The Storm Prediction Center has just issued a discussion talking about the possibility of a Severe Thunderstorm Watch being needed later tonight for parts of Deep South Texas. At this time, they are not planning to issue a watch for Central or South Texas because the severe weather threat is expected to remain isolated. However, they say a watch may be needed further south in Deep South Texas and the Rio Grande Valley later tonight as instability increases.
A standard risk of severe weather remains in effect for Deep South Texas with lower probabilities to the north. For a complete explanation on the current severe weather risks, visit the blog post we made around 10 PM.

Severe Weather Risk for South Texas Overnight

The Storm Prediction Center maintains their standard slight risk of severe weather for much of Deep South Texas overnight tonight. This graphic shows the chance of severe weather occurring within 25 miles of any given location, such as your home, overnight tonight. The standard risk of severe weather is defined by the teal (bright blue) line, which denotes a 15 percent chance of severe weather occurring within 25 miles of your location overnight. That risk extends from the Mexico Border northward around Victoria. A lower risk of severe weather exists to the north of this zone into Central and East Texas, where a 5 percent chance of severe weather occurring within 25 miles of any given location is possible. At the time of this posting, no severe weather was ongoing. Flash Flood Watches remain in effect for much of South and East Texas overnight, and that is expected to be the primary hazard.
Tonight’s Severe Weather Hazards
- A few severe thunderstorms capable of producing quarter size hail and damaging winds in excess of 60 MPH. A brief tornado is possible along the coastline, but the threat is quite low.
- Heavy rainfall with some amounts exceeding two to three inches. Flash Flooding is possible in low lying areas and in urban areas. Please remember, Turn Around – Don’t Drown!

Several National Weather Services across the state have issued Flood Watches due to the potential for very heavy rainfall overnight and into the first part of Saturday. Currently, Flood Watches have been issued for areas like Austin, San Antonio, east to Houston, and northeastward into Northeast Texas. There are so many counties that they’re not really worth listing, however we have included more specific graphics below with city names. Please reference them for your specific location.
