(Today and tonight) Upper level ridging remains in control of the weather for this afternoon. Like the last two days, a gradient in deep-layer moisture will be in place across the forecast area with the highest moisture content across our Florida Panhandle counties with lesser amounts across our southwest Georgia counties.
229 AM MDT Fri Aug 30 2024 Ridging builds over the area today for sunny skies and warmer temperatures through the weekend.
908 PM MDT Thu Aug 29 2024 Drier and warmer conditions will continue through the rest of the weekend as an upper level ridge builds over the region. -Casey 30/00Z Very little to report in the aviation forecast with a ridge of high pressure rolling overhead, providing generally quiet skies and relatively light winds.
Drier and warmer conditions will continue through the rest of the weekend as an upper level ridge builds over the region. -Casey 30/06Z TAF Period VFR conditions will prevail across all terminals with few to no clouds due to an upper-level ridge building in over North-central, Central, and Southwestern Montana.
149 AM EDT Fri Aug 30 2024 A warm front will lift north across the area tonight, followed by a cold front Friday night.
* Cold front will move through the region late this weekend, bringing relief from hot temperatures and humidity. Temperatures across the region varied from the mid-upper 70s in areas that received rainfall this afternoon, to the the lower 80s in the I-65 corridor and points west. Expect to see isolated to widely scattered showers and storms develop by afternoon into the evening, most notably along and west of I-65 as the upper ridge begins to break down a bit.
- Most areas will be cooler today with highs around 80.
North and Central Texas will remain in an area of weak low pressure, sandwiched between a ridge centered near the Great Basin and one across the southeastern states. 75), the arrival of a weak cold front from the northwest, and the sea-breeze front from the southeast will result in scattered to numerous showers and storms. Temperatures through Friday night will be very tolerable for late August with lows generally in the lower and middle 70s and highs in the mid 80s across the southeast and lower/middle 90s elsewhere.
Isolated to scattered showers and thunderstorms today, becoming more widespread through the weekend, especially over the higher terrain.
Strong high pressure for this time of year has built over much of the western U. However the lack of upper level winds and stable conditions under the ridge is a favorable set up for or hazy or smoky conditions, given smoke from nearby wildfires across central Idaho and the Bitterroots.
302 AM CDT Fri Aug 30 2024 - Showers and thunderstorms winding down this morning, a few showers lingering post-frontally into midday in the south, then high pressure takes over behind passing cool front by tonight. Continuing LLJ will fuel scattered showers and thunderstorms into the morning, but diurnally decrease as LLJ gets interrupted and incoming ridge/cool front take over as the late morning and afternoon progresses. Cooler low temps in the mid to upper 50s into early Sat morning.
Chance to likely PoPs are in place for a good chunk of the FA this afternoon, with the highest chances generally occurring along the I-44 corridor near the front. Temperatures today will be much cooler as a result of the increased cloud cover and precipitation.
143 AM MDT Fri Aug 30 2024 - Another taste of fall this morning with chilly temperatures near or sub freezing across western WY. East of the Divide will see highs range from the low to mid 80s with values west of the Divide reaching the mid to upper 70s. A potent area of high pressure builds into the western CONUS today. This high will keep warm and dry conditions over the CWA through the weekend. This low would bring chances for precipitation to other parts of the CWA but confidence is currently low at this time. Some models are starting to indicate the possibility for some widespread precipitation as a result of this low.
1137 PM EDT Thu Aug 29 2024 High pressure will move slowly east of the area overnight and Friday.
Updated at 252 AM CDT Fri Aug 30 2024 - Widespread showers/storms expected behind a cold front that is expected to move into the area starting this evening. (Today and tonight) The trough digging through the main upper jet across the Northern Plains through the Upper Midwest Regions will continue to push a cold front across northwest Oklahoma reaching the I-44 corridor by noontime. As the mid-levels quickly moisten up with the lower-levels at a slower rate, convergence above the front with isentropic ascent into the mid-levels will continue to produce rain showers. Will have the highest rain POPs across western and northern into portions of central Oklahoma through this morning. Although surface based CAPE's in the lower-end moderate range, weak shear DCAPE values suggest storms should stay below severe, although isolated storms could be a bit more numerous in the afternoon.
