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

(06Z TAFS) Issued at 136 AM CDT Tue Aug 25 2026

VFR conditions will prevail through the TAF cycle. There is a 20-30% probability of brief MVFR VSBYs and/or CIGs at VCT and ALI early Tuesday morning, mainly after 08Z to around 14Z. This has been occurring over the last several mornings, thus will keep with persistence and include a TEMPO to address the brief MVFR conditions. S-SE winds 10-15 knots gusting to 20-25 knots expected Tuesday 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.
