(Tonight) Another tranquil evening is in store across the Tennessee Valley as high pressure overhead will be the main influence on the local weather. Overnight some high clouds on the southern fringe of an upper level low across the Midwest will clip the area tonight. This should limit the radiational cooling, therefore not as cold tonight with temperatures only dropping down into the lower 30s.
1238 PM EST Mon Feb 19 2024 An upper low will move over the region Tuesday with a few clouds and expect temperatures slightly below normal.
Tuesday may end up being the warmest day of the seven day forecast as the upper ridge becomes centered overhead.
311 PM EST Mon Feb 19 2024 Low pressure will deepens well offshore Tuesday through mid- week as ridging persists inland.
923 PM EST Mon Feb 19 2024 High pressure and dry conditions will persist again tonight. Slightly cooler overnight lows are expected tonight, with readings falling to near freezing across much of the area. Tuesday night lows are forecast to be a few degrees warmer than tonight's.
550 PM CST Mon Feb 19 2024 A ridge of high pressure will bring dry and warmer temperatures to the Mid-South through mid-week.
As skies clear and cooler NW winds continue, temperatures will become chillier across South Florida with lows tonight in the mid to upper 40s for most areas. Exceptions will be east coast metro areas which fall into the low 50s and locations west of Lake Okeechobee which fall into the lower 40s. At the mid-levels, a cutoff low and the associated trough axis will soon exit the southeastern United States into the Atlantic as well. Temperatures tonight will fall into the lower to mid 40s inland over Southwest Florida and portions of the Everglades. The Naples area and the east coast metro should stay in the lower 50s.
Upper air analysis and water vapor satellite imagery this morning show a trough in the polar jet over New England, with a large ridge over the United States and Canada west of the Mississippi River, extending up to Alaska. The subtropical jet has a trough over the southeastern United States, ridging over the Desert Southwest extending up to Montana, and another pronounced trough off the West Coast with an embedded upper level low off the coast of northern California. Afternoon surface analysis places low pressure systems in north central North Dakota along the Canadian border, eastern South Dakota, central Kansas, and along the Rocky Mountains in Colorado. Western and north central Nebraska is under a high pressure center.
553 PM EST Mon Feb 19 2024 High pressure provides dry, mainly clear weather, with a warming trend, through mid-week. Similar to yesterday, the final few hours of daylight have promoted slightly warmer temperatures than previously anticipated, so adjusted up accordingly. Also opted to incorporate hi-res model guidance for sky conditions through the near term period, depicting occasional high cirrus passing over the area, then hugging the higher terrain during the day Tuesday. Widespread sub-freezing temperatures are anticipated again tonight as temperatures drop into the mid to lower 20s due to radiational cooling and cold air in place.
Parts of the Salt River, Wyoming, and Wind River Ranges will likely see the highest amounts ranging from 3 to 6 inches. Isolated amounts higher then 6 inches are possible over Pitchstone Plateau and the highest elevations of the Tetons. The highest snow amounts are expected in southern Lincoln County where the moisture feed persists longest.
547 PM CST Mon Feb 19 2024 - Quiet and warmer than normal weather to continue.
623 PM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
A strong upper low situated offshore of the Pacific Northwest advances towards the coast as the subtropical jet stream flows from the base of the trough and along the western periphery of the incoming ridge. The resulting mid-level height falls allow the lee-side trough to redevelop, and as the pressure gradient tightens, southerly winds begin increasing to 15-20 mph gusting to 30 mph around mid- to late-morning.
Tonight through Tuesday night A few high clouds around to move east northeast across the south associated with a weak upper level trough lifting northeastward from SD tonight through early Tuesday. Overall temperatures might be a few degrees cooler behind the trough axis for Tuesday highs especially in the central/north/northwestern portions of the forecast area.
Expect one more night of temperatures around the freezing mark most interior areas, with lows in the mid to upper 30s closer to the coast and lower 40s at the beaches. /22 (Tuesday night through Monday) Mid level ridging aloft and high pressure at the surface will keep conditions dry and warm through mid week.
