Tomorrow should be another really nice day as high pressure sits over the area. Temps are expected to peak in the low 80s.
324 PM EDT Fri Sep 26 2025 High pressure will build across the region and will remain in control through the weekend.
1236 PM CDT Fri Sep 26 2025 - Clear skies and slightly cooler, drier air will continue through the weekend.
Updated at 1258 PM CDT FRI SEP 26 2025 - Cooler through the weekend.
- Clear skies and slightly cooler, drier air will continue through the weekend.
Upper air models show ridge just to the east of the FA this afternoon, and a bit flattened out as upper wave treks across Saskatchewan. Temperatures on Saturday will be slightly cooler, though still above normal with highs in the mid 70s to low 80s. Upper ridge builds back over the northern plains over the weekend though, resulting in warming temperatures and continuing dry conditions.
Updated at 1125 AM CDT Fri Sep 26 2025 - Drier and cooler air will filter in resulting in pleasant conditions this weekend.
There is an upper low centered over the western portion of the CWA which is evident on water vapor imagery. The upper low will make some eastern progress with Middle Tennessee on the backside of the low Saturday afternoon.
Looking more longer term, we continue to expect upper ridging to dominate the weather over the region through next Friday.
244 PM EDT Fri Sep 26 2025 High pressure builds into the region for the first part of the weekend.
An upper level trough over the eastern Conus swings east before settling over the East Coast anchored by a developing tropical system beginning to move north along the Florida Atlantic coast. The forecast area sees increasing northerly flow into the coming week as a weak cold front near the coast moves south over the Gulf.
Embedded on the trough axis is a cold front. At the surface the cold front is located from southwest North Dakota, to north central North Dakota, and moving southeast. Lows tonight in the post frontal cooling, will be cooler in the 40s. Saturday will be breezy again as the pressure gradient tightens between a high pressure moving through South Dakota overnight, and a low sitting in Wyoming. Through the weekend the Northern Plains will be in a broad ridging pattern with an upper high over the Central Plains.
A large area of high pressure has spread across much of the Mississippi Valley region today, with very light winds and dry air aloft. Temperatures are on track to top out near or slightly above 80 degrees today, which is a few degrees warmer than yesterday thanks mostly to another day of insolation. While today's mixing and slightly warmer temperatures may make this slightly more difficult in a few areas, particularly north of I-70, overnight lows are likely to be similar, and much of the residual moisture may just end up settling back near the surface considering that winds remain very weak and moisture advection minimal.
- Highs generally in the low to mid 80s this weekend.
1121 AM MDT Fri Sep 26 2025 - Slightly cooler (upper 70s) with breezy northwest winds behind a dry cold front today.
148 PM EDT Fri Sep 26 2025 High pressure will build across the region and will remain in control through the weekend.
1220 PM CDT Fri Sep 26 2025 The southern portion of a large posivively-tiled upper trough extending from southeast Canada to eastern Texas will swing eastward with a centralized weak cutoff low pressure area forming today over the southeast CONUS. The axis of the system will reach Georgia and the northeast Gulf by Saturday evening, and then stall between an upper ridge building over the Great Plains and an upper high pressure area over the Atlantic.
135 PM MDT Fri Sep 26 2025 KEY MESSAGES: - Gusty NW winds continue today behind a cold front with a Lake Wind Advisory in effect for Fort Peck Lake.
Upper level ridging will be in control through the short term with continued dry conditions. The afternoon highs will climb into the upper 80s to near 90 degrees across the Hill Country to the low to mid 90s elsewhere.
Surface and upper-level ridging will maintain control and keep things very quiet through tonight. With abundant sunshine, temperatures will reach the low-mid 80s by peak heating time today. Overnight lows will be similar to last night, perhaps a degree or two warmer in spots, generally mid-upper 50s, lower-50s in far northwest AR.
