Heavy rain could lead to flooding in some locations
The National Weather Service on Sunday issued Severe Thunderstorm Watches for parts of Texas, Oklahoma, Illinois and Indiana as a spring storm system that brought severe weather to the Plains on Saturday continues to march eastward.
Severe thunderstorms are possible Sunday from an area that stretches from the Great Lakes region to the Texas/Mexico border with the primary threats being strong winds and hail, although an isolated tornado can’t be ruled out.
While areas in the system's warm sector see storms, other areas are being reminded that the book hasn't yet closed on winter.
Upwards of 2 feet of snow fell across the Northern Plains causing travel problems, especially along the I-90 corridor.
