FORECAST

THIS WEEKEND’S RAIN

Last ight and today, a decent amount of rain fell for many. Check out the rainfall estimates:

MONDAY

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.
