WEATHER PATTERN OVERVIEW: The upper trough moving into the Pacific Northwest will slide east today and flatten out. Slightly cooler temperatures, especially in the west, even with low relative humidity may create elevated concerns for a time but not for widespread or prolonged enough exposure to merit issuing headlines at this time. Upper ridging will resume warm and dry conditions over the region late week before the next rough arrives for the weekend.
614 AM CDT Tue Apr 8 2025 - Freezing temperatures early this morning area wide.
Trough axis will swing through the region during the course of the day. Meanwhile, high pressure at the surface centered to our north northwest this morning will continue to slide east of the CWA. This will result in a rather pleasant day across the forecast area today, as highs range from the middle 60s north to the lower 70s south, under sunny skies.
629 AM CDT Tue Apr 8 2025 (Today through Wednesday) - Elevated to Critical Fire Weather conditions today (See Fire Weather Discussion for more information) Quiet and dry conditions will persist through midweek as ridge continues to meander eastwards.
A weak system will bring a mainly dry cold front through the region, dampening the warming trend through Wednesday across northern Utah.
917 AM EDT Tue Apr 8 2025 A cold front will cross the area this morning, leading in much colder air. High pressure and dry weather follow for tonight and Wednesday.
134 PM EDT Tue Apr 8 2025 Chilly and dry conditions continue as high pressure builds into the region tonight. Temperatures will be a bit warmer, but still remain below average for the time of year. Mostly sunny skies will continue today as high pressure builds in from the Upper Midwest. High temperatures will be held in the 40s due to the cold air mass associated with the high.
- Conditions forecast to warm during the remainder of the work week until another cold frontal system moves through at the end of the week.
(Through Wednesday) Benign and pleasant conditions are expected through tomorrow as cooler and drier air continues to move in from the north following yesterday's cold front.
- A ridge of high pressure builds tomorrow through the end of the week causing mild, warm weather. - A lot of uncertainty remains for the weekend system, but it will be cooler with some snow. In the mountains, the showers will be snow showers due to the higher elevation and timing, whereas in the valleys warmer temperatures will keep the showers a rain snow mix with no accumulation expected.
250 PM EDT Tue Apr 8 2025 High pressure moving over the mid-Atlantic states tonight will bring below freezing conditions for much of central North Carolina.
Generally clear skies will persist as high pressure settles in across our south through the afternoon and evening. Similar conditions can be expected tomorrow, with temperatures warming further into the low to upper 80s. Temperatures will also be influenced by compressional warming ahead of a weak cold front that will be sliding through Oklahoma starting tomorrow evening. Overnight lows both tonight and tomorrow night will range in the low to upper 50s for both North and Central Texas.
Upper ridge continues from the Northern Plains into the southern Prairie provinces of Canada, but water vapor loop shows a fairly vigorous trough moving through eastern MT. Some of the model solutions have some snow and freezing rain mixing in across northwestern MN, but probabilities are 20 percent or less.
(Tonight through Wednesday night) Current surface observations/analysis show a lee-side trough in place across the plains of eastern New Mexico southward into west Texas. For tonight, the surface pressure pattern changes little, with low pressure to the north and high pressure to the east and southeast. This will lead to southerly winds in the lower levels across south central Texas, with some breezy conditions expected across the higher terrain of the Hill Country and southern Edwards Plateau. Winds over the higher terrain of the Hill Country and southern Edwards Plateau could remain gusty through the evening hours.
100 PM CDT Tue Apr 8 2025 - Gusty southwest winds of 25 to 35 mph on Wednesday, with a return of warmer temperatures into the upper 60s to lower 70s.
Surface chart currently depicts low centered over the MT/ND border with warm frontal boundary running south into western SD this afternoon. Trailing cold front stretches from southeastern MT down into central WY. Areas of showers expected to increase over the afternoon and evening as cold front crosses the region. Forecast QPF amounts have dropped somewhat, given limited moisture with dewpoints in the low 30s. Cooler temperatures are in store for Wednesday, with highs in the 50s to mid 60s.
