604 AM EDT Wed Apr 24 2024 High pressure will bring cool and dry conditions today and Thursday. Winds shift to the west behind the front which will allow cooler, drier air to work in from the northwest. Forecast highs only reach into the lower 50s north of I-70 to the middle 60s south of the Ohio River. A Freeze Watch remains in the highlighting areas where temperatures are most likely to drop below freezing. Forecast lows range from the lower to middle 30s areawide.
Slightly warmer temperatures are forecast today, despite the passage of cold front this morning. This front will return north as a warm front tonight, spreading more humid air into the Midsouth that will persist through the weekend.
Afternoon temperatures are on the rise to reach temperatures from the low 80s across the east coast into the mid 80s in the interior and Gulf coast. Tomorrow's conditions will remain relatively unchanged and heavily influenced by high pressure & ridging. Temperatures will be just below seasonal, similar to today, with highs in the low to mid 80s.
The highest rain chcs (60-80%) wl be focused along and north of the warm fnt.
1252 PM EDT Wed Apr 24 2024 High pressure will bring cool and dry conditions today and Thursday. A cold front is now located about halfway through the ILN forecast area. This cooler air aloft is leading to quite a bit of 1000ft-2000ft cloud development, and these clouds are gradually filling in from north to south. Winds shift to the west behind the front which will allow cooler, drier air to work in from the northwest. Forecast highs only reach into the lower 50s north of I-70 to the middle 60s south of the Ohio River. A Freeze Watch remains in the highlighting areas where temperatures are most likely to drop below freezing. Forecast lows range from the lower to middle 30s areawide.

A thermal trough has developed across the Florida Peninsula, which has led to a decrease in winds, most notably in the vicinity of south Florida. Temperatures are in the lower 80s with dew points in the lower 60s. Weak surface anticyclone centered just east of the Sunshine State will wax tonight and wane during Thursday afternoon day as a thermal trough bifurcates it. An upper level ridge will eject out of the Central and Southern Plains and move eastward at the end of the week. At the same time a strong surface anticyclone originating from southern Ontario will spill out across the Atlantic. As this feature drifts further south, it will phase with the upper level ridge, allowing it build.
Dry air in the lower levels of the atmosphere will prove to be a limiting factor in shower/storm coverage this afternoon.

248 PM MDT Wed Apr 24 2024 Temperatures have warmed into the 60s and 70s this afternoon as a ridge axis overhead was slowly shifting east. Lowering heights to the west and an upper low ejecting north and east from the SW US into the central Rockies and plains will allow for additional moisture and energy to advect into the region on Thursday.
Breezy west winds will increase late in the day with the arrival of a cold front.
Temperatures should be a few degrees warmer tomorrow with the continued trend of quiet skies.
(This evening through Thursday) A surface warm front will slowly move towards the north this evening.
At the surface, a high pressure ridge will continue to stretch west-east across our area through Thursday as well.

A warm front will slowly approach the Mid-South from the southwest on Thursday.
(This evening through Thursday) Upper level short wave ridging is in place across the area as an upper level low moves toward the southern California coast. As faster flow moves in aloft maintaining lee troughing, southerly flow continues to keep the air mass in west central Texas moist and unstable. However, with the upper level ridge in place, indicating warmer temperatures aloft, there is some question as to whether or not convection will be able to break the cap.

With temperatures dropping around freezing to sub-freezing for some areas across southwest WI, have issued a frost/freeze headline for tonight through 8 AM Thursday morning. In addition, as we find ourselves in between the departing high and an incoming low pressure system, southeast winds will begin to increase across the region, especially as we head into tomorrow night and through the weekend. Tomorrow Night - Weekend: As has been advertised, an amplified upper level pattern is forecast for the end of the week and weekend as upper level ridging builds to the east and troughing to the west. Overall, precip amounts The aforementioned trough over the southwest U.
-Zanker WEATHER PATTERN OVERVIEW: A ridge off in the Dakotas keeps the region under southwest flow aloft today, leading to calm weather and temperatures as much as 15 to 20 degrees above average.
The clouds are ahead of a weak cold front that is pushing south and will be in central Mississippi this afternoon. Temperatures are not that much cooler behind the front so highs this afternoon will be in the mid to upper 70s. ARS Slightly warmer temperatures are forecast today, despite the passage of cold front this morning. This front will return north as a warm front tonight, spreading more humid air into the Midsouth that will persist through the weekend.
Issued by National Weather Service Cheyenne WY 1133 AM MDT Wed Apr 24 2024 - Scattered showers and thunderstorms are again expected today, mainly for the higher elevations of western and Central Wyoming.

