Area of Concern:
All of South Central Texas, with the best chances of strong to severe storms on Sunday afternoon and evening before transitioning more to a locally heavy rainfall threat Sunday evening into Monday morning.
Threats & Impacts:
Tornadoes: A few tornadoes possible.
Winds: Wind gusts to 60 MPH.
Hail: Quarter sized or greater.
Rainfall: Average rainfall amounts of 1 to 2 inches with isolated amounts of 4 inches possible.
Timing and Overview:
A Pacific front and upper-level disturbance will move across northern Mexico into west Texas by Sunday afternoon and evening with temperatures and moisture levels ahead of the front more similar to mid-March than mid-January. Strong to severe thunderstorms are expected to develop by Sunday afternoon across the Edwards Plateau and Rio Grande Plains before moving east into the Hill Country and Interstate 35 corridor by Sunday evening. Soil moisture conditions are not expected to be conducive for flooding initially, but there is a potential for flooding by Sunday night into Monday as the front slows down and moves towards the Coastal Plains. Minor river flooding will be possible through the middle of next week as light to moderate rain showers continue into at least Tuesday.
Please stay tuned to updates on this evolving situation over the holiday weekend as changes in the forecast may shift the location and timing of the severe weather and locally heavy rainfall threat.
