NAM4KM 8AM run suggesting two rounds of potentially severe thunderstorms for eastern MI

It looks like two distinct rounds of severe thunderstorms are possible this afternoon and overnight, specifically for the eastern U.P., north eastern lower Michigan, south eastern lower Michigan and especially the Thumb area.  Round 1 should begin at around 4PM and end around 9PM, and round 2 should begin around 11PM into the overnight, ending around 4AM.

The Thumb may once again bare the brunt of the storms if this model forecast is to be believed.  The 2PM NAM4KM run will shed more light on this situation.
