If you have Fiesta plans, don’t cancel! Take your jackets and grab the umbrella -- just in case.

MONDAY

Monday will be damp and chilly -- in the 50s (Copyright 2026 by KSAT - All rights reserved.)

An upper-level disturbance will bring another round of showers. While the rain won’t be heavy, off and on showers are possible throughout the day. This will keep temperatures chilly, with highs struggling to get out of the 50s. Showers may lessen a bit in time for the Texas Cavaliers River Parade, but this is not a guarantee. Plan for chilly & damp conditions if attending the parade. The good news? No dangerous weather is expected. In fact, even thunder and lightning will be kept at a minimum.

A few more light showers are possible Tuesday morning, but it’ll gradually warm in the week ahead. We’ll be monitoring a small storm chance for Battle of Flowers and Flambeau.
