10:45am Update: A line of severe storms continue to move south of the immediate Stateline area this morning right along I-80.  However, there have been a few storms that have developed out ahead of this main line north of the warm front.  As of right now, the only severe thunderstorm warning is for southern Whiteside county, which is on the northern edge of the main bow echo, for damaging winds.  This storm is currently moving to the east around 50 mph and will likely move into Lee county within he next hour.  The storms that have formed out ahead of the main line are not posing too much of a severe weather threat as these are north of the warm front.  Heavy rainfall, gusty winds and possibly small hail will continue to remain a threat for these storms.

Severe Thunderstorm Warning for southern Whiteside county until 11:30am

9:40 am Update: Currently watchng a line of storms in southeast Iowa just southwest of the Quad Cities which appear to have bowed some.  These will likely continue to move east along and south of the warm front.  However, the northern extent of this line will push through with the continued threat of damaging winds.  Also watching storms that have formed out ahead of the main line moving to the northeast which could bring the severe weather threat here sooner.

A Severe Thunderstorm Watch has been issued for Carroll, Whiteside, Jo Daviess, Stephenson, Winnebago, Boone, Ogle, Lee, DeKalb and McHenry counties until 4pm.

First:  A Dense Fog Advisory continues for southern Wisconsin and northern Illinois through mid-morning Sunday.  Low level moisture combined with light winds has created some very dense fog in some locations.  Visibility will improve as the morning continues.

Second:  I'm watching storms that have developed out in Iowa early this morning.  A warm front lies to our south, right around Peoria, and lays from west to east.  These will continue to move east through the morning and could possibly become a bow echo as they move through northern Illinois with damaging winds.  A severe weather watch will likely be issued for northern Illinois soon.
