Widespread showers and thunderstorms forecast from Midwest
Heavy rain is expected to expand across the Mississippi Valley, bringing widespread showers and thunderstorms from the Upper Midwest. An upper-level trough and a cold front will interact to produce these conditions on Tuesday. As a low-pressure system strengthens, the coverage of rain and storms is expected to increase overnight. The Mid-South region is particularly at risk for locally heavy rainfall as the system moves eastward towards Wednesday.
