FROM THE NATIONAL WEATHER SERVICE MONDAY MORNING:
…Multiple rounds of strong thunderstorms and heavy rainfall are expected late tonight through Wednesday…
Area of Concern:
All of South Central Texas
Threats & Impacts:
Rainfall: Widespread 1 to 3 inch amounts, with isolated totals up to 5 inches possible north of I-10. These rains will likely saturate soils and produce localized flooding in normally flood prone areas.
Additional Strong Storm Threats: Isolated stronger storms may produce up to 1 inch sized hail and wind gusts up to 60 mph.
Impacts: Several locations may experience minor flooding with flood waters capable of causing small streams, creeks, canals, and ditches to become swollen and overflow in a few places, but with little to no property damage. Quick ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Storm drains and retention ponds become near-full and begin to overflow in a few places. Flood waters may prompt brief road closures.
Timing and Overview:
An unstable pattern will favor repeated rounds of showers and thunderstorms, beginning as early as late this evening and continuing into Wednesday afternoon. Threats for strong storms and heavy rains should be mainly west of Highway 281 tonight before shifting east to along and east of the I-35 Corridor from midday Tuesday through Wednesday afternoon. A cold front is expected during the day Wednesday, but additional showers and thunderstorms are expected to continue behind the front for several hours.
