From Brian Germ:
After several afternoons near or above 100 degrees, temperatures will be slightly cooler heading into the work week as the chance for showers increases. Expect another mild and quiet evening across Central Texas Sunday night, with lows only reaching the upper 70s by Monday morning. Skies will remain clear to mostly clear with dry conditions.
A trough of low pressure over Louisiana will continue to slowly push west towards Central Texas. Moisture and cloud cover will increase on Monday due to this movement. Expect a good chance for scattered showers and thunderstorms for Monday afternoon and evening around Central Texas, but especially east of I-35. Afternoon temperatures will be cooler from the moisture, with highs generally in the middle 90s. Storm chances will be around 40% to 50%.
Unsettled weather will continue with the chance for scattered showers and thunderstorms into Tuesday as well as Wednesday. The bulk of the activity is expected to impact along and east of the I-35 corridor, and especially across our southeastern counties. Not all areas will see showers, but some locations could receive over and inch of rainfall by the end of the work week.
Rainfall chances will decrease by Thursday and Friday but a few isolated showers may be possible. Highs for much of the work week will remain in the middle 90s, with a slow increase into the upper 90s by the weekend.
