1154 PM CDT Thu Apr 4 2024 (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.
418 AM EDT Fri Apr 5 2024 A disturbance rotating around a large upper low to the east will pass across the area today. After this moves through, high pressure will build in for the weekend.
348 AM EDT Fri Apr 5 2024 Slow-moving low pressure off the New England coastline will gradually weaken through tonight keeping some rain and nuisance wet snow in place across our region. The latter will produce some minor additional slushy accumulations, with the greatest amounts found across the higher terrain.
(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.
1146 PM CDT Thu Apr 4 2024 (This evening through Friday night) Ridging and high pressure will be building over the area tonight through Saturday morning, suppressing rainfall chances for the next couple of days. As a result, temperatures will feel quite pleasant with highs tomorrow in the mid 70s and lows in the low 50s tomorrow and Saturday mornings.
349 AM CDT Fri Apr 5 2024 - Quiet weather through the start of the weekend with high temperatures by Saturday reaching to the low to mid 50s.
The region is still under the influence of a broad upr trough extending from the NE CONUS and Canadian Maritimes SWWRD into the TN Valley. A deck of low clouds on the SW flank of the trough are moving across the area, but the edge of this cloud deck is slicing roughly NW-SE, and continuing to blanket about the NE half of the area. Northwest to northerly winds will also persist, keeping cooler temperatures in the forecast through the end of the week. Lows in the mid to upper 30s (possibly a few spots in the lower 30s) are anticipated Friday night. Lows Saturday night will be a touch warmer as the aforementioned low pressure system approaches (and moisture increases), with values in the upper 30s to mid 40s.
This will provide modest mixing and aid in temperatures rising into the mid to upper 50s over the eastern CWA to the low to mid 60s west. Those strong winds will allow highs to rise into the low to mid 70 across the western CWA but only into the low to mid 60s across the eastern CWA where winds will not be as strong.
With clear skies, a dry airmass and winds near calm toward sunrise Saturday morning, trended on the cooler side of min temperatures tonight from the low/mid 40s well inland to upper 40s to near 50 along the local Atlantic coast.
Mostly sunny skies and cool temperatures will prevail today with highs in the lower to middle 60s.
952 AM EDT Fri Apr 5 2024 A disturbance rotating around a large upper low to the east will pass across the area today. After this moves through, high pressure will build in for the weekend.
546 AM CDT Fri Apr 5 2024 (Today) A pleasant day is in store across the region today, with mostly clear skies expected underneath modest mid level ridging.
602 AM CDT Fri Apr 5 2024 - Cooler temperatures through this morning.
550 AM CDT Fri Apr 5 2024 (Today and tonight) A narrow, but amplified upper ridge will move west to east across the plains today.
610 AM CDT Fri Apr 5 2024 (Today through Saturday) Key Messages: -Elevated (High chance 80%) fire danger this afternoon in the Brush Country, Rio Grande Plains, the inland portions of the Coastal Bend High pressure continues over south Texas both at the sfc and at 500 mb, today. With the higher humidity, the fire issues should be minimal.
642 AM CDT Fri Apr 5 2024 Mostly sunny skies and cool temperatures will prevail today with highs in the lower to middle 60s.
616 AM CDT Fri Apr 5 2024 - A Freeze Warning and Frost Advisory is in effect for the entire region from 12-8AM Saturday with temperatures falling into the low to mid 30s.
A low pressure system will bring widespread rain showers, snow showers, and isolated thunderstorms to all of southeast Idaho starting later this AM, with showers increasingly mixing with or changing to snow and continuing tonight, Sat, and Sat night as temps cool.
Dry conditions will continue today as an area of high pressure located over the Gulf of Mexico begins shifting eastward towards the peninsula.
