128 AM EDT Thu Apr 4 2024 A cold front will move offshore this evening and tonight. Chilly high pressure will build into NC from central Canada tonight through Friday. However, there could still be a sprinkle with the passage of the cold front that will be pushing into the RDU/FAY and RWI areas between 800 and 1000 PM this evening. Lows will drop to near seasonal normals tonight, with temperatures in the low to mid-40s.
This will keep Central Alabama within westerly to northwesterly flow pattern, allowing cooler and drier air to advect southward.
High pressure continues over south Texas both at the sfc and at 500 mb, through Friday.
1030 PM CDT Wed Apr 3 2024 - Trending warmer and dry for the rest of the work week.
A cold front will pass southward across Central California this morning. High temperatures this afternoon will be 22 to 24 degrees cooler than yesterday afternoon. In wake of the cold front, an upper-level area of low pressure will settle southeastward over Northern California this afternoon. The cyclone aloft will progress eastward, just north of the service area tonight. The upper-level area of low pressure will open up into a trough of low pressure as it moves eastward over the Great Basin Friday. A trough of low pressure will pass southward across Central California late this weekend.
(Today and tonight) A short wave ridge will move east from Rockies today, with the ridge axis centered over central Texas by this evening. Temperatures will be considerably warmer today, owing to rising heights and a stronger low level thermal ridge. Highs today will be mainly in the low to mid 80s, with lows tonight in the low to mid 50s.
A mid/upper-level low embedded within this trough is expected to shift southeastward, triggering scattered thunderstorm development in western Idaho and west-central Montana. After the thunderstorm threat wanes, focus shifts to precipitation wrapping around the approaching low pressure system.
240 AM CDT Thu Apr 4 2024 - Cooler than average are expected tonight and Friday night.
BREEZY AND COOLER CONDITIONS THROUGH THE END OF THE WEEK. Meanwhile a robust and strengthening cyclone will develop in vicinity of Cape Cop today. Despite cool advection, abundant sunshine will allow temps to warm into the low 70s in NE FL and to the upper 60s in SE GA. Cooler low temps are expected with clear skies and readings will commonly be in the mid 40s inland and in the low 50s at the coast.
- Frost and Freeze headlines across the area tonight into Friday morning as lows fall below freezing.
The higher end of the wind speeds will likely occur across our SW Arkansas and Louisiana zones. Quiet conditions will continue into Friday, but the upper pattern will transition from northwesterly flow to upper ridging. We should also see warmer temps. Morning lows will range from the low to mid 40s in our northern zones to lower 50s south of Interstate 20.
- Lighter winds on Friday with warmer temperatures.
Such is spring in the south! Taking a look around Middle Tennessee at this hour, temps are in the upper 40s and there's still a pretty steady breeze out there which is making it feel cooler than what it is. Highs will be in the low 50s today. Dryer air will continue to filter in as this low moves off to the east.
339 AM EDT Thu Apr 4 2024 A large area of low pressure is centered aloft near the Great Lakes region early this morning, spanning across much of the east coast of the U. The associated cold front continues to move south across the peninsula, with shower activity finished for our local area. Winds will remain rather gusty out of the northwest through the day as a cooler and drier air mass quickly moves in. Highs today will mainly be in the lower 70s to around 80 with much lower humidity.
As this high makes its way a bit further east Friday and Friday night, we'll transition to a more sse flow. Dewpoints will slowly begin an upward climb and we'll see a gradual bump in humidities and warmer overnight lows.
1213 AM CDT Thu Apr 4 2024 - Cooler through Friday with AM temperatures near/below freezing.
- Freezing temperatures possible for a couple hours both tonight and Thursday night into Friday morning.
- Much cooler temperatures tonight into Friday morning.
Friday will trend warmer as high pressure remains over the region.