247 PM EDT Wed Apr 24 2024 High pressure over the Great Lakes will bring cool conditions tonight, with dry weather through Thursday.
The presence of the clouds are expected to temper the diurnal curve just a bit and lead to high temperatures in the mid to upper 70s, while full sunshine will send highs into the lower 80s for locations such as Troy and Eufaula this afternoon. In terms of the rain chances today, it appears that the high-res guidance from yesterday was a little too bullish in terms of the rain chances. Upper level heights will begin to rise during the day on Thursday as a 500mb ridge develops over the southwestern Gulf of Mexico. At least isolated showers and storms will be possible during the peak heating of the day with warm temperatures expected in the low to mid 80s.
However, with the ridge upstream building in, this almost backdoor cold front will be just shy of making it into our region. H5 flow will evolve to a more active southwesterly flow as an amplifying upper trough moves east and suppresses the upper ridge down into the Gulf of Mexico.
(Tonight through Thursday night) Mid/upper level ridge over South Texas this afternoon will shift to East Texas on Thursday as next trough advances into the central Rockies.

1218 AM CDT Thu Apr 25 2024 - Frost and freezing temps tonight nw IL.
103 AM CDT Thu Apr 25 2024 (Rest of tonight) A cold front that moved in a north to south manner across the area earlier today, now extended about from the eastern VA/NC, westward across north/central AL, to southern AR. With the airmass change, overnight low temperatures should trend a bit cooler than last night, bottoming out in the mid 40s to near 50 degrees.
Tomorrow will be the start of an overall pattern change as a low pressure system moves onshore of the Pacific NW. Ensemble forecast models continue to indicate a mid-level low circulation developing on the leading edge of a broad trough, that is expected to move across Lemhi County and southwest Montana during the day Friday.
1040 PM CDT Wed Apr 24 2024 (Tonight through Thursday night) Mid/upper level ridge over South Texas this afternoon will shift to East Texas on Thursday as next trough advances into the central Rockies.
(Today) Tranquil weather across the Tennessee Valley early this morning as high pressure continues to promote clear/calm conditions. However, some changes are coming as a deepening mid/upper trough well to the northwest across the central Plains will shift into the Mid- Mississippi/lower Ohio Valley. In response, a warm front will gradually lift NE from central Alabama into the Tennessee Valley by this evening.
(Today through Friday) A cold front, oriented east to west and bisecting the area in half, is slowly pushing southward this morning. Upper level ridging builds into the area tonight and Friday. Continued weak impulses rotating around the ridge will provide lift along the surface boundary for isolated shower and storm coverage overnight and early Friday morning across the northeast.
The short term period should be largely uneventful from a weather standpoint as much of the forcing (both at the surface and aloft) associated with this low will be to the north of our area.
1040 PM CDT Wed Apr 24 2024 (This evening through Thursday) A surface warm front will slowly move towards the north this evening.
(Thursday night through Friday night) Upper-level ridging moves east over the region throughout the short term.
Chambers Temperatures have warmed into the 60s and 70s this afternoon as a ridge axis overhead was slowly shifting east. Lowering heights to the west and an upper low ejecting north and east from the SW US into the central Rockies and plains will allow for additional moisture and energy to advect into the region on Thursday. STP For Friday, a closed low just to the SE of MT will bring precip to SE MT.
109 AM EDT Thu Apr 25 2024 After a strong cold front moved through today, expect cold temperatures tonight with lows in the 20s.
308 AM EDT Thu Apr 25 2024 Today will be dry and sunny, but cooler than normal.
252 AM EDT Thu Apr 25 2024 - Much warmer temperatures this weekend with highs around 80.
208 AM EDT Thu Apr 25 2024 Widespread frost and freeze conditions are expected tonight and Friday morning, with high pressure providing dry and mostly sunny conditions.
The overall synoptic pattern shows ridging over the eastern conus steering southwest flow aloft into our area with an upper low ejecting into the northern plains by Friday morning. Warm air advection will keep us very warm Thursday in the low to mid 70s for highs though increasing cloud cover by the afternoon could limit mixing somewhat. Very unlikely to reach red flag as RH is progged to bottom out on the lower 30s to isolated upper 20s for only a few hours and winds wont be strong enough to compensate (might relocate a few trash cans though). As the upper low near thursday night (still located in eastern CO/western NE/KS) WAA and deformation will allow for increasing precip chances by the late evening though will likely take a few hours of moistening before echos actually begin reaching the surface.