427 PM EDT Tue Apr 8 2025 Low pressure crosses the area tonight, exiting early tomorrow morning.
358 PM EDT Tue Apr 8 2025 Cool and dry conditions will continue tonight as high pressure builds into the region.
(Rest of today and tonight) A benign weather pattern continues through the near-term period thanks to a large-scale trough over the eastern Hudson Bay and a large-scale ridge over the subtropical Pacific. The presence of modest moisture and mechanical mixing will keep lows in the low 50s.
- Small precipitation chances expected midweek, then drier and warmer weather expected for the end of the week. High pressure conditions will retreat eastwards overnight as warm air advection aloft increases and mid to high clouds move in.
By Wednesday, high pressure begins to build over the Gulf pushing slightly drier and cooler air (at least for a second) with afternoon temperatures warm up a degree or two but dry air will make conditions feel very comfortable.
The region remain under a dry northwesterly flow aloft being on the western side of the broad scale trough over the eastern U. At the surface, high pressure is spreading into the region from the west.
346 PM EDT Tue Apr 8 2025 - Snow/Rain on Wednesday Lake effect snow flurries will end this evening as general subsidence and drying continues with upper troughing moving east in advance of a clipper low. The low center tracks across southern Lower Michigan during Wednesday with an area of mid level frontogenetical forcing resulting in mesoscale bands of heavier snow centered across the southern half of the forecast area. Precip rates could be heavy enough to result in a coating of wet snow on pavement by late morning but impacts to travel should be minor as sfc temps rise above freezing. The precip winds down during the evening as the low moves east and the f-gen forcing weakens.
Northwesterly flow will remain overhead as an upper trough over the gulf moves east and a upper ridge begins to build over the western CONUS. A lee side low will develop and track over northeastern portions of the region pushing a weak and dry cold front through late morning to early afternoon.
112 PM EDT Tue Apr 8 2025 High pressure and dry weather will continue into Wednesday.
Updated at 246 PM CDT TUE APR 8 2025 - Freezing conditions are expected for the northern half of Central Alabama Wednesday morning, while all other locations will at least observe patchy or areas of frost as temperatures drop into the upper 20s in the far north to mid 30s in the south. (This evening through Wednesday) NW winds this afternoon behind a reinforcing cold front should taper down during the evening hours becoming light/variable to near calm for the late night/pre-dawn hours and into the day on Wednesday. Surface ridging will settle in over E Conus this afternoon with gradients relaxing. The ridge should slowly drift toward the E Coast through the short term.
217 PM EDT Tue Apr 8 2025 (Today and tonight) Cooler today with the passage of the cold front with highs generally in the lower to middle 70s, which is slightly cooler than average.
Hope everyone is out and about enjoying this nice day! After temperatures reaching well into the 70s today, we will be a few degrees warmer for tomorrow. High temperatures tomorrow will reach the lower 80s in many locations across the Panhandles. A weak cold front will come through the area tomorrow which will shift winds to northerly by the second half of the day.
A large upper level ridge over the Desert Southwest will steer northwest flow into the ArkLaTex.
Upper riding is suggestive of warm and dry conditions late this week before ensembles show a pattern shift for the weekend with cooler and wetter conditions - potentially with widespread wetting rains as the next western trough sets up.
A low cloud deck may squeak by overnight underneath high-pressure with a low, but with weak forcing, additional impactful snow chances with this seem unlikely. With calming winds, generally clearing skies, and cold low- levels, low temperatures are expected to fall about ten degrees below normal, with a >95% chance of sub-freezing lows. ------------------------------------------------------------------- As low clouds nearly clear into Wednesday, the day will begin with mostly clear skies and calm winds under high pressure. Into tomorrow night, a deepening 500mb trough will enhance surface convergence along the inflection point of the upper jet, resulting in increasing precipitation chances.
259 PM EDT Tue Apr 8 2025 - Rivers have already reached or are expected to reach moderate to major flood stage in Central and South Central Indiana, primarily in the White and East Fork White River basins - Widespread, significant river flooding continuing through at least the next 1 to 2 weeks in some spots - Freezing temperatures again tonight - Rain arrives on Wednesday, amounts expected to be light and generally under a half inch - Warming trend this weekend. This, combined with light winds and a dry atmosphere, will lead to temperatures falling into the upper 20s to the lower 30s for lows. Western areas may see freezing readings earlier in the night then warm some early in the morning. At the surface, a warm front will move in from the southwest during the day.
