The National Weather Service has issued a Severe Thunderstorm Watch for multiple Central Texas counties. The watch is effective until 4 a.m. May 22.

The watch includes the following counties: 

  • Hays
  • Travis
  • Williamson
  • Comal
  • Bastrop
  • Caldwell
  • Fayette
  • Lee

Strong and severe storms could form along a cold front as it moves through Central Texas, says FOX 7 Austin meteorologist Carlo Falco. Storms could produce strong winds to 60mph and up to ping pong ball size hail. The tornado threat is nearly zero and the flash flood threat is very low for today.

Behind the front much cooler weather is on the way. Temperatures will be about 20° cooler on Sunday and the humidity will be much lower. The humidity does increase once again Monday ahead of a series of low pressure systems that will be predominantly a rain/flood threat.

Storms should form through the afternoon and into the overnight hours Monday and into Tuesday morning. There’s a slight risk for flash flooding focused on the Hill Country west of I-35. Another round of storms is expected Tuesday night into Wednesday morning and the final round of rain Wednesday night into Thursday morning.

Rainfall totals should be in the range of 2-4" with localized areas receiving up to six inches of rain.