308 AM EDT Fri Aug 30 2024 A warm front will lift north across the area tonight, followed by a cold front Friday night.
Forecast updates included lowering chances of precipitation inland this evening as activity ended, but kept the high chances after Midnight into Friday morning.
Early morning surface observations capture the position of a cold front, positioned from roughly New Richmond to the southwest towards Albert Lea at this hour. The departure of the cold front will signal the end of the recent active weather pattern that brought multiple rounds of severe weather to the Upper Midwest and will open the door for a gorgeous weekend ahead. The combination of afternoon highs in the upper 70s and dew points in the low to mid 50s will make for a much more comfortable feel as compared to the recent trend of Summer heat and humidity.
257 AM CDT Fri Aug 30 2024 - Below normal temperatures for today and tomorrow - Rain ending during the day today and into the afternoon - Cooler temperatures will prevail through the forecast period A rather strong cold front is moving through the region this morning which has brought a wide area of light rain and embedded thunderstorm activity. Temperatures behind this front are a decent amount cooler.
956 PM MDT Thu Aug 29 2024 - High pressure moves across Wyoming for the Labor Day holiday weekend, leading to warmer, above normal temperatures.
307 AM CDT Fri Aug 30 2024 - Below normal temperatures for today and tomorrow - Rain ending during the day today and into the afternoon - Cooler temperatures will prevail through the forecast period A rather strong cold front is moving through the region this morning which has brought a wide area of light rain and embedded thunderstorm activity.

00Z model suite continues to show the upper level ridge that has brought us the record heat over the past few days will slowly weaken today and shift to our south, while low level moisture continues to slowly increase.
215 AM MDT Fri Aug 30 2024 Ridging builds over the area today for sunny skies and warmer temperatures through the weekend.
- Cooler temperatures will continue through the weekend and the start of next work week (70s and 80s).
A wetter and cooler pattern has arrived across the Midsouth.
- Cooler temperatures expected for the Labor Day weekend. This feature along with trailing energy on the backside of the trough had brought a surface front across much of Kansas and as of 07Z it was located from north central Missouri across southeast Kansas. The precipitation is expected to gradually shift to the southwest through sunrise this morning as high pressure moves in the from the west and northwest.
1058 PM CDT Thu Aug 29 2024 Updated at 1032 PM CDT Thu Aug 29 2024 - Widespread showers/storms expected behind a cold front that is expected to move into the area starting this evening. An attendant cold front, which is draped from southeastern CO to the Northern Plains, is expected to make a push southward this evening. High temperatures tomorrow will be in the low to mid 80s behind the front, and low 90s ahead of the front.
Latest models are a bit less "messy" in this morning than previous runs, extending the lull in convection until at least early this afternoon as an upper trough approaches from the west. Given this cloudy/showery pattern, highs will struggle to reach much into the 80s on the Caprock, however will be slightly warmer off the Caprock with precipitation taking slightly longer to get there.
1104 PM CDT Thu Aug 29 2024 Updated aviation portion for 06Z TAF issuance - Showers and thunderstorms into Friday morning from a cold frontal passage.
1143 PM MDT Thu Aug 29 2024 - A few weak showers/storms over the higher terrain with gusty winds and brief light/moderate rain through this evening.
Broad ridging remains dominant, but a compact upper-level low is also spinning off the FL East Coast. With the ridge axis to the east, an easterly flow continues in the background. With the low in close proximity, there is a slight tightening of the gradient. However, there is a notable drying in the mid-levels, with the low also dragging more dry air down over the Florida peninsula. The deepest moisture will reside in SWFL (thus the highest POPs) and the least resides over the Nature Coast (thus the lowest POPs). The subtropical ridge will slide further east, eventually veering the flow more towards and ESE direction.
