Please share. NWS - Tropical air mass will bring threat of heavy rainfall and isolated flooding/flash flooding threat through Friday. .AREA OF CONCERN...Areas mainly east of a line from Rocksprings to Pleasanton. This is roughly the eastern 2/3rds of South Central Texas. This includes the Hill Country, the I-35 Corridor from Austin to San Antonio, and the coastal plains east of I-35. IMPACTS...Locally heavy rainfall with rain rates that may exceed 2-3 inches per hour. Minor flooding, isolated flash flooding possible in those areas. Isolated rain totals of 3-5 inches. TIMING...Peak of the thunderstorm activity should be Wednesday afternoon and evening. While some decrease is expected overnight Wednesday, some activity will linger overnight. A repeat is possible again on Thursday afternoon and evening. Lesser chances on Friday. CONFIDENCE...Moderate to High. Look for the activity to peak during the late afternoon/early evening hours and then linger through the first part of the night, maybe even past midnight. So isolated flash flooding may be occurring later tonight. Remember that most of our Flash Flood Fatalities are related to driving at night. Thursday will see a repeat of the storm activity, mainly firing with daytime heating. Again we will carry the threat of isolated flooding/flash flooding with isolated totals of 3-5 inches possible. Rain chances will finally decrease by Friday into Saturday although isolated to scattered storms are still possible. We will need to watch this scenario closely. Whenever you are dealing with tropical moisture from left over tropical storms/hurricanes...it bears watching over South Central Texas.
