Mainly dry, hot weather continues Thursday with only a stray shower chance. You may want to get your lawn mowed by the weekend since rain chances increase as a tropical wave in the Gulf moves west and increases moisture in South Texas starting Friday. Widely scattered showers and t-storms are expected starting Friday, becoming more numerous Saturday with heavy rain possible in some of the storms. Temperatures will remain hot through the weekend except for areas that get downpours and rain cooled air. The tropical moisture moves out early next week and rain chances will become more isolated. The onshore flow increases this weekend and southeast winds will become breezy which will push heat indices as high as 109. Medium range forecast models are showing a possible cold front that could make it into south Texas late next week, giving us some relief with slightly cooler air and less humidity. There is still some uncertainty that it will make it this far south. We'll have updates in the coming days.
Wednesday Night: Partly cloudy, calm and mild with lows in the lower 70s inland to upper 70s at the beaches.
Thursday: Mostly sunny and hot with a stray shower chance. Highs will reach the upper 90s inland to near 90 at the beaches with southeast winds at 10-18 mph and heat indices up to 104.
Friday: Partly cloudy with spotty showers and t-storms at the coast in the morning, pushing inland in the afternoon. Highs will reach the upper 90s inland to near 90 at the beaches with southeast winds at 12-20 mph.
Weekend: Widely scattered showers and t-storms, some with heavy rain. Highs will reach the low to mid 90s inland and mid to upper 80s at the beaches with heat indices as high as 109.
