- Seasonably hot with highs in the 90s and heat index values 101-108F each day. - An isolated late day shower can't be ruled out along the seabreeze, but most locations will remain dry. - Slightly better rain chances expected Thursday into the weekend with some deeper moisture moving in from the Gulf.

DISCUSSION

Issued at 1153 PM CDT Mon Aug 3 2026

Clear to partly cloudy skies and warm temperatures anticipated tonight with lows in mainly in the mid to upper 70s inland and the upper 70s to lower 80s along the coast. There is a chance for some isolated patchy fog early Tuesday morning, but chances are low. Fog, if any, will burn off quickly shortly after sunrise.

Weather conditions will remain hot and on the dry side through mid-week as the mid to upper level ridge remains situated over Arizona, New Mexico, and extends into Texas. Expect the highs to peak in the upper 90s inland (some isolated spots reaching 100 deg F) and the lower to mid 90s along the coast through Wednesday. Heat indices will peak between 103-108 deg F...thus, make sure to continue to protect yourself, your loved ones, and pets from the heat. From Thursday into the upcoming weekend, the highs are expected to range in the lower to mid 90s inland (although some spots could peak in the upper 90s) and the upper 80s to lower 90s along the coast.

Subsidence will help limit rain chances early in the week. Slightly better chances for showers (20-40%) are expected mid week into the upcoming weekend as surface moisture moves in from the Gulf waters and increases PWs. A good portion of these showers are expected to develop near/along the seabreeze during the afternoon to early evening hours.

VFR conditions are expected to continue with winds 5-10kts out of the S-SE. Tomorrow morning winds relax to 2-4 kts between 10-15Z for most of our terminals. At this point, patchy fog is possible but would burn up shortly after sunrise. Winds strengthen tomorrow afternoon to 6-10 kts from the S-SE, with stronger winds along our coast. An isolated SHRA is possible in the late afternoon on Tuesday with the primary concern around the I-10 corridor. Any storms that do pop up could be capable of producing gusts up to 15-20kts.
