A few stronger storms are moving through Jo Daviess county near Scales Mound and Elizabeth.  These storms continue to move northeast with little movement eastward.  The storms have formed along a moisture axis in the upper levels of the atmosphere.  There is a little more storm development in eastern Iowa that will track northeast through far northwest Illinois this morning.

9:10 am: 1 SSW Galena, Jo Daviess Co., 0.25" hail - smaller than pea sized hail

8:55 am: Brooklyn, Green Co., 0.25" hail

8:30 am Update:  Storms continue to slowly drift to the northeast, slightly east this morning.  Watching a few radar returns that have seemed to light up within the past hour.  One storm moving through northern Green county, north of Monroe around New Glarus could produce hail, gusty winds and heavy rainfall.  Also watching a few storms in eastern Iowa that will move into Jo Daviess county that could produce pea to nickel sized hail.

Also watching one cell about to move into Monroe, Wi.  Hail, could be pea to nickel sized, gusty winds and heavy rainfall will be possible.  Look for this storm to be near Brodhead within the next 20 minutes.

6:00 am Update: Showers with a few embedded thunderstorms have developed this morning to the north and west of the Rockford Metro.  These have formed along the low level jet (stronger winds in the lower levels of the atmosphere).  The low level jet usually develops during the overnight and helps transport moisture.  The general motion of the showers is to the northeast and will likely continue to affect southwest/south-central Wisconsin and northwest Illinois for the next few hours.  While nothing severe is expected with these, brief heavy rainfall could be possible. 

The main cold front is still to the west in western Iowa and will be here later this afternoon.  This will again bring the storm threat to the Stateline with the potential for gusty winds and heavy rainfall.
