...AREA OF CONCERN...Along and east of the I-35 corridor, including the areas hit hardest this past week with flooding rains.
...IMPACTS...Rainfall totals near 1 inch...isolated totals near 2 inches possible. This could lead to some urban flooding as well as minor flooding along rivers/creeks/low water crossings.
...TIMING...6 am Wednesday until Noon on Wednesday for the Hill Country and I-35 corridor. Areas farther east of I-35 will be a little later from 8 am Wednesday to 4pm Wednesday.
...DISCUSSION...A cold front will approach South Central Texas on Wednesday morning. Ahead of this system, light rain showers, and maybe an isolated thunderstorm, will develop over the area tonight and early Wednesday. Rainfall totals overnight will likely not amount to much more than 0.25 inches.
As the front approaches the Hill Country and the I-35 corridor by late morning on Wednesday, showers and thunderstorms are expected to develop, some of which will produce locally heavy rains. Even though we are expecting only 1-2 inches of rain, much of the area is saturated and the forecast of 1-2 inches could lead to minor street flooding and minor flooding along rivers/creeks/low water crossings. Most areas will receive totals that are much less than this. The NWS will be watching closely and if we see some areas where higher totals are occurring, will do our best to get that information out asap.
The front should push through the I-35 area by noon on Wednesday, shifting the heavy rain potential farther east as the entire system moves toward east Texas. The weather pattern will then become dry with pleasant temperatures and no chances of rain Thursday into Saturday.