(Today and tonight) A cold start to the morning as temperatures have dropped into the lower 40s and upper 30s across the area. The low pressure has pushed inland and is now centered over the central Valley. The difference today is that there is no low pressure system moving through to help trigger the convection. The reason the forecast is challenging today is that there looks to be plenty of sun breaks to warm the surface, but by the late afternoon, the guidance is suggesting the moisture tap will be quite weak after a day of sustained northerly flow behind the low.
603 AM CDT Fri Apr 5 2024 (Today through Saturday Night) Southwesterly flow and sunny skies will contribute to warmer temperatures today as highs reach into the 80s. High pressure aloft will continue off to the east while a tightening pressure gradient at the surface will lead to strengthening onshore winds, courtesy of a low pressure system approaching from the Rockies. Increasing cloud cover will keep highs a touch cooler on Saturday.
Low pressure will continue to produce valley snow and breezy winds through Saturday.
650 AM EDT Fri Apr 5 2024 A disturbance rotating around a large upper low to the east will pass across the area today. After this moves through, high pressure will build in for the weekend.
623 AM EDT Fri Apr 5 2024 Low pressure meanders in the Gulf of Maine through Saturday. This low then slowly exits to the southeast through Saturday night.
Temps will continue at below normal levels with highs generally in the lower/middle 70s. With clear skies, a dry airmass and winds near calm toward sunrise Saturday morning, trended on the cooler side of min temperatures tonight from the low/mid 40s well inland to upper 40s to near 50 along the local Atlantic coast.
(Today and tonight) The upper-level ridging over our area will start to shift off to the east as the upper level low over the west coast pushes towards our area today.
Currently, a pair of deep low pressure systems remain over both the east and west coast CONUS areas. A highly amplified narrow ridge is over the central CONUS. The area is under clear skies with temperatures now in the lower 30s over most locations. Today, high fire danger will set up over portions of north central Kansas areas for a few hours as return flow develops and afternoon winds increase slightly with RH values to the low 20 percent range. Into the Saturday afternoon and early evening time frame, the western CONUS Pacific low pressure system will emerge from the central Rockies. As advection increases and the low pressure system deepens, storms should fire into the afternoon along the cold front and push east across the area.
556 AM CDT Fri Apr 5 2024 (Today and tonight) The upper-level ridging over our area will start to shift off to the east as the upper level low over the west coast pushes towards our area today.
Broad surface ridging extends from Hudson Bay southward into the Deep South this morning.
(Rest of Today) As low pressure continues to shift off the northeast coast today, high pressure will dominate the local area, keeping cooler and drier conditions in place.
The highest forecast rainfall amounts will be along and near the coast Saturday afternoon and evening.
541 AM CDT Fri Apr 5 2024 - Quiet weather through the start of the weekend with high temperatures by Saturday reaching to the low to mid 50s.
609 AM CDT Fri Apr 5 2024 - High pressure remains dominant through Saturday with dry weather.
The cold front that impacted our area yesterday has moved to the California-Arizona border, which lead to a dramatic fall in temperatures, gusty winds, and precipitation for the area.
1247 PM EDT Fri Apr 5 2024 Low pressure meanders in the Gulf of Maine through Saturday. This low then slowly exits to the southeast through Saturday night.
A Pacific cold front will move through the Panhandles during the late morning and early afternoon. Downward motion in association with the cold front combined with the tight pressure gradient will keep these winds close to high wind warning criteria. We will keep the High Wind Watch going for now as there is a little concern that not all areas will actually see high wind criteria. The upper low will pass to our north and will move across northeast Colorado into western Nebraska on Saturday.
Strong negatively tilted upper trough will swing into the central Plains during the day Saturday. Still the potential for a few marginally severe storms during this time period given the low CAPE/high shear environment.
302 PM EDT Fri Apr 5 2024 Low pressure will shift east of the region tonight with high pressure building over the area to start the weekend.
1248 PM CDT Fri Apr 5 2024 - Quiet weather through the start of the weekend with high temperatures by Saturday reaching to the low to mid 50s.