251 PM EDT Tue Apr 8 2025 High pressure and dry weather will continue into Wednesday.
1151 AM CDT Tue Apr 8 2025 - Freezing temperatures early this morning area wide.
1151 AM CDT Tue Apr 8 2025 (Today through Wednesday) - Elevated to Critical Fire Weather conditions today (See Fire Weather Discussion for more information) Quiet and dry conditions will persist through midweek as ridge continues to meander eastwards.
Aloft, northwesterly flow associated with an upper-level trough over the eastern CONUS and a pronounced ridge across the west will maintain dry conditions and clear skies across the area. Meanwhile, daytime highs will warn quickly from slightly below normal today to near-normal values by Wednesday, ranging from the low 80s to low 90s.
Little to no impact from the snow is expected given temperatures above freezing.
(Tonight through Wednesday night) Through Wednesday high pressure aloft and at the surface maintains our pleasant quiet weather pattern. The building mid/upper level ridge to our west allows for a slight increase in temperatures under a persistent dry atmosphere maintaining comfortable conditions. Lows tonight/Wednesday morning although a few degrees warmer than the last few mornings, minimums drop well into the 50s.
110 PM CDT Tue Apr 8 2025 Updated at 1224 PM CDT TUE APR 8 2025 - Freezing conditions are expected for the northern half of Central Alabama Wednesday morning, while all other locations will at least observe patchy or areas of frost as temperatures drop into the upper 20s in the far north to mid 30s in the south. Otherwise high pressure sets up shop for the short term and keeps our area on the cool side through Wednesday. At this time feel confident enough to go ahead with the cooler temperatures based on impacts this time of the year.
257 PM EDT Tue Apr 8 2025 High pressure builds in from the west for the middle of this week with another frontal system late week. High pressure then builds in again for the weekend. High pressure will continue to build in overnight with upper trough pushing off the east coast. Went below guidance for lows, generally falling into the low to mid 30s inland and upper 30s to mid 40s for the beaches. Cool high pressure will continue to build over the area as flow becomes more zonal aloft across the Carolinas.
Updated at 125 PM CDT TUE APR 8 2025 - Freezing conditions are expected for the northern half of Central Alabama Wednesday morning, while all other locations will at least observe patchy or areas of frost as temperatures drop into the upper 20s in the far north to mid 30s in the south. (This evening through Wednesday) NW winds this afternoon behind a reinforcing cold front should taper down during the evening hours becoming light/variable to near calm for the late night/pre-dawn hours and into the day on Wednesday. Surface ridging will settle in over E Conus this afternoon with gradients relaxing. The ridge should slowly drift toward the E Coast through the short term.
A cold front has pushed south of the forecast area, but over- running behind the front is creating an area of cloudiness across west central and southwest Florida this evening. As the front continues to move away from the region, much cooler drier air will advect across the forecast area with skies clearing overnight from north to south. By Wednesday, high pressure begins to build over the Gulf pushing slightly drier and cooler air (at least for a second) with afternoon temperatures warm up a degree or two but dry air will make conditions feel very comfortable.
1000 PM EDT Tue Apr 8 2025 Cool and dry conditions will continue tonight as high pressure builds into the region.
725 PM EDT Tue Apr 8 2025 - Snow/Rain on Wednesday Lake effect snow flurries will end this evening as general subsidence and drying continues with upper troughing moving east in advance of a clipper low. The low center tracks across southern Lower Michigan during Wednesday with an area of mid level frontogenetical forcing resulting in mesoscale bands of heavier snow centered across the southern half of the forecast area. Precip rates could be heavy enough to result in a coating of wet snow on pavement by late morning but impacts to travel should be minor as sfc temps rise above freezing. The precip winds down during the evening as the low moves east and the f-gen forcing weakens.
624 PM CDT Tue Apr 8 2025 Updated at 555 PM CDT TUE APR 8 2025 - Freezing conditions are expected for the northern half of Central Alabama Wednesday morning, while all other locations will at least observe patchy or areas of frost as temperatures drop into the upper 20s in the far north to mid 30s in the south.

