KEY MESSAGES

Issued at 1239 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

(18Z TAFS) Issued at 1239 PM CDT Tue Aug 4 2026

VFR conditions will prevail through the period with some periods of MVFR CIGs and VSBYs around daybreak through midmorning. Winds will remain elevated with gusts up to 30 knots through until this evening becoming relatively light. Though gusts around 25-30 knots will return by midmorning tomorrow across the region.

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.

FIRE WEATHER

Issued at 122 AM CDT Tue Aug 4 2026

Min RHs will generally drop into the 25-35% range each afternoon through the week over the western Brush country and Rio Grande Plains. These low RHs combined with ERCs in the 55-75th percentile range will support localized elevated fire weather conditions over this region each day. Winds will gradually increase out of the E-SE in the 12 to 18 kt during the afternoons. Daily rain chances will generally be 10% or less through the week.
