FORECAST

Congratulations Carrizo Springs (technically Faith Ranch): you were the hottest place in the country yesterday! That reporting site, which sits just SW of Carrizo Springs hit 111°. The big question is could we go even higher today?

HUMIDITY RETURNS

Humidity will slowly rise higher in the coming days. The more moisture content you have, the harder it is for the atmosphere to warm up and cool down. Plus, we’ll have more clouds. So, temperatures will subside. Unfortunately, humidity also makes it harder for US to cool down, so we’ll be talking about heat index values by Friday.

Added humidity this weekend will bring heat index values into play (Copyright 2025 by KSAT - All rights reserved.)

ANY RAIN?

As we see a bit more moisture and our heat high shift east, we open the door (barely) for some small rain chances. As of now, Friday night, Saturday, and Tuesday of next week hold the most promise for an isolated shower or storm.