856 PM EST Mon Feb 19 2024 Low pressure will deepens well offshore Tuesday through mid- week as ridging persists inland.
947 PM EST Mon Feb 19 2024 High pressure builds in through the middle of the week, maintaining sunny skies and dry conditions.
753 PM EST Mon Feb 19 2024 High pressure builds in from the NW tonight and will crest over the area Tuesday.
551 PM CST Mon Feb 19 2024 (Tonight) Another tranquil evening is in store across the Tennessee Valley as high pressure overhead will be the main influence on the local weather. Overnight some high clouds on the southern fringe of an upper level low across the Midwest will clip the area tonight. This should limit the radiational cooling, therefore not as cold tonight with temperatures only dropping down into the lower 30s.
541 PM EST Mon Feb 19 2024 Low pressure will deepens well offshore Tuesday through mid- week as ridging persists inland.
611 PM CST Mon Feb 19 2024 (Tonight through Tuesday night) An upper level ridge is moving into TX from the west with northwesterly flow over South Central Texas. A warmer, moister airmass is moving in. Temperatures are 10-15 degrees warmer than 24 hours ago and dewpoints are 15-20 degrees higher. The upper ridge axis will move from west TX to the east side of our CWA during this period. High pressure will continue to dominate in the low levels. Warm advection will mean low temperatures Tuesday morning will be around 10 degrees warmer than this morning. High temperatures will be around 10 degrees warmer than today in the 70s and lower 80s.
649 PM EST Mon Feb 19 2024 High pressure builds in through the middle of the week, maintaining sunny skies and dry conditions.
As the low that caused such a gloomy and rainy weekend has now propagated east, skies have cleared and temperatures have begun to cool. Northerly flow will primarily remain in place through midweek as high pressure continues to build across the FL peninsula, which will keep temperatures below climatological normal values over the coming days despite near full sunshine expected.
710 PM EST Mon Feb 19 2024 High pressure produces clear skies and light winds tonight resulting in widespread subfreezing temperatures. An upper low will move over the region on Tuesday with a few clouds and slightly below normal temperatures expected.
Above normal temperatures and dry weather will be present today, before a quick-moving trough swings through Arizona on Wednesday.
Guidance also continues to hint at a pronounced western trough and eastern ridge setting up at the end of the month, which could bring our next chance of active weather.
At the same time, a strong mid level ridge centered over Mexico will gradually extend eastward into the Gulf of Mexico heading into Wednesday. At the surface, high pressure centered off to the north will continue to bring mainly dry conditions to South Florida through Wednesday. This will keep high temperatures today and Wednesday in the upper 60s over the Lake Okeechobee region and in the lower 70s over the east coast metro areas. Tonight will be another chilly night as lows drop into the lower 40s across interior portions of Southwest Florida, and into the mid to upper 40s across the rest of the interior. The east coast metro areas will drop into the lower 50s.
307 AM EST Tue Feb 20 2024 Dry weather and a warming trend is expected through Wednesday with high pressure to our east.
In its wake was mid/upper level heights beginning to rise as an upper level ridge of high pressure expanded over the Southern Plains.
Of more consequence will be the significant warm-up expected across the area as broad upper ridging moves in from the W.
(Tuesday through Wednesday Night) High pressure shifts eastward on Tuesday putting the area on the western side of the anticyclone center. This results in WAA and and temperatures rebounding into the lower 60s. Overnight lows Tuesday night should remain above freezing dipping into the mid to upper 30s. By the middle of the week, ridging amplifies to our west and as it shifts to the east, southerly flow increases during the day Wednesday.
Ridging aloft will then assert itself over the CWA for the remainder of the short term, with dry conditions and mild temperatures anticipated.
351 AM EST Tue Feb 20 2024 High pressure remains centered over the region and this will continue to bring a period of quiet and mostly sunny weather through Wednesday.
(Today and tonight) High pressure with a dry airmass will continue across the area today. Overnight lows will generally range from the lower 30s in the coldest locations to the middle 40s along the panhandle coast.
The main challenge will be high temperatures, which were warmer than expected yesterday. Will go with an even warmer Wednesday, especially across the southern FA.
