1232 AM CDT Mon Apr 7 2025 (Rest of tonight and Monday) Light to occasionally moderate showers will continue to taper off tonight as a cold front moves through the area. Drier air will slowly start to filter into the forecast area tonight and on Monday as high pressure builds to our west and an upper trough axis pushes east and centers over the Appalachians into the Tennessee Valley.
A cold front, currently analyzed from Kewaunee to Wautoma, continues to sink south early this morning. Doppler radar trends show the snow behind the cold front is diminishing rapidly, and mainly confined to northeast Wisconsin, where mid level frontogenesis and moisture coincide with a boost in moisture from Lake Superior. Behind the cold front, lake effect snow showers will still be possible across north-central Wisconsin with northerly surface winds. Winds will increase behind the cold front today, with north-northwest winds gusting to 25 to 35 mph. High pressure will then build in across the region, with dry weather expected tonight through Tuesday night.
Any brief intrusion of cooler air is expected to be short-lived with some low level warm air advection progged to develop as we move through the overnight hours.
319 AM CDT Mon Apr 7 2025 - Sub-freezing temperatures are expected again tonight. Skies will remain mostly clear with highs reaching the lower 60s. A Freeze Warning is currently in effect until 9 AM this morning for sub-freezing temperatures occurring across the area. Went ahead and upgraded the Freeze Watch to a Freeze Warning for all of the CWA again tonight from 11 PM to 9 AM Tuesday for sub- freezing temperatures occurring again tonight (27-33 degrees). Mid-level high pressure moves over the area on Tuesday and warm air advection will allow us to warm up through the rest of the week with highs reaching the 60s and 70s by mid-week.
(Rest of tonight and Monday) Light to occasionally moderate showers will continue to taper off tonight as a cold front moves through the area. Drier air will slowly start to filter into the forecast area tonight and on Monday as high pressure builds to our west and an upper trough axis pushes east and centers over the Appalachians into the Tennessee Valley.
1058 PM CDT Sun Apr 6 2025 - Cool tonight with lows near freezing. At the surface, high pressure has built in over Kansas and driven periods of breezy north winds over the forecast area so far today. With little to no cloud coverage anticipated alongside these light winds, radiational cooling is expected to result in temperatures near to below freezing tonight. As the upper ridge slides eastward, dry and warming conditions are expected with highs near 70 by Tuesday.
307 AM CDT Mon Apr 7 2025 - Windy and cold day today with highs barely in the 40s and lows well below freezing. A cold front will move into the area this morning bringing colder and drier air to the area. Tonight the well advertised temperatures below freezing continue to be on track. Lows in the low to mid 20s are expected. The day will start out cold but with the ridge in place light winds are expected. Temperatures will be warmer than today and it will be like yesterday. As the ridge moves off to the southeast and upstream steering flow flattens, increasing return flow both at the sfc and especially aloft may generate a wing of showers somewhere acrs the region from late Tue night into Wed.
Lows will be around 15 degrees below normal in the lower 30s north to the middle 40s southwest. A few spots in the Hill Country may see a few hours of near freezing temperatures and possibly a light freeze. Monday high pressure will move over the region. Highs Monday will be 10-15 degrees warmer than today. This warming will continue Monday night, and lows Tuesday morning will be about five degrees warmer than Monday.
Tuesday will be a tad bit warmer as 850mb temperatures begin to increase, so expecting highs in the low to mid 70s underneath clear skies. So, enjoy the cooler air while we have it.
High pressure is settling south and will be north of Winnipeg at 12z Mon. High pressure will move south and be over the Red River valley late this aftn/eve giving light winds. 500 mb ridge builds into the northern plains Fri-Sat giving warmer temps. ECMWF is more agressive and digs the 500 mb waver farther south, before taking the wave and associated low pressure system from Colorado into eastern ND by 00z Mon.
A brief transition to light snow is possible along the highest peaks of the mountains, but accumulations are not expected. Temperatures will be cool through the day with many places dropping to near freezing tonight. Today Currently early this morning, a trough is centered just to our west with a jet streak extending into the eastern Great Lakes. Tonight Continued CAA will usher in conditions that do look sufficient for a brief transition to light snow along the highest peaks of the mountains. By early Tuesday morning, deep troughing will remain in place with Canadian high pressure becoming centered just to our northwest. The increasing subsidence and recent CAA will allow temperatures to drop to around freezing area-wide.
