Additional Heavy Rain in the Southwest into Sodden Texas, Spreading East This Week

An upper trough tapping into tropical moisture will continue producing locally heavy rain from the Southwest and Four Corners into Texas. Willa remnants deepen across Texas on Wednesday forming into a coastal low that is forecast to move slowly eastward into the Florida Panhandle later this week.

Severe storms developed late Tuesday afternoon along a boundary just south of the Interstate 90 corridor in southeast South Dakota. Large hail, dangerous lightning, and heavy rain accompanied these storms as they drifted southeast into northwest Iowa.

These storms developed in part to a very warm and unstable environment developing across the region, with dew point values again near the 70 degree mark. With little air above the ground to make the storms move, localized downburst winds were created, leading to very localized high winds. 

Rainfall was also plentiful where storms tracked.  Portions of the Sioux Falls area received upwards of an inch of rain in a short amount of time.
