.NEAR TERM... (Through Saturday) Issued at 1245 AM CDT Sat Sep 13 2025
Another warm and low-impact weather day is expected across Oklahoma and north Texas to begin the weekend. A broad western trough will continue its slow eastward march through the day. With subtle height falls and increasing cloud cover, high temperatures will run a few degrees "cooler" compared to Friday (especially across northwestern Oklahoma). Another afternoon with an occasionally gusty south wind is also forecast in response to weak cyclogenesis to the west.

.SHORT TERM... (Saturday night through Monday night) Issued at 1245 AM CDT Sat Sep 13 2025
While most of Saturday night will be quiet/dry, a few showers and thunderstorms are possible towards daybreak Sunday across western Oklahoma.
The upper trough and associated surface reflection/front will be further east by Sunday. While the focus for precipitation during this time will extend from the eastern Texas Panhandle into southwestern Kansas, at least scattered coverage of showers and thunderstorms appears probable across western Oklahoma and western- north Texas with time on Sunday. Given increasing upper-level wind fields/shear and a ribbon of instability progged, a few strong-to- severe thunderstorms will be possible during the afternoon and evening hours as well.
The aforementioned upper trough looks to lift northward on Sunday night, returning the area towards more dominant dry and continued warm weather by Monday. Temperatures will continue to run in the upper-80s to low-90s during the afternoon/evening.

.LONG TERM... (Tuesday through Friday) Issued at 1245 AM CDT Sat Sep 13 2025
Early signs point to continued "warm" (by mid-September standards) and mainly dry weather next week. The upper air pattern across the CONUS remains somewhat muddled in grand ensemble guidance, with potential for an upper trough to migrate across the Northern Plains during the period. Low chances for rain/storms are currently advertised on Wednesday into early Thursday across northern portions of Oklahoma, in response to a trailing surface front from this feature. Otherwise, temperatures will likely remain in the 80s to low-90s, running +5-10 degrees compared to seasonal average.

.AVIATION... (12Z TAFS) Issued at 545 AM CDT Sat Sep 13 2025
Clear skies early this morning will be replaced by scattered to eventually broken high cloud cover as cirrus overspreads the area. With that said, VFR conditions continue. Winds will initially increase out of the south-southwest this morning before shifting back to south-southeast in the afternoon/evening. Shower/storm chances will increase in northwest and far west Oklahoma late in the TAF period, though better chances will likely be confined to the timeframe after 12Z tomorrow.