108 AM CDT Thu Apr 4 2024 - Temperatures are forecast to fall to near freezing tonight and again tomorrow night. The highest chance for a hard freeze is 50-80% tomorrow night. Given steep low level lapse rates again today, some of these showers could be briefly moderate-heavy, though forecast soundings suggest this instability doesn't poke into the DGZ (as it did yesterday), where it'll be quite dry due to subsidence associated with a building ridge of high pressure; thus, the precip should fall as mostly (if not entirely) rain. Temps will thus be warmer across the west where it'll climb into the mid-upper 40s by late afternoon. The dry incoming airmass, however, will allow us to cool off a bit more tonight with forecast lows sub freezing also west of roughly I-57.
159 AM EDT Thu Apr 4 2024 A cold front will bring rain chances to an end from west to east this afternoon and evening. Cooler and drier conditions arrive for Thursday through the weekend as dry high pressure builds in. A cold front is on our doorstep as dewpoints in the 40s and mainly clear skies lie not far to our northwest. Temperatures will be limited by cold advection tonight and subsidence tomorrow as the mid-level trough axis passes overhead, leading to overnight lows in the mid-40s to around 50F and daytime highs in the low-mid 60s. The mid and upper level low pressure system over the northeast will wobble over that region through Friday night.
The lighter winds overnight, along with clear skies, will allow temps to radiate down to just above freezing by Thursday morning across far NE OK into NW AR, with upper 30s elsewhere. A few areas along the KS and Missouri borders may still approach freezing, but the vast majority will not quite reach it.
338 AM EDT Thu Apr 4 2024 (Today through Friday) Yesterday's cold front is currently across central FL and continues to move south. A secondary (dry) front/trough is moving south across the central CWA. High pressure will build in from the SW today while a coastal low moves into New England. Winds: The pressure gradient will be tight today with the strong low to the NE and high pressure building in from the SW. However, near freezing temps are possible in the far NE mtns - but frost formation potential is slightly lower due to clouds/winds.
(Today through Friday) A cold front associated with a strong low pressure system over the Mid-Atlantic will push across the rest of the area this morning, with showers possible along the front over far southeastern areas and the Atlantic waters. By late morning, the front will have cleared the area with northwest winds starting to usher in drier and cooler air across South Florida. Temperatures will be much cooler and more comfortable than yesterday, with highs reaching the upper 70s to around 80. Tonight's lows will range from the low 50s around the interior/Lake O region, to the upper 50s to low 60s along the coast. High temps on Friday will generally be in the low 80s.
(Today) A broad upper level low continues to linger near the Ohio Valley region with dry NNW flow persisting for our area. As the low gradually moves east through the day, upper level ridging begins to expand into the Great Plains.
There is still a 20-30% chance gusts could reach 45 mph, the highest chances west of I-55. - Temperatures are forecast to fall to near freezing each night through Friday night.
Transition to a bit cooler and much drier pattern today. Have therefore sided with higher guidance for temps, and lower guidance for TD's in the low 30s. A few sprinkles are possible this afternoon, especially across the northern half of the forecast area, courtesy of the upper low pushing through the Mid- Atlantic, but no measurable ra is expected.
1111 PM CDT Wed Apr 3 2024 Clouds associated with an upper level low over the Ohio Valley continue to rotate across eastern Missouri into West Tennessee. Clouds should also lift out of the area as the upper level low tracks off to the east. We should see our coldest temperatures of the next 7 days Friday morning when much of the region is expected to dip into the lower to middle 30s.
Meanwhile a robust and strengthening cyclone will develop in vicinity of Cape Cop today. Despite cool advection, abundant sunshine will allow temps to warm into the low 70s in NE FL and to the upper 60s in SE GA. Cooler low temps are expected with clear skies and readings will commonly be in the mid 40s inland and in the low 50s at the coast.
Gusts of 25-35 mph are expected, especially in the higher elevations.
(Today through Friday) Fine weather continues through Friday as amplified 500mb ridge slowly passes overhead.
Although fuels are still moist, the low RH/wind combination will be sufficient for including a limited fire danger threat for today after coordinating with neighboring offices.
635 AM CDT Thu Apr 4 2024 - Cooler than average are expected tonight and Friday night.
642 AM CDT Thu Apr 4 2024 (Today through Friday) Clear skies are intact across all of south central Texas early this morning, with current temperatures ranging from the mid 40s in the Hill Country to the lower 60s along the Rio Grande. A quiet weather pattern will continue through the short term portion of the forecast as mid and upper level ridging builds in from the west.
