Heavy rain and flash flooding possible northeast Texas
Flash flooding threat: Slow-moving heavy showers and thunderstorms across north-central Texas this morning are producing rainfall rates over 2 inches per hour, with flash flooding possible through 1:01 p.m. CDT. The heaviest rain is developing south of Interstate 20, particularly between Corsicana and Fairfield.
Context
Light to moderate rain will continue through Saturday, most widespread across the southern half of the forecast area, with an upper-level trough shifting onshore before conditions taper off into early next week.
What’s Driving It
Slow-moving convection is persisting over the same areas due to deep warm layer cloud depths that make these storms efficient rainfall producers. With precipitable water near 2.5 inches, the environment supports substantial rainfall. The latest forecast models suggest this trend should continue through the late morning and into midday hours, with potential 3 to 6 inch rainfall totals possible between Dallas, Tyler, and Fairfield.
What To Look For
The heavy rain is expected to make its way toward the Dallas-Fort Worth area and the Interstate 20 corridor through midday. Forecasters are monitoring instances of flash flooding as the slow-moving storms continue, with the strongest thunderstorms south of I-20 capable of producing isolated street flooding.
