.NEAR TERM... (Through Sunday) Issued at 1235 AM CDT Sun Sep 7 2025
After another cool start to the day southeast winds and quite a bit of solar insolation should allow temperatures to warm into the upper 70s to middle 80s across the area Sunday afternoon.
Some upslope flow and an upper shortwave dropping southeast out of the central Rockies will produce scattered showers and thunderstorms this afternoon across the High Plains of Colorado. This activity will then propagate southeast toward northwest Oklahoma this evening. Although an overall weakening trend is expected with this activity as if moves out into the Plains, a modest llj will aid in keeping some chance of this activity making a run at far northwest Oklahoma late tonight. Otherwise, increasing cloud cover and south winds should keep overnight low in the 60s areawide.

.SHORT TERM... (Sunday night through Tuesday night) Issued at 1235 AM CDT Sun Sep 7 2025
As we move through the day Monday, upper shortwave may aid in allowing convection to continue across mainly northwest into north central Oklahoma. With daytime heating more robust convection may develop across Kansas into northern Oklahoma Monday afternoon. With modest instability and deep layer shear can not rule out a few strong to possibly severe storms.
Pressure falls across the High Plains will tighten the pressure gradient across the Plain states with some stronger south winds on Monday. Although the cloud cover may mitigate the response you would otherwise expect with the stronger south winds in afternoon highs, still looks like much of the area will warm into the 80s Monday afternoon.
Another shortwave moves out of the Rockies Monday night and modest llj may bring another chance for a few showers/storms to parts of the area Monday night into early Tuesday morning.
Otherwise, we begin to see upper level ridge begin to build northeast out into the Plains Tuesday. This will begin a warmer/drier period as we go through the week.
&&
.LONG TERM... (Wednesday through Saturday) Issued at 1235 AM CDT Sun Sep 7 2025
As we move though the middle and latter part of the upcoming week, upper ridge will dominate the weather across Texas northward through Oklahoma. Main storm track will remain to our west and north around this ridge. From Wednesday into at least the first half of next weekend looks to remain dry with temperatures back around or slightly above normal for early/mid September with upper 80s and low to middle 90s.

.AVIATION... (18Z TAFS) Issued at 1229 PM CDT Sun Sep 7 2025
Low clouds and fog from this morning continues to burn off and expect VFR conditions for the rest of the period, though scattered mid to high clouds are likely to continue. Winds will remain from the southeast, decreasing slightly overnight before increasing to 10-15 knots by mid to late Monday morning.