Another very quiet night across the region as an upper level ridge axis was beginning to push into western NE. The ridge will continue to make eastward progress today while at the surface, an area of low pressure will slide eastward along the NE/SD border, inducing strengthening southerly winds (20-25 mph gusts) which will usher warmer air into the area.
Temperatures were mostly in the lower to mid 30s. Far western sections were a little on the warmer side with mostly cloudy skies.
1238 AM EST Tue Feb 20 2024 High pressure brings dry and seasonal conditions through Wednesday. Milder temperatures are expected later in the week as high pressure moves offshore.
GAH AFTERNOON DISCUSSION: Ridge building over the Intermountain West will allow a warming trend to commence tomorrow.
908 PM CST Mon Feb 19 2024 The inherited grids remain in good shape as high pressure continues to create clear skies and calm conditions. Considering a relative accumulation of cooler surfaces / waters, there lies some signals for patchy fog late overnight into the early dawn hours. Otherwise, an upper level ridge of high pressure building north over Central America into the Great Plains will continue to progress Eastward slowly through the next couple days. Sfc ridging will build gradually into the eastern Gulf of Mexico through Wednesday night. Locally no precipitation impacts are expected through Wednesday afternoon while under a regime of high pressure.
349 AM EST Tue Feb 20 2024 Quiet weather continues over the next couple of days as high pressure moves overhead.
1145 PM CST Mon Feb 19 2024 The inherited grids remain in good shape as high pressure continues to create clear skies and calm conditions. Considering a relative accumulation of cooler surfaces / waters, there lies some signals for patchy fog late overnight into the early dawn hours. Otherwise, an upper level ridge of high pressure building north over Central America into the Great Plains will continue to progress Eastward slowly through the next couple days. Sfc ridging will build gradually into the eastern Gulf of Mexico through Wednesday night. Locally no precipitation impacts are expected through Wednesday afternoon while under a regime of high pressure.
1043 PM CST Mon Feb 19 2024 - Quiet and warmer than normal weather to continue.
Lows tonight will range from around freezing in the east, to the mid/upper 30s in the west. Because of this, nighttime temperatures will cool into the upper 30s with a few areas east of I- 55 reaching near freezing. Afternoon model guidance continues to highlight a upper-level ridge over the central CONUS beginning on Wednesday. Afternoon temperatures will reach seasonal normal as the ridge pattern amplifies to our west.
1225 AM EST Tue Feb 20 2024 High pressure will bring a period of quiet and mostly sunny weather through Wednesday.
322 AM EST Tue Feb 20 2024 High pressure will bring a period of quiet and mostly sunny weather through Wednesday.
235 AM EST Tue Feb 20 2024 Dry high pressure will remain over the western Carolinas and northeast Georgia today through Wednesday.
High pressure and dry conditions will persist again tonight. Slightly cooler overnight lows are expected tonight, with readings falling to near freezing across much of the area. Tuesday night lows are forecast to be a few degrees warmer than tonight's.
A low impact weather system will bring gusty southwest winds, cooler temperatures, and chances for light rain and snow showers from late Tuesday through Wednesday. Mid and high level clouds are covering Arizona this evening as a trough impacts the west coast. Still expecting it to take some time for this trough to actually cross Arizona, late Tuesday into Wednesday. On Tuesday, expect increasing southwest wind speeds and thickening mid and high level clouds in response to an approaching Pacific trough. On Wednesday, the Pacific Trough is forecast to sweep across the area bringing chances for rain and high elevation snow.
/Issued 1235 AM CST Tue Feb 20 2024/ /Tuesday and Wednesday/ Mid-level ridging will dominate the weather pattern for the next couple days. This morning will start cool with temperatures in the low to mid 40s. Much warmer air from the High Plains to our west has been transported over the region overnight, which will help nudge temperatures well above- normal today. Highs are forecast to peak in the low 80s west of I-35/35W this afternoon (70s further east), about 15-20 degrees above normal. Parts of the Big Country even have a 35-45% chance of peaking in the low 90s.
Currently - The axis of a upper level trough is now pivoting into the Atlantic. This is also maintaining cool, dry, and stable post cold frontal conditions. Temperatures are broadly in the lower 60s with dew points broadly in the upper 50s. The combination of a ridge stretching southwestward into the Gulf of Mexico and troughing off the Atlantic coast will maintain gentle to moderate northwest to northerly breezes on Keys waters through the overnight period.
