General Discussion: The next cold front will be moving through North and West Texas today, Central Texas and Coast tonight, and South Texas tomorrow. Very warm and humid ahead of the front with 90 degree highs. Turning significantly cooler, windier, and less humid behind the front for the Wednesday-Thursday period – but not as extreme as the last front late this past week. Warming up yet again Friday into the weekend. Some 90 degree highs again possible over the weekend. Another cold front will affect Texas early next week. Precipitation over the next seven to ten days will be mostly associated with the fronts. Some areas will see a significant rainfall from this midweek front – highest chances in South Texas.
Today: The front will reach Dallas this evening, Austin, San Antonio, and Houston overnight tonight. Scattered showers today across Central sections of the state, stretching from west to east. The area of precipitation will increase in coverage and intensity tonight, after sunset, across portions of South, South Central, East, and Coast zones, with the area sinking south along with the front. Austin and especially San Antonio will have their best rain opportunity in months. Most or all of the precipitation will stay south of D/FW. Temperatures this afternoon ahead of the front will range from the upper 80s to middle 90s – along with fairly high humidity.
Tomorrow: Scattered showers and thunderstorms over South and Coast zones tomorrow morning, diminishing Coast and continuing South into the afternoon. Cooler and less humid behind this area of rain, over most of the state – as winds turn out of the North. 60s and 70s common for highs on Wednesday, after 80s and 90s on Tuesday.