Rain showers along the cold front in the northwest have developed. Associated warm frontal boundary will pass through the forecast area this morning, along with a trailing cold frontal boundary not far behind. For Saturday, high pressure is progged to scoot across South Dakota. Highs Saturday will be a bit cooler, albeit still slightly above average, and mostly in the 70s.
(This evening through Saturday) High pressure at the surface will keep winds light and skies mostly clear for the rest of the day. Upper level ridging will begin to build over the are tomorrow as an upper low sits over the southwest and an upper trough moves over the eastern United States.
Upper ridging will prevail to begin the weekend, contributing to a gradual warming trend with the return of southeasterly surface winds.
113 PM PDT Fri Sep 26 2025 Weather conditions across the area are much quieter than yesterday in the wake of the recent cold front. Temperatures are running a good 15 degrees cooler than 24 hours ago and are expected to top out in the upper 60s to mid 70s in most areas.
Issued 210 PM CDT Fri Sep 26 2025 Tonight through Saturday night: Stratus deck behind the backdoor cold front halted and will continue across east central WI for the remainder of the afternoon. Cooler temps and calm winds are expected into the overnight hours. Fog would linger into Saturday morning before lifting after daybreak as warmer, southerly winds gradually pick up into the afternoon. Looking at summer-like temps for Saturday with high creeping into the low to mid 80s for Saturday afternoon. As it pushes further east the associated cold front is progged to drift southward across southern WI Saturday evening/night. However, given the dry conditions not expect any precip associated with this frontal passage and mainly will see a westerly wind shift along with a cooler airmass as high pressure begins to build in overnight.
(Today and tonight) High pressure centered over Missouri will continue to keep our weather quite pleasant for the rest of the afternoon and tonight. There is a surface lee trough over eastern Colorado / New Mexico which is keeping the winds up slightly higher across the western half of the area.
* Noticeably cooler, more seasonable temperatures expected as the calender flips to October. Recent ECONUS satellite imagery outlines an overall decreasing cumulus field from this morning with further clearing of the low-level cloud field progged by recent HREF guidance throughout the evening as high pressure begins to build into the region. Despite high pressure influence on the region, an upper- level low stationed south of the area will allow for high-level clouds to continue to stream into the region last this evening and into the overnight hours. Low temperatures overnight are progged by the bulk of model guidance to range from the mid-to- upper 40s across northwestern Pennsylvania to the lower 60s across southern portions of the Lower Susquehanna Valley, generally 5-10F above climatological averages.
217 PM MDT Fri Sep 26 2025 - An upper-level ridge keeps the region drier today through the weekend with temperatures warming back into the 70s and 80s. An upper level ridge will keep things dry as the upper level low passes the Intermountain West to the north. However, wind gusts up to 30 mph can't be ruled out for the Panhandle as the upper level low continues to push east tightening the pressure gradient against our ridging pattern.
Breezy west winds and about 10 degrees cooler today behind the dry cold front that passed through overnight.
The cold front has progressed through the county warning area into South Dakota. UPDATE A cold front continues to progress across the south central North Dakota in to the James River Valley. Embedded on the trough axis is a cold front. At the surface the cold front is located from southwest North Dakota, to north central North Dakota, and moving southeast. Lows tonight in the post frontal cooling, will be cooler in the 40s. Saturday will be breezy again as the pressure gradient tightens between a high pressure moving through South Dakota overnight, and a low sitting in Wyoming. Through the weekend the Northern Plains will be in a broad ridging pattern with an upper high over the Central Plains.
727 PM EDT Fri Sep 26 2025 High pressure will build across the region and will remain in control through the weekend.

539 PM MDT Fri Sep 26 2025 - An upper-level ridge keeps the region drier today through the weekend with temperatures warming back into the 70s and 80s. An upper level ridge will keep things dry as the upper level low passes the Intermountain West to the north. However, wind gusts up to 30 mph can't be ruled out for the Panhandle as the upper level low continues to push east tightening the pressure gradient against our ridging pattern.
