1011 AM EDT Tue Oct 21 2025 High pressure shifts offshore today as a cold front approaches and moves across the forecast area tonight. Mid-morning update: Skies are sunny this morning, but clouds and a few showers are moving through the Ohio Valley in advance of an approaching cold front. An approaching cold front will push through the forecast area this evening and into the overnight. As the cold front pushes through, 00Z guidance shows a line of light rain showers moving through the area. The line of showers is forecast to move through this evening after sunset, with precipitation chances highest for those east of the Blue Ridge.
- Cooler air will arrive later today and persist through the end of the work week, with very low chances for frost development both tonight and Wednesday night. (Today) The core of a deepening northern stream trough will continue to dig southeastward across northern MN this morning, before advancing east-southeastward into the central Great Lakes later today. This fast-moving band of precipitation should exit the southeastern portion of the CWFA by 19-21Z, with a cold front following quickly in its wake.
752 AM EDT Tue Oct 21 2025 - Showers with gusty winds this morning - Showers with a chance of storms this afternoon into tomorrow - Cooler weather with chances for showers ahead - Showers with gusty winds this morning Latest radar shows bands of showers moving inland from the west. - Cooler weather with chances for showers ahead The strong upper level low will continue to dominate the pattern through most of the week.
641 AM EDT Tue Oct 21 2025 After brief high pressure today, cooler and more unsettled weather moves in for the rest of the week.
619 AM CDT Tue Oct 21 2025 Updated at 619 AM CDT Tue Oct 21 2025 - Dry cold front brings temperatures back down to near normal for Tuesday.
623 AM CDT Tue Oct 21 2025 Updated at 623 AM CDT Tue Oct 21 2025 - Cooler temperatures this week with some cold nights.
358 AM MDT Tue Oct 21 2025 - Dry weather and a gradual warming trend for the rest of the week Water vapor imagery shows the upper low now crossing MN, with northwest flow across the CWA. A wave is rounding the backside of the low across the eastern Dakotas, where gusts over 50 mph are occurring. Upper ridging will build across the region in general, but there is a wave crossing the northern Rockies. Dry weather today will continue through the next several days, as upper ridging dominates the northern Rockies region.
640 AM CDT Tue Oct 21 2025 - Cold front will move across the area today and bring a chance for rain.
1146 AM CDT Tue Oct 21 2025 Updated at 1137 AM CDT Tue Oct 21 2025 - Dry cold front brings temperatures back down to near normal for Tuesday.
213 PM EDT Tue Oct 21 2025 Dry high pressure will dominate through much of the week. Another dry cold front will move across the region tonight, mainly affecting winds and temperatures. Latest surface analysis shows high pressure offshore, while a cold front is starting to knock on Appalachia's door. Pre-frontal warming from some deeper southwesterly flow has allowed for temperatures to kick up into the low-to-mid 70s so far this afternoon, and some spots in the Pee Dee region are expected to go a couple more degrees throughout this afternoon. All eyes on the cold front this period, as it will gradually move from west to east over the next several hours, passing over the coastal Carolinas during the overnight hours tonight. Lows tonight only bottom out into the low-to- mid 50s inland, mid-to-upper 50s at the coast.
331 PM EDT Tue Oct 21 2025 A warm front approaches and moves across the area this evening, followed by a cold front late tonight into Wednesday morning.
- Showers will move out of the area this afternoon as a cold front brings drier air into the region.
Below freezing temperatures were experienced last night across most of the Treasure Valley and Magic Valley agricultural areas which brings the 2025 growing season to an end. Tonight's temperatures will not be quite as cold as they were early this morning, but temperatures will drop quickly again after sunset falling to near or below freezing in most areas.
323 PM CDT Tue Oct 21 2025 - A Frost Advisory is in effect for the whole area tonight into Wednesday morning for temperatures mostly in the low to mid 30s.
148 PM EDT Tue Oct 21 2025 After brief high pressure today, cooler and more unsettled weather moves in for the rest of the week.