Surface ridging will settle in over E Conus this afternoon with gradients relaxing. The ridge should slowly drift toward the E Coast through the short term.
735 PM EDT Tue Apr 8 2025 High pressure moving over the mid Atlantic states tonight will bring cold conditions to central North Carolina.
/NEW/ /Through Wednesday Afternoon/ Surface observations show a sprawling area of high pressure over the Midwest, which has allowed southerly flow to return across North and Central Texas this afternoon.
1001 PM EDT Tue Apr 8 2025 High pressure moving over the mid Atlantic states tonight will bring cold conditions to central North Carolina.
A warming and drying trend will begin Wednesday as an upper- level ridge builds over the Intermountain West.
741 PM EDT Tue Apr 8 2025 - Rivers have already reached or are expected to reach moderate to major flood stage in Central and South Central Indiana, primarily in the White and East Fork White River basins - Widespread, significant river flooding continuing through at least the next 1 to 2 weeks in some spots - Freezing temperatures again tonight - Rain arrives on Wednesday, amounts expected to be light and generally under a half inch - Warming trend this weekend. This, combined with light winds and a dry atmosphere, will lead to temperatures falling into the upper 20s to the lower 30s for lows. Western areas may see freezing readings earlier in the night then warm some early in the morning. At the surface, a warm front will move in from the southwest during the day.
Mountain snow showers will continue in the Sawtooths/Central Mountains through the evening courtesy of an upper level trough to our north bringing a bit of moisture through to us, but any additional snow will be light, around an inch or so as snow levels are around 6500 feet. Highs today will be about 5 degrees cooler than yesterday, but still in the 50s and low 60s for most. Winds will be a bit breezy on ridge tops tomorrow, gusting to around 30 mph, but the rest of us will see more "typical" afternoon wind gusts around 20 to 25 mph.
747 PM EDT Tue Apr 8 2025 High pressure and dry weather will continue into Wednesday.
Dry weather is likely this evening through Wednesday night as upper ridging builds into the area.
612 PM CDT Tue Apr 8 2025 (Tonight through Wednesday night) Through Wednesday high pressure aloft and at the surface maintains our pleasant quiet weather pattern. The building mid/upper level ridge to our west allows for a slight increase in temperatures under a persistent dry atmosphere maintaining comfortable conditions. Lows tonight/Wednesday morning although a few degrees warmer than the last few mornings, minimums drop well into the 50s.
A prefrontal trough is swinging eastward through the Keys this evening. High pressure is building in from the west. This along with the prefrontal trough is resulting in a tightening pressure gradient and strengthening northwest breezes. Expect winds to shift more northwest to north and strengthen further over the next few hours as the gradient tightened between the Gulf high and the trough over the Bahamas. It will be a while longer before the prefrontal trough clears our area. Expect the warmest lows in the Lower and Middle Keys and coolest in the Upper Keys. A prefrontal trough will steadily swing eastward of our waters through the overnight period. High pressure will slowly build eastward into our area and result in a tight pressure gradient.
547 PM CDT Tue Apr 8 2025 - Gusty southwest winds of 25 to 35 mph on Wednesday, with a return of warmer temperatures into the upper 60s to lower 70s.
645 PM CDT Tue Apr 8 2025 (Tonight through Wednesday night) Current surface observations/analysis show a lee-side trough in place across the plains of eastern New Mexico southward into west Texas. For tonight, the surface pressure pattern changes little, with low pressure to the north and high pressure to the east and southeast. This will lead to southerly winds in the lower levels across south central Texas, with some breezy conditions expected across the higher terrain of the Hill Country and southern Edwards Plateau. Winds over the higher terrain of the Hill Country and southern Edwards Plateau could remain gusty through the evening hours.
716 PM EDT Tue Apr 8 2025 Cool and dry conditions will continue tonight as high pressure builds into the region.
724 PM EDT Tue Apr 8 2025 (Through Wednesday) Benign and pleasant conditions are expected through tomorrow as cooler and drier air continues to move in from the north following yesterday's cold front.
