DISCUSSION

Issued at 130 PM CDT Fri Sep 4 2026

The upper level disturbance has not moved much today and has kept convection northeast of the area. We're still expecting it to start drifting more southwest this afternoon though and will keep a 20-30% chance for showers storms in the Victoria Crossroads. Farther south did add some low (20%) pops along the seabreeze considering the convection that did develop yesterday. PWATs are a bit lower though, so it's not a certainty that we'll get any development this afternoon. As the mid-level energy and increased moisture move more over the region tomorrow and Sunday we should see an increase in convection activity. We're still only looking at 20-30% for most of the area with up to 50% in the Victoria Crossroads. Monday looks a bit quieter as this disturbance moves out of the region before another wave moves into the area on Tuesday into Wednesday increasing PoPs to 20-30 across the area.

High temperatures remain above normal overall through the period, but if/where showers/storms move through around peak heating time, some these locations could be a bit below normal for any given day. The additional sky cover and rain coverage should keep us just below Heat Advisory criteria through the weekend. However, the WBGT UIL risk will remain in the moderate risk level with heat indices 105- 110 and corresponding air temperatures from the mid 90s along the coast to 100-105 over the Brush Country.

AVIATION

(00Z TAFS) Issued at 644 PM CDT Fri Sep 4 2026

Scattered showers and an occasional thunderstorm is currently focused over Webb County, with the seabreeze pushing through westward. VCSH and TEMPO for rain has been added over the next couple of hours for LRD, but wouldn't be surprise if a rumble of thunder or two also accompanies. Rain chances diminish tonight, as well as winds overnight, becoming calm over the inland Coastal Plains. Surface moisture and calm winds will pose a fog threat from ALI to VCT, with winds aloft weaker over VCT, I do think the chances for denser fog is greater over VCT but not high enough to include in the forecast at this time. Additional showers and storms will develop tomorrow afternoon, mainly focused over the Victoria Crossroads, with spotty seabreeze convection over the Brush Country.

MARINE

Issued at 130 PM CDT Fri Sep 4 2026

Gentle to moderate south to southeast flow with 2-3 ft seas is expected through the period. We'll have low to medium rain chances daily into the middle of next week. Highest chances through the weekend will be north of Port Aransas.
