.KEY MESSAGES...
- Temperatures will warm into the mid to upper 90s this afternoon and through the early part of next week as oppressive upper level ridge strengthens over the region.
- Expect daily hot and dry conditions with less than 5 percent chances of rain each day under high pressure regime.
- Lower than normal daytime humidity will keep heat indices capped in the upper 90s each day. Continue practicing heat safety for those outdoors working, at sporting practices, or otherwise being active outdoors.

.SHORT TERM... (Today through Sunday night) Issued at 1239 AM CDT Fri Sep 12 2025
Continuing with the persistence forecast messaging through the short term forecast. High pressure strengthens over the region today and Saturday. Sunday, upper trof sweeps into the lower Plains states, breaking down the ridge slightly, but subsidence is set to remain in place.
Thus, increasing heights aloft will allow high temps today and Friday. Dry air continues advecting into the region. The combination of this airmass and increasing heights will give plenty of room for daytime heating to maximize and highs in the mid to upper 90s can be expected.
The lapse in upper high on Sunday will allow increased cloud cover but no rainfall. Even so, highs will persist in the mid to upper 90s area wide. Humidity will remain low resulting in daytime minimum RH values 30 to 45 percent and keeping heat indices in the upper 90s thru the period.

.LONG TERM... (Monday through Friday) Issued at 1239 AM CDT Fri Sep 12 2025
The dry, oppressive heat only continues into the longterm period. High pressure will remain well within control of the weather pattern, bringing about hot and dry conditions to the weekend and into the start of next work week. Temps will top out in the mid to upper 90s each day with daily heat indices in the mid to upper 90s as well.
Much of the same hot ridge pattern is seen into Monday. Guidance is now beginning to agree on upper trof moving into eastern seaboard Tuesday before a cutoff low forms and retrogrades west towards the north central Gulf. If this does occur, it likely won`t impact us much here thanks to surface high and ambient dry airmass.

.AVIATION... (12Z TAFS) Issued at 621 AM CDT Fri Sep 12 2025
Outside of areas of patchy fog, VFR conditions are ongoing and expected to prevail past the end of the forecast period. Winds will be light and generally out of the east and southeast.
&&
.MARINE... Issued at 1239 AM CDT Fri Sep 12 2025
Winds continue to be progged to prevail from the east to east northeast through the period as high pressure continues ridging into the northwest Gulf. Periods of enhanced easterly flow and seas will develop over outer 20 to 60 nm waters as the gradient tightens with the passage of waves.
Dry air and high pressure will keep precipitation chances to a minimum.
&&
.FIRE WEATHER... Issued at 1239 AM CDT Fri Sep 12 2025
Hot and dry conditions with breezy, variable winds to be expected today thru the start of next work week. High pressure over the region strengthens from today through Sunday allowing high temps to drive into the mid to upper 90s each day. Surface mixing is expected each afternoon with daytime RH minimums in the 30 to 45 percent range.
