Here's how much rain has fallen in and around Bexar County (Copyright 2026 by KSAT - All rights reserved.)
We have had an abundance of rain today, especially on the northeast side of San Antonio and near New Braunfels and Seguin. In some cases, 3-6″ of rain has fallen. This resulted in flooding in construction zones and near creeks.
TONIGHT
Rain will continue in waves overnight, mainly light.
TUESDAY
Lingering rain is likely, especially in the morning. If you are headed to NIOSA on Tuesday night, rain should be winding down. Highs on Tuesday will reach the upper-60s.
REST OF THE WEEK
Temperatures will return to more spring-like numbers. In fact, by Friday, we’ll be back near 90 for a high. While the pattern doesn’t show high odds for rain, we will see isolated storms each and every day. Should a storm develop Wednesday through the weekend, severe weather can’t be ruled out.
