At the sfc, a cold front will quickly progress eastward away from the state. Behind the front, sfc ridging will move into the state from the NW. This will provide the lighter winds and clear sky conditions along with cooler temperatures. Sfc ridging will remain centered just north of the state through the end of the period.
As yesterday's upper level system continues to depart the region, high pressure fills in behind it with easing pressure gradients. likely remaining in the low to mid 50s.
Otherwise, overnight lows will be 5 to 10 degrees warmer, ranging from the upper 20s northwest into the mid 30s for our eastern counties.
317 PM CDT Tue Mar 26 2024 - Widespread sub-freezing temperatures tonight with most locations in the teens and 20s.
A broad mid-level troughing pattern is in place across the CONUS today as yesterday's storm system now moves into southern Ontario. With clear skies and light winds, temperatures tonight will drop well below freezing area-wide, cooling into the low 20s and teens. High pressure slides southward tomorrow and southerly winds return as upper level ridging approaches the region. This will result in a warming trend that will continue through the end of the workweek, with each subsequent day being a good ten degrees warmer than the previous day.
336 PM EDT Tue Mar 26 2024 Mild air streaming northwards ahead of a slow moving cold front will maintain above normal temperatures through at least Wednesday.
224 PM EDT Tue Mar 26 2024 Dry high pressure continues with more seasonable temperatures for today.
216 PM CDT Tue Mar 26 2024 - Warmer weather is expected the remainder of this week as an upper level ridge of high pressure builds eastward from the Rockies.
(Rest of today through Wednesday) Mid-level ridging remains entrenched across our region this morning with southeasterly winds in place across the area as we remain in the warm sector of an approaching frontal boundary that is propagating across the northern Gulf of Mexico. High temperatures will range in the low to mid 80s across the majority of the area with a few locales across southwestern Florida reaching the upper 80s.
- Much cooler air returns tonight through Wednesday night, which could lead to a flash freeze scenario after a couple days of liquid precipitation. - Temperatures warm back into the 40s and 50s for highs later this week, with increased rain/snow/freezing drizzle chances over the weekend.
1221 PM CDT Tue Mar 26 2024 (Today through Wednesday afternoon) Current surface observations show the weak cold front has nosed into the Permian Basin, bringing light northeasterly winds and a notable chill in the air. Temperatures behind the front have fallen into the 40s and 30s with even below freezing temps at Tatum. The worst of the winds are behind us now that the large upper trough has positioned itself overhead with its base and associated speed max nudged all the way down into Mexico. With this, have extended the High Wind Warning for the Guadalupe zones through 01z. Temperatures this afternoon remain on the cool side due to the lowered thickness with the trough overhead and added cloud cover.
(Now through Wednesday) A cold front has completed moving through the forecast area and exited to the east, and showers currently located mainly east of I-65 taper off leaving dry conditions later this afternoon. A large upper trof spanning much of the CONUS amplifies a bit while progressing slowly to over the central and eastern CONUS through Wednesday. The cold front which exited to the east of the area meanwhile looks to become nearly stationary over the far northeast Gulf into Georgia. Lows tonight range from the mid 40s well inland to the lower/mid 50s near the coast. Highs on Wednesday will be in the lower to mid 70s.
Disorganized short wave trough moving through our CWA this morning with scattered showers mainly in the Owyhee mountains.
The wild card for today is how warm will afternoon highs get, the rain and cloud cover has kept things cooler but once we see some clearing things should warm up quickly. Highs should reach the upper 60s to low 70s except on the Plateau where it will stay cooler. We will remain in a troughing pattern on Wednesday and with the cold front off to our east it will be much cooler. Strong upper level ridge will be building over the central part of the country with high pressure over our region.
