Weather Alert

Severe weather chance coming Tuesday, Hill Country flooding possible Wednesday

National Weather Service

BEXAR COUNTY (KTSA News) — There is a chance of some severe weather coming to the San Antonio Tuesday and a potential for flooding rainfall later in the week.

The National Weather Service said the primary threat is to the west of San Antonio, with the most significant potential for severe weather — a slight chance — covers an area from the Rio Grande into Kansas between Fort Worth and cities like Amarillo, Lubbock, and Midland.

In the Hill Country and Edwards Plateau, there are two rounds of precipitation Tuesday.  The first round, expected mid-day Tuesday, is predicted to bring moderate rainfall and strong storms to this region.  That night, strong to severe storms are possible.

These storms, particularly west of Eagle Pass, Uvalde, and Fredericksburg, have the potential of producing lime-sized hail.  Areas to the east, including San Antonio, could see quarter-sized hail from these same storms.  An isolated tornado is possible in the higher risk area of the state.  These storms are generally expected to bring about a half-inch of rain, though some areas could see a quick three inches of rain from localized heavy rainfall.

Wednesday night could see a second threat for significant weather, primarily more severely affecting areas north and northwest of San Antonio.

The National Weather Service said this second system is more of a rain event, which could lead to minor flooding.  The higher risk area — classified by forecasters as a “slight” risk, 10 to 20 percent probability of rapid onset flooding — primarily includes areas like Boerne, Blanco, Kerrville, Bandera, and Fredericksburg.
