KEY MESSAGES

Updated at 1211 AM CDT Thu Mar 19 2026

- Elevated fire weather conditions over the Brush Country and inland Coastal Plains daily through Monday.

- Dry weather and warming trend continue through the upcoming weekend.

DISCUSSION

Issued at 1153 AM CDT Wed Mar 18 2026

The forecast period will be largely dominated by the record- breaking H5 ridge (~595 dam) currently positioned over the SW US. Although the ridge will slightly shift east and de-amplify late this week into the upcoming weekend, its influence will remain strong over the area, supporting dry and seasonably warm weather. At the surface, SErly flow will prevail through the forecast period, as high pressure remains positioned over the Gulf and thermal lows develop daily over the higher terrain to our west. The presence of the ridge and northward displacement of the jet stream/storm track will keep any fronts north of the area.

Temperatures will warm through the week and into the weekend as 850mb temps warm almost 10 degrees (from 8 to 18C). SErly flow will maintain an E-W gradient with highs ranging from the 70s near the immediate coast to the mid 90s over the Interior (with 20-30% chances of triple digit highs over the Brush country by the weekend). Fortunately relatively dry conditions and (at least through Friday)and light winds overnight will foster efficient radiational cooling with overnight lows generally in the 50s through the end of the week.

AVIATION

(06Z TAFS) Issued at 1211 AM CDT Thu Mar 19 2026

MVFR to IFR VSBY's expected during the morning hours at VCT/CRP/ALI otherwise, VFR conditions prevail. Winds will be light and variable out of the south to southeast.

MARINE

Issued at 1153 AM CDT Wed Mar 18 2026

A gentle to moderate (BF 3-4) south to southeasterly breeze will persist through this weekend. Winds will occasionally strengthen to a fresh breeze (BF 5) over the bays and nearshore waters south of Port Aransas this weekend. No rain chances are expected at this time.

FIRE WEATHER

Issued at 1153 AM CDT Wed Mar 18 2026

Although winds will remain generally below critical criteria, occasional wind gusts around 20 mph in combination with relative humidity of 15-30% and critically dry fuels over the Brush Country and inland Coastal Plains, will promote elevated fire weather concerns today. Similarly elevated conditions will persist through the week and into the weekend with fire danger statements likely for the Brush Country each day.