Currently the upper low pressure system that brought us the rainy and windy weather, is now entering the Great Lakes Region. The low pressure system does still have some influence in North Dakota from about Jamestown east. The low stratus from this morning is still slowly trying to erode west to east, as high pressure is pushing into the west. Through this evening those clouds should continue to erode as high pressure moves more into the state. One is temperatures may be cooler than the NBM is forecasting, so we used the 25th percentile of the NBM for lows tonight. And two, patchy fog could form, mainly in the low valleys.
1127 AM MDT Tue Oct 21 2025 - Dry weather and a gradual warming trend for the rest of the week Water vapor imagery shows the upper low now crossing MN, with northwest flow across the CWA. A wave is rounding the backside of the low across the eastern Dakotas, where gusts over 50 mph are occurring. Upper ridging will build across the region in general, but there is a wave crossing the northern Rockies. Dry weather today will continue through the next several days, as upper ridging dominates the northern Rockies region.
1139 AM MDT Tue Oct 21 2025 - Some valleys are nearing or have fallen below freezing temperatures tonight.
205 PM EDT Tue Oct 21 2025 Upper level low pressure will slowly track across the Great Lakes over the next several days. A surface cold front will cross the area today offering some showers ahead of it.
Otherwise, any showers and storms should be to our east by this evening as this is when a cold front should have already moved through.
927 AM MDT Tue Oct 21 2025 - Some valleys are nearing or have fallen below freezing temperatures tonight.
1132 AM PDT Tue Oct 21 2025 * Quiet weather is expected across the region today, with a low pressure system bringing mountain precipitation chances, slightly cooler temperatures, and breezy winds to the region tomorrow.
- Colder temperatures move in later today with overnight lows dropping to the low to mid 40s. (Tonight) The line of showers has mostly dissipated as it has moved east of the area and the clearing line can now be seen from Huntsville westward as a cold front pushes east across the Tennessee Valley. Temperatures are in the 60s across a large majority of the area except for far NW AL where they have reached the lower 70s. Overnight lows will fall to the low to mid 40s tonight in the wake of the cold front and with clear skies and light winds some frost could form in areas of higher terrain.
133 PM EDT Tue Oct 21 2025 - Showers with gusty winds this morning - Showers with a chance of storms this afternoon into tomorrow - Cooler weather with chances for showers ahead - Showers with gusty winds this morning Latest radar shows bands of showers moving inland from the west. - Cooler weather with chances for showers ahead The strong upper level low will continue to dominate the pattern through most of the week.
(Rest of today through Wednesday) A cold front was moving across Middle TN late this Tuesday morning. Cooler post-frontal air will be felt tonight as temperatures drop into the upper 30s to mid 40s under clear skies. Northwest flow aloft will bring in a dry high pressure system with cool and crisp conditions for midweek.
159 PM EDT Tue Oct 21 2025 A warm front approaches and moves across the area this evening, followed by a cold front late tonight into Wednesday morning.
- Colder temperatures move in later today with overnight lows dropping to the low to mid 40s. (Rest of Today and Tonight) A line of moderate to occasionally heavy rain and embedded thunderstorms is currently tracking east through the area along a cold front that will ultimately bring even cooler temperatures to the region tonight. High will top out in the low to mid 70s today, warmest in the west where clearing is expected by peak daytime heating hours. Overnight lows will fall to the low to mid 40s tonight in the wake of the cold front and with clear skies and light winds some frost could form in areas of higher terrain.
Early this morning, a zonally- oriented cold front is steadily dropping southward across the CWA. Today will be a similar story to yesterday, but noticeably cooler for some. However, onshore flow throughout the day will keep communities near and just inland from the lake a few to several degrees cooler. Lakeside locales will likely fail to make it beyond the lower or middle 70s. High pressure will dominate the region through the week.
An axis of mid to upper-level ridging will arrive today, with weak troughing continuing to push eastward. This high pressure is expected to remain through the forecast period in some capacity. Overnight lows should continue to dip into the 50s with dew points remaining in the low to mid 50s.
Updated at 211 AM EDT Sun Sep 28 2025 - Dry air will move in behind the cold front. By tomorrow the front will push off to the NE brining cooler and dryer weather to the CWA. Temps today will range from the low to mid 80s with cooler temperatures overnight then we've seen over the past few days. This trend will continue tomorrow and into the early part of the week as high pressure and dry air settle in.
