KEY MESSAGES

Issued at 614 PM CDT Tue Aug 4 2026

- Moderate-major risk of heat-related impacts through the week, with peak heat indices 106 to 112, and high to extreme WBGT values.

- Locally elevated fire weather conditions over the western Brush Country through the week.

DISCUSSION

Issued at 1239 PM CDT Tue Aug 4 2026

The forecast is staying on track from the last few issuances. Mid-level high pressure will continue to build over the next couple of days from the east and is still expected to take over by midweek. Expect this to promote warm and mostly rain free conditions outside of seabreeze convection. Will need to monitor the possibility for some short-fused heat related products. We could see heat indices up to 115 as early as tomorrow with dew points around the mid to upper 70s present through the next week. This translates to Moderate to Major heat stress conditions though we could see some areas reach Extreme conditions by Thursday. We strongly encourage the practice of heat safety in these conditions. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.

AVIATION

(00Z TAFS) Issued at 614 PM CDT Tue Aug 4 2026

Seasonal conditions expected through this period. Expect VFR conditions this evening, with some spots of MVFR conditions late tonight and early Wednesday morning, especially for ALI/VCT. A few showers are noted near COT this evening, but look to remain far enough east of the site to not warrant a mention in the TAF. Could see some isolated showers again tomorrow afternoon with the seabreeze, but coverage expectations are too small to be able to include in TAFs with any confidence at this time. VFR and breezy conditions return by mid-morning Wednesday and persist through the end of the period.

MARINE

Issued at 1239 PM CDT Tue Aug 4 2026

A generally gentle to moderate onshore (largely from the S-SE) flow can be expected through the forecast period, occasionally fresh winds can be observed along the nearshore bays in the afternoon. Seas will generally range from 2-3 feet through the period. Daily rain chances will be under 20% through at least Thursday.
