Oppressive heat is in the forecast again for Tuesday as temperatures stay above average with high humidity. The dome of high pressure aloft has spread over Texas and will keep us dry Tuesday but as it retreats back to the west later this week, spot shower chances will return, as early as Wednesday ahead of a weak surface front which will stall to our north. It will be breezy again Tuesday but the onshore flow will weaken by mid-week and southeast winds will decrease to under 20 mph for the end of the week. Medium range forecast models are showing a possible tropical wave which could bring increased moisture and better rain chances around Labor Day but this far out, confidence is low.

Tropical Storm Dorian is approaching the Windward Islands and is expected to strengthen into a category 1 hurricane as it approaches Puerto Rico Wednesday then weaken slightly as it moves over the Bahamas. Dorian could affect the south Florida coast Labor Day weekend.

Monday night: Partly cloudy, warm and stuffy with lows in the lower 80s at the beaches to the upper 70s well inland with southeast winds at 10-18 mph.

Tuesday: Morning clouds then mostly sunny, hot and sticky with high temperatures near 90 at the beaches, upper 90s in Corpus Christi and 100-105 well inland. Heat indices will reach 106 at the beaches to 115 inland as southeast winds increase to 15-25 mph in the afternoon.

Wednesday: Partly cloudy, hot and humid with highs near 90 at the beaches, upper 90s in Corpus Christi and 100-104 inland with heat indices from 106 to 113 degrees. Southeast winds will reach near 20 mph in the afternoon. There is a spot shower or t-storm chance.