1240 AM EDT Mon Apr 7 2025 - Cooler and breezy with rain and snow showers Monday.
226 AM EDT Mon Apr 7 2025 - Brief Burst of Snow Monday Morning - Rain/Snow Chances Midweek No changes to the going forecast at this time but it should be noted that the new 00Z HRRR has backed off considerably on tomorrow morning's quick snow burst with the cold frontal passage. - Brief Burst of Snow Monday Morning A quick moving cold front will swing through Monday morning.
134 AM EDT Mon Apr 7 2025 (Rest of today through Monday) Latest model guidance and satellite analyses show a large trough/low complex migrating across the C CONUS with an associates sfc frontal boundary moving into the SE states. Meanwhile, SoFlo remains under the influence of the western periphery of a deep high pressure system centered over the west Atlantic. Higher dew points will translate in warmer conditions with afternoon highs climbing into the low-mid 90s over interior areas, and mid-upper 80s near the coasts.
1049 PM CDT Sun Apr 6 2025 Updated at 1038 PM CDT Sun Apr 6 2025 - Freeze Warning is in effect tonight into tomorrow morning - Mild and dry conditions are expected this coming work week (Rest of today and tonight) The mid-level trough axis continues to progress across the FA into this evening and expect gradual clearing to occur behind this axis. High temperatures will range from the low-70's (southeastern and central Oklahoma) to the upper-70's (west) and wind gusts of 30 to 35 mph are possible (northwest).
High pressure is settling south and will be north of Winnipeg at 12z Mon. High pressure will move south and be over the Red River valley late this aftn/eve giving light winds. 500 mb ridge builds into the northern plains Fri-Sat giving warmer temps. ECMWF is more aggressive and digs the 500 mb waver farther south, before taking the wave and associated low pressure system from Colorado into eastern ND by 00z Mon.
1021 AM EDT Mon Apr 7 2025 A cold front will slowly progress east across the area through tonight.
High pressure and hot weather build into the region this week with many high temperature records in jeopardy.
532 AM CDT Mon Apr 7 2025 - Sub-freezing temperatures are expected again tonight. Skies will remain mostly clear with highs reaching the lower 60s. A Freeze Warning is currently in effect until 9 AM this morning for sub-freezing temperatures occurring across the area. Went ahead and upgraded the Freeze Watch to a Freeze Warning for all of the CWA again tonight from 11 PM to 9 AM Tuesday for sub- freezing temperatures occurring again tonight (27-33 degrees). Mid-level high pressure moves over the area on Tuesday and warm air advection will allow us to warm up through the rest of the week with highs reaching the 60s and 70s by mid-week.
414 AM CDT Mon Apr 7 2025 - Temperatures fall near or below freezing again Tuesday morning. Early this morning, the upper air pattern across the CONUS shows a positively tilted longwave trough slowly pushing east of the region. A sharp mid to upper level ridge is setup from the northern Plains through the Desert Southwest region with another Pacific trough advancing into the Pacific northwest region.
(Today) A freeze warning remains in effect early this morning as temperatures fall to near or slightly below freezing in most places by sunrise.
Pattern/synopsis: 1007mb low pressure is over Lake MI, off of the Dunes. The low will move e/ene across far northern lower MI, near M-32/M-68. Further deepening occurs over northern Lk Huron and Georgian Bay by late afternoon, with the low continuing east tonight. Pattern Synopsis and Forecast: Final burst of upper support is anticipated on Tuesday for portions of the region on the back edge of the upper trough that brought accumulating snows mainly to EUP on Monday. There will be a disturbance diving south from the N Plains to the OH Valley mid week along with a low pressure system formation.
High pressure will result in warm and dry conditions today. Strong high pressure will build in again afterwards, continuing into the weekend.