Temperatures are currently in the upper 30s to middle 40s with morning lows expected to fall into the low to middle 30s. After tonight, additional freezing temperatures do not look likely over the next 7 days.
Expect one more night of temperatures around the freezing mark most interior areas, with lows in the mid to upper 30s closer to the coast and lower 40s at the beaches.
1047 PM CST Mon Feb 19 2024 (Tonight through Tuesday night) An upper level ridge is moving into TX from the west with northwesterly flow over South Central Texas. A warmer, moister airmass is moving in. Temperatures are 10-15 degrees warmer than 24 hours ago and dewpoints are 15-20 degrees higher. The upper ridge axis will move from west TX to the east side of our CWA during this period. High pressure will continue to dominate in the low levels. Warm advection will mean low temperatures Tuesday morning will be around 10 degrees warmer than this morning. High temperatures will be around 10 degrees warmer than today in the 70s and lower 80s.
Scattered light rain and snow showers, mainly in eastern Oregon, tonight through Wednesday, with a trough of low pressure holding along the coast. Drier later this week when the trough is forecast to weaken.
324 AM EST Tue Feb 20 2024 High pressure will promote dry and seasonable conditions through Wednesday.
1042 PM CST Mon Feb 19 2024 - Warming trend continues through Wednesday with near record highs in the low 70s.
Another night of high pressure and light winds will lead to cold temperatures once again. At the surface, a high pressure ridge over the area today will shift east of the Appalachians. The main impact of this trough will be to increase high and midlevel clouds during the day, mainly across the southern half.
Parts of the Salt River, Wyoming, and Wind River Ranges will likely see the highest amounts ranging from 3 to 6 inches. Isolated amounts higher then 6 inches are possible over Pitchstone Plateau and the highest elevations of the Tetons. The highest snow amounts are expected in southern Lincoln County where the moisture feed persists longest. The end of the week finds the active pattern settling down as ridging develops and gradually moves into the area. Daytime highs in Natrona and Johnson Counties climb into the lower to mid 40s for the first half of the week. Mild temperatures and dry conditions continue through the end of the week, with many other locations seeing highs reach the lower to mid 40s by the weekend given the ridging over the western CONUS.
Aloft in our subtropical westerlies, a ridge will be building enhancing our warming trend with mild yet above average high temperatures in the 70s across Oklahoma to near 80 degrees south of the Red River across western north Texas. Our upper ridge will be dirtying up with thin high Cirrus increasing, so not expecting them to strongly affect peak heating. South winds will persist through tonight although not breezy, but will see temperatures tonight warmer than this morning and only falling into the 40s.
With abundance of sunshine this afternoon, the highs will top out from the mid to upper 70s into the low to mid 80s across the region. This promotes a warmer and more humid night as result of the stronger moisture and warm air advection coming off the Gulf. Latest guidance, especially the short term members, indicate that the low stratus could stay rather pesky and linger through early Wednesday afternoon.
Thus, another quiet night here as much of the activity remains across the West with a low pressure system. As this system eventually weakens upper level ridging is forecast to build across the Great Plains through mid-week. Medium/long range guidance seems to be in fairly good agreement from here with an upper level trough moving over southeast Canada to end the week/start the weekend. However, the question continues to remain around if there will be enough moisture to work with as model soundings show quite a bit of dry air in the lower levels.
(Tuesday through Wednesday) The return of southerly winds will make for a warmer start this morning, as freezing temps are only expected across portions of SE Oklahoma and adjacent SW Arkansas. Expect quiet conditions to remain today, as upper ridging will build into the region. With sunny skies and southerly winds, most of the region will warm into the low to mid 70s this afternoon. Warmer conditions will continue tonight, with lows ranging from the upper 40s to lower 50s. Other than some morning low clouds, quiet conditions will continue on Wednesday, as upper ridging will remain over the region.
1036 PM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
Upper trough moves across the region this morning with some high clouds. Discussion: An upper level trough currently across western Kentucky will move quickly across the region this morning and through the afternoon. This will bring some high clouds to the region this morning and into the early afternoon hours, but precipitation is not expected as dry air remains throughout the low-levels.