Clear skies and light winds are expected tonight as a weaker upper-level ridge develops behind last night's exiting trough.
Mainly dry weather persist today as high pressure traverses north of the region, with just a few isolated (20%) showers possible across southwest VA northeast across the mountains. Highs will range from the mid 70s to 80 across the lowlands, with mid 60s to low 70s in the mountains. Highs on Saturday will be in the low 70s to low 80s across the lowlands, with 60s in the mountains. Mainly dry conditions will return to the area for the end of the weekend and start of the new work week as the aforementioned upper disturbance shifts northeast and mid level ridging attempts to build across the region.
721 PM EDT Fri Sep 26 2025 High pressure builds into the region for the first part of the weekend.
507 PM EDT Fri Sep 26 2025 High pressure builds into the region for the first part of the weekend.
- Temperatures will remain seasonably pleasant, near early autumn normals, with no unseasonable heat or strong cold fronts expected. An upper level ridge will build above the area over the next several days bringing dry conditions to western Kansas. Winds will generally be from a southerly direction through tonight before a weak cold front moves through the area Saturday morning shifting winds briefly to the north. Winds will trend light NEly behind a weak dry cold front daylight Saturday.
/issued 113 PM PDT Fri Sep 26 2025/ Weather conditions across the area are much quieter than yesterday in the wake of the recent cold front. Temperatures are running a good 15 degrees cooler than 24 hours ago and are expected to top out in the upper 60s to mid 70s in most areas.
619 PM CDT Fri Sep 26 2025 An upper level trough over the eastern Conus swings east before settling over the East Coast anchored by a developing tropical system beginning to move north along the Florida Atlantic coast. The forecast area sees increasing northerly flow into the coming week as a weak cold front near the coast moves south over the Gulf.
722 PM CDT Fri Sep 26 2025 Updated at 541 PM CDT FRI SEP 26 2025 - Cooler through the weekend.
717 PM CDT Fri Sep 26 2025 - Clear skies and slightly cooler, drier air will continue through the weekend.
Analysis and current conditions: Upper level analysis and water vapor imagery show a trough shifting into the southeast U. , upper ridging over the southern into central plains and a nearly stationary low over southern CA. At the surface, high pressure was centered over the region behind the cold front which has shifted well south into the Gulf. Could see some cumulus develop during the afternoon, but otherwise should be sunny again with highs in the low to mid 80s.
Discussion An upper low will shift eastward across the southern TN valley over the next 24 hours or so. The proximity of this upper low will lead to increased lapse rates aloft and should result in continued isolated to scattered showers through the remainder of the night and into the daytime hours today.
- Light snow can't be ruled out for the highest elevations over the weekend though no impacts are expected to roadways. H500 hand analysis and satellite imagery is showing the closed low has migrated to the Baja region as anticipated while the northern stream wave is moving through the Northern Plains. Satellite derived PWAT suggests the SW cyclone is tapping into the SubTropics and possibly even pulling in moisture associated with Narda out in the EPac. Model dynamic trop and mid level moisture fields show this feature lifting across the 4 Corners by mid afternoon on the nose of a jet emerging on the downstream side of the low. The SoCal low will begin to lift northward on Sunday as a larger trough moves into the EPac.
High pressure will dominate the forecast the next several days, providing dry conditions and a warming trend.
Over the far west and Keweenaw southerly winds helped keep the low levels mixed with temperatures only falling to around 50 and then warming some overnight as winds increased and high clouds moved in. The first system will move through Manitoba into northern Ontario today dragging a cold front through the U. Upper level ridging will build into the Midwest Sunday through midweek resulting in rather quiet weather with plenty of sunshine and afternoon highs 5 to 15 degrees above seasonal averages (upper 60s to mid 70s).
Southerly surface winds will help maintain high temperatures that, while cooler than previous days, are still seasonably warm and mostly in the 70s with a few 80 degree readings possible. Continued southerly flow at the surface and an amplifying ridge will lead to well above average temperatures in the 80s.