/NEW/ Update: Skies have cleared across the region early this morning with a few locations that have dropped to freezing across our west and northwest. Light north winds will become south tonight with overnight lows about 5 to 10 degrees warmer than this morning. Light winds and clear skies will allow temperatures to drop to or just below freezing across parts of the region, especially west of I-35. Low level winds will become southerly Monday night and overnight lows will be 5-10 degrees warmer with no freezing concerns. Southerly winds will increase to 10 to 15 mph on Tuesday with sunny skies continuing and temperatures climbing back into the low to mid 70s which is near normal for this time of year.
Temperatures are on track to reach the lower to mid 80s across the island chain and dew points are lingering in the lower 70s. The pronounced trough and frontal system associated with the days long severe weather event over the ArkLaTex region and the Tennessee valley finally moved east yesterday. The cold front will make its way across the Florida Panhandle this afternoon, and is forecast to move across the Florida Keys tomorrow night. The longwave trough associated with this front will direct a significant plume of moisture across the Keys starting tonight. From synopsis, moderate southeast breezes will continue to slowly slacken this afternoon as as a low pressure system deepens over the eastern United States. Southerly surface winds will veer later tonight as a cold front approaches the Keys.
613 AM CDT Mon Apr 7 2025 (Today through Tuesday) Deep South Texas and the Rio Grande Valley, initially under the influence of a zonal mid-level flow, will increasingly be dominated by 500 mb high pressure that will build over the northwest coast of Mexico.
Temperatures are a little warmer resulting in more rain than snow. - Brief period of light snow this morning possible, chilly Low pressure moving across northern Lower will pull a cold front south across the region today, ushering in another round of winter weather.
Increasing clouds and wind today as a cold front continues to move towards the state.
604 AM CDT Mon Apr 7 2025 - Temperatures fall near or below freezing again Tuesday morning. Early this morning, the upper air pattern across the CONUS shows a positively tilted longwave trough slowly pushing east of the region. A sharp mid to upper level ridge is setup from the northern Plains through the Desert Southwest region with another Pacific trough advancing into the Pacific northwest region.
(Today through Tuesday) In the wake of yesterday's cold front, cooler and drier will prevail across the region to begin the week as the ridge settles into the region.
There will be some gusty winds for the high deserts and mountain passes/canyons later today and tomorrow.
606 AM CDT Mon Apr 7 2025 (Today through Tuesday) In the wake of yesterday's cold front, cooler and drier will prevail across the region to begin the week as the ridge settles into the region.
734 AM EDT Mon Apr 7 2025 - Brief period of light snow this morning possible, chilly - Mid week mixed rain/snow - Brief period of light snow this morning possible, chilly Low pressure moving across northern Lower will pull a cold front south across the region today, ushering in another round of winter weather.
Light rain early today should taper off by mid-morning with lingering clouds and cooler temperatures. Warmer temperatures with minor HeatRisk return Tuesday for the remainder of the work week. (Today and tonight) Light rain will continue through sunrise across the North Bay and eventually taper off by mid morning as a weak cold front moves east across our area today. Clouds and cooler air today will briefly interrupt the warmup we saw over the weekend. Temperatures today will hover around normal, slightly warmer for some spots in our inland valley areas.
537 AM CDT Mon Apr 7 2025 - Windy and cold day today with highs barely in the 40s and lows well below freezing. A cold front will move into the area this morning bringing colder and drier air to the area. Tonight the well advertised temperatures below freezing continue to be on track. Lows in the low to mid 20s are expected. The day will start out cold but with the ridge in place light winds are expected. Temperatures will be warmer than today and it will be like yesterday. As the ridge moves off to the southeast and upstream steering flow flattens, increasing return flow both at the sfc and especially aloft may generate a wing of showers somewhere acrs the region from late Tue night into Wed.
An area of low pressure continues to spin off the coast of Oregon early this morning. Occasional rain showers continue today as the low moves onshore. Snow levels drop behind the low this morning to around 5000-6000 ft, which could bring a rain/snow mix to Highway 3 at Scott Mountain Pass if any showers pass through. Breezy winds of up to 35 mph are possible for exposed ridges and coastal headlands of Del Norte Tuesday. Ridging builds in midweek, bringing warm, sunny weather to the interior.
