DISCUSSION

Issued at 136 AM CDT Tue Aug 25 2026

Hot and dry conditions continue through at least the middle of the week, but we will FINALLY have something to talk about. The ridge still continues over the area, with a center somewhere near the Four Corners. High temperatures will still be in the 90s along the coast, nearing 105 across the Brush Country. A fairly dry air mass will help regulate our heat index values, keeping them generally in the range of 105-109 across the Brush Country, but expect we could see heat index values from 110-113 over isolated location across the Coastal Plains and Victoria Crossroads. Expect conditions to be a few degrees warmer Wednesday, so a Heat Advisory may be needed. Remember that cumulative heat stress can result in a higher risk of heat illness. Please use caution if you are spending time outside. Drink plenty of water and take breaks. Don't forget to look before you lock!

The ridge will finally weaken a bit on the eastern side Wednesday night and Thursday, allowing more moisture to move into the area. Meanwhile, a mid-level trough will slide to the south, sneaking in under the ridge and introducing a low (15-40%) chance of showers and thunderstorms, mainly east of 281. With the increasing clouds high temperatures across the Victoria Crossroads and along the coast should be a few degrees cooler. While it may only be 2-3 degrees, we will take it!

AVIATION

(12Z TAFS) Issued at 612 AM CDT Tue Aug 25 2026

Brief MVFR conditions across VCT and ALI this morning are expected to lift to VFR around 14Z. These conditions are expected to develop once again overnight, mainly after 08Z Wednesday. Otherwise, VFR conditions will persist across S TX through the TAF cycle. S-SE sustained winds will generally be around 15 knots or less with occasional gusts to 20-25 knots this afternoon.

MARINE

Issued at 136 AM CDT Tue Aug 25 2026

Expect light to moderate (BF 2-4) onshore breezes will continue through the period, with occasional fresh (BF 5) breezes possible during the late afternoon/evening hours, especially south of Port Aransas. Seas are expected to remain around 2-3 feet. Rain chances will remain near zero through the middle of the week. Mariners should take steps to prevent heat illness as hot temperatures continue.

FIRE WEATHER

Issued at 136 AM CDT Tue Aug 25 2026

ERC values have increased across the Brush Country to the 90-96th percentile, with most of the rest of the area in the 70-89th percentile. Humidity values will continue to be low, with minimum RH values below 34% over the Coastal Plains and Brush Country. Winds will remain fairly light, but given the hot temperatures, low relative humidity, and high ERC values, have issued another Fire Danger Statement for most of the area through this evening. Should winds increase more than anticipated, a few locations could experience critical fire weather concerns.