Temperatures will be cooler today behind the front with mostly clear skies allowing afternoon temperatures to reach the upper 60s for SE GA and lower 70s for NE FL. Meanwhile a robust and strengthening cyclone will develop in vicinity of Cape Cop today. Despite cool advection, abundant sunshine will allow temps to warm into the low 70s in NE FL and to the upper 60s in SE GA. Cooler low temps are expected with clear skies and readings will commonly be in the mid 40s inland and in the low 50s at the coast.
The highest impacts from this wintry system are behind us as the area of low pressure, now offshore along the CA/OR border, shears itself into north and south bodies of energy. As the low center moves onshore rain/snow amounts will become more light and winds will lower, except along ridgetops. Temperatures near or below freezing are expected for most of the area including Jackson and Josephine County. Remember to re-wrap water pipes if you started taking off coverings already as many place sin NorCal and east of the colder spots in Jackson and Joesphine Counties could experience multiple hours of freezing temperatures (sorry folks living east of the Cascades, the low temperature doesn't normally get stay above freezing at night until the end of May or early June).
735 AM EDT Thu Apr 4 2024 (Today through Friday) A cold front associated with a strong low pressure system over the Mid-Atlantic will push across the rest of the area this morning, with showers possible along the front over far southeastern areas and the Atlantic waters. By late morning, the front will have cleared the area with northwest winds starting to usher in drier and cooler air across South Florida. Temperatures will be much cooler and more comfortable than yesterday, with highs reaching the upper 70s to around 80. Tonight's lows will range from the low 50s around the interior/Lake O region, to the upper 50s to low 60s along the coast. High temps on Friday will generally be in the low 80s.
(Today through Friday) Yesterday's cold front is currently across central FL and continues to move south. A secondary (dry) front/trough is moving south across the central CWA.

534 AM CDT Thu Apr 4 2024 (Today) Cooler this morning with temperatures in the lower to mid 40s. Westerly winds will pick up into the afternoon hours, as the trough axis swings southeast through the area. As that trough axis moves through the area early this afternoon, expect mostly cloudy conditions to return north of the Tennessee River and maybe a few showers to occur towards southern middle Tennessee into Jackson county. This cloud cover near and north of the Tennessee River should help to keep temperatures cooler than they could be.
637 AM CDT Thu Apr 4 2024 (Today and tonight) A short wave ridge will move east from Rockies today, with the ridge axis centered over central Texas by this evening. Temperatures will be considerably warmer today, owing to rising heights and a stronger low level thermal ridge. Highs today will be mainly in the low to mid 80s, with lows tonight in the low to mid 50s.
545 AM CDT Thu Apr 4 2024 - Temperatures are forecast to fall to near freezing tonight and again tomorrow night. The highest chance for a hard freeze is 50-80% tomorrow night.

Temps will thus be warmer across the west where it'll climb into the mid-upper 40s by late afternoon. The dry incoming airmass, however, will allow us to cool off a bit more tonight with forecast lows sub freezing also west of roughly I-57.
WEATHER PATTERN OVERVIEW: The strong upper low digging south along the west coast will continue as the main feature driving the weather across the region. Very warm air will continue to be drawn northward ahead of the low, and along with a low level southeast jet, increasing the fire weather concerns for this afternoon through Friday.
614 AM CDT Thu Apr 4 2024 (Today through Friday) Fine weather continues through Friday as amplified 500mb ridge slowly passes overhead.
608 AM CDT Thu Apr 4 2024 (Today) A broad upper level low continues to linger near the Ohio Valley region with dry NNW flow persisting for our area. As the low gradually moves east through the day, upper level ridging begins to expand into the Great Plains.
(Today) Cooler this morning with temperatures in the lower to mid 40s. Westerly winds will pick up into the afternoon hours, as the trough axis swings southeast through the area. As that trough axis moves through the area early this afternoon, expect mostly cloudy conditions to return north of the Tennessee River and maybe a few showers to occur towards southern middle Tennessee into Jackson county. This cloud cover near and north of the Tennessee River should help to keep temperatures cooler than they could be.