1149 PM CDT Wed Apr 24 2024 (Tonight through Friday night) Broad and slack high pressure is currently in place across SETX and SWLA through the evening as indicated by low-mid level subsidence in this morning's sounding along with a weak vertical wind profile. An overall modifying high pressure regime will keep diurnal temperatures fairly stable over the next several days trending into the mid to upper 80âs for most locations.
230 AM EDT Thu Apr 25 2024 Weak high pressure will build in from the northwest today and provide dry weather for today.
Synoptically, UL ridging will push eastward, allowing southwest flow to dominate into the weekend.
Meanwhile, an upper level ridge gradually dominating over the region before sliding and building along the East Coast. Ridge of high pressure remains in control across the Gulf waters through the period keeping minimal weather concerns. Then, the interaction between the ridge and a disturbance moving north of the area, could bring cautionary level winds to the waters for the weekend. Area of high pressure continues to dominate across fire districts through the next several days.
(Today through Friday) We are going to see great weather today with highs pushing into the low to mid 70s. Skies will start out clear but as the afternoon goes on we will start to see increasing mid to high level clouds ahead of a short wave and warm front. This short wave and warm front will move in Thursday night into Friday morning and will bring the chance for some scattered showers. (Friday Night through next Thursday) Upper level ridging builds in for the weekend with an active pattern setting up to our west. With the active pattern off to our west and high pressure just to our east we will see a good pressure gradient over us bringing breezy winds.
331 AM EDT Thu Apr 25 2024 High pressure will be in control with dry weather Thursday and Friday. Northerly flow allows temperatures to fall below freezing Thursday night.
(Today through Friday) Mid-lvl ridging over the Central US will gradually shift east through the late week period resulting in continued dynamic subsidence and reinforcement of the dry and stable airmass over SFL. At the surface initially weak high pressure over the western Atlantic will prevail today, with the weak gradient favoring a sea-breeze driven wind regime. High temperatures will remain seasonable, ranging from the lower 80s near the east coast to the mid to upper 80s over the west coast/Interior. Given the continued influence of mid-lvl ridging rainfall is once again not expected.
Two low pressure systems will bring widespread rain showers and some thunderstorms. Current conditions/Today: The Northland finds itself caught between the exiting high pressure over the Great Lakes and the encroaching Colorado Low this morning.
419 AM EDT Thu Apr 25 2024 High pressure over the Great Lakes will bring dry weather to the area today. A warming trend will begin by the end of the week, as an upper level ridge moves east of the region, with precipitation chances developing by Friday afternoon.
Discussion: High pressure and associated subsidence has lead to mostly clear skies as noted by surface observations and satellite trends. Upper level heights see minor increases as ridging slowly shifts eastward atop the region Thursday into Thursday night. Lastly, cyclogenesis will take place across central CONUS as a cold front expands from the midwest into Texas. A warm front and southerly H85 flow across the southeast CONUS will result in a slight chance of rain showers early Friday.
1200 AM EDT Thu Apr 25 2024 -Period of near/below freezing temperatures expected early Thursday morning. -Turning much warmer through the remainder of the period.
1234 AM EDT Thu Apr 25 2024 Low pressure will exit across the Maritimes overnight.
The stalled front will lift north as a warm front on Friday with scattered to numerous showers and a few embedded thunderstorms developing across the Mid-South. A warm front will slowly approach the Mid-South from the southwest on Thursday. Once the warm front moves north of the region on Friday, above normal temperatures will prevail through the weekend.
254 AM EDT Thu Apr 25 2024 Weak high pressure will build in today while a front stalls to our south.
A stalled cold front is expected to linger over northern portions of the area throughout the day, bringing isolated showers and thunderstorms possibilities to areas along and north of HWY 82 and northeast MS. Rain chances will begin to diminish for northern areas during the evening hours as the stalled frontal boundary transition into a warm front and lift northward out of the CWA.
Skies are mostly fair with patchy fog beneath, except for SE OK / S AR under clouds riding over the cooler air associated with that weak backdoor frontal boundary from yesterday.
