300 PM EDT Sat Mar 23 2024 Snow will come to an end this evening as low pressure pulls away to the north and east.
High pressure will bring a cold night to the Mid-South tonight with lows in the 30s.
(Tonight) Overnight, dry weather will continue to remain in place with clear skies as high pressure influences the region.
MM/25 (Now through Sunday) An upper level trough continues to pivot eastward across Alabama and the western Florida panhandle early this morning. A drier northwesterly flow pattern aloft will develop over our region in the wake of the passing trough this afternoon through tonight. A surface cold front will sweep across our forecast area this morning with northerly winds increasing to 10-20 mph with gusts of 25-35 mph following the passage of this feature. Light northeasterly winds in the morning should turn southeasterly to southerly in the afternoon as surface ridging advances eastward toward the Eastern Seaboard. Highs today and Sunday should range in the lower to mid 70s inland and in the upper 60s to lower 70s along the coast.
A cold front will progress southeastward into east- central Nevada this evening bringing valley rain or rain/snow mix and higher elevation snow to the area.
A low pressure system is circulating just off the Washington coast, which has continued to draw moisture from south to north throughout the day. As the low moves inland, additional moisture will pivot across the Northern Rockies, bringing a more potent round of snowfall tonight through Sunday morning to southwest Montana locations, including: Phillipsburg, Georgetown Lake, and the general I-90 corridor region from Drummond to Homestake Pass. MacDonald Pass will also see continued snowfall and impacts to travel during this time, as well as the higher terrain of Clearwater and Idaho counties in Idaho.
Some of the highlights of today's severe weather episode were a handful of around 50 knot wind gusts recorded by various marine observation platforms, as well as a few spin-ups within storms, one of which prompted a tornado warning for portions of the Lower Keys. A cold front will move across the Keys forecast area, which will usher in a much drier airmass and deflate rain chances to near nil through at least the first half of the week.
(Rest of today through Sunday) All showers have left the mid state following last evening's trough passage. High pressure centered over the Upper Midwest is now building into the region, so we can enjoy decreasing cloudiness today, along with a brisk northerly wind and cooler temperatures. Overnight readings will drop into the 30s, but we'll start to pick up some return flow tomorrow and appreciably warmer weather.
Near freezing to below freezing temperatures expected area-wide tonight. Areas along and north of Interstate 40 could see sub freezing temperatures, while locations to the south of the Interstate will still see temperatures drop into the 30s. AReas in the higher elevations will likely drop well below freezing overnight. After sunrise the temperatures will quickly jump back up above freezing and into the 50s before noon.
The current forecast has the highest PoPs east of an Abilene to San Angelo line, with much lower chances across our western counties.
1242 PM CDT Sat Mar 23 2024 Latest surface analysis had the cold front southeast of our CWA. This will gradually taper off over the next few hours as sfc front to the northwest swings in, helping dry out moist profiles aloft & eventually scour out the low-level moisture/clouds into the aftn hours. Highs will be seasonably cool, some 3-5 degrees below normal, in the low 60s northwest to near 70 degrees in the Pine Belt.
326 PM EDT Sat Mar 23 2024 - Rain ends this morning from northwest to southeast as a cold front passes across the region and brings gusty north winds through this afternoon. - Widespread freezing temperatures are forecast for tonight into Sunday morning.
1229 PM CDT Sat Mar 23 2024 - Sub freezing temperatures this morning across the regions.
330 PM EDT Sat Mar 23 2024 High pressure will build across the area tonight and pass off to the east on Sunday.
225 PM EDT Sat Mar 23 2024 A low pressure system maintains cooler temperatures today.
1237 PM CDT Sat Mar 23 2024 15Z surface analysis places a cold front from the Mid-Atlantic States back through portions of the Lower Mississippi Valley and Texas near the northern Gulf Coast.
207 PM EDT Sat Mar 23 2024 Drier weather will gradually build across the area tonight in the wake of the cold front.
1222 PM CDT Sat Mar 23 2024 (Today through Sunday Night) A cold front is moving SE through central into SERN sections of the CWA early this Sat morning. The NRLY winds will decrease also by this afternoon/evening as high pressure moves closer to the state. Dry and quiet conditions will be seen for tonight into Sun as the high pressure moves over the region.
