Waves of Rain Set to Sweep Central and Southern U.S. as Gulf Coast Eyes Saturday Severe Risk

Forecasters say the evolution of early-day convection will determine the severity along the Gulf Coast.

Overview

  • Bands of rain begin overnight Friday from the Plains and Midwest and expand south and east Saturday, with peak timing varying by region into early Sunday.
  • Forecasts call for 1–4 inches of rain in many spots with localized 5–6 inch pockets in Acadiana, prompting concern for street and flash flooding in vulnerable areas.
  • Southeast Texas and southern Louisiana face a Saturday risk for strong storms with heavy rain, gusty winds, hail and a low but nonzero tornado threat, and Houston sits under a level 2 of 4 flash-flood outlook.
  • Northern and interior areas remain chilly with active frost and freeze alerts, including lows in the 20s and 30s across parts of Wisconsin, New England, the Mid-Atlantic and the Ohio Valley.
  • A cooler, drier air mass settles in next week with more seasonable temperatures, providing some drought relief that is unlikely to fully erase longer-term deficits.