(Tonight through Friday night) Key Message: - High confidence in elevated fire weather conditions from inland Kleberg County to Bee County and westward A mid to upper level ridge axis moves across Texas tonight through Friday, leading to mostly clear skies. A deep trough over the western CONUS will shift eastward into the central CONUS heading into the weekend.
Similar to this morning, just about everybody should stay above freezing, but a few localized cold spots could touch freezing along the KS and MO borders. Given limited coverage and low confidence of any freezing temperatures, will hold off on issuing any headlines at this time. (Tonight through Thursday) Southerly winds will resume Friday, advecting warmer air back into the area.
1202 PM CDT Thu Apr 4 2024 (Today and tonight) A short wave ridge will move east from Rockies today, with the ridge axis centered over central Texas by this evening. Temperatures will be considerably warmer today, owing to rising heights and a stronger low level thermal ridge. Highs today will be mainly in the low to mid 80s, with lows tonight in the low to mid 50s.
A cold front from our current big trough slid through this morning bringing strong winds and helped cool our high temperatures by about twenty degrees from yesterday afternoon. This current trough is helping bring moisture, cooler air and strong winds into our area. The cold air from the trough is lowering snow levels and the snow level is expected to drop to about 3,000 feet over the Kern County mountains and about 2,000 feet over the Sierra Nevada.
157 PM EDT Thu Apr 4 2024 Slow moving low pressure just south of the area will continue to bring unsettled weather over our region with rain mixing with and changing to some wet snow. This will especially be the case away from the lakes and across the higher terrain.
A mid-latitude cyclone is working through the Great Lakes Region and into New England as a trailing frontal boundary sweeps south into the Florida Straights, the Bahamas, and the Western Atlantic off the E coast. This is all in association with a deep upper-level low and trough axis stacked in the same region. In the coming days, a strong upper-level ridge will build eastward over the FL peninsula, solidifying the dry and stable pattern. Winds and seas remain elevated in the wake of yesterday's cold front.
weakening area of low pressure will by close to our region tonight and Friday.
(This evening through Friday) Upper ridging, clearly evident on WV imagery, will remain overhead tonight allowing for mild overnight lows in the mid 40s to mid 50s and light surface winds. The upper ridge will be kicked eastward tomorrow/afternoon by a closed upper low moving into California from the Pacific. To add insult to injury, the pressure gradient along the surface lee trough will tighten as the upper low pushes eastward through the day resulting in a breezy day.
1048 AM CDT Thu Apr 4 2024 - Temperatures are forecast to fall to near freezing tonight and again tomorrow night. The highest chance for a hard freeze is 50-80% tomorrow night. Given steep low level lapse rates again today, some of these showers could be briefly moderate-heavy, though forecast soundings suggest this instability doesn't poke into the DGZ (as it did yesterday), where it'll be quite dry due to subsidence associated with a building ridge of high pressure; thus, the precip should fall as mostly (if not entirely) rain. Temps will thus be warmer across the west where it'll climb into the mid-upper 40s by late afternoon. The dry incoming airmass, however, will allow us to cool off a bit more tonight with forecast lows sub freezing also west of roughly I-57.
/SEC (Today through Friday) Yesterday's cold front is currently across central FL and continues to move south. A secondary (dry) front/trough is moving south across the central CWA. High pressure will build in from the SW today while a coastal low moves into New England. Winds: The pressure gradient will be tight today with the strong low to the NE and high pressure building in from the SW. However, near freezing temps are possible in the far NE mtns - but frost formation potential is slightly lower due to clouds/winds.
(Rest of today through Friday) A large stacked low pressure system was centered over Ohio this morning. It will be a little cooler than that Plateau and a little warmer over our southwest counties where more sunshine will be seen. The big low pressure system to our northeast will lessen its control Friday giving us lighter winds and a little more sunshine. (Friday Night through next Thursday) A surface pressure ridge will be directly over the area Friday night, so we expect it to be the coldest night with clearing skies and light winds.