Lake effect snow flurries will end this evening as general subsidence and drying continues with upper troughing moving east in advance of a clipper low. The low center tracks across southern Lower Michigan during Wednesday with an area of mid level frontogenetical forcing resulting in mesoscale bands of heavier snow centered across the southern half of the forecast area. Precip rates could be heavy enough to result in a coating of wet snow on pavement by late morning but impacts to travel should be minor as sfc temps rise above freezing. The precip winds down during the evening as the low moves east and the f-gen forcing weakens.
917 PM CDT Tue Apr 8 2025 The influence of high pressure continues this evening as the local SHV ASOS suggests calm winds, while satellite advertises clear skies, a signal that radiational cooling will support cooler overnight lows, even with the return of some light southerlies through the early AM hours. A large upper level ridge over the Desert Southwest will steer northwest flow into the ArkLaTex.
High pressure will continue to ridge across the CWA from the northeast while northwest flow aloft remains over the region.
1034 PM EDT Tue Apr 8 2025 Light breeze this evening has kept temperatures running a couple degrees warmer than forecast, so made slight changes.
800 PM MDT Tue Apr 8 2025 - Breezy conditions Wednesday, gusts 25-45 mph in the lower elevations.
1235 AM CDT Wed Apr 9 2025 (Tonight through Wednesday night) Through Wednesday high pressure aloft and at the surface maintains our pleasant quiet weather pattern. The building mid/upper level ridge to our west allows for a slight increase in temperatures under a persistent dry atmosphere maintaining comfortable conditions. Lows tonight/Wednesday morning although a few degrees warmer than the last few mornings, minimums drop well into the 50s.
(Today) A clear, cold morning across the Tennessee Valley, with 07z temperatures in the low to mid 30s across the region -- with a drop of an additional 3-4 degrees likely before sunrise. With high pressure controlling our sensible weather across the area, expect clear/sunny conditions to continue.
Sunny this afternoon with warmer, near normal temperatures. This will result in warmer temperatures today near normal. With increasing mid to high level clouds and southerly flow, temperatures tonight will be warmer across the region with no risk of frost into Thursday morning. Showers and thunderstorms, some severe with large hail, possible Thursday afternoon ahead of a cold front.
1215 AM CDT Wed Apr 9 2025 Updated at 1213 AM CDT WED APR 9 2025 - Freezing conditions are expected for the northern half of Central Alabama Wednesday morning, while all other locations will at least observe patchy or areas of frost as temperatures drop to near 30 degrees in the far north to mid 30s in the south. (This evening through Wednesday) NW winds this afternoon behind a reinforcing cold front should taper down during the evening hours becoming light/variable to near calm for the late night/pre-dawn hours and into the day on Wednesday. Surface ridging will settle in over E Conus this afternoon with gradients relaxing. The ridge should slowly drift toward the E Coast through the short term.
258 AM EDT Wed 9 2025 High pressure will shift offshore today and tonight allowing for moderating temperatures and dry conditions.
- Conditions forecast to warm during the remainder of the work week until another cold frontal system moves through at the end of the week. (Tonight through Thursday night) High pressure continues to build over the Southern Plains and the Western Gulf Coast. While continued ridging is expected to keep conditions clear and dry across SETX / SWLA, a dry cold frontal boundary from the aforementioned system will laydown across the ARKLATEX region.
1232 AM EDT Wed Apr 9 2025 - High pressure dominates the forecast through much of this week and into the upcoming weekend, though a system passing south of the region Wednesday/Thursday will introduce a low chance (15-35%) for rain/snow showers. The quiet short term period continues across Upper Michigan with high pressure in place over the region per latest surface analysis/water vapor imagery. The upper air pattern the rest of the week through the weekend features deeply anomalous cutoff lows over eastern Canada and the Gulf of Alaska, separated by a tall ridge that extends from WY/MT all the way to northern Nunavut.
High temperatures in the lower 90s west and 80s elsewhere today will warm a few degrees tomorrow with mid and possibly upper 90s along the Rio Grande.
For the later half of the week and into the weekend, upper-level ridging will build east into the area. This will lead to warmer and dry conditions.
(Today and tonight) High pressure will dominate the weather today with light winds and abundant sunshine.
