An upper level low will interact with deep low level moisture and then bring a Pacific cold front through South-Central Texas Wednesday night and Thursday. This combination of features will lead to locally heavy rainfall over the Southern Edwards Plateau, Hill Country, and I-35 Corridor. Showers and thunderstorms will begin out west Wednesday night and move across the region Thursday exiting our eastern area Friday morning. Some storms will produce locally heavy rain leading to flash flooding. * WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...A portion of south central Texas, including the following counties, Bandera, Bexar, Blanco, Burnet, Comal, Edwards, Gillespie, Hays, Kendall, Kerr, Kinney, Llano, Medina, Real, Travis, Uvalde, Val Verde and Williamson. * WHEN...From late Wednesday night through late Thursday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded. * ADDITIONAL DETAILS... - Rainfall amounts of 1-3 inches with isolated totals to 6 inches. - http://www.weather.gov/safety/flood
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
