.KEY MESSAGES... Updated at 1235 PM CDT Sun Sep 14 2025
- Hot/above-normal temperatures continue into next week.
- Scattered showers and storms are possible today with the potential for a few strong to severe storms mainly across northwest Oklahoma this afternoon and evening. Large hail and damaging winds remain the primary hazards.
- A mid-week cold front will bring increased rain chances and near- normal temperatures.

.NEAR TERM... (Through Sunday) Issued at 1232 AM CDT Sun Sep 14 2025
A passing negatively tilted shortwave trough and subsequent lee troughing this morning will help to aid warm air advection showers and storms eastward across West Texas and into western Oklahoma and western north Texas around, but mostly after sunrise. Increased cloud cover may inhibit daytime heating, along with cooler temperatures with the passing surface trough, especially across western Oklahoma. Highs today will still remain mostly above normal in the 80s to lower 90s.
Peeks of sunshine with clearing clouds from west to east during the afternoon hours may result in scattered showers and storms. Ample MLCAPE above 1000 J/kg and modest shear around 20-30 knots will support a strong to severe storm or two capable of large hail and damaging wind gusts. This diurnally driven convection will begin to diminish with the setting sun and cooling surface temperatures late tonight.
&&
.SHORT TERM... (Sunday night through Tuesday night) Issued at 1232 AM CDT Sun Sep 14 2025
There is a low signal for isolated showers and storms across western north Texas Monday morning. Above normal temperatures will continue Monday in the upper 80s to mid 90s. The weak shortwave lingering over central and eastern Oklahoma coupled with daytime heating may result in scattered showers and storms. The potential remains very low at this time with no significant mention in PoPs.
In the wake of the departing upper wave, the next positively tilted trough axis will dig into the Mountain West Tuesday. Southerly surface flow will give way to once again warmer than average temperatures, similar to Monday. By Tuesday afternoon, strong daytime heating coupled with weak lift ahead of the approaching trough may result in some developing convection across northwest Oklahoma. Shower and storm chances will persist overnight across much of northern Oklahoma with the strengthening surface trough and increasing low-level jet.
&&
.LONG TERM... (Wednesday through Saturday) Issued at 1232 AM CDT Sun Sep 14 2025
Shower and storm chances will continue Wednesday into Thursday with the passing trough axis and cold front. The cold front Wednesday night into Thursday will bring "cooler" near normal temperatures to the forecast area with highs mostly in the 80s. Model solutions begin to diverge towards the end of the week and into the weekend with the potential for another surge of cooler air into Oklahoma, which may keep the seasonal temperatures sticking around for a bit.

.AVIATION... (18Z TAFS) Issued at 1235 PM CDT Sun Sep 14 2025
Scattered showers and embedded thunderstorms continue to move across the western third/half of Oklahoma early this afternoon. Some of the heavier showers/storms may reduce visibility into the MVFR category, especially near CSM. Stronger storms are expected to form near a weak frontal boundary in the Oklahoma Panhandle/northwestern Oklahoma this afternoon. MVFR conditions are possible with some of these storms along with a risk of hail and strong, gusty winds. After 3Z Sunday, isolated showers may remain with mainly VFR conditions. A southerly wind is expected to prevail through 18Z Monday, except near thunderstorms.
