The National Weather Service is warning of the possibility of strong to Severe Storms Are Possible Thursday for the Rio Grande, Hill Country and Portions of the I-35 Corridor... ...Locally Heavy Rainfall Possible on Friday for Most Areas...
Area of Concern:
Wednesday: Along and west of an Eagle Pass to Uvalde to Kerrville Line.
Thursday: Generally north of Highway 90 and west of I-35.
Friday: All of south central Texas, except south of a Pleasanton to Hallettsville line.
Threats & Impacts:Hail: Up to 1 inch in diameter.
Winds: Marginally severe winds up to 60 mph.
Rainfall: Event totals of 1 to 2 inches, with isolated amounts up to 4 inches. Higher amounts are anticipated west of I-35.
Tornadoes: Minimal, but not a zero threat.
Timing and Overview:
An upper level disturbance and cold front will combine to produce an active weather period over the next several days. On Wednesday, thunderstorms will initially develop mainly west of the Rio Grande during the afternoon hours, then move east during the evening. Thunderstorms will likely be severe as they move across the Rio Grande into portions of the Rio Grande plains and southern Edwards Plateau. Both hail and high winds are possible with these storms. On Thursday, another round of afternoon and evening storms are expected to develop across the Rio Grande plains into the Hill Country. As an upper level disturbance and cold front approach late Thursday night, we should see additional storm development farther east into the I-35 corridor. As the front slowly moves southward through the region on Friday, attention will then shift to the concern for locally heavy rainfall. At this time it appears locations west of I-35 will be most susceptible to localized flash flooding on Friday.