/29 (Now through Wednesday) A cold front has completed moving through the forecast area and exited to the east, and showers currently located mainly east of I-65 taper off leaving dry conditions later this afternoon. A large upper trof spanning much of the CONUS amplifies a bit while progressing slowly to over the central and eastern CONUS through Wednesday. The cold front which exited to the east of the area meanwhile looks to become nearly stationary over the far northeast Gulf into Georgia. Lows tonight range from the mid 40s well inland to the lower/mid 50s near the coast. Highs on Wednesday will be in the lower to mid 70s.
A narrow high pressure appendage stretches southeast from the Carolinas to east of the Bahamas. A cold front bisecting the Florida Panhandle extends to a broad low pressure center in the Bay of Campeche. The gradient between the high and low pressure systems supports southeast winds at the Reef, with averages 14 to 17 knots. Temperatures along the island chain are in the mid 80s and dewpoints are in the lower 70s. The approach of the cold front Wednesday night will be accompanied by an organized veering profile with much improved low level moisture.
with upper ridging extending northward through the western Atlantic and broad upper troughing extending southward through the central U. On the surface, high pressure east of Florida ridging across the area keep us in a warm air mass with rain- free conditions for today and tonight. Farther to our north and west, an area of low pressure moves through the Great Lakes region with an extensive cold front extending southward through the Mississippi River Valley to MS/AL.
Aloft, an upper ridge is already starting to build over the region and hi-res CAMs shut off the precip around midnight. Things should be dry for most of the day Wednesday but precip chances begin to rise late Wednesday in the central mountains as the aforementioned ridge quickly gives way to another U/L trough sinking into the Pacific NW. Temperatures tomorrow should warm into the upper 40s and lower 50s in the Magic Valley and Snake Plain with upper 30s to mid 40s likely across the high country.
- Quiet conditions prevail Wednesday, though afternoon highs will be 15 to 25 degrees below normal in the lower 20s to mid 30s.
Convection/narrow cold frontal rain band feature clears the area to the east by 7 PM then the colder air rushes in in behind the cold front. Lows dipping down to near freezing tonight. - Dry/Cool to End The Workweek Low strato-cu clouds lingering much of Wednesday due to cold cyclonic flow but some clearing arriving by late in the day as sfc ridging starts to nudge in.
(This evening through Wednesday) Many locations dipped below freezing this morning, with the West Texas Mesonet at Sterling City bottoming out at 26 degrees! This afternoon has remained in the cool side despite the abundant sunshine. Temperatures as of the 2 PM hour are in the lower to mid 50s in the Big Country and the the mid 50s to mid 60s across the remainder of the area. For Wednesday expect more sunshine and warmer temperatures, with highs warming into the upper upper 60s to mid 70s. High res model guidance shows a few storms across our far eastern counties- with the higher coverage over portions of north and central Texas.
(Through tonight ) At mid afternoon a mid level trof axis was exiting Northeast Oklahoma. light winds will help temps fall below freezing across the northern half of the CWA with mid 30s common across the southern half. there remains a slight chance of light rain developing with the mid/upper level low across parts of Eastern Oklahoma during day. Any activity development north of the Red River should weaken by Wednesday evening as the mid/upper level trof axis moves through and exits the region. Cloud cover should also taper off and exit from west to east Wednesday night with another cool night for parts of Northeast Oklahoma and far Northwest Arkansas reaching down to near freezing.
As the parent low pressure system pivots northeastward out of Wisconsin into Ontario, winds will become westerly and gusts will diminish. Expect low temperatures in the lower to mid-20s. Skies will slowly clear into Wednesday as high pressure nudges into the area, with sunshine and breezy westerly winds leading to high temperatures in the upper 30s to near 40 degrees.
-Dry but cooler until the weekend. Behind the cold front, observed wind gusts are highly variable but are closer to 35 mph than 45 mph.
144 PM PDT Tue Mar 26 2024 A weak ridge will move over the southwestern part of the country, leading to our warmest day of the week. This will be short-lived as a strengthening low pressure system from the north moves into the area later this week.
High pressure brings drier conditions late in the work week. Lingering light showers continue as a weak cold front arrives to the Middle Ohio valley early this evening. The cold front slowly exits east of the Appalachians Wednesday evening.
