Wednesday washout kicks off stormy pattern; heat dome developing?

Draw a diagonal line from southwest to northeast across Minnesota and you'll find where there will be a washout on the right side of that line Wednesday. We're talking about 1-2 inches of rain for parts of southern Minnesota, including the Twin Cities.

We dry out a little bit Thursday before another shot at a storm or two Friday night, and then by Sunday our Memorial Day Weekend will be getting sticky with dew points in the 60s and maybe even 70. 

Those elevated dew points will serve as fuel for thunderstorms as Minnesota appears to be in line for an active, stormy pattern next week. The National Weather Service is already discussing possible severe weather Sunday into Monday for much of the Upper Midwest. 

And June could kick off with temps near 90 in the Twin Cities as a possible heat dome develops in the central and eastern U.S.
