FORECAST HIGHLIGHTS

  • COOL MORNING: Back down near 40° tomorrow morning
  • SMALL RAIN CHANCE: Sunday afternoon/evening, and later next week

FORECAST

Plan for another cool morning in the lower 40s tomorrow, but just like today, we’ll warm quickly and top out in the upper 70s by the afternoon with full sunshine. Also, the fire danger will be elevated again tomorrow and is considered “very high” according to the Texas A&M Forest Service.

SMALL RAIN CHANCE SUNDAY

Humidity will gradually increase over the weekend, and you’ll especially feel the mugginess in the air on Sunday, which coincides with a small chance of rain. A few storms could develop late Sunday into early Monday, but coverage would be limited. Otherwise, just plan for some morning fog both Saturday and Sunday, as well as afternoons in the mid 80s.

ANOTHER CHANCE OF RAIN

Although it’s still far away meteorologically speaking, there’s some hope for a pattern shift that could increase rain chances late next week. It hinges on a potential upper-level disturbance moving from Northern Mexico into Texas. Check back for updates!

ASTRONOMICAL SPRING BEGINS

The vernal equinox occurred at 4:01am. While the earth sits on a tilt, during the equinox, it’s neither tilted toward nor away from the sun. This produces equal amount of daylight and darkness at all latitudes. Bottom line... happy first day of Spring!

Spring began at 4:01am this morning. (Copyright 2025 by KSAT - All rights reserved.)