1220 PM CDT Sat Mar 23 2024 (Rest of today through Sunday) All showers have left the mid state following last evening's trough passage. High pressure centered over the Upper Midwest is now building into the region, so we can enjoy decreasing cloudiness today, along with a brisk northerly wind and cooler temperatures. Overnight readings will drop into the 30s, but we'll start to pick up some return flow tomorrow and appreciably warmer weather.
1037 AM CDT Sat Mar 23 2024 15Z surface analysis places a cold front from the Mid-Atlantic States back through portions of the Lower Mississippi Valley and Texas near the northern Gulf Coast.
Moisture is advecting in from the Pacific and Gulf of Mexico with a broad low pressure system continuing to develop over Colorado. In fact, up to a quarter of the latest GFS ensemble solutions keep Plentywood dry, giving the lowest confidence for impacts there while winds still gust up to 40 mph.
An upper low offshore will continue to bring unsettled conditions through the weekend.
This activity is developing along a secondary cold front. Drier and cooler air will filter in overnight behind the departing front.
605 PM CDT Sat Mar 23 2024 (Rest of today through Sunday) All showers have left the mid state following last evening's trough passage. High pressure centered over the Upper Midwest is now building into the region, so we can enjoy decreasing cloudiness today, along with a brisk northerly wind and cooler temperatures.

1026 PM EDT Sat Mar 23 2024 A low pressure system maintains cooler temperatures today.
854 PM EDT Sat Mar 23 2024 Clearing skies tonight with northerly winds increasing behind a cold front.
This activity is developing along a secondary cold front. Drier and cooler air will filter in overnight behind the departing front. A secondary cold front will push through this evening.
Cold air and associated instability is gradually building aloft as the upper level low dips across the area. Light snow will continue to fall along the highest passes of Highway 36 and 3 in Trinity County this evening as showers push east. Only minor accumulation is expected with 1 to 3 inches below 4000 feet and 3 to 8 inches on the highest mountains.
717 PM EDT Sat Mar 23 2024 High pressure will build across the area tonight and pass off to the east on Sunday.
946 PM EDT Sat Mar 23 2024 High pressure will build across the area tonight and pass off to the east on Sunday.
943 PM EDT Sat Mar 23 2024 Drier weather will gradually build across the area tonight in the wake of the cold front.
This clearing was coincident with a cold front passage. The cold front is not particularly strong with temperatures still in the lower to mid 70s. However, dew points have fallen into the lower to mid 60s due to drier air flooding in on gentle to moderate northwesterlies. High pressure that is partially responsible for ushering through the cold front blankets the eastern United States and steadily spreading southeastward across our area. Short Term Update - Previously mentioned high pressure will continue to expand southeastward across our area and into the Atlantic. A cold front has swept out all heavy shower and thunderstorm activity earlier in the afternoon and evening. High pressure building southeastward across our area will result in freshening northwesterly breezes on Keys waters over the next few hours.
Freezing level around 5500/6500 feet above sea level.
A cold front is forecast to gradually push through overnight, and winds will veer north-northwesterly behind the frontal passage, becoming gustier toward daybreak Sunday. Boating conditions are forecast to deteriorate quickly tonight as a cold front moves across the local waters. Light SHRA are moving south, along with a cold front.
604 PM CDT Sat Mar 23 2024 High pressure will bring a cold night to the Mid-South tonight with lows in the 30s.
Near freezing to below freezing temperatures expected area-wide tonight. Areas along and north of Interstate 40 could see sub freezing temperatures, while locations to the south of the Interstate will still see temperatures drop into the 30s. Areas in the higher elevations will likely drop well below freezing overnight. After sunrise the temperatures will quickly jump back up above freezing and into the 50s before noon.
As winds aloft back from NNW-to-WNW following the passage of the ridge axis, a notable increase in the coverage of high-level clouds is expected to occur during the early morning hours.