Look for the possibility of convective redevelopment after midnight, towards sunrise Friday morning across our far southern zones given the proximity of the anchored upper level trough with more scattered to numerous showers and thunderstorms developing by late morning and especially during the afternoon on Friday with the aid of daytime heating.
226 AM MDT Fri Aug 30 2024 Ridging builds over the area today for sunny skies and warmer temperatures through the weekend.
626 AM CDT Fri Aug 30 2024 - Showers and thunderstorms winding down this morning, a few showers lingering post-frontally into midday in the south, then high pressure takes over behind passing cool front by tonight.
(Now through Saturday night) A mid/upper ridge will continue over the region into the weekend before breaking down Saturday night as a upper trough sets up over the eastern CONUS.
After that, ridging takes over in the UL through mid-week. Highs in the 70s throughout the week, possibly low 80s at the height of the ridge's strength mid-week, and lows in the 50s and 60s.
626 AM CDT Fri Aug 30 2024 (Today through Saturday) Key Messages: - Medium chance for showers and storms today; slightly higher Saturday A less active day continues to be expected today as the mid level low pressure continues to gradually move away from the region.
Showers and thunderstorms expected to spread across West An upper-level trough and associated weak surface cold front will track into West Central Texas today from north to south through tonight. The front will bring scattered to numerous showers and thunderstorms during the afternoon and evening hours, with the higher rain chances across the northern half of the area. Overnight low temperatures into Saturday morning will remain in the low to mid 70s.
Warm and dry weather is expected over the weekend as upper level ridging builds in across the region, with highs in the 80s to low 90s at times.
A mid/upper level low pressure system meandering just offshore of Southeast Texas, will slowly wobble east northeast and eventually over Louisiana through tonight, weakening in the process. This low, combined with increasing moisture/instability and warm temperatures across the CWA this afternoon (highs from the mid 80s to mid 90s), will result in another bout of scattered to widespread showers and scattered thunderstorms lifting north northwest through the forecast area. However, some stray showers can't be ruled out during the overnight hours and into early Saturday morning as lows fall into the low to mid 70s.
1024 AM EDT Fri Aug 30 2024 A warm front will lift north across the area this morning, followed by a cold front tonight into Saturday morning.
Dry today with temperatures trending warmer. Clear skies across the region early this morning as high pressure remains parked over the Great Basin region. Highs this afternoon trend warmer by a couple to a few degrees, with temperatures ranging from mid 80s to low 90s. Low pressure approaching the northern CA coast tonight into Saturday will help to advect increasing amounts of mid-level moisture up into central NV on Saturday. There should be enough moisture lift and instability for a handful of lightning strikes south of the Highway 50 corridor Saturday afternoon and early evening.
The largely Pacific moisture-driven system will have most of its precipitation close to the low over the Great Lakes region with the front remaining dry.
422 AM MDT Fri Aug 30 2024 - Another taste of fall this morning with chilly temperatures near or sub freezing across western WY. East of the Divide will see highs range from the low to mid 80s with values west of the Divide reaching the mid to upper 70s. A potent area of high pressure builds into the western CONUS today. This high will keep warm and dry conditions over the CWA through the weekend. This low would bring chances for precipitation to other parts of the CWA but confidence is currently low at this time. Some models are starting to indicate the possibility for some widespread precipitation as a result of this low.
621 AM CDT Fri Aug 30 2024 - Below normal temperatures for today and tomorrow - Rain ending during the day today and into the afternoon - Cooler temperatures will prevail through the forecast period A rather strong cold front is moving through the region this morning which has brought a wide area of light rain and embedded thunderstorm activity.

1016 AM EDT Fri Aug 30 2024 A stationary front to our south will lift northward as a warm front tonight.
The circulation in the northwestern Gulf of Mexico associated with an upper level trough continues to extend its shear axis as far north as Louisiana and Texas.
Better chance for widespread showers and storms Saturday as a cold front approaches.