Upper ridging will continue building in over our region and just to our west today, giving us warm, dry, and generally quiet weather across SE Colorado. Today's high temperatures will warm a bit from yesterday, with mid-high 50s over the high valleys and mid-high 60s over the eastern plains.
Light rain late this afternoon into early evening especially north and east, then a few light rain showers later tonight mainly north and mountains with light snow showers possible over the highest peaks. Discussion: The upper level short wave trough to our west will move across the area early tonight and off to our east, and a reinforcing shot of colder air will push into the area behind a moisture starved cold front later tonight. As colder air pushes in later tonight on northwest winds there will likely be enough orographic lift to wring out a few light showers over the northern and eastern higher terrain later tonight, and by this time it may be cold enough for a few snow showers over the highest elevations. However, little or no accumulation is expected even over the highest peaks.
1205 PM CDT Mon Apr 7 2025 (Today through Tuesday) In the wake of yesterday's cold front, cooler and drier will prevail across the region to begin the week as the ridge settles into the region.
Lows are expected to generally be in the low to mid 40s with the exception being over the Hill Country where mid to upper 30s are expected. High pressure moves east off the coast for Tuesday which results in the return of southerly flow for us. Warmer highs can be expected on Tuesday with upper 70s to near 80 east and mid to upper 80s along the Rio Grande Plains. Lows Tuesday will be even warmer then tonights as most locations will drop down to the 50s.
/NEW/ /Through Tuesday/ Following an abnormally cold morning with temperatures 15-20 degrees below normal (and a handful of sites dipping to near or below freezing), ample sunshine will allow afternoon highs to climb into the 60s area-wide. A broad area of high pressure will encompass most of the Central CONUS through tomorrow with fair weather and clear skies in store.
- Windy and cold day today with highs barely in the 40s and lows well below freezing. A cold front will move into the area this morning bringing colder and drier air to the area. Tonight the well advertised temperatures below freezing continue to be on track. Lows in the low to mid 20s are expected. The day will start out cold but with the ridge in place light winds are expected. Temperatures will be warmer than today and it will be like yesterday. As the ridge moves off to the southeast and upstream steering flow flattens, increasing return flow both at the sfc and especially aloft may generate a wing of showers somewhere acrs the region from late Tue night into Wed.
(Rest of today and tonight) As of 1900UTC, a cold front was moving into southern Kansas with air temperatures in the 60's southward and 50's north of the boundary. Clear skies and light winds will allow for temperatures to decrease into the mid/upper-30's with a few areas in the low 40's, which is about a 5-10 deg improvement from last night's freezing temperatures.
1207 PM CDT Mon Apr 7 2025 - This week will be quiet for our area weather-wise, with overall temperatures much warmer and dry conditions. (Today and tonight) We have a chilly start to the day with temperatures around freezing across west central Texas. The 850mb thermal ridge should strengthen from the west, which should result in high temperatures in the upper 60s to around 70 this afternoon.
Otherwise, temperatures will continue to trend higher as the work week progresses as high pressure builds over the Great Basin. Pacific trough energy has moved east and is bringing with it clouds and very light showers. Highs will be a few degrees cooler than Monday but will still remain above normal levels with readings in the 60s to mid 70s.
A weak frontal system will continue to move east this morning with scattered showers and isolated thunderstorms developing this afternoon with slightly cooler air aloft.
High pressure will build over the central US through the middle of the week ushering in cooler drier air aloft into the area.
(Tonight through Tuesday night) High pressure has settled over Deep South Texas, resulting in clear skies, precipitation-free conditions, and pleasant temperatures. Tonight and tomorrow night's low temperatures are expected to be cool, with low temperatures in the upper 40s/lower 50s tonight, and the low-to-mid 50s tomorrow night. Radiational cooling due to clear skies and light winds could result in even cooler temperatures in localized areas.
1206 PM CDT Mon Apr 7 2025 - Temperatures fall near or below freezing again Tuesday morning. Early this morning, the upper air pattern across the CONUS shows a positively tilted longwave trough slowly pushing east of the region. A sharp mid to upper level ridge is setup from the northern Plains through the Desert Southwest region with another Pacific trough advancing into the Pacific northwest region.
