KEY MESSAGES

Updated at 127 PM CDT Sat Jul 4 2026

- Moderate risk of heat-related impacts into next week, with peak heat indices between 100-110 degF. Heat safety should continued to be practiced over the next several days.

- Low chances of daily isolated showers and thunderstorms over the Coastal Plains.

DISCUSSION

Issued at 127 PM CDT Sat Jul 4 2026

Mid-level ridging will gradually build in from the west through the holiday weekend as the ridge over the eastern CONUS erodes. This pattern will continue to allow for predominately rain-free conditions and very warm temperatures. Despite the drier environment, abundant low-level moisture and daytime heating will still support low chances (<15%) for isolated showers and a thunderstorm or two along the afternoon sea breeze across the Coastal Plains.

Temperatures will be near normal through the forecast period with high temperatures generally in the 90s and isolated triple digit temperatures across the western Brush Country. This combined with persistent Gulf moisture, will produce afternoon heat index values between 100-110 degF each day. While widespread Heat Advisory criteria are not anticipated at this time, portions of the region could briefly approach advisory thresholds during the hottest part of the afternoon. Those planning outdoor activities for the holiday weekend or spending extended periods outside next week should practice heat safety by staying well hydrated, taking frequent breaks in shaded or air conditioned areas, and limiting strenuous activity during peak heating hours.

AVIATION

(18Z TAFS) Issued at 127 PM CDT Sat Jul 4 2026

VFR conditions are expected to prevail through much of this TAF period. Brief reductions in VSBY are also a possibility across our two most popular trouble spots (ALI/VCT) around sunrise on Sunday. Isolated showers, perhaps a thunderstorm or two, will remain possible this afternoon and again on Sunday. The best chances for precipitation will remain across our easternmost terminals (ALI/CRP/VCT) where moisture is greatest, but overall chances are on the low side (<15%). Winds will continue to be out of the south- southeast at 10-15 knots through the rest of the afternoon and early evening, with occasional gusts up to 20 knots. Winds drop to 10 knots or less after sunset.

MARINE

Issued at 127 PM CDT Sat Jul 4 2026

Gentle to moderate south-southeasterly winds (BF 3-4) will persist into at least midweek. Low daily rain chances will also continue into early in the week.