Early morning surface observations capture the position of a cold front, positioned from roughly New Richmond to the southwest towards Albert Lea at this hour. The departure of the cold front will signal the end of the recent active weather pattern that brought multiple rounds of severe weather to the Upper Midwest and will open the door for a gorgeous weekend ahead. The combination of afternoon highs in the upper 70s and dew points in the low to mid 50s will make for a much more comfortable feel as compared to the recent trend of Summer heat and humidity. Forecast profiles also support a fairly dry column, such that pieces are lining up for a dry cold frontal passage.
Dense cloud cover behind the front will bring cooler temperatures today, with forecast highs in the 70s to low 80s area wide. Current NBM forecast calls for highs in the low to mid 80s, but if clouds stay on the dense side, temperatures could be more similar to today.
354 AM MDT Fri Aug 30 2024 Warm and dry weather is expected over the weekend as upper level ridging builds in across the region, with highs in the 80s to low 90s at times.
830 AM MDT Fri Aug 30 2024 Building ridge will bring widespread clear skies and warmer temps today, with highs in the mid 80s to around 90F. JKL Ridging builds over the area today for sunny skies and warmer temperatures through the weekend. With thermal trof to the west of the divide winds turn northeast on Saturday, and then east Saturday night. Despite this, grasses will be increasingly dry through this warm ridge pattern, so continue to be very cautious with anything that can start a fire.
431 AM CDT Fri Aug 30 2024 A wetter and cooler pattern has arrived across the Midsouth.
636 AM EDT Fri Aug 30 2024 A warm front will lift north across the area this morning, followed by a cold front tonight into Saturday morning.
640 AM EDT Fri Aug 30 2024 (Today and tonight) Upper level ridging remains in control of the weather for this afternoon.

Cooler condns are on deck this aftn, w/ widespread cloud cover expected over much of the FA. Of note, temps wl be slightly cooler, e. Sat, a similar pattern is expected, w/ slightly cooler temps than Fri, and generally area-wide PoPs, though the primary axis of higher confidence PoPs wl remain acrs the N/Wrn portion of the state along the stalled frnt.
(Tonight through Saturday night) A weak upper ridge cover the southern part of the country this afternoon, but there is a weakness over TX. A cold front has moved into west TX and stretches from near Lawton, OK to Fort Stockton to El Paso. The cold front will move into our northern counties Saturday bringing isolated to scattered convection to most of the area.
Widespread showers and thunderstorms are in the forecast daily through the long weekend due to a series of slow moving cold fronts.
902 AM MDT Fri Aug 30 2024 Warm and dry weather is expected over the weekend as upper level ridging builds in across the region, with highs in the 80s to low 90s at times.
As we move into the weekend, a strong ridge of high pressure continues to build over the western U. High temperatures will rise into the 80s to lower 90s with even the lower valleys of north central Idaho breaking into the 100s. The stable conditions produced by the high pressure, as well as the lack of upper level winds, will result in potentially hazy and smokey conditions given the prevalence of wildfires in the region.
19Z water vapor imagery showed an upper low over the Hudson Bay with troughing extending into the upper Midwest. This trough axis was moving east through the middle MO river valley. Surface obs had high pressure across the central high plains with a cold front over the Ozarks.
241 PM EDT Fri Aug 30 2024 * Mostly cloudy and humid today/tonight with a spotty shower * Severe thunderstorms capable of producing damaging wind gusts and flash flooding are possible Saturday afternoon into the evening * Extended stretch of seasonably cooler, fall-like weather for the start of September Clouds breaks over the far NW mtns could allow for enough instability to generate a late day/evening shower or tstm. Severe weather is probable on Saturday afternoon and evening along/ahead of the weakening cold front.
347 PM EDT Fri Aug 30 2024 Multiple rounds of showers and thunderstorms will be possible until the passage of a cold front.
203 PM CDT Fri Aug 30 2024 - Cooler temperatures will continue through the weekend and the start of next work week (70s and 80s).
pdf High pressure over the region will keep dry air (PWATs =< 1.
335 PM CDT Fri Aug 30 2024 - A cold front Saturday brings additional breezy winds and a chance for showers and an isolated severe thunderstorm.
