After midnight, a weak cold front will sag southward into the area, accompanied by a northerly wind shift, and a period of gusty winds toward daybreak Friday that could see winds gusting to around 20-25 mph. The best chance for precipitation (20-30%) will exist along and west of the Pecos River, where upslope flow against the higher terrain will facilitate additional development. Precipitation will once again taper off after sunset Friday evening, paving the way for a quiescent night with lows again in the 50s and 60s for most, and even some upper 40s possible in the higher terrain of the Davis Mountains.
(Tonight) An area of low pressure, located south of the TX/LA coast should remain offshore into Friday. An expanse of moisture partially associated with the low continued to spread across much of the Deep South.

1123 PM EDT Thu Sep 5 2024 - After another warm day on Friday, a cold front passing on Friday night will bring a noticeable cool-down for the weekend. - Showers or thunderstorms are possible late Friday into Friday night in association with a cold front. An upper level trough is dropping southeast over the north central CONUS late today, with an associated surface cold front extending from MI southwest through the Mid Mississippi Valley.
242 AM CDT Fri Sep 6 2024 - A cold front continues to pass through the forecast area. A cold front is currently passing through central Illinois. For the weekend, highs will be quite cooler than we have been seeing lately.
123 AM EDT Fri Sep 6 2024 High pressure will slowly exit to the east overnight.
204 AM CDT Fri Sep 6 2024 - A cold front will bring markedly cooler temperatures this weekend and refreshingly lower humidity. An upper trough is nudging a front toward the area backed by air from north central Canada. The front brings much cooler and drier air into the region.
217 AM MDT Fri Sep 6 2024 A ridge of high pressure will remain in control of our weather pattern today and into the weekend.
(Today and tonight) A weakening cold front is currently moving southward across the area. Despite breezy northeasterly winds, high temperatures will be similar to that of today, generally in the low-to-mid 80s.

157 AM EDT Fri Sep 6 2024 A fast moving cold front will increase the risk for showers and storms later this afternoon and into the overnight hours.
Temperatures along the Keys island chain are hovering in the lower to mid 80s, with oppressive dewpoints in the upper 70s, and winds on land from the east to southeast around 10 mph. Surface analysis depicts Atlantic high pressure extending westward into the Florida peninsula, with a stationary front lying from offshore of the Carolinas across North Florida and along the northern Gulf Coast. Aloft, the subtropical ridge is dominant at all levels across our region. Hot and generally drier than normal weather is expected to continue across the Keys today and through the weekend, as ridging aloft remains dominant over our area. Mid latitude troughing over the eastern CONUS will maintain the stationary front draped over north Florida, but the subtropical ridge will not allow this front to progress farther southward.
Winds are generally calm tonight as high pressure settles into the area. Look for overnight lows in the middle 40s for most areas, with isolated cooler spots in northwest Minnesota.
A strong ridge of high pressure will remain centered over the Northern Rockies for the next couple days.
1218 AM CDT Fri Sep 6 2024 - Dry high pressure will remain in control of the area through Friday, with temperatures staying slightly below normal for this time of year.
1227 AM CDT Fri Sep 6 2024 (Tonight) An area of low pressure, located south of the TX/LA coast should remain offshore into Friday. An expanse of moisture partially associated with the low continued to spread across much of the Deep South.
Water vapor satellite imagery this morning shows a rather potent mid/upper trough digging into the Upper Midwest/Great Lakes region with a subtle ripple embedded within weak northwest flow across the central plains. With skies clearing, afternoon temperatures are still forecast to rise into the low to mid 80s, but dewpoints in the 50s will make conditions feel a bit more pleasant today.
1216 AM CDT Fri Sep 6 2024 - A cold front will bring markedly cooler temperatures this weekend and refreshingly lower humidity. A cold front makes its approach and passage during the next 24 hours.
1148 PM CDT Thu Sep 5 2024 - A cold front will bing a 20-30% chance of showers to central IL late tonight and early Friday morning. A cold front has reached the Illinois River, with southwest winds shifting to northwest behind the front. 37 A cold front was analyzed over eastern IA at 18z and regional radars showed a broken band of post frontal showers behind it. The main story will be the arrival of a much cooler airmass on north/northwest winds gusting 15-25 mph. Much of central IL will only see low/mid 70s highs Friday, with areas south of I-70 still getting into the lower 80s.
1201 AM CDT Fri Sep 6 2024 - Scattered showers and storms (15-30% chance) this afternoon and evening as a cold front continues to move through the area. - Cooler temperatures build in behind the front with below normal temperatures Friday through the weekend.
