Scattered showers remain possible this evening across all of Central Texas. Showers may produce gusty winds, brief, heavy rain, and lightning.
Most of the convective activity should wane in the early evening hours. However, a northerly surge of sub-tropical air aloft is expected to move inland from the Gulf of Mexico, through the Brazos Valley late this afternoon and progress into the Waco/Temple/Killeen area this evening. As this occurs, it will help reignite showers and storms across the IH-35 corridor after midnight and through the early morning hours.
Scattered showers will continue Tuesday over most of Central Texas, with chances diminishing to cover just the IH-45 corridor on Wednesday. Thunderstorms may produce strong gusty winds, brief downpours, and frequent lightning.
Very hot conditions are expected by the weekend with temperatures reaching and exceeding 100 degrees. Afternoon heat indices will range from 105 to 112 degrees across Central Texas.
