Severe Storms Pack Large Hail, Tornado Threats | Weather.com

Severe storms will move across the Midwest, South, and mid-Atlantic today and tomorrow, potentially bringing strong thunderstorms, large hail, tornadoes, and high winds. Here’s a map of the timing.

Meteorologists say the storms are caused by a southward dip in the jet stream punching into the country's middle. That deep wind shear and moisture create the conditions for tornadic thunderstorms.

On the West Coast, Southern California was hit this weekend with an Easter storm that brought up to three inches of rain and as much as two feet of snow in the mountains. Winter storms have already drenched the area.
