217 PM EDT Fri Aug 1 2025 High pressure remains in control through midweek before a frontal system approaches toward week's end. A frontal boundary continues to shift south of the area while high pressure builds in from the northeast. A longwave upper level trough remains across much of the east coast of the US and up into eastern Canada. This will be the first of several cooler nights coming up. High pressure settles over the area on Saturday with sunny to mostly sunny skies expected. Given the cooler airmass, temperatures likely only reach the low 80s.
- Much cooler conditions expected the next few days with highs in the 70s-80s and lows in the upper 50s to 60s.
1224 PM CDT Fri Aug 1 2025 Updated at 1221 PM CDT Fri Aug 1 2025 - A weak cold front helps bring near to slightly below normal highs and low (10-30%) rain chances over the Davis Mountains and Permian Basin/Low Rolling Plains this afternoon.
(This evening through Saturday) Water vapor imagery this morning paints a fairly active upper level pattern characterized by a trough swinging across the Great Lakes as the ridge over the southeast begins to weaken. To our west, a stout upper level ridge is beginning to take shape. At the surface, RAP analysis depicts a weak cold front slowly moving south across the state. The weakening ridge will lead to slightly cooler highs, generally in the upper 80s, and knock a few degrees off our heat indices, generally in the 95-100F range.
On Saturday, a lee-side trough/dry line shifts east across the area during the afternoon. Across the higher terrain, urban corridor, and nearby plains, westerly winds will bring slightly drier air.

A bit warmer on Saturday (highs near 80F) as the airmass gradually moderates into the back-half of the weekend. Precipitation-free weather persists as a low-level anticyclone builds eastward, into Lower Michigan.
The front will continue to slowly sag south into our forecast area on Saturday as the ridge breaks down and the upper level trough continues to drop into the southeastern US. With the ridge moving out and moisture on the increase, coverage will be much more widespread, especially across our AL/GA counties.
Issued by National Weather Service Albany NY 230 PM EDT Fri Aug 1 2025 High pressure will remain over the North Country through the weekend. Saturday will be very similar to today with dry and cooler conditions once again.

(This evening through Saturday night) For the first day in August, the temperatures can certainly be much higher with average values in the lower 90s, where we are making an effort just reach the lower 80s as of the latest 18Z obs. Further aloft, the periphery of the main H500 anti-cyclonic feature center over SE Arizona and its series of ridge rollers continues to produce diurnally driven convection development over the NM/CO high terrain. Going into the day tomorrow, latest 01/12Z model and numerical data shows an H500 negative tilted trough moving east into the central Rockies midday. This broad enhance area of lift reaching the high terrain and increased effective wind shear will result in loose cluster multi cells and/or linear segmented thunderstorms to form across eastern Colorado and western Kansas.
Highest chances will be for southwest Florida as well as the interior, as this is where the highest moisture resides. and the ridge shifts northward a bit.