Discussion: Late this afternoon winds are still strong out of the southeast ahead of a cold front moving into middle Tennessee. Have just cancelled the High Wind Warning with gusts now less than about 40 mph in the eastern Tennessee mountains.
This will allow for the cold front to push drier air further east into our forecast area later this evening. /CR/ Quiet conditions are expected to persist through the week as high pressure moves into the region.
1228 PM CDT Tue Mar 26 2024 (Today and tonight) A broad trough will continue moving across the central US today.
We should see temperatures fall quickly this evening, with lows in the lower 40s north. mid and upper 40s central and south and the lower and mid 50s along the coast. A broad trough at the mid/upper levels is set to move east across the Plains tomor- row.
213 PM MDT Tue Mar 26 2024 - Warming trend begins tomorrow and continues over the weekend before the next system moves in, bringing precipitation chances and cooler temperatures.
(This evening through Wednesday Night) Relatively quiet and cooler than normal weather will continue through the next 36 hours across the Four State Region. This is due to post-frontal surface ridging that will gradually make its way south from the Great Plains, maintaining northeasterly winds.
Winds will shift to NW overnight, with some cooler air filtering in behind the front (mid 40s in the NW).
A short lived ridge of high pressure will build over western Montana and north central Idaho for Wednesday.
246 PM EDT Tue Mar 26 2024 Mild air streaming northwards ahead of a slow moving cold front will maintain above normal temperatures through at least Wednesday.
246 PM CDT Tue Mar 26 2024 - Lows tonight will be below or near freezing. There is an area of mixed vegetation susceptibility to the below freezing temperatures, so protect vulnerable vegetation.
1219 PM CDT Tue Mar 26 2024 Showers and isolated thunderstorms will move through northeast Mississippi this morning ahead of a cold front which will exit the Mid-South by this afternoon. Cooler and drier air will start to move into the region behind the front.
349 PM EDT Tue Mar 26 2024 Dry high pressure continues with more seasonable temperatures for today.
Mild and dry conditions will prevail through Easter weekend as high pressure dominates.
With the ridge passing through the area, light and variable winds are expected, starting the day out of west/northwest before slowly turning southerly during the evening and overnight hours. Hi-res guidance is in decent agreement in flurries passing approximately along the highway-32 corridor.
A cold front is also approaching NW AL in the wake of the exiting rainfall and will cross into the area later this afternoon. Clearing skies are accompanying the oncoming cold front and cloud cover should begin to diminish from west to east later this afternoon as well. The front will continue to sweep eastward thru the remainder of the area this evening, with cooler/drier air in tow. Overnight lows will fall mainly into the lower 40s/near 40F for most spots.
700 PM CDT Tue Mar 26 2024 (This evening through Wednesday) Many locations dipped below freezing this morning, with the West Texas Mesonet at Sterling City bottoming out at 26 degrees! This afternoon has remained in the cool side despite the abundant sunshine. Temperatures as of the 2 PM hour are in the lower to mid 50s in the Big Country and the the mid 50s to mid 60s across the remainder of the area. For Wednesday expect more sunshine and warmer temperatures, with highs warming into the upper upper 60s to mid 70s.

858 PM CDT Tue Mar 26 2024 - Warmer weather is expected the remainder of this week as an upper level ridge of high pressure builds eastward from the Rockies.
A few showers early this evening then clearing skies with a cool overnight lows with freezing temperatures for the colder areas of Cochise county.
Aside from a few stray mid level clouds moving through the area, mostly to partly clear conditions will prevail through the night with temps dipping down to the low 40s. Something else of note: while impacts will be negligible tonight, a secondary cold front is currently moving through the area. This cold front is tied to a much larger cyclone in the Great Lakes region and associated upper level trough progressing east. Current observations indicate the cold front is just west of us based on wind direction and dew points. A slight increase in wind and change in wind direction will really be the only notable changes as the cold front moves through.