Ensemble and deterministic guidance has this ridge overhead through much of the week. By the end of the week, ensemble guidance shifts the ridge axis to the east and most (about 85%) of the ensemble members support the ridge flattening out a bit and a longwave trough approaching from the west, however the strength and timing of this trough are quite uncertain at this time.
/NEW/ /Overnight through Sunday Night/ A broad upper trough will continue to slowly spin across the Desert Southwest through Sunday with a tap into some east Pacific moisture. Otherwise, a light easterly surface wind is expected with high temps in the mid/upper 80s and lows in the low/mid 60s for Sunday night.
The upper level low spinning over the Desert Southwest is expected to open up as it tracks northeast over the Central Plains through today. This will gradually shift upper level flow from the west to south as the upper trough approaches the region. Although southerly winds will usher in warmer air, we will see a slight cool down in temperatures today, especially on the Caprock, due to mostly cloudy skies. Highs will be in the lower to mid 80s on the Caprock and upper 80s off the Caprock.
157 AM EDT Sun Sep 28 2025 Drier weather expected today as weak high pressure builds into the region.
434 AM EDT Sun Sep 28 2025 Low pressure tracks out to sea today.
The upper-level trough that brought last week's rain chances and this weeks drier continues to fill over the Southeast US. Over the western Gulf at the base at the trough and in the mid-levels, a vort max will slowly loose steam as it meanders over the waters today, ever so slightly retrograding to the west.
614 AM CDT Sun Sep 28 2025 - Dry weather and warmer than normal temperatures are expected through the start of the work week. - Disturbed weather over the Southeastern US this week could bring a chance for cooler weather and possible rain later this week. Today and Tonight: Warmer than normal and dry through the period. Ridging surface and aloft will strengthen over the region from the northwest through tonight.
1025 AM EDT Sun Sep 28 2025 Drier weather expected today as weak high pressure builds into the region.
543 AM CDT Sun Sep 28 2025 (Today) Tranquil conditions across the Tennessee Valley early this morning with high pressure at the surface in control of our sensible weather. Daytime highs will again warm into the low to mid 80s -- with a few upper 80s readings possible in portions of northwest and north central Alabama.
The upper low over SE CA this morning will lift NE into nrn AZ today and open up. Dry conditions this upcoming week as we close out September and Monsoon 2025 and move into October with with warming high temperatures as high pressure builds over the area.
635 AM EDT Sun Sep 28 2025 High pressure is expected through the entire week.
545 AM CDT Sun Sep 28 2025 -Mostly clear and sunny skies are expected through the rest of the weekend -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 over the next several days A mostly settled weather pattern is expected across the region over the next several days. As mentioned above, drier conditions are expected under high pressure with little to no rainfall likely through the upcoming week. (12Z TAFS) Widespread VFR conditions are expected as high pressure control the weather pattern.
/Issued 1207 AM CDT Sun Sep 28 2025/ /Overnight through Sunday Night/ A broad upper trough will continue to slowly spin across the Desert Southwest through Sunday with a tap into some east Pacific moisture. Otherwise, a light easterly surface wind is expected with high temps in the mid/upper 80s and lows in the low/mid 60s for Sunday night.
1005 AM EDT Sun Sep 28 2025 High pressure will build southward from eastern Canada through much of the week. A strong cold front will track across the area by the middle of this week bringing cooler and drier weather. Dense fog west of the Blue Ridge has started to lift, with most of it being very low stratus now and some patchy ground fog remaining.
--------------------------------------------------------------- Building high pressure resulting in limited cloud coverage, and combined with light winds has resulted in areas of dense fog this morning, and an Dense Fog Advisory was issued for areas where coverage warrant an advisory. KEY MESSAGES: - Dry and warm conditions continue - Increased cloud coverage Monday ---------------------------------------------------------------- Dry conditions continue Monday as high pressure remains in control. Highs are thus likely to be a few degrees cooler than Sunday, especially south and east of Pittsburgh where cloud cover resides for the majority of the day.
