KEY MESSAGES

Updated at 110 PM CDT Fri Jul 3 2026

- Seasonably hot temperatures continue through the holiday weekend.

- Continued dry and hot for next week.

SHORT TERM

(Tonight through Saturday night) Issued at 110 PM CDT Fri Jul 3 2026

A strong mid to upper level high has moved to the east coast. This is producing weak easterly flow over Texas. Surface high pressure over the Gulf is keeping southeasterly flow in the low levels and a warm, moist airmass in place. Isolated showers and thunderstorms have formed again over the Coastal Plains, and we expect they will continue through the afternoon, but most places will stay dry. For the rest of the short term period the pattern will remain about the same. We should see a repeat of the last few days with overnight/morning clouds giving way to mostly sunny afternoon. Temperatures will remain near normal. Independence Day will be typically hot with highs in the 90s and heat indices 100-105.

LONG TERM

(Sunday through next Friday) Issued at 110 PM CDT Fri Jul 3 2026

A weakness will develop in the upper ridge to start the new week, but models have continued to be dry. This feature is looking less well defined than in previous runs and is not generating any convection until Tuesday. Even then, PoPs are topped out at 20%. Mid-week the subtropical ridge will build back over the region returning dry weather everywhere. Temperatures will creep up a few degrees toward the end of the period. The eastern part of the Coastal Plains could see a few spots reach heat advisory level Wednesday through Friday.

AVIATION

(18Z TAFS) Issued at 1243 PM CDT Fri Jul 3 2026

Skies remain VFR at all TAF sites through the afternoon as some isolated convection continues over the coastal plains. Convection is expected to remain east of the I-35 terminals, but will monitor as outflow boundaries may temporarily disrupt the south to southeasterly winds. We do expect to see low clouds develop early Saturday morning. However, forecast soundings do show a fairly shallow moisture layer, which will result in a slightly shorter window of MVFR cigs. For DRT, we will leave the forecast VFR through the period, but did mention some SCT low clouds around sunrise into mid-morning.