1138 AM CDT Thu Apr 4 2024 (Today through Friday) Fine weather continues through Friday as amplified 500mb ridge slowly passes overhead.
358 PM CDT Thu Apr 4 2024 - Another night of near to below freezing temperatures.
BB/03 (Now through Friday) Zonal to northwesterly flow aloft will be in place through the near term period as our region remains located in between a longwave trough over the eastern US and an amplified ridge building into the central US. As the low lifts away and the high moves closer, the gradient will weaken and winds will begin to relax by tonight and into Friday.
1244 PM CDT Thu Apr 4 2024 - Temperatures are forecast to fall to near freezing tonight and again tomorrow night. The highest chance for a hard freeze is 50-80% tomorrow night. Given steep low level lapse rates again today, some of these showers could be briefly moderate-heavy, though forecast soundings suggest this instability doesn't poke into the DGZ (as it did yesterday), where it'll be quite dry due to subsidence associated with a building ridge of high pressure; thus, the precip should fall as mostly (if not entirely) rain. Temps will thus be warmer across the west where it'll climb into the mid-upper 40s by late afternoon. The dry incoming airmass, however, will allow us to cool off a bit more tonight with forecast lows sub freezing also west of roughly I-57.
329 PM EDT Thu Apr 4 2024 - Late-season is expected over the higher mountains near the Virginia border mainly tonight into Friday evening. During each bout above 2,500 or 3,000 feet) possible, a dusting to an inch may fall, with the highest amounts expected atop Big Black Mountain.
Surface analyses place this morning's cold front over Andros Island, the Cay Sal Bank, and central Cuba. Dewpoints have dipped into the lower 60s in some locations. Thus, a remarkable period of cooler and drier northwesterly breezes will persist across the Keys through the weekend.
Upper low spinning across the area will result in showery conditions, particularly across the mountains at times, where accumulating snow is expected mainly above 2500 feet elevation, along with gusty winds. A winter storm warning is in effect until Friday evening across the higher terrain. In addition, with the upper low overhead, cannot rule out a rumble of thunder this afternoon.
(This evening through Friday) Tonight will be slightly warmer than last night (temperatures in the upper 30s to upper 40s) due to continued warm advection and a slight breeze being maintained overnight. Tomorrow represents the peak of our warming trend for most of the area (highs in the 70s northeast to 80s southwest) as the upper level ridge moves over us.
(This evening through Friday) A benign short-term forecast is on tap for the area as upper level ridging moves overhead this evening and continues through much of tomorrow. As the upper ridge begins to move off to the east late in the day, southwest flow aloft will increase out ahead of the next upper level system in the Western CONUS. Daytime highs will be comparable to today in the low to mid 80s as the high clouds look to limit any significant warm-up from today. Mainly dry weather through the weekend followed by a more By Friday night, a large upper level low will move through the Great Basin into the central/southern Rockies.
- Dry weather will follow for most of the weekend along with near to warmer than normal temperatures.
(Rest of today through Friday) Weather conditions have begun to improve this afternoon behind the passage of a weak cold front. With the front now well to our south, generally northwesterly winds will advect cooler and drier air over the area allowing for more comfortable sensible weather through the short term. High temperatures today will reach the upper 70s to around 80, while lows overnight will range from the low 50s around the interior/Lake O region, to the upper 50s to low 60s along the coast. High temps on Friday will generally be in the low 80s.
With cold air advection easing, high temperatures Friday will be just a touch warmer with slowly decreasing clouds very late in the day.
Issued 1010 AM CDT Thu Apr 4 2024 Light to moderate snowfall currently overspreads the CWA, with accumulations limited due to surface temps at or slightly above freezing.
1246 PM CDT Thu Apr 4 2024 - Cooler than average are expected tonight and Friday night.
Temperatures dip to a seasonably cool range of upper 30s F around the Golden Triangle to the lower 40s F elsewhere. Some lower-end chance will exist for patchy frost on elevated, cool surfaces (like unprotected car windshields) in those typically cooler locales that make a run for the 36-37 F range.