An area of low pressure along the northern Gulf Coast will help support mostly cloudy to overcast conditions throughout the day, with very low (10-20%) chances for light pockets of rain during the afternoon (mainly south of the Tennessee River). Model soundings show plenty of dry air in the low-levels of the atmosphere, however, and most of this precipitation will end up being virga.
Temperatures are warmer along the coast (low to mid 80s), whereas inland locations are several degrees cooler (mid/upper 70s).
(Today and tonight) As of 1:30 AM, a cold front was draped from around Hobbs, New Mexico to Childress, TX extending northeast into Oklahoma. An upper level disturbance rounding the eastern periphery of the upper ridge across the Western CONUS will create chances for isolated showers and storms across much of West Central Texas as there is still some decent low to mid level moisture across the area to work with (indicated by forecast pWats in the 1-1. High temperatures will be near to slightly above where they were yesterday with most places climbing into the mid to upper 80s with a few locations in the northeastern Big Country seeing some readings in the low 90s. With drier air beginning to work its way into the area overnight, lows tonight will be a bit cooler falling into the low to mid 60s.
Our near term weather will be influenced by dry northwest flow aloft between Rockies ridging and a southeast Canada closed upper low. The cooler air aloft will result in steep low level lapse rates this afternoon however, which could produce isolated light showers from northeast IA into the Upper MS Valley closer to the Great Lakes upper low.
Synoptic overview and current conditions: Upper level analysis and water vapor imagery show a large upper trough extending from western Ontario into the mid Mississippi valley region with an upper level ridge axis from the southwest U.
The high moisture will again allow for some heavy rains possibly causing urban flooding with the storms this afternoon and have a marginal risk of excessive rainfall in place across the area for this. Highs will warm into the upper 80s north to the lower 90s central and south, with some pockets of mid 90s possible. The high humidity will allow for Heat Indices generally around 105, though there may be some pockets of up to 110 in those warmer locations. Winds become more southerly for the weekend, and will shift the highest rain chances inland, though they will still be scattered to numerous across the area.
1154 PM EDT Thu Sep 5 2024 - Scattered showers and an isolated storm possible early this morning in association with southeastward sinking cold front.
1244 AM CDT Fri Sep 6 2024 High pressure has become re-established at the surface, but not for much longer. A cold front is poised to sweep across Middle Tennessee tomorrow night, accompanied by minimal PoPs but also a substantial temperature drop. (This afternoon through Friday Night) Our quiet weather will continue today as a short wave ridge moves overhead. Highs will be a bit warmer compared to yesterday pushing into the lower 90s for some.
1045 PM CDT Thu Sep 5 2024 Updated at 1040 PM CDT Thu Sep 5 2024 - Showers & some storms possible into early Friday - Low chance again Friday afternoon in SE - Near/below average temperatures continue into the weekend (This evening through Friday) Cold front is beginning to move into far NW Oklahoma.
330 AM EDT Fri Sep 6 2024 High pressure will slowly exit to the east this morning.
957 PM MDT Thu Sep 5 2024 - Warmer and mostly dry conditions through the weekend. Water Vapor and upper air models show upper ridge over the western CONUS, with upper trough digging into the Great Lakes region, and northwest flow over the forecast area. Aside from that, expect dry conditions through the weekend as the upper ridge begins to slide over the Rockies into the plains.
Temperatures are on the cooler side, between the mid-40s to mid-50s area wide. The upper- level ridge will build over the region today as warm air advection at 700mb bring warmer temperatures into the region.
321 AM EDT Fri Sep 6 2024 High pressure will weaken across the region today.
A isolated showers and possibly few thunderstorms will remain possible through this evening, associated cold frontal movement. A beautiful weekend will be on display behind today's cold front, with highs in the mid 70s to lower 80s and rain free conditions. High pressure will bring seasonable temperatures and dry weather next work-week. A few thunderstorms may also form this afternoon as daytime heating occurs, though thunder potential remains on the low end as the environment remains very stable. A deep upper-level low pressure system will begin pushing east over the Great Lakes region as we head closer to daybreak.
328 AM CDT Fri Sep 6 2024 - Cooler temperatures build in behind the front with below normal temperatures Friday through the weekend.
Main upper level low is still north of the area this morning. With the strong CVA and cooler air aloft, think that going at least schc is a good forecast.
139 AM EDT Fri Sep 6 2024 - After another warm day today, a cold front passing tonight will bring a noticeable cool-down for the weekend. - Showers or thunderstorms are possible late this afternoon into this evening in association with the passing cold front. An upper level trough is dropping southeast over the north central CONUS late today, with an associated surface cold front extending from MI southwest through the Mid Mississippi Valley.
142 AM EDT Fri Sep 6 2024 High pressure maintains a cool northeast breeze through today, keeping temperatures below normal.