- Cooler temperatures expected this weekend and beyond. Chances for scattered showers and storms remain in the far southeastern portions of our region as instability associated with a cold front continues to progress east. Tonight's lows are expected to be at or slightly below-normal as a cooler, continental air mass behind the upper-level low settles into the forecast area and shifts the surface wind flow in a northerly manner. Temperatures appear to bottom out in a northeast- to-southwest gradient, with northern portions of the area in the upper 50s and places to the south experiencing lows in the lower to mid 60s tonight. Quieter weather is forecast for the weekend as 925MB surface analysis reveals a high pressure moving into south-central Iowa overnight. Highs are expected to range from the upper 70s to the lower 80s across the forecast area Saturday.
243 PM EDT Fri Aug 30 2024 Upper-level ridging remains over the southeastern U. This low is actually pulling some drier air over part of the state, leading some some relatively lower PW values. At the surface, the high pressure axis remains to our north and easterly low-level flow continues. We're already seeing a few showers and storms over the eastern part of the state and, similar to the past several days, we should expect the highest storm coverage across the west coast over the next several hours.
1143 AM MDT Fri Aug 30 2024 Warm and dry weather is expected over the weekend as upper level ridging builds in across the region, with highs in the 80s to low 90s at times.
The showers and storms will become more widespread as we move through the day as a cold front advances into northeast Oklahoma. (Saturday through Friday) The potential for scattered to numerous showers/storms continues on Saturday as the aforementioned cold front slowly sags south.
Another warm day with heat indices around 100 F to go through before we get to some cooler weather. Even with the lower dewpoints, this gives afternoon heat index values of around 100 degrees, which will be less than pleasant when you consider winds will be near calm.
1231 PM CDT Fri Aug 30 2024 A wetter and cooler pattern has arrived across the Midsouth.
Should this system remain offshore through the weekend, there is a chance that it could slowly develop into a tropical cyclone. Under mostly cloudy skies, temperatures are forecast to fall into the lower 70s.
(Now through Saturday) The pattern we have seen over the past couple of days continues through Saturday as our local area lies in between low pressure near Texas/Louisiana and ridging to our northeast. Meanwhile, subsidence from the nearby ridge will be in place across our northeastern zones.
Strong moisture transport east of the low combined with daytime heating has resulted in a favorable environment for deep convection.
- Below normal temperatures for today and tomorrow - Rain ending during the day today and into the afternoon - Cooler temperatures will prevail through the forecast period A rather strong cold front is moving through the region this morning which has brought a wide area of light rain and embedded thunderstorm activity. Temperatures behind this front are a decent amount cooler.
1121 AM MDT Fri Aug 30 2024 - Another taste of fall this morning with chilly temperatures near or sub freezing across western WY. East of the Divide will see highs range from the low to mid 80s with values west of the Divide reaching the mid to upper 70s. A potent area of high pressure builds into the western CONUS today. This high will keep warm and dry conditions over the CWA through the weekend. This low would bring chances for precipitation to other parts of the CWA but confidence is currently low at this time. Some models are starting to indicate the possibility for some widespread precipitation as a result of this low.
Storms with damaging wind gusts, large hail, and heavy rainfall are possible from 3pm-9pm this evening ahead of a cold front mainly east of the Illinois River. - A cold frontal passage overnight tonight into the day tomorrow will bring cooler, drier air to central and southeastern IL. Allowing the highs to drop into the upper 70s to low 80s for the holiday weekend and into the new week. Today a cold front will begin to move through the CWA from the NW to the SE. Behind it, cooler and drier air will seep into our forecast area. After the cold front makes its slow exit, we will see peak into fall.
(This evening through Saturday Night) A disorganized, weak surface trof/low situated offshore will remain the focus for some shower & thunderstorm chances across region over the weekend.
243 PM EDT Fri Aug 30 2024 (This afternoon through Saturday) Lee trough still situated across portions of northern GA this afternoon. The lee trough is expected to remain in place through tomorrow as a weak frontal boundary approaches from the west.