101 AM EST Tue Feb 20 2024 High pressure produces clear skies and light winds tonight resulting in widespread subfreezing temperatures. An upper low will move over the region on Tuesday with a few clouds and slightly below normal temperatures expected.
Mid/upper level high pressure will continue to dominate S TX weather through mid week keeping rain out of the forecast. Low level southerly flow will continue to usher a warmer airmass into S TX leading to above normal temperatures. Lows tonight will also be warmer ranging from the mid 50s to around 60. A light to moderate southerly wind is expected today, becoming a bit more breezy Wednesday due to deepening low pressure across W TX and the Southern Plains.
522 AM EST Tue Feb 20 2024 Dry weather and a warming trend is expected through Wednesday with high pressure to our east.
Temperatures are dropping through upper 50s and the lower 60s, with dewpoints in the mid 50s, and winds on land from the north around 10 mph.
613 AM EST Tue Feb 20 2024 High pressure remains centered over the region and this will continue to bring a period of quiet and mostly sunny weather through Wednesday.
534 AM CST Tue Feb 20 2024 - Warming trend continues through Wednesday with near record highs in the low 70s.
214 AM MST Tue Feb 20 2024 Warm front moves through NE Montana this morning which will allow for warmer temperatures today. There will be some mid and high level clouds this morning which will clear from SW to NE today as the warm front moves to the NE. A weak cold front is expected on Wednesday which will lower temperatures a few degrees mainly in the north. An upper ridge builds over the western US the next few days which keep temperatures above normal with mainly dry weather the remainder of the week.
The warming trend will continue today with highs ranging from the 60s at the beaches, mid to upper 70s near the coast and the lower 80s elsewhere. The warmer temps will be a few degrees above normal. Wednesday will be warmer with highs generally in the low to mid 80s, except for the 70s near the coast.
404 AM EST Tue Feb 20 2024 (Today through Wednesday) An axis of a mid-level ridge is centered over Georgia as the morning begins. Considering the near freezing temperatures and light winds, some areas of frost will be possible in the early morning hours. The warming trend in temperatures will continue this afternoon, with highs expected to climb into the low to mid 60s. Ran on the low side of dewpoints considering the likely mixing down of dry air aloft, favoring drier hi-res guidance and NBM 10th percentile. Southeasterly to southerly low-level flow will begin to set up on Wednesday as high pressure strengthens to the east of the area, which will promote the advection of warm and moist air into Georgia. The influence of the high will lead to another day with benign weather conditions.
A building mid/upper ridge over SW CONUS will push over TX today through tomorrow. Southerly winds increase on Wednesday as the gradient steepens between high pressure over eastern CONUS and lowering pressure over the plains. Temps at the beaches are expected to be about 5 to 7 degrees cooler than inland areas.
Upper level ridging will be dominant over the region today, with a more zonal flow pattern setting up tonight and Wednesday. At the surface, weak high pressure will be over the area today and tonight. A fairly weak low pressure system and an associated frontal boundary will track across the region on Wednesday, doing little more than creating a directional wind shift. Through the course of the extended we go from a ridge to the south and trough to the northeast with strong zonal flow aloft, to a stronger eastern CONUS upper trough with northwest flow aloft.
An upper ridge extended from western Mexico northward through the Rockies. At the surface, high pressure extended from New England to the Louisiana coast. The NBM guidance favors the warmer globals and won't adjust those.
no major, organized, widespread impacts are expected, but very localized patches of fog could become quite dense and dangerous for motorists each morning, and precip showers that fall when and where temps are just cold enough for snow could lightly coat a highway or two at times (or set some areas up for patchy ice as temps cool at night), and we're even seeing hints that some light drizzle or freezing drizzle could be falling along portions of I-84 south of Idahome early this AM.
841 AM EST Tue Feb 20 2024 Dry weather and a warming trend is expected through Wednesday with high pressure to our east.
929 AM EST Tue Feb 20 2024 High pressure remains centered over the region and this will continue to bring a period of quiet and mostly sunny weather through Wednesday.