Updated at 1148 PM CDT Fri Sep 26 2025 - Drier and cooler air will filter in resulting in pleasant conditions through this weekend.
This fog will dissipate by mid-morning, with high pressure to the north and west helping to promote a mostly sunny sky in this drier air mass. With ample sunshine, highs should climb into the low to mid 80s in most locations by the afternoon.
(Tonight through Sunday Night) Some patchy fog is possible after midnight tonight, with the highest likelihood on the Cumberland Plateau. As the upper low keeps spinning over Middle Tennessee into the weekend, expect some slight chances of thunderstorms to linger in the east. Sunday, the upper low will be far enough to our east that rain will not be a concern and temperatures will once again top out in the mid 80s.
Daytime heating will generate additional showers and isolated thunderstorms over west central and southwest Florida this afternoon, with the highest pops across the nature coast and I-4 corridor in region of best available deep layer moisture along and just south of the frontal boundary.
Water vapor imagery this afternoon displays a mid- to upper-level ridge centered over the south-central CONUS. At the surface, high pressure overspreads much of the east-central CONUS, bringing clear skies to the area and afternoon highs expected in the low to mid 80s, about 5 to 10 degrees above the climatological average for late September. The continued ridging will help to keep dry conditions through much of the week.
Upper level trof will continue to move east this weekend and behind it upper level ridging builds in from the Plains. Starting the week off with ridging aloft and continued troughing to the east. High pressure continues at the sfc and temps remain above normal for the early week.
An upper level trough will continue to swing over the Southeast, pushing northeast of the Tennessee Valley late Saturday afternoon into Saturday night. At the surface, the cold front has largely passed to our southeast tonight; however, the parent low pressure system's trajectory takes more of a northeasterly turn on Saturday.
(Tonight through Sunday night) We are waking up this Saturday to many locations dropping into the 60s across the region, especially away from the warmer water bodies. The overall synoptic pattern has as broad scale trough over the eastern US with an mid and upper low over northern Alabama. Thankfully, the lower dewpoints will help make the very warm conditions a bit more tolerable.
High pressure over the forecast area will start to shift eastward today as a wet, cooler pattern begins to materialize for the PacNW late Sunday onward.
313 AM CDT Sat Sep 27 2025 - Breezy northerly winds this morning behind a cold frontal passage with highs today in the mid 70s to mid 80s. A slightly cooler day is expected across the area in the wake of the cold frontal passage. Clear skies and light winds tonight will result temperatures sinking into the low 50s, with upper 40s possible across far northwestern portions of the area. Ridging builds over the Midwest on Sunday with troughing over the southwestern U. As of late, temperatures have been on the higher side of model guidance on days similar to Sunday, so wouldn't be surprised to see southern portions of the area to see highs near 90 degrees.
/Issued 637 PM MDT Fri Sep 26 2025/ Given upper level ridging in place, no major changes were needed with the forecast tonight. -AM /Issued 300 PM MDT Fri Sep 26 2025/ - Meteorological Overview: Behind the cold front passage earlier today, upper level ridging continues to build in over the next few days. This ridging pattern will keep above normal temperatures through the weekend. On Sunday, southwest flow aloft moves in with a trough building along the Pacific Coast.
(Today and tonight) Upper ridging will strengthen slightly today, with temperatures warming a couple degrees. High will be in the lower 90s in the Concho Valley and Big Country with upper 80s elsewhere.
(Tonight through Sunday night) A trough, currently spinning over the Southwestern US, is expected to stay nearly stationary over the region through Saturday before beginning to lift on Sunday. Mid to high- based clouds will move into the Panhandles throughout the day causing temperatures to be cooler than Saturday, especially in the western Panhandles.
Updated at 125 AM CDT SAT SEP 27 2025 - Cooler today.
