AM and noon, a dry cold front now just northwest of Raleigh, will help break up the inversion and our skies will brighten quite a bit as the low clouds scour out. High pressure builds across Eastern North Carolina tonight.
A warming trend will continue through mid to late week as high pressure strengthens over the region with periods of dry offshore winds. The windiest areas will be the highest peaks of the North and East Bay.
However, the lower RH in the south does not overlap with the stronger wind speeds in the north. At the surface, a lee low/trough will develop this afternoon with high pressure building in over the Central Plains. Guerrero An upper level ridge of high pressure will be found along the west coast and western parts of the U. Meanwhile, an upper level trough will be found across the eastern 1/3rd of the U.
Lows tonight will drop to around freezing. locally higher amounts across the highest elevations.
231 AM PST Tue Feb 8 2022 Dry and mild conditions will continue through the weekend as high pressure remains over the region. Ridge of high pressure continues to remain firmly in place over 40N and 135W in the northeast Pacific.
High pressure building into the Lone Star State will produce VFR conditions at the aerodromes through the next 24 hours.
302 AM PST Tue Feb 8 2022 High pressure will rebound Tuesday bringing a prolonged period of mild and dry weather with areas of morning low clouds and fog. Tuesday and Wednesday: Quiet weather is expected over the next several days as a strong ridge of high pressure moves inland with a northwest flow aloft. Current satellite imagery shows high level clouds moving into the Inland Northwest as systems pass over the ridge into British Columbia. The warmer temperatures and breezy winds from today have kept fog almost nonexistent across the northern and central valleys. Temperatures today will be cooler compared to yesterday with highs in the upper 30s to mid 40s (low 50s in the L-C Valley today and tomorrow). The region will see slight warming on Wednesday with highs in the low to upper 40s.
Winds will be the primary concern today as a cold front moves through the forecast area. That deep mixing will should mix warmer temperatures down to the surface and allow for efficient momentum transfer.
SW winds increase with gusts to near 20-25kts between 18Z-21Z/Tue ahead of a cold front Tue evening. A little more in the way of wind is expected Tuesday with periodically breezy west-southwest winds developing ahead of a cold front. That cold front will enter the northwestern part of the forecast area mid-afternoon and advance to near a Childress to Lubbock to Hobbs line by 00Z Wednesday. The warming trend will continue Tuesday with the increased downslope component and a dry air mass ahead of the cold front in line with MOS numbers.

322 AM CST Tue Feb 8 2022 Today and Tonight: A weak midlevel trough with an axis centered over the ArkLaMiss region will continue cool and dry conditions throughout the remainder of the short term period. By this evening, the trough axis should remain east of MS, which will allow for sustained light W/SW winds into the overnight period. Low temperatures will bottom out in the lower to mid 30s overnight. Broad mid-level troughing will remain present across the region.
655 AM EST Tue Feb 8 2022 A cold front is expected to move through the area today bringing deteriorating weather conditions to the terminals through the period. /issued 329 AM EST Tue Feb 8 2022/ An upper level trough will dig across the Southeastern States and northern Gulf coast today with an attendant cold front moving south through the forecast area through tonight. The rain will gradually end from north to south on Wednesday morning as the upper trough and front moves to the east of the area. Dry weather will return Wednesday night and continue through the end of the week as high pressure builds in from the west.
Sufficient moisture flux in the boundary layer combined with trough-supported ascent will support some light snow and flurries. Clouds will clear overnight with brief ridging and dry advection. Warm advection will drive high temperatures a few degrees above avg on Wednesday, but the approach and passage of another trough will promote light rain and snow for Wednesday.
541 AM CST Tue Feb 8 2022 High pressure will dominate over the region keeping skies mainly clear during the upcoming TAF period. Upper air analysis last evening showed a trough axis along the Texas coast with northwesterly flow over the state. This will bring warmer air to the area. High temperatures today will be around five degrees warmer than yesterday. Winds will shift to southerly tonight and low temperatures will be similarly warmer.
A high pressure system will hang out in the Northeast Pacific throughout this coming week, affecting the coast of Northwest California. However, due to increasing subsidence and offshore flow, there will be drying of the lower levels of the atmosphere along with adiabatic warming. This will set up a situation where there will most likely be warmer than average high temperatures for the middle of the week. High temperatures could reach the low 70s at the coast and potentially low 80s in the interior valleys. This will promote stronger winds and gusts at the higher ridgetops. GFS was showing a low pressure system making it down to the region, but when referring back to the GFS, it no longer showed a low pressure system making it to the area.
This moisture plume is associated with a positively-tilted trough penetrating the Gulf Coast states. The aforementioned trough will pivot eastward. However, owed to decaying wave energetics, the trough will deamplify as it approaches the Florida Peninsula. Forecast soundings do indicate a pretty moist-enriched environment for tonight and Wednesday, and given the proximity of the trough, scattered to widespread bouts of stratiform precipitation are possible for these periods. As a weak area of high pressure builds over the Gulf of Mexico, northerly breezes will freshen for the rest of the weak, with lowering rain chances.
High pressure over the Pacific will continue to push to the east over the coming week, keeping us on the east side of the mid level ridge.
Latest visible satellite imagery and surface observations are showing overcast skies around 5 kft and cool temperatures in the low to mid 50's. A cold front is expected to move through the area today bringing deteriorating weather conditions to the terminals through the period. Light to moderate rain expected over the eastern gulf waters through the day as a cold front moves through the area.