525 AM EDT Fri Sep 6 2024 High pressure remains in control for one more day keeping conditions mild and dry. Rain and cooler temperatures return to the region tomorrow as a frontal system moves through.
525 AM MDT Fri Sep 6 2024 - High pressure builds in today through the weekend with dry and warm conditions, although isolated storms are still possible over the mountains each afternoon.
533 AM CDT Fri Sep 6 2024 (Today through Saturday afternoon) WV imagery this morning shows the upper ridge centered over the junction of Arizona/Nevada/Utah, buttressed by a Canadian trough extending through Ontario in Minnesota. Just to the north, a cold front has entered northern Lea County, and is set to intrude upon the rest of the CWA today. Best chances today look to be in the lee of the mountains as the cold front generates upslope flow. Overnight lows should be a degree or two cooler than this morning's. Saturday, temperatures will be a couple of degrees cooler than today, mainly south as post-frontal air continues working south, making Saturday perhaps the coolest day this forecast.
Cold front moves through tonight into Saturday morning with mostly dry conditions. An associated surface cold front will move across the region. Low rain chances Saturday morning for portions of northeast TN, east TN mountains, and southwest VA as a cold front moves through. Cooler than normal temperatures this weekend, followed by near normal temperatures during the new work week. A cold front will bring a few showers to the northeastern third of the forecast area Saturday morning, and usher in below normal temps for the weekend.
Temperatures are already in the low to mid 80's with around 90 percent humidity.
- Cooler than normal temperatures through this weekend, with widespread lows in the 40s Saturday morning. Otherwise, the models suggest that low-level cold advection will continue through the morning, leading to a cooler day with highs in the low to mid 70s. This Weekend: Mid-level troughing initially centered over the Great Lakes is forecast to shift east with building upstream heights over the Canadian Prairie provinces and north-central states.
AM MDT Fri Sep 6 2024 Aviation Section Updated High pressure will continue to keep much of the region hot and dry over the next couple days.
Current surface analysis places high pressure from the lee of the Rockies through the Central and Northern Plains. Upper level analysis places low over Hudson Bay through Ontario, with broad high over the desert southwest and ridge to the north. For today, dry conditions but a bit below average temperatures remain over our area given the cool high pressure settled in. Going through the weekend, upper ridge to the west gradually creeps towards the east keeping dry weather over the area, but allowing a gradual warming trend to develop.
340 AM MDT Fri Sep 6 2024 - High pressure builds in today through the weekend with dry and warm conditions, although isolated storms are still possible over the mountains each afternoon.
Temperatures are on the cooler side, between the mid-40s to mid-50s area wide. The upper- level ridge will build over the region today as warm air advection at 700mb bring warmer temperatures into the region. Saturday will be very similar to Friday as the upper-level ridge remains fixed in place. Continued warm air advection at 700mb will usher in warm 700mb temperatures, leading to warmer surface temperatures throughout the day. Along with the subtle warm air advection at 700mb, some vorticity maxima will traverse through the 500mb ridge.
So despite the moisture over-running the front along the coast, it is still having trouble making to the surface with the high pressure in place. The model consensus supports the higher rain chances across the south, so have pretty high confidence of the southern half being wet through tonight. This will help to pinch out the high pressure over the area and allow moisture to begin to return to the front itself as we progress through the day on Saturday.
With the lower convective activity, at least to start, comes less cloud cover and a quicker warm up across the area.
An upper level trough digging into the Great Lakes region is the culprit of our short stint of Fall- like weather. Lows tonight dip into the low to mid 40s across central and southern Minnesota with upper 30s likely across portions of western Wisconsin. Twin Cities metro will be kept warmer due to the urban heat island effect. All the talk of frost and near freezing temperatures has everyone thinking about what comes next [Winter]? Let's pump the brakes as a big Summer-like warm up arrives for the remainder of the forecast period.
Upper ridge will slide east late Saturday and allow a more southerly flow aloft to ramp up overnight.
Synoptic overview and current conditions: Upper level analysis and water vapor imagery show a large upper trough extending from western Ontario into the mid Mississippi valley region with an upper level ridge axis from the southwest U. The upper level low will drop southeast into the Great Lakes region and a cooler drier air mass will begin to descend southward into the area. Lows tonight are expected in the low to mid 50s with smoe valleys in the eastern Ozarks dipping into the upper 40s. Abundant sunshine is expected on Saturday with the area of high pressure moving over the area. Cooler through the weekend: The cooler air mass will remain over the area through the remainder of the weekend with lows Saturday night in the 40s most locations.
(Today through Saturday) A broad upper trough remains over the E half of the US. At the surface, the County Warning Area (CWA) remains sandwiched between a stationary front over the N GOMEX and a cold front from lower MI to N TX. A high pressure ridge and associated wedge continues from New England to N GA.