(This evening through Saturday) Our last day for some time of widespread highs in the 80s will be coming to a close thanks to a potent upper low and Pacific cold front poised to reach the forecast area Saturday morning. Until then, lee troughing in eastern NM underneath deep SW flow will keep breezy southerly winds intact overnight with very mild lows to boot. Aloft, the fringes of a negatively-tilted upper trough will be clearing the South Plains during the morning which will carry the strongest 850-700 mb wind cores out of the region before the deepest mixing ensues in the afternoon. Decided to leave the High Wind Watch intact as any slowing of the trough could easily reintroduce higher wind potential, although for now model and ensemble support are stretched thin for a high wind event.
Low temperatures Sat night are expected to average a couple of degrees warmer than tonight, and frost/freeze conditions appear less likely.
1249 PM CDT Fri Apr 5 2024 (Rest of Today) As low pressure continues to shift off the northeast coast today, high pressure will dominate the local area, keeping cooler and drier conditions in place.
Lower clouds will develop late tonight as low level moisture is drawn northward by the deep layer trough advancing into the Rockies. Afternoon wind gusts >35 mph are likely across the eastern half of the forecast area as the low level jet shifts east. The trough moving into the central plains is expected to occlude by Saturday night pushing a weak frontal boundary into the area.
- Sub-freezing temperatures expected for most valleys by early Saturday morning.
(This evening through Saturday) Fire weather, storms, and strong winds are all in the forecast for Saturday as an upper level low treks through the central plains. ***Fire Weather*** The aforementioned winds will combine with RH values in the low teens (and probably a few single digit RHs in our far western counties) to create critical to extreme fire weather conditions in western Oklahoma and adjacent north Texas. Additionally, a weak low level thermal ridge extending northward along and just west of highway 81 will lend its support to fire weather conditions.
Most recent Water Vapor and upper air analysis shows the upper ridge sliding east of the forecast area this afternoon as the upper trough over the west coast moves over the Rockies.
/22 (Now through Saturday) A large Omega Block pattern has set up across the CONUS, resulting in upper-level troughs over the Atlantic and Pacific coasts, and an amplified ridge over the central US. Throughout the period, the ridge will slowly push to the east, eventually moving directly overhead during the day on Saturday. By Saturday, some high clouds will return to the area as the ridge moves overhead and upper winds become zonal, however, with dry, subsident air remaining intact below 500mb, rain continues to remain out of the forecast. Efficient radiational cooling tonight should allow for lows to once again drop into the low to mid 40s inland and upper 40s near the coast.
As of early afternoon, temperatures range from the lower 50s east to the lower 60s west. Overnight lows tonight will be much warmer than previous nights. Attention turns to the approaching upper low for Saturday, initially in the form of a windy day with a strengthening pressure gradient. By late afternoon into the early evening, strong upper ascent and surface convergence along a dryline/Pacific cold front will initiate convection across central into eastern Kansas.
245 PM CDT Fri Apr 5 2024 - Quiet weather for the start of the weekend with high temperatures Saturday reaching to the low to mid 50s.
Temperatures will remain below normal this afternoon with highs in the low to mid 60s. ARS Mostly sunny skies and cool temperatures will prevail today with highs in the lower to middle 60s.

326 PM EDT Fri Apr 5 2024 Low pressure in the Gulf of Maine will continue chances for rain and snow showers through Saturday.
(Through Saturday) A reinforcing cold front moved through the region this afternoon. This will lead to a continuation of cooler and drier conditions tonight into Saturday with lows dipping into the lower to middle 40s and highs reaching into the upper 60s to lower 70s.
pdf A series of dry cold frontal and trough passages through tonight will keep NW winds elevated at 5-10 mph inland and 10-15 mph along the Atlantic Coast and the winds will slowly veer to the North by the early morning hours on Saturday. The next shot of cooler air pushing in tonight under clear skies will push Min Temps down to below normal levels once again, with widespread 40s over inland areas and near 50 degrees along the Atlantic Coast.
