Thunderstorms Moving through for Some

9:35am Update:  Storms will continue to diminish through the morning hours, but we are watching one storm near Amboy.  Watch for heavy rain, frequent lightning and possibly hail as this storm continues to move very slowly to the northwest.

We'll continue to see sunshine as we go through the morning and into the afternoon.  Any boundaries that are left over from this morning could produce more storms through the afternoon. 

6:30am: Thunderstorms continue to move slowly to the west/northwest this morning thanks to a couple of outflow boundaries left over from storms last night.  The first boundary is moving in from the east from Lake Michigan (the storms we were seeing this morning), the second is a boundary moving through Iowa currently from storms left over in the Plains.  You can see by the radar image how quickly these storms "pop up" because of all the heat and humidity.  This will be the trend as we go through the morning and into the afternoon.  Since there is really nothing to push the storms through, heavy rainfall and frequent lightning will be the primary threat.
