...DISCUSSION...
An approaching upper level storm system and cold front combined with increasing moisture
from the Gulf of Mexico and the Eastern Pacific will lead to widespread rains across South
Central Texas starting late Tuesday afternoon into Wednesday morning. A cold front will
move into the Hill Country this afternoon and will help to trigger lighter rainfall during
the day. As an upper level disturbance moves closer to Texas tonight, widespread heavy
rains are expected to break out across much of South Central Texas during the evening and
overnight hours. The slow moving cold front will be an added trigger for rainfall, while
the deep moisture will help produce high rain rates. Rain totals late Tuesday afternoon
through early Wednesday could reach into the 2-4 inch range, with isolated totals near 7
inches. Flash Flooding is a concern and thus we have issued a Flash Flood Watch for all
of South Central Texas starting at 6 PM tonight until Noon on Wednesday.
Wednesday morning will see the front and associated heavy rain start to shift east and
south into the Coastal Plains of Texas, mainly along and south of a line from Carrizo
Springs to San Antonio to Hallettsville. Lingering rainfall is still possible across the
I-35 corridor on Wednesday but the threat for additional heavy rain will be pushing south
and east.
Please keep "weather aware" over the next 24 hours as forecasts and the timing
of the front/upper level system are fine tuned. Most flash flood fatalities occur at
night while driving. If you don't have to be out this evening through the overnight
hours, stay at home. Remember...Turn Around...Don't Drown.
