Threats & Impacts:

Threats and risk areas may continue to evolve as the event draws closer!

Rainfall:1 to 2 inches possible near and north of a Del Rio to San Antonio to La Grange line. Isolated pockets of 2 to 4 inches possible, mainly favoring far northern areas across Llano, Burnet, and Williamson counties. Localized flash flooding possible where heavier rainfall occurs.

Hail: Slight risk some storms could produce hail up to golfball sized

Winds: Slight risk some storms could produce wind gusts up to 60 mph

Tornadoes:  Isolated tornadoes can't be ruled out.


A strong upper level low and cold front will interact with increasing gulf moisture to produce showers and thunderstorms across South Central Texas. The storms are expected to develop along the Rio Grande this evening and move into portions of the western Hill Country overnight and Wednesday morning. Showers and storms will expand in coverage during the day and evening on Wednesday, possibly possibly forming into a line of storms that moves east.

There is a slight risk isolated to scattered storms could become severe, with hail and damaging straight-line wind gusts the primary threats. In addition, pockets of heavy rainfall are possible, producing localized flash flooding.

It should continue to be stressed that threats and locations of pockets of heavy rainfall may continue to evolve as the event draws closer.


Showers and Storms: Very High