Broad high pressure has settled over the region and will remain over the Northeast U. High pressure will remain overhead through the period, with mostly skies and clear/cool nights.
High pressure remains in place over the state of Florida, allowing for southwesterly to westerly flow to continue across the region.
There is a 15-30 percent chance of more showers and thunderstorms over the higher elevations Saturday afternoon and evening.
This isn't surprising though considering that we remain heavily locked down in a mean layer ridge, which is suppressing activity. In the meantime, low level ridge will maintain light to occasionally gentle east to southeast breezes. A weak western arm of an Atlantic ridge will remain across South Florida and the Keys over the next couple of days. The ridge will lift northward into Central Florida this weekend.
215 AM CDT Sat Aug 2 2025 - Stagnant weather pattern remains in place with a strong high pressure over the region trapping smoke at the surface. - A Rex blocking pattern sets up over the Northland leading to off and on rain and thunderstorm chances through the work week.
On Saturday, a lee-side trough/dry line shifts east across the area during the afternoon. Across the higher terrain, urban corridor, and nearby plains, westerly winds will bring slightly drier air. This will bring slightly cooler air and drier into the area.
124 AM EDT Sat Aug 2 2025 High pressure will remain overhead for at least the next 4 to 5 days. Big bubble, no trouble! Broad high pressure has settled over the region and will remain over the Northeast U. High pressure will remain overhead through the period, with mostly skies and clear/cool nights.
- Relatively cooler temperatures will bring some relief to the area. This, in combination with the southward progression of a frontal boundary, will bring some cooler temperatures to the area. Current high temperature estimations are mostly in the upper 80s, with a few locations expected to creep into the low 90s. Even with the cooler temperatures, diurnal convection will still develop through the day.
Rain chances continue through much of the forecast period as a broad mid/upper trough lingers over the eastern U. Discussion: A cooler and drier air mass has moved into the area, with obs showing dewpoints in the 60s and a NE wind. The inverted trough will be the focus for showers and a few thunderstorms today, although instability will be limited with abundant cloud cover in place. The low to midlevel flow remains weak, so slow-moving showers could pose an isolated flooding threat.
There is a compact low pressure circulation spinning over northwest South Dakota. The rest of the 7-day consists of this semi-flat/dirty ridge, almost zonal flow aloft, pattern where (almost daily) diurnally driven convection could impact (some portion of) the CWA.
1222 AM CDT Sat Aug 2 2025 Updated at 1219 AM CDT Sat Aug 2 2025 - A cold front and a mid-level disturbance brings low (10-30%) rain chances across our region later this afternoon and into the evening. - Temperatures start to climb as a ridge of high pressure builds overhead.
While there is lower confidence in the exact timing of the smoke clearing out, cloud cover should diminish overnight into Sunday morning with low temperatures in the lower 60s for the city and 50s away from Chicago. The clearer skies will allow temperatures to warm up on Sunday afternoon into the lower 80s, with upper 70s along the shoreline as onshore winds help keep it slightly cooler.
113 AM EDT Sat Aug 2 2025 Cooler and dry weather will persist through the weekend. KEY MESSAGES: - Cool and dry conditions prevail today --------------------------------------------------------------- Dry and quiet weather is expected today due to high pressure. KEY MESSAGES: - Quiet and dry conditions continue into Sunday - Rocky Mountain wildfire smoke may linger ---------------------------------------------------------------- Confidence remains high that dry and quiet weather will likely continue into Sunday under high pressure. Hazy conditions from Rocky Mountain wildfires, which have affected the Great Plains, may reach the region late Sunday morning with the progression of a weak trough.
202 PM CDT Mon Sep 22 2025 - Welcome to the Autumnal Equinox a few moments ago at 119 PM CDT - Summer heat lingers beyond today into tomorrow with an encore mention of triple digit heat indices Tuesday with higher RH and perhaps some compressional heating ahead of the cold front.
Once the thunderstorm threat passes tonight a ridge of high pressure will settle into northern and central SD. This will bring some cooler morning readings with at least a small chance of a few locations sneaking into the upper 40s near highway 14. Cooler high pressure builds south and brings about a seasonally warm day on Tuesday with relatively light winds.
However, the western periphery of a low level ridge will main enough influence to keep showers and storms more in the isolated/summertime variety across most of our area through Tuesday. Midweek: The pattern will begin to shift beginning late Tuesday as an upper trough builds from the Great Lakes region into the Mid- MS Valley and Southern Rockies.
- A cold front will move into North Texas Tuesday evening with increasing storm chances.
209 PM MDT Mon Sep 22 2025 -Breezy northerly winds and showers/storms across the area tonight -Dry with temperatures at or above normal the rest of the week Upper air analysis shows a broad trough across the northern Plains into the WY Rockies, swinging southeastward into the central Plains. The cold front will slide southward across the CWA this evening as the upper low swings into northern CO/western Neb tonight. Strong upper ridging centered over the western CONUS will build into the central Plains. With today's upper low moving into the eastern CONUS and another upper low near then central CA coast, an omega block will set up.
In eastern North Dakota, northwest Minnesota, and west central Minnesota, look for generally quiet weather with light winds and warmer than average temperatures.
158 PM EDT Mon Sep 22 2025 Isolated showers and storms possible west of the Blue Ridge this afternoon. Low pressure over the northern plains and upper Midwest will track the Great Lakes and lower Missouri Valley by Tuesday. Max temps Tuesday could have more of a gradient with a bit warmer values in the Piedmont generally mid to upper 80s and cooler in parts of the mountains given cloud cover/precip, generally in the mid 70s to low 80s.
124 PM EDT Mon Sep 22 2025 High pressure, dry conditions, and turning hot through mid-week. Weak high pressure continues to the linger to our north, driving some northeast winds down into our area.
Expect high temperatures in the middle 80s to around 90 this afternoon (a few degrees cooler atop the higher elevations).
222 PM MDT Mon Sep 22 2025 KEY MESSAGES: - Gusty northwest winds and slight chances for rain continue through this afternoon behind the cold front passage. WEATHER PATTERN OVERVIEW: A narrow upper trough is working its way though east through central Montana. This trough is expected to push south then east, forming a partially closed low. The upper ridge of the system will extend north into Montana by midweek with fast zonal flow over Canada. Cooler temperatures will also drop south behind the front, before warming into midweek with the building ridge.
As we reach the middle of the week, there is a large consensus on a quickly dropping mid to upper level trough becoming cut off from the parent upper level flow.
118 PM EDT Mon Sep 22 2025 High pressure centered along the East Coast this afternoon will move offshore tonight.
120 PM MDT Mon Sep 22 2025 - Weather system brings precipitation, cooler temperatures, and breezy northwest winds to the region today. Current analysis shows upper level troughing bringing a band of showers to south central MT and north central WY. As high pressure and drying quickly build in from behind, the pressure gradient across south eastern MT is expected to tighten, resulting in breezy conditions for this area through the afternoon today. As the western portion of the region clears today, this will allow for cooler overnight temperatures, giving areas of Wheatland Co about a 30-60% chance of a frost Tuesday morning. The main story for the remainder of the period will be warm and dry conditions as ridging builds in over the western US and stays put.
Models and ensembles are back and forth with how far north midweek low pressure system tracks.
Southwesterly flow aloft continues over the region, with a cutoff low still churning off of the southern California Coast and a ridge anchored over northern Mexico.

The mid week period will feature a building mid level ridge initially followed by subtle height falls and increasing moisture from the southwest.
An upper-level trough situated over Lake Superior will prog slowly to the northeast over the next several hours. Which will also maintain chances for overnight fog as temperatures fall to dew points with efficient radiation cooling and a lack of surface winds under high pressure. This lowering could last a few hours.
Radar and satellite imagery this morning show a large are of showers and thunderstorms moving through Indiana and western Ohio, tied to an upper-level trough progressing across the Great Lakes and Midwest.