High pressure will bring dry and unseasonably warm conditions today.
621 AM CDT Fri Sep 6 2024 (Today through Saturday night) Looking forward to another pleasant September day today, with clouds and northeast winds keeping highs a few degrees cooler than yesterday. High pressure to the west will build towards the Plains, allowing for sunnier skies and temperatures reaching a few degrees warmer than today, but still in the 80s.
608 AM CDT Fri Sep 6 2024 (Today through Saturday) Latest Consensus of CAMs solutions showing more areal coverage potential for isolated showers and thunderstorms beginning across northwestern portions of our area this afternoon, spreading southeastward/eastward as surface cold front pushes into mid state region late this afternoon, and southeast of our area after midnight tonight.
Today we see the beginning of our dry pattern as the upper ridge pushes over the High Plains. Overnight lows will be in the low to mid 50s. A stronger system is possible towards the end of the work week with a chance for storms and cooler temperatures.
955 AM CDT Fri Sep 6 2024 - A cold front continues to pass through the forecast area. The surface cold front has pushed south of the forecast area, currently located over the Ohio Valley. The parent upper low is noted on water vapor imagery over the Great Lakes Region and will push southeast today as surface ridging approaches from the northwest. NMA A cold front is currently passing through central Illinois. For the weekend, highs will be quite cooler than we have been seeing lately. Lows in the low to mid 40s are on deck for the next 3 nights.
721 AM EDT Fri Sep 6 2024 A fast moving cold front will increase the risk for showers and storms later this afternoon and into the overnight hours. Much cooler on Saturday.
547 AM CDT Fri Sep 6 2024 - Temperatures will trend cooler for Friday through Saturday.
651 AM CDT Fri Sep 6 2024 A isolated showers and possibly few thunderstorms will remain possible through this evening, associated cold frontal movement. A beautiful weekend will be on display behind today's cold front, with highs in the mid 70s to lower 80s and rain free conditions. High pressure will bring seasonable temperatures and dry weather next work-week.
Water vapor satellite imagery this morning shows a rather potent mid/upper trough digging into the Upper Midwest/Great Lakes region with a subtle ripple embedded within weak northwest flow across the central plains. With skies clearing, afternoon temperatures are still forecast to rise into the low to mid 80s, but dewpoints in the 50s will make conditions feel a bit more pleasant today. A reinforcing backdoor front should allow for slightly cooler and drier air to dominate the forecast area on Saturday.
848 AM MDT Fri Sep 6 2024 Satellite imagery this morning shows little or no clouds across the region with upper level high pressure remaining centered across the interior western US. Some higher level smoke, primarily originating in OR, is moving over the ridge across the Northern Rockies and will likely contribute to increasing haze across the area today. Hoenisch High pressure will continue to keep much of the region hot and dry over the next couple days.
620 AM CDT Fri Sep 6 2024 (Friday through Saturday Night) Lower Miss Valley remains under the influence of an upper level trough, spinning across SE TX, into Central and NE LA this morning but this feature will slowly begin shifting eastward by late afternoon. As is does, a more progressive, westerlies upper trough will pivot south and east across the Southern Plains. Forcing tied to the trough across our southeast half and increased forcing tied to the upstream trough will provide scattered to numerous showers with isolated thunderstorms once again today across the entire Four State region with the greatest coverage expected to be across our southeast half.
Meanwhile, expansive high pressure across the North Atlantic extends westward towards the Florida Peninsula. The influence of the ridge is slowly decaying in the vicinity of the Florida Keys, supported by low-level falling geopotential heights sampled in the 12z morning sounding at KEY. With ample sunshine, temperatures peaking in the lower 90s, and dew points in the upper 70s to near 80, another Head Advisory day expected. From synopsis, expansive high pressure over the western North Atlantic extending westward into the Florida Peninsula will promote gentle to moderate east to southeast breezes through the next several days.
451 AM MDT Fri Sep 6 2024 Aviation Section Updated High pressure will continue to keep much of the region hot and dry over the next couple days.
612 AM CDT Fri Sep 6 2024 - Cooler temperatures build in behind the front with below normal temperatures Friday through the weekend.
636 AM EDT Fri Sep 6 2024 High pressure will weaken across the region today. Weak low pressure moving east along an old frontal boundary to our south could spread some light rain across parts of the area south and east of Interstate 85 late today and tonight, before a cold front sweeps southeast across the region on Saturday.
PoPs today 50-70%, with the highest chances along and north of the I-4 corridor. Highs today will reach the lower 90s, with muggy conditions producing heat indices between 102-106 degrees.