558 PM EDT Sat Mar 23 2024 A low pressure system maintains cooler temperatures today.
At the surface, a high pressure axis extending into the Lower Mississippi Valley will continue to shift eastward overnight tonight while a strengthening Lee cyclone takes shape over the High Plains to the west. Southerly winds and increasing moisture will allow for much milder temps tonight compared to last night as lows generally will stay in the lower 40s across western Arkansas to near 50 across parts of eastern Oklahoma. Any shower activity still looks to remain west of the area overnight tonight within the better moisture return axis within the axis of the low level jet. There is some potential for similar gusts in the higher terrain areas of northwest Arkansas and possibly, southeast Oklahoma but will hold off on an advisory for now given lower confidence and likely, a later onset.
758 PM CDT Sat Mar 23 2024 Tonight and Sunday: Continued dry and cooler than normal through the period. Mid afternoon surface analysis had a 1030mb high centered over the northern Great Lakes region ridging south just west of our CWA.
649 PM CDT Sat Mar 23 2024 (Tonight) Overnight, dry weather will continue to remain in place with clear skies as high pressure influences the region.
716 PM EDT Sat Mar 23 2024 Drier weather will gradually build across the area tonight in the wake of the cold front.
Sunny and warmer today with high pressure in control. Low RH values expected today with the warmer temperatures and dry air. With these warmer temperatures and the dry airmass, low RH values are expected area-wide.
1140 PM EDT Sat Mar 23 2024 - Widespread freezing temperatures are forecast for late tonight into Sunday morning, and in many valleys late Sunday night into Monday morning.
125 AM EDT Sun Mar 24 2024 Upper ridging builds over the area today into Monday. A slow- moving cold front is expected move through the area during the mid- week period with the next chance of showers.
1252 AM CDT Sun Mar 24 2024 Tonight and Sunday: Continued dry and cooler than normal through the period. Mid afternoon surface analysis had a 1030mb high centered over the northern Great Lakes region ridging south just west of our CWA.
338 AM EDT Sun Mar 24 2024 - Freezing temperatures are forecast for some of the deeper valleys tonight.
1257 AM EDT Sun Mar 24 2024 Upper ridging builds over the area today into Monday. A slow- moving cold front is expected move through the area during the mid- week period with the next chance of showers.
At the surface, a high pressure axis extending into the Lower Mississippi Valley will continue to shift eastward overnight tonight while a strengthening Lee cyclone takes shape over the High Plains to the west. Southerly winds and increasing moisture will allow for much milder temps tonight compared to last night as lows generally will stay in the lower 40s across western Arkansas to near 50 across parts of eastern Oklahoma. Any shower activity still looks to remain west of the area overnight tonight within the better moisture return axis within the axis of the low level jet.
218 AM EDT Sun Mar 24 2024 Upper trough down the Eastern Seaboard early this morning continues to move into the W Atlantic today while upper ridging quickly builds from the Gulf of Mexico into the Deep South. Main weather hazard will be the high rip current risk along area beaches today as residual elevated Gulf seas move ashore.
1116 PM CDT Sat Mar 23 2024 (Tonight through Monday night) Beautiful and dry conditions are present today and across the region, all thanks to a cool airmass and ridging aloft.
138 AM EDT Sun Mar 24 2024 Drier weather will gradually build across the area tonight in the wake of the cold front.
155 AM EDT Sun Mar 24 2024 High pressure will build across the area tonight and pass off to the east on Sunday.
359 AM EDT Sun Mar 24 2024 High pressure will gradually build into the region today and hold through the first half of the week.
133 AM EDT Sun Mar 24 2024 - Widespread freezing temperatures are forecast for late tonight into Sunday morning, and in many valleys late Sunday night into Monday morning.
400 AM EDT Sun Mar 24 2024 - Dry and warmer today with highs near 50.
The net effect will be an axis of heavy rainfall that develops along the cold front.
An upper-level area of low pressure over the Pacific Northwest will open up into a trough of low pressure this morning. This trough of low pressure will rapidly move southward, passing across Central California this afternoon into this evening. The highest probability of thunderstorms will be confined to areas south of Fresno County this afternoon. A ridge of high pressure will move eastward across the Eastern Pacific Ocean Monday.
