KEY MESSAGES

Issued at 204 AM CDT Sat Aug 8 2026

- Moderate to major risk of heat-related impacts through the week, with peak heat indices 105 to 110, and high to extreme WBGT values.

- A low-medium chance (20-50%) of rain this weekend with highest totals along the coast.

DISCUSSION

Issued at 204 AM CDT Sat Aug 8 2026

Mid-level high pressure continues to dominate the weather pattern over the forecast period, with warm and mostly rain-free conditions expected. Seabreeze convection will be possible in the afternoons, with the best chances Saturday and Sunday as deep moisture (PWAT values ~2.1" along the coast) interacts with an area of vorticity riding around the periphery of the ridge.

Temperatures will remain hot, with highs in the 90s along the coast to around 105 over the Brush Country. With the increased moisture, though spotty in coverage, more cloud cover is expected this weekend, keeping the heat index generally below 110. However, isolated locations could see heat index values up to 112 due to lack of cloud coverage. By early next week, expect heat advisory conditions to return. Additionally, an extreme (4/4) heat risk is in play for the Brush Country starting midweek.

AVIATION

(06Z TAFS) Issued at 204 AM CDT Sat Aug 8 2026

A brief period of MVFR VIS/CIGs exist between 08Z-13Z at KALI/KVCT then becoming mostly VFR for all terminals through the end of the TAF cycle. KVCT was given PROB30 between 19Z-23Z for afternoon thunderstorms associated with the seabreeze.

MARINE

Issued at 204 AM CDT Sat Aug 8 2026

Light to moderate onshore breezes will persist through the weekend. Winds will increase to a more moderate to fresh breeze from Tuesday. There is a low to medium (20-50%) chance of showers and thunderstorms this weekend through early next week.

FIRE WEATHER

Issued at 204 AM CDT Sat Aug 8 2026

Min RHs will be in the 25-35% range each afternoon through the weekend in the western Brush country and Rio Grande Plains. These low RHs combined with ERCs in the 70-89th percentile range will lead to elevated fire weather conditions over this region each day. Winds will generally be around 15 mph, with wind gusts in the 20-25 mph range. A sea breeze shower cannot be ruled out this weekend though wetting rain chances will remain low.
