A tropical wave in the south-central Gulf is expected to develop to a tropical depression in the next 2-3 days as it moves slowly west-southwest toward the northeast coast of Mexico. Most of the moisture is expected to move into southern Texas and Mexico where heavy rain is possible. Farther north in the Coastal Bend, scattered showers and t-storms are expected through Wednesday with rainfall amounts generally under a half inch, although higher totals are possible under slow moving storms, especially in areas south of Corpus Christi where tropical moisture will be more abundant. Temperatures will come down a couple degrees through Wednesday then rise as the dome of high pressure aloft moves back over us later this week, drying us out and heating us up through the weekend.
Monday night: Partly cloudy with lows in the mid to upper 70s inland and near 80 at the beaches with light east-northeast winds.
Tuesday: Partly sunny with widely scattered showers and t-storms. Highs will reach the mid to upper 90s inland and upper 80 at the beaches with heat indices up to 105 degrees. East-northeast winds will stay under 18 mph, except with wind gusts from t-storms.
Wednesday: Scattered showers and t-storms with highs in the low to mid 90s inland and mid to upper 80s at the beaches with winds from the east-northeast up to 18 mph. Heat indices will stay under 105.