Today cooler than average temperatures persist despite low level ridging arriving across the forecast area. Temperatures this afternoon may remain in the 40s for most with some reaching the low 50s max. Also expanding cloud cover will help hold slightly warmer temperatures in, so no sub-freezing temperatures are expected for the overnight tonight. But current thinking is that most will stay dry with fairly dry conditions persisting in the low levels. Heading into Sunday, the forecast gets more interesting as a deep trough over the western US ejects a wave toward our forecast area.
Otherwise, dry weather with above normal temperatures will occur in addition to the wind courtesy of a nearly zonal mid-level flow and despite the Monday passage of a cold front. Finally, with strong winds and rough seas along the Lower Texas Coast, a High Risk of rip currents will exist at the local beaches until around sunset Monday.
Conditions will change on Monday as a strong upper level low treks across the Central Plains.
Deep upper level troughing dominates across the northeastern states as an additional weak frontal boundary pushes through the area today. Surface flow will veer more northeasterly by the evening hours as high pressure begins to build back across the area.
The base of a deep 500 mb trough will move across the area, along with a potent ~50 kt low- level jet. However strongest forcing associated with the aforementioned upper trough combined with a slight more southerly oriented flow may lead to a few isolated to scattered storms across the far southeastern Panhandle and eastern Rolling Plains.
The grand ensemble also shows the highest winds occurring on Monday, with under a 20 percent chance of sustained winds exceeding 30 mph.
High pressure brings dry weather today through Monday. A center of high pressure over Michigan continues to allow pesky, grey stratocumulus decks along the mountains to clear as rising heights move southeastward. Temperatures will be mild, but still comfortable, with the lowlands and mountains seeing highs in the 50s to around 60, while the higher elevations will likely stay in the 40s. Clouds will build in from the southwest later tonight, as a warm front moves through the area.
A trailing cold front will move east into AR by Mon afternoon. Expect widespread convection to develop in vicinity of the EWD progressing cold front Mon.
A descending 500mb jet rounds the base of the synoptic trough centered over the SE CONUS, this large push of cyclonic vorticity advection hastens the development of the leeward cyclone which in turn tightens the pressure gradient across the Plains. A large area of relatively warmer and more moist air pools across central KS. As the cyclone pivots north and east through the day Monday more widespread showers and thunderstorms are expected over areas east of US-65.
The aforementioned track of this low continues to take a more southerly route than in previous days, which is leading to a continued decrease in forecast snow totals.
930 AM EDT Sun Mar 24 2024 A beautiful morning across the state with high pressure settling in behind the frontal passage we saw yesterday evening. Upper trough down the Eastern Seaboard early this morning continues to move into the W Atlantic today while upper ridging quickly builds from the Gulf of Mexico into the Deep South. Main weather hazard will be the high rip current risk along area beaches today as residual elevated Gulf seas move ashore.
644 AM EDT Sun Mar 24 2024 - Dry and warmer today with highs near 50.
The upper level low that was responsible for the inclement weather is now centered to our northeast and continuing to push eastward. Broad high pressure straddling the Great Lakes Region will quickly shift east through the day today. This will be short lived as the aforementioned low pressure system to our northeast moves into the North Atlantic and deepens. These two features will trap the high in place and allow for the pressure gradient to tighten across the Keys.
938 AM EDT Sun Mar 24 2024 High pressure will gradually build into the region today and hold through the first half of the week.
A cold front moved through and dew points dropped as low as the upper 50s, but have since rebounded to the lower 60s. Temperatures are in the lower to mid 70s, making it a very comfortable late March morning. GOES visible satellite is highlighting a boundary moving across the Lower Keys, which is likely just a Florida land breeze.
812 AM EDT Sun Mar 24 2024 Upper ridging builds over the area today into Monday. A slow- moving cold front is expected move through the area during the mid-week period with the next chance of showers.
(Today and tonight) Early this morning, an upper-level trough was digging southward over the Four Corners region. The aforementioned upper low should track through the Rockies and into western Kansas today. Some gusts near 50 are possible, but this should be confined to the highest elevations, such as the hills south of Abilene. Storms should develop just ahead of this cold front/dryline combo late this afternoon and and evening, then push eastward.
-Period of mixed freezing rain/snow along and south of I-90 today. Mix of precipitation across the forecast area, with snow across northwest South Dakota and freezing rain/snow across south central South Dakota. For south central South Dakota, the freezing rain/snow this morning may transition to rain as warm air aloft nudges northward.