615 AM CDT Sun Sep 28 2025 - Benign and warmer than normal weather is expected through much of this coming week. (Tonight through Monday night) An upper-level trough remains in place over the Southwestern US with scattered showers and thunderstorms ongoing across that region.
743 AM EDT Sun Sep 28 2025 Low pressure tracks out to sea today.
619 AM EDT Sun Sep 28 2025 High pressure will lead to dry and mild conditions through the middle of the week. Cooler temperatures closer to climatological norms will be found for the latter half of the week.
928 AM EDT Sun Sep 28 2025 High pressure is expected through the entire week.
* Strong low pressure will bring additional showers and storms, gusty winds, and cooler temperatures Monday through midweek.
Temperatures will trend rapidly lower by Monday as a cold front and upper level low moves in. Things will switch up today as stronger southerly to south westerly flow begins ahead of the next cold front.
847 AM CDT Sun Sep 28 2025 - Above normal temperatures and dry conditions are expected this week with cooler temperatures near Lake Michigan via lake breezes. Efficient cold air advection occurred behind the departed cold front overnight, particularly over the northwest half of the area. Quigley Issued 300 AM CDT Sun Sep 28 2025 Today through Monday: Upper ridging will build east from the Mid MO River Valley across the nrn Ohio River Valley today and tnt. This will yield light ely winds and cooler temps than yesterday, but still above normal in the 70s. The upper ridge will then re-orient more south to north across IL and WI for Mon-Mon nt while the sfc wind fields do the same.
545 AM CDT Sun Sep 28 2025 - Quiet weather continues through the period as high pressure is expected to remain in place.
626 AM EDT Sun Sep 28 2025 Drier weather expected today as weak high pressure builds into the region.
- A warmer and drier pattern sets up later this week. The upper trough causing the instability and convection today moves east into the Rockies tomorrow bringing an end to rain chances. Showers do not move east with the trough because mid level moisture remains to the west causing a dry trough passage in the Permian Basin.
- Very warm, well above normal temperatures, trending a little cooler late week.
A bit cooler through the overnight hours with post-frontal drying keeping skies clear and dewpoints in check. Configuration of the low-level anticyclonic flow field lends potential for warmer air to spill into southern Lower Michigan from the Upper Midwest Monday evening.
12Z upper air maps show an upper trof of low pressure at high altitudes positioned over the eastern U. Within the trof axis, Tropical Storm Imelda lifts northward over the northwest Bahamas through Monday. The upper trof looks to remain in place into the early half of the upcoming week which favors a dry northwest flow over the local area as we open up the new week.
1212 PM CDT Sun Sep 28 2025 - Quiet weather continues through the period as high pressure is expected to remain in place.
Currently, deep layer ridging remains in control of the regional weather. Skies are clear, with temperatures currently running into the low to mid 80s. The region remains under the influence of high pressure at the surface.
Afternoon RAP analysis and GOES satellite imagery reveal barely a cloud across the entire central CONUS underneath a very dry ridge. More of the same is expected tomorrow (Monday) with daytime temps reaching the upper 70s to low 80s as the ridge axis shifts overhead.
A transition to southwest flow aloft may bring some mid to high level clouds tonight, although mainly dry and mild temperatures look to continue with ridging still aloft. Areas with these warmer overnight lows could see some patchy fog form if winds can relax some. Southwest flow aloft further builds into the area on Monday with a weak warm front setting up in central to northern North Dakota.
Tropical Depression 9 continues to try to organize over the Bahamas while another area of low pressure is seen on visible satellite over the central Gulf. High pressure dominates much of the central and eastern CONUS. The next few days will be very quiet with s/w ridging over the area.
124 PM EDT Sun Sep 28 2025 High pressure is expected through the entire week, which will bring a prolonged period of dry weather.
Otherwise we remain primarily under the influence of the upper ridge that extends from south Texas to the Great Lakes region and any unsettled weather remains well to the west.
215 PM CDT Sun Sep 28 2025 - The warmer than normal conditions will continue through the week with only a slight cool down toward the weekend.
The Northern Ranchlands could see slightly cooler than average low temperatures in the upper 60s.
