KEY MESSAGES

Updated at 1205 PM CDT Sat Oct 10 2026

- Dry weather continues through the weekend with warmer than normal temperatures.

- Isolated to scattered showers and thunderstorms are possible each day during the work week.

SHORT TERM

(Tonight through Sunday night) Issued at 105 PM CDT Sat Oct 10 2026

The remnants of Hurricane Isaias are disrupting the upper air pattern over the southeastern quadrant of the country with some unusual flow over TX. Regardless of the winds observed by regional balloons, satellite imagery suggests strong subsidence over TX with only scattered cumulus field across South TX. This cloudiness has formed where the low level flow has turned back to southeasterly south of our CWA. This southeasterly flow will return to South-Central Texas during the next 24 hours or so. This will bring moister air back over the region. We should see more cloudiness overnight tonight. The strong subsidence will likely keep Sunday rain free. Sunday night expect cloudy skies to spread over most of the CWA and along with that warmer low temperatures.

LONG TERM

(Monday through next Saturday) Issued at 105 PM CDT Sat Oct 10 2026

Monday an upper trough along the west coast will begin to move inland and turn the flow over TX to the southwest. With moisture in the vertical increasing, we will begin to see showers develop during the afternoon. This pattern will repeat each day through Wednesday. Chances for rain will be confined to the Coastal Plains and I-35 Corridor. In addition to the rain chances, temperatures will increase into the middle of the week. With the higher humidity heat indices will push back above 100 degrees for most of the CWA. Models continue to move the upper trough across the central Rockies and into the Plains bringing a cold front. However, today they are a bit drier, and we have lower POPs and QPF for the latter part of the week. Despite the lower rain chances, temperatures are lower behind the front for Friday and Saturday.

AVIATION

(18Z TAFS) Issued at 105 PM CDT Sat Oct 10 2026

VFR conditions will continue at area TAF sites through the afternoon and into early this evening. With low-level moisture returning to the region, we expect to see a round of MVFR clouds develop Sunday morning along the I-35 corridor after 11Z. TEMPO groups have been included for the I-35 sites between 11-15Z and will monitor subsequent model runs in case the onset of MVFR clouds trends earlier. We have also included a mention of TEMPO MVFR cigs out west at DRT with a later arrival in the 13-16Z time frame. Shallow moisture should mix out quickly by late morning as southeast winds increase, with gusty conditions at DRT.