Deeper moisture in the atmosphere will remain high until the trough axis clears the area this evening leaving room for some isolated showers across the southeast. As we go into the afternoon, the upstream low level thermal trough will begin to weaken and become less defined, and this will result in decreasing low cloud cover.
Low to mid 50s currently found along and north of I-20 and some cooler 40s still over our southern tier of Counties and Parishes where the clouds are still filtering most of the sunshine. Low temperature records are safe ranging in the low to mid 30s.
239 PM EDT Mon Apr 7 2025 A cold front will slowly progress east across the area through tonight.
1214 PM CDT Mon Apr 7 2025 (Today through Tuesday) Deep South Texas and the Rio Grande Valley, initially under the influence of a zonal mid-level flow, will increasingly be dominated by 500 mb high pressure that will build over the northwest coast of Mexico.
Look for more clear skies, dry air in place, and high temperatures increasing into the lower 70s as the loss of a distinct onshore flow reduces cold advection. Overnight lows should also increase slightly as a result, with inland locations in the upper 40s to low 50s and the coast in the lower 60s.
The object of interest will be the system visible on satellite off to the west, a cold front making its way across the Gulf. A well defined longwave trough will move east across the Southeastern United States and bring the cold front across the Florida Keys tomorrow. The front will be heavily weakened by the Gulf and the low pressure system's separation from the right entrance region of the upper level jet. Forecast soundings depict the wind shear values decreasing to below severe thresholds by the time showers arrive in the Lower Keys with average low level winds below 25 knots. Heavy showers, gusty winds, and thunderstorms are still expected during cold frontal passage.
1240 PM MDT Mon Apr 7 2025 KEY MESSAGES: - Cold front passage today will bring breezy winds, increased clouds and widespread showers.
Clear skies along with light southerly winds will lead to overnight lows in the 30s and a few areas may drop down to near freezing tonight. Tomorrow will be fairly similar to today, other than winds will be out of the south to southwest which will usher in warmer air in the lower levels.
An area of high pressure at 1020mb is located over central TX drifting to the SE toward the coast. In addition, a larger 1024mb high pressure is anchored over the Canadian Prairies, but extends down the middle MS River Valley and is spreading southward. Tuesday our high temps will rebound with the much lighter winds, starting with NW early as the lower atmosphere is still NW flow up to the freezing level. This will boost the day's heating on the wet ground for a run into the lower 70s for most of us.
231 PM EDT Mon Apr 7 2025 - Cooler, and breezy into this evening, with light rain and snow showers possible through the afternoon. - Temperatures back well below freezing into the lower to middle 20s tonight and again Tuesday night.
322 PM CDT Mon Apr 7 2025 Tonight through Tuesday: The upstream low level thermal trough will begin to weaken and become less defined, and this will result in decreasing cold advection and low cloud cover as we go through the near term.
210 PM CDT Mon Apr 7 2025 - Freezing temps likely once again late tonight, prompting the headline to be upgraded to a Freeze Warning.
139 PM CDT Mon Apr 7 2025 - Sub-freezing temperatures are expected again tonight. As a result, another chilly night is in store, with overnight lows in the upper 20s to low 30s, with the higher end of that range (low to mid 30s) towards the MO/AR border. With temperatures below freezing, mostly clear skies, and light winds, conditions are favorable for widespread frost/freeze to occur on sensitive vegetation. The upper level ridge continues building over the region on Tuesday, with surface winds shifting out of the south. With the high pressure remaining in place at the surface, conditions will remain dry through the short term.
Expect another chilly night, although several degrees cooler than what we saw this morning.
1238 PM CDT Mon Apr 7 2025 - Sub-freezing temperatures are expected area wide tonight, posing a risk to susceptible vegetation.
112 PM MST Mon Apr 7 2025 Above normal temperatures will be prevalent throughout this week and into the weekend with high pressure aloft building over the region.
This will usher in a much cooler and drier airmass with temperatures dropping into the 40s and 50s by morning.
139 PM CDT Mon Apr 7 2025 - A widespread freeze will impact sensitive vegetation tonight with the entire region falling below freezing. The entire region remains heavily favored (80-90% chance) to cool below freezing, which will threaten any tender vegetation.