120 PM EDT Sun Sep 28 2025 High pressure is expected through the entire week, which will bring a prolonged period of dry weather.
Updated at 1221 PM CDT Sun Sep 28 2025 - Cooler weather is expected tomorrow with meager rain chances across the CFWA. (This evening through Monday) The upper level trough over AZ is expected to begin trekking east over NM with some amplification and negative tilting over southern NM. As such, lows tonight will stay in the high 50s and low 60s across the CWFA, and highs tomorrow to stay in the high 70s to low 80s, with localized mid-80s spots below the caprock. Otherwise, any breaks in the high- cloud shield, especially coupled with resultant outflow boundaries from convection in the NM plains can influence local updrafts which may turn into high-base convection, but confidence for that is currently low.
High pressure centered over the region will maintain dry and stable conditions this taf period. The post frontal northeast winds will produce cooler lake augmented temperatures in the low to mid 70s for the lakeshore areas of the Thumb and Tri- Cities. This should allow for a decent cool off, so will lean on the cooler side of guidance with mid 40s across the north and low to mid 50s across the south. Ridging aloft and at the surface carries through the early week period with a blocked upper level pattern.
* Mild/warm start to the week before turning much cooler with stretch of dry weather continuing into October. High pressure settling over central PA tonight will again favor radiational fog into early Monday morning.
Hardly any clouds in the sky today as high pressure continues to sit over us through the next few days as we stay in this blocking pattern. Through the end of the forecast period we will be mostly dry and warmer than average. Ensemble cluster analysis shows a trough west of the area with tropical disturbances affecting the far southeast US. Our area looks to be caught in between with high pressure in control.
- Slightly cooler temperatures on Monday behind a departing upper- level trough. - Drier conditions return late week as another upper-level ridge moves overhead. Today, the upper level ridge breaks down and moves east as the upper level low pushes into the four corners region. For Monday, The upper level low is expected to lift through the Rocky mountains and Intermountain West. Winds will be a little breezy as well Monday as the upper level low pushes through the Intermountain West tightening the pressure gradient at 700mb and lower.
High pressure and a very dry air mass (PWAT of 0. The sunshine, combined with light south winds, allowed temperatures to warm into the lower to middle 70s at most locations. Have continued to side with the cooler guidance for low temperatures, with readings ranging from the upper 30s/lower 40s in the cool spots of north central WI, and 40s to lower 50s elsewhere. A weak cold front drops south across the region Monday night, with greater potential for patchy/areas of fog as a shallow cooler air mass arrives and winds become light from the east to northeast. Canadian high pressure will ridge across the Great Lakes region through the rest of the week, and will be slow to shift east due to the blocking influence of a couple tropical systems in the western Atlantic.
/NEW/ /Today through Monday Afternoon/ Upper level ridging will continue to dominate the regional weather as the closed low remains overtop the Desert Southwest. A fetch of high moisture will continue to make its way east- northeast around the base of the low and apex of the ridge, spreading across North and Central Texas.
1244 PM CDT Sun Sep 28 2025 -Mostly clear and sunny skies are expected through the rest of the weekend -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 over the next several days A mostly settled weather pattern is expected across the region over the next several days. As mentioned above, drier conditions are expected under high pressure with little to no rainfall likely through the upcoming week.
241 PM EDT Sun Sep 28 2025 Strong Canadian high pressure builds south over the Great Lakes region through the middle of the week. The high will shift towards the Northeast region by the end of the week. Quiet weather continues as high pressure remains overhead through the forecast period. Strong Canadian high pressure will move overhead early this week leading to continued dry weather.
204 PM EDT Sun Sep 28 2025 High pressure builds south from eastern Canada through much of the week. A strong cold front will track across the area by the middle of this week bringing cooler and drier weather. Abundant sunshine and warm temperatures are the main story for today as high pressure builds into the region in wake of a weak frontal passage this morning. It is important to note that this high will protect our region from any direct impacts associated with TD9 as that system approaches the Southeast coast.
High pressure builds in from the north behind this front and has brought a shift in the winds to a more north-northeast direction.
