FORECAST

TODAY & TUESDAY

It’ll be quiet in San Antonio. Expect a high in the mid-90s, with a heat index near 100°.

TUESDAY NIGHT

A line of storms may develop across West Texas. This line is forecast to reach the Rio Grande late Tuesday night into very early Wednesday and bring rain to areas west of SA. This line likely dies down before reaching San Antonio.

WEDNESDAY NIGHT — ⚠ FLOODING POSSIBLE ⚠

By Wednesday evening, another line of storms will take shape along a slow-moving front and move east. This line will be capable of producing some strong storms, but the main threat will be heavy rainfall. As of now, this line of storms is forecast to reach San Antonio pre-dawn on Thursday.

THURSDAY — ⚠ FLOODING POSSIBLE ⚠

Storms are forecast to continue through Thursday. Should we see storms tracking over the same areas, flooding would be a concern. This is a timeframe we will watch closely.

FRIDAY AND BEYOND

Showers may linger into Friday and potentially the weekend. Clouds and rain chances will keep temperatures down.
