Heavy rain and flash flooding threat, north-central Texas
Flash flooding possible: Slow-moving thunderstorms are bringing heavy rainfall to north-central Texas south of Interstate 20, with flash flooding possible through 6:00 p.m. CDT. Recent hourly rainfall rates have reached 2-3 inches per hour in some areas.
Context
Light to moderate rain will continue through Saturday, most widespread across the southern half of the region, with rain chances of 40 to 60 percent lingering mostly across Deep East Texas into Louisiana.
What’s Driving It
Persistent slow-moving convection with repeated back-building cells is producing efficient rainfall in an environment with deep warm cloud layers and precipitable water near 2.4 inches. Rainfall totals near 6 inches have already accumulated since this morning between Corsicana and Fairfield. An additional 1-3 inches of rainfall is likely over the next few hours.
What To Look For
The slow-moving heavy rain is expected to continue for the next few hours before tapering off toward 6:00 p.m. CDT. Forecasters are monitoring the potential for flash flooding as these storms persist, particularly where training convection develops.
