Area of Concern:
All of South-Central Texas
Threats & Impacts:
Winds: Damaging straight-line winds in excess of 60 MPH will be possible.
Hail:Large hail in excess of quarter size will be possible.
Tornadoes:An isolated tornado or two will be possible.
Rainfall: Up to 1". Localized higher amounts of 2-3" will be possible in stronger thunderstorms and may create minor/nuisance flooding issues.
Timing and Overview:
An upper level system moving across the state on Wednesday will bring a few rounds of showers and thunderstorms to South-Central Texas. Some of these thunderstorms could be strong to severe. The first round of thunderstorms will be possible Wednesday afternoon into the evening hours along a dry line, with environmental conditions during this time very favorable for very large hail and damaging wind gusts. A cold front is expected to overtake this activity sometime Wednesday evening or night, resulting in a line of thunderstorms moving across the region from northwest to southeast. The damaging wind threat is expected to become the primary hazard as this happens. An isolated tornado or two as well as locally heavy rain may also be possible during this time.
Thunderstorms will quickly shift southeast of the area Thursday morning with dry conditions expected through the upcoming weekend.
