Scattered Severe Storms, Heavy Rain Possible in Great Lakes, Midwest and Plains

June 26,2016
A few severe storms and heavy rain will impact parts of the Midwest and East into Monday ahead of a cold front pushing through those regions. Damaging wind gusts, hail and flash flooding will be the main threats.
Some localized heavy rainfall may impacts parts of flood-ravaged West Virginia on Monday, although extreme rainfall totals like we saw last week are not expected.
The National Weather Service (NWS) has issued a flash flood watch for central and southern West Virginia from 9 a.m. EDT to midnight on Monday.
Large amounts of rain are unexpected, but enough rain could fall to produce additional flash flooding across the areas that were impacted by the historic flooding last week. Additionally, remaining debris from that flooding could act as small dams with water pooling behind it.

The same front brought severe storms to the Upper Midwest on Saturday. Parts of Minnesota, Wisconsin and Upper Michigan saw reports of wind damage. In addition, an EF0 tornado touched down early Sunday morning near Green Bay, Wisconsin, damaging farm outbuildings and uprooting several trees.
Below is our latest forecast thinking on the timing and magnitude of the severe threats into Monday.