A brief period of mild weather is forecast for tomorrow, before the next period of cooler temperatures and unsettled weather moves into the region. Upper level ridging then shifts east across the Rockies, tonight and tomorrow, for a drier period with temperatures warming back to seasonal levels.
(Tonight through Wednesday night) Key Messages: -Low Potential for Showers Tomorrow -High Risk for Rip Currents The High Rip Current risk was extended through 12Z Wednesday as long period swells (9-10 seconds) continue to push into the area, with offshore waves height around 7-8 feet. The only other thing worth mentioning in the forecast will be the low chance of showers tomorrow. If the lower levels can become moist enough to overcome the drier air the showers will be possible from the Northern Brush Country and Northern Coastal Plains to the Victoria Crossroads. Low temperatures are expected to be somewhat cooler tonight with widespread 50s expected.
931 PM EDT Tue Mar 26 2024 Mild air streaming northwards ahead of a slow moving cold front will maintain above normal temperatures through at least Wednesday, but the more comfortable conditions will be accompanied by the potential for some showers.
628 PM CDT Tue Mar 26 2024 (Through tonight ) At mid afternoon a mid level trof axis was exiting Northeast Oklahoma. light winds will help temps fall below freezing across the northern half of the CWA with mid 30s common across the southern half. there remains a slight chance of light rain developing with the mid/upper level low across parts of Eastern Oklahoma during day.

Cloud cover should also taper off and exit from west to east Wednesday night with another cool night for parts of Northeast Oklahoma and far Northwest Arkansas reaching down to near freezing.
Look for a warmup with dry conditions and gusty winds tomorrow ahead of another low pressure system that will bring cooler temperatures and more rain and snow to the area for the remainder of the week.
Cold front also has shifted quickly northeast of the area as well, with cold air advection on gusty west winds in its wake. Lows in the lower to middle 20s are expected tonight, with highs in the upper 30s to around 40 for Wednesday. As the parent low pressure system pivots northeastward out of Wisconsin into Ontario, winds will become westerly and gusts will diminish. Expect low temperatures in the lower to mid-20s. Skies will slowly clear into Wednesday as high pressure nudges into the area, with sunshine and breezy westerly winds leading to high temperatures in the upper 30s to near 40 degrees.
928 PM EDT Tue Mar 26 2024 Pre-frontal trough is situated across central portions of the CWA this evening. Along and south of the trough, scattered showers and a few thunderstorms persist. The high res-models keep this activity around most of the nighttime and doesn't really push it out until the actual front moves through tomorrow. Winds will shift to NW overnight, with some cooler air filtering in behind the front (mid 40s in the NW).
627 PM CDT Tue Mar 26 2024 - Widespread sub-freezing temperatures tonight with most locations in the teens and 20s.

Low temperatures are expected to be somewhat cooler tonight with widespread 50s expected.
851 PM CDT Tue Mar 26 2024 A cold front can be seen on IR satellite and radar passing through the area. Skies will be mainly clear overnight with winds decreasing closer to dawn as high pressure influences move in from the northwest. The wild card for today is how warm will afternoon highs get, the rain and cloud cover has kept things cooler but once we see some clearing things should warm up quickly. Highs should reach the upper 60s to low 70s except on the Plateau where it will stay cooler. We will remain in a troughing pattern on Wednesday and with the cold front off to our east it will be much cooler. Strong upper level ridge will be building over the central part of the country with high pressure over our region.
620 PM CDT Tue Mar 26 2024 Mild and dry conditions will prevail through Easter weekend as high pressure dominates.
613 PM CDT Tue Mar 26 2024 - Warmer weather is expected the remainder of this week as an upper level ridge of high pressure builds eastward from the Rockies.
This ridge is responsible for moderate east southeasterly breezes across the Keys and maintaining an influx of warmer moisture rich air. Short Term Update - The previously mentioned ridge will remain fairly stationary through the night and will maintain gentle to moderate southeasterly breezes across the Keys. With that said, it will be somewhat muggy with dew points remaining in the lower 70s and temperatures going nowhere.
