Area of Concern:
Tonight: Edwards Plateau, Rio Grande Plains, Western Hill Country.
Thursday: Along and West of I-35.
Threats & Impacts:
Winds: Gusts to 60 mph possible
Hail: Hail in excess of 1 inch possible
Tornadoes: Minimal threat
Rainfall: 0.5 to 1.0 inch
Timing and Overview:
An isolated severe storm or two will be possible near Val Verde County late this afternoon. This activity should mainly impact rural areas of Val Verde county. The greater concern will be late this evening into Wednesday morning as a line of strong to severe storms impacts areas mainly west of the I-35 corridor. The storms could produce strong to severe winds and hail over the Edwards Plateau, Rio Grande Plains, and western Hill Country. As this line of storms approaches the I-35 corridor early Wednesday morning, storm intensities are expected to gradually weaken.
Low impact shower and thunderstorm activity are expected along and east of I-35 on Wednesday, but strong to severe storms are possible over much of South Central Texas again on Thursday. Although the individual rounds of storms are not expected to create a major impact, a persistent chance of storms could lead to increasing concern for flooding this weekend.
Moderate Tonight; Low to Moderate Thursday.
