KEY MESSAGES

Updated at 637 PM CDT Sun Jul 5 2026

- Moderate risk of heat-related impacts this week, with peak heat indices between 100-110 degF. Continue to practice heat safety.

- Low chances of daily isolated showers and thunderstorms over the Coastal Plains. Rain chances increase slightly by the end of the week and into the weekend.

DISCUSSION

Issued at 147 PM CDT Sun Jul 5 2026

Mid-level ridging will gradually build in from the west through the next couple of days as the ridge over the southeastern CONUS weakens. This pattern will continue to allow for predominately rain- free conditions. However, at the surface, persistent southeasterly flow will maintain a warm, humid airmass across the region. Diurnal heating combined with the daily afternoon seabreeze will serve as the primary focus for isolated shower and thunderstorm development over the next few days, particularly across the Coastal Plains. Overall, chances will remain on the low end (10-20%).

Looking toward the latter part of the week and into next weekend, an upper-level trough is forecast to traverse the ridge over the southeastern US, allowing a stalled frontal boundary to sag into north Texas. At the same time, increasing Gulf moisture associated with a tightening pressure gradient and a very weak disturbance/wave in the Bay of Campeche may support a modest increase in afternoon shower and thunderstorm chances across South Texas. Confidence in the timing and coverage of any rainfall, however, remains low at this time.

Temperatures throughout the forecast period will remain at seasonal normals. Afternoon highs will generally climb into the 90s, with the hottest locations across the western Brush Country approaching the upper 90s to near 100 degrees. Combined with persistent Gulf moisture, heat index values will range from 100-110 degrees, with a few locations briefly approaching Heat Advisory criteria. Please continue to practice heat safety by staying hydrated, taking frequent breaks in shaded or air-conditioned locations, and limiting strenuous activity during the hottest part of the day.

AVIATION

(00Z TAFS) Issued at 637 PM CDT Sun Jul 5 2026

VFR conditions are expected throughout this forecast with MVFR conditions possible at VCT, COT and ALI. Out of those three, ALI could drop to IFR for a few hours tomorrow morning due to localized fog. All sites will return to VFR by mid morning.

MARINE

Issued at 147 PM CDT Sun Jul 5 2026

Gentle to moderate south-southeasterly winds (BF 3-4) will persist into midweek before becoming primarily moderate to fresh (BF 4-5), particularly across the southern bays and southern offshore waters. Low daily rain chances will also continue through much of the week before increasing by late week and into next weekend in response to increased moisture push from a very weak disturbance/wave in the Bay of Campeche.