135 PM EDT Fri Apr 5 2024 A disturbance rotating around a large upper low to the east will pass across the area today. After this moves through, high pressure will build in for the weekend.
An impressively amplified upper level trough was located over the west coast states this afternoon, while a jet streak and strong mid to low level flow was found downstream across southern Arizona. At the surface, a pressure trough was analyzed through southeastern Arizona, with a shift from southwesterly winds ahead of the axis to west to northwesterly behind it. In the mid-levels, a cold front aloft was analyzed west of the surface feature. Overall precipitation totals should be fairly light ranging from a few hundredths up to around a couple tenths of an inch in the lower elevations and a quarter of an inch to a half inch in the higher elevations of the Catalinas northeast through the Whites, where some light snow will be likely at elevation.
249 PM EDT Fri Apr 5 2024 Large closed low along the New England/Canadian maritimes will continue to churn very slowly over that area through Saturday.
1230 PM CDT Fri Apr 5 2024 - Cooler temperatures through this morning.
Surface analyses place a large cyclone centered near coastal Maine, with a reinforcing cold front working south through Florida.
- Scattered severe storms are possible along a eastward moving cold front Saturday afternoon and evening.
The deep trough that has been forcing our recent active weather period has slid onshore in California and by this evening will begin to move off to the northeast. At the same time a mid-level low pressure has developed over eastern Washington. This mid-level low will eventually move east today and push the cooler air mass over western Idaho into Montana. Then as the cooler air mass moves east, a transition to snow or rain / snow mix will happen.
337 PM EDT Fri Apr 5 2024 A closed low over the Gulf of Maine will maintain snow showers tonight.
220 PM CDT Fri Apr 5 2024 - Low temperatures will drop below freezing tonight.
1240 PM CDT Fri Apr 5 2024 Broad surface ridging extends from Hudson Bay southward into the Deep South this morning.
(Rest of today through Saturday) Dry and comfortable weather conditions are expected through the short-term period across South Florida as an abundantly dry air mass settles in and high pressure build over the area. With mostly clear skies and light NW winds, tonight's lows will range from the low 50s around the interior/Lake Okeechobee region, to the upper 50s to low 60s along the coast.
Temperatures begin to rise and ridging builds in from the west, but temperatures remain about 5 to 10 deg below normal as troughing remains in control one last day. Discussion: Longwave troughing is resulting in cooler and cloudy weather across most of the Eastern US today with northwest flow across our forecast area. Cooler than normal temperatures continue with sct to bkn clouds across the region. While troughing and the lingering cold surface airmass will still heavily influence our weather, temperatures rebound about 10 deg warmer than Friday as ridging begins to expand eastward into our area and sky cover clears with mostly sunny conditions on Saturday afternoon. Any lingering precipitation will exit the higher elevations by Saturday morning with dry weather area-wide.
1200 PM CDT Fri Apr 5 2024 (Today and tonight) The upper-level ridging over our area will start to shift off to the east as the upper level low over the west coast pushes towards our area today.
233 PM CDT Fri Apr 5 2024 - Temperatures at or below freezing tonight may pose a risk to sensitive vegetation across the area. 18z surface analysis showed a large area of high pressure stretching from Lake Superior toward the lower Mississippi River Valley, with a warm front in place from eastern Colorado into northern Texas. High pressure will be the primary driver of our weather over the next 24-36 hours, with continued dry and quiet conditions to start the weekend. our more widespread low-level CU today with drier air more prevalent in the low levels. Winds will be on the increase out of the southeast behind the high, with gusts during the afternoon around 20 MPH.
(Tonight) Temperatures continue to stay on the cooler side this afternoon, currently ranging from the upper 40s to mid 50s. This is about 15-20 degrees below seasonal norms, which are typically in the lower 70s during early April.
1245 PM CDT Fri Apr 5 2024 (Today through Saturday Night) Southwesterly flow and sunny skies will contribute to warmer temperatures today as highs reach into the 80s.
