FORECAST

TODAY

After a brief round of morning clouds, we’ll see partly cloudy skies during the afternoon. It stays hot and we add humidity into the mix. Heat index values return to the forecast.

Meantime, a weak disturbance could stir up a storms in West Texas this afternoon. A few of these storms could make a run at places like Del Rio and Eagle Pass this evening. This activity should stay west of San Antonio.

WEEKEND

Morning cloud cover will last longer both Saturday and Sunday. Drizzle or a few sprinkles are possible Sunday morning. Otherwise, the afternoons will be warm and humid.

ACTIVE NEXT WEEK

The pattern becomes more active by Monday. Isolated storms are expected Monday evening. It’s impossible to know where a storm will pop up, but any storm that does will be capable of severe weather. By Tuesday, a weak front moving into North Texas will raise rain chances. Again, timing and placement of any storm is impossible to know at this point, but severe weather is a possibility. Beyond that, rain chances stay with us, potentially through Memorial Day weekend.