At the surface, a cold airmass associated with high pressure in central Canada surged south through remaining portions of southwest MT overnight behind low pressure tracking east across WY. Roads could be particularly icy this morning across portions of SW MT, where snow amounts were lighter, but road surfaces were also warmer leading some initial melting.
803 AM EDT Sun Mar 24 2024 Upper trough down the Eastern Seaboard early this morning continues to move into the W Atlantic today while upper ridging quickly builds from the Gulf of Mexico into the Deep South. Main weather hazard will be the high rip current risk along area beaches today as residual elevated Gulf seas move ashore.
633 AM CDT Sun Mar 24 2024 (Today and tonight) Early this morning, an upper-level trough was digging southward over the Four Corners region. The aforementioned upper low should track through the Rockies and into western Kansas today. Some gusts near 50 are possible, but this should be confined to the highest elevations, such as the hills south of Abilene. Storms should develop just ahead of this cold front/dryline combo late this afternoon and and evening, then push eastward.
As for West of the Divide, for now we have left the highlights alone. Like in the west, snow should taper off before sunset as the cold front and trough move away from the area.
419 AM CDT Sun Mar 24 2024 - Rain and freezing rain (and a few rumbles of thunder) continue to slide across the area this morning. - Severe thunderstorms are possible late this afternoon and evening, the main risk area southwest of a line from Cambridge to Beloit, and the main timeframe for severe is 4pm to midnight.
1004 AM EDT Sun Mar 24 2024 Dry, quiet weather is expected today into tomorrow under high pressure.
The highest winds will remain along the coast north of the Cape, where a Wind Advisory is in effect. Cooler temperatures this afternoon compared to earlier this weekend, with highs in the low to mid-70s. Very hazardous boating conditions today, as windy conditions persist due to a tight pressure gradient between departing low pressure and building high pressure to the north.
The low pressure system that has brought our recent wet and active weather is currently centered over west-central Oregon. Several bands of showers are traversing eastwards across the area as they swing under the low. Generally light, isolated showers will stick around into the early evening today, however, generally along the coast/into Douglas County and the Cascade ridge. A weakening ridge blasts through the region late this evening into early Monday, before northwest flow resumes.
613 AM CDT Sun Mar 24 2024 - Rain and freezing rain (and a few rumbles of thunder) continue to slide across the area this morning. - Severe thunderstorms are possible late this afternoon and evening, the main risk area southwest of a line from Cambridge to Beloit, and the main timeframe for severe is 4pm to midnight.
The bulk of the showers associated with the upper low have moved south as the low has opened and the upper trough is moved south of the region.
1212 PM EDT Sun Mar 24 2024 - Dry and warmer today with highs near 50.
241 PM EDT Sun Mar 24 2024 High pressure centered over Quebec will assure that most areas will experience moonlit skies tonight with another day of full sunshine on Monday. The start of the new work week will also mark a period of notably warmer weather.
Temperatures have been subdued to the 70s, and dew points have stayed comfortable in the lower 60s. Today's brief instance of lighter winds will quickly be replaced with freshening breezes as high pressured centered near Maine builds down the Eastern Seaboard. This high will be caught between two low pressure systems, one centered near Bermuda and the other over the Plains.
MM/25 (Now through Monday) Dry and pleasant conditions will continue today into tonight as upper level ridging moves over the area. With high pressure in control over the area; expect clear skies with drier air across the area.
1249 PM EDT Sun Mar 24 2024 Dry, quiet weather is expected today into tomorrow under high pressure.
320 PM EDT Sun Mar 24 2024 The region will remain under the influence of high pressure centered to the east through Monday.
(Monday Night through next Sunday) A strong cold front will close in on Middle Tennessee Monday night, with widespread showers and storms developing during the evening.
This is all thanks to ridging sitting over the area. Highs on Monday will be in the low to mid 80's.
- Monday and Monday Night will be warmer with periodic rain showers.
(Rest of today through Monday) Mostly dry and pleasant weather continues through the short term as mid-level ridging builds over the Gulf of Mexico and the Deep South.