(The rest of tonight) Sfc ridging continues to settle across the region and winds will go light area wide overnight. Expectations remain for below freezing temps across NE OK and far NW AR with no changes planned to the ongoing freeze warning. there remains a slight chance of light rain developing with the mid/upper level low across parts of Eastern Oklahoma during day. Any activity development north of the Red River should weaken by Wednesday evening as the mid/upper level trof axis moves through and exits the region. Cloud cover should also taper off and exit from west to east Wednesday night with another cool night for parts of Northeast Oklahoma and far Northwest Arkansas reaching down to near freezing.
510 PM MDT Tue Mar 26 2024 - Warming trend begins tomorrow and continues over the weekend before the next system moves in, bringing precipitation chances and cooler temperatures.
800 PM EDT Tue Mar 26 2024 The overall synoptic pattern remains rather amplified across the region this evening, with southwest flow aloft in between ridging to our south and troughing across the central part of the country. At the surface, high pressure is centered east of the state with an area of low pressure and associated cold front located to the northwest.
635 PM CDT Tue Mar 26 2024 - Lows tonight will be below or near freezing. There is an area of mixed vegetation susceptibility to the below freezing temperatures, so protect vulnerable vegetation.
A brief period of mild weather is forecast for tomorrow, before the next period of cooler temperatures and unsettled weather moves into the region. Patchy fog is possible, mostly for areas east of a line from Cut Bank to Lewistown, as warmer air moves in over the colder surface. Otherwise, skies should become partly cloudy after 03Z as a high pressure ridge starts moving into the area, which may allow patchy fog and low clouds with periods of MVFR/IFR conditions to develop after 08Z and continue through around 17Z. Upper level ridging then shifts east across the Rockies, tonight and tomorrow, for a drier period with temperatures warming back to seasonal levels.
812 PM CDT Tue Mar 26 2024 (This evening through Wednesday Night) Relatively quiet and cooler than normal weather will continue through the next 36 hours across the Four State Region. This is due to post-frontal surface ridging that will gradually make its way south from the Great Plains, maintaining northeasterly winds.
826 PM MDT Tue Mar 26 2024 - Warming trend begins tomorrow and continues over the weekend before the next system moves in, bringing precipitation chances and cooler temperatures.
1230 AM CDT Wed Mar 27 2024 - Warmer weather is expected the remainder of this week as an upper level ridge of high pressure builds eastward from the Rockies. with highs only near freezing across the heavy snow covered areas in portions of north central Nebraska.
1207 AM CDT Wed Mar 27 2024 (Tonight through Wednesday night) Key Messages: -Low Potential for Showers Tomorrow -High Risk for Rip Currents The High Rip Current risk was extended through 12Z Wednesday as long period swells (9-10 seconds) continue to push into the area, with offshore waves height around 7-8 feet. The only other thing worth mentioning in the forecast will be the low chance of showers tomorrow. If the lower levels can become moist enough to overcome the drier air the showers will be possible from the Northern Brush Country and Northern Coastal Plains to the Victoria Crossroads. Low temperatures are expected to be somewhat cooler tonight with widespread 50s expected.
Convection/narrow cold frontal rain band feature clears the area to the east by 7 PM then the colder air rushes in in behind the cold front. Lows dipping down to near freezing tonight. - Dry/Cool to End The Workweek Low strato-cu clouds lingering much of Wednesday due to cold cyclonic flow but some clearing arriving by late in the day as sfc ridging starts to nudge in. Better prospects for sunny skies on Thursday per ensemble cloud fcsts as dew points continue to lower in very dry air mass-- despite lingering troughing and cold air aloft.
The main one will be low pressure moving from Georgia to the Carolina coastline through Thursday morning. This will bring better rain chances east of the Blue Ridge today into tonight.