UPDATE The cold front has progressed through the county warning area into South Dakota. UPDATE A cold front continues to progress across the south central North Dakota in to the James River Valley. Embedded on the trough axis is a cold front. At the surface the cold front is located from southwest North Dakota, to north central North Dakota, and moving southeast. Lows tonight in the post frontal cooling, will be cooler in the 40s. Saturday will be breezy again as the pressure gradient tightens between a high pressure moving through South Dakota overnight, and a low sitting in Wyoming. Through the weekend the Northern Plains will be in a broad ridging pattern with an upper high over the Central Plains.
Our area remains under upper level ridging throughout the short term. This means seasonable highs in the low 90s to upper 80s and low temperatures in the 60s.
202 AM EDT Sat Sep 27 2025 High pressure will build in from the west today cresting over the area late in the day. High pressure will move east of the region tonight. A weak cold front will cross the area Sunday.
The best dynamics have shifted south to this location as well as the lower deserts of central and southern Arizona and a Severe Thunderstorm Watch has been issued until 7pm for this area. The cause of today's active pattern continues to be the cutoff Low pressure system over California which is now entering the Lower Colorado River Valley and plans to park over Yuma the next couple days. The area will see one final round of showers and thunderstorms, but with cooler temperatures being mixed down to the surface over the last couple days, these storms aren't expected to be as strong as the previous days.
-Patchy fog will be possible across the state during the morning hours -Dry conditions are expected over the next several days due to high pressure over the region -Temperatures are expected to be average to slightly above average A mostly settled weahter pattern is expected across the region over the next several days.
- Temperatures will remain seasonably pleasant, near early autumn normals, with no unseasonable heat or strong cold fronts expected. An upper level ridge will build above the area over the next several days bringing dry conditions to western Kansas. Winds will generally be from a southerly direction through tonight before a weak cold front moves through the area Saturday morning shifting winds briefly to the north. Light south winds will shift to the northeast and east at 10 kts by 15-17z as a weak cold front approaches and stalls out.
- Light snow can't be ruled out for the highest elevations over the weekend though no impacts are expected to roadways. This increase in moisture is all thanks to the closed low spinning over southern California that will remain stationary through early Sunday morning. Flow around the low will allow moisture to keep streaming into the area.
1233 AM CDT Sat Sep 27 2025 Ridging aloft from a building high pressure over northeastern Mexico is expected to keep dry conditions (less than 10% PoP's) across most of Deep South Texas and the Rio Grande Valley today through the daytime tomorrow, outside of a low (15-20%) chance of rain for southern portions of Cameron County tomorrow afternoon.
High pressure will remain at the surface through the period, with an upper level trough moving out by Sunday morning. A large omega blocking pattern develops, with a 590dam ridge extending from TX into the Great Lakes.
The trough is being pushed across the Northern Rockies by an upper-level jet that is centered over southwestern Canada and Montana with Wyoming at it's nose. As the trough shifts east through the morning, enhanced vertical mixing aloft, moisture, and an associated weak front, will shift the shower chances east across the northern Green River Basin and into the Wind River Basin through midday today. By tonight, high pressure returns for Saturday with another day of above normal temperatures and dry weather. Guidance remains in consensus that the California low and it's moisture will be absorbed into a trough and push into the Intermountain West on Sunday.
A closed upper level low is over the TN Valley early this morning, with deep moisture streaming northward along and east of the Appalachians. Brief saturation in the lower levels is producing some brief cloudiness across south-central KY early this morning. The upper low is forecast to rotate eastward through tomorrow while weakening. Meanwhile, amplifying ridging is forecast to build east across the Plains and Midwest. Rising heights aloft and increasing low-level thicknesses will support slightly warmer temps each day.
321 AM EDT Sat Sep 27 2025 High pressure will build across the region and will remain in control this weekend.
145 AM EDT Sat Sep 27 2025 High pressure will build across the region and will remain in control through the weekend.
Progressing into the workweek, large scale ridging will keep temperatures above average.
