.SHORT TERM... (Today through Tuesday night) Issued at 1229 AM CDT Mon Sep 15 2025
Thunderstorms continue across the east central Texas Panhandle with the primary hazard being heavy rainfall leading to nuisance flooding or flash flooding. Storms are moving relatively slowly so that is adding a bit to that potential. Once that activity weakens/dissipates over the next few hours, clear skies and light winds are expected the rest of the night. This environment will promote the potential for at least patchy fog to develop near sunrise. The fog may be dense at times so be careful if driving through fog this morning. Fog should burn off a couple of hours beyond sunrise.
Weak upper level flow should remain over the Panhandles today as we will be in-between systems so a relatively calm day is in store for the region. Temperatures should warm up into the mid to upper 80s with perhaps a few 90s mixed in and winds will be light and out of the south. The only weather concern for today will come with the potential for isolated thunderstorms to develop by mid to late afternoon. Subtle surface convergence combined with areas reaching convective temperatures may be enough to generate diurnally driven storms today. The 15/12z CAMs are hinting at this activity so have included very low chances for storms given the above mentioned scenario. If any storms do form, the environment is marginal for severe storms but if a storm can remain attached to any boundaries, cannot rule out a strong to severe storm. Main hazards would be large hail and damaging wind gusts if the storm could become robust enough. The storm threat should diminish after sunset due to the lack of synoptic support.
H300 troughing will dig south over the Intermountain West throughout the day on Tuesday. For the Panhandles, mostly dry conditions are forecast during the daytime hours with highs in the 80s. A disturbance rounding the base of the trough should provide ample lift to generate showers and storms that will move east/southeast. The thunderstorm activity may start across the higher terrain to the west before moving across the area through the night into Wednesday morning. Severe storms are not expected with this activity, but moderate to heavy rain may be possible with some of the stronger storms.

.LONG TERM... (Wednesday through Sunday) Issued at 1229 AM CDT Mon Sep 15 2025
A low pressure system should be located over the Rockies across central/northern Colorado to start the day on Wednesday. In fact, there could be showers or storms ongoing across the forecast area to begin the day. The rain chances will continue throughout the day as upper level support will remain in place to generate additional rainfall and ample mid level moisture should linger over the region. With cloud cover throughout the day and potential rain chances, highs on Wednesday may need to be decreased and the NBM 50th percentile is a bit lower than the deterministic NBM. Will keep temperatures as is for now since the difference is marginal at this time. A cold front should pass over the region on Wednesday into early Thursday morning. This will lead to cooler temperatures on Thursday as rain chances continue for the Texas and Oklahoma Panhandles. Shower and thunderstorm activity may get pushed to the south and east of the CWA by early Friday morning as the trough moves just to the east of the area, but that potential varies in the latest model guidance.
In general, the upper level pattern varies tremendously in the model guidance Friday through next weekend. A weak ridge does look to attempt to build over the Desert Southwest towards west Texas during this time. Troughing further east may keep the Panhandles in northwest flow which could lead to continued rain chances, but other models have the flow more northerly which would not be as favorable for rain chances. Even with the model disagreement, it appears temperatures should be able to rebound back into the 80s going into next weekend.

.AVIATION... (06Z TAFS) Issued at 1229 AM CDT Mon Sep 15 2025
VFR conditions are currently forecast with this TAF cycle. Patchy fog is possible at all sites starting around 09z. MVFR or lower visibility is possible at all sites, but confidence is not high enough to mention at this time. Amendments may be required if fog develops at the terminals. Fog will clear out quickly after sunrise this morning. Isolated storms will be possible at KGUY/KAMA this afternoon through early this evening. Chances are only around 10-15 percent so have not included any mentions in the TAFs. Winds will be light overnight but will become south to southeasterly around 10 kts with mostly clear skies.
