Over 25 million Americans are at risk for severe weather, including damaging winds, large hail, and tornadoes, with a significant threat shifting eastward across the central and eastern U.S. on Saturday. The storm system, part of an “omega block pattern,” will bring heavy rain and flash flooding, especially in the Northeast through Tuesday, with ongoing risks for central Texas on Monday. Previous reports indicate substantial hail damage and downed trees from Texas to Ohio, with a continued threat of flooding in saturated areas of the South.
