Monday Weather Update

A line of convection has developed southeast of Rochelle early this afternoon and will lift northeast into DeKalb county.  This line is currently crossing over I-88 and will be near Creston, Malta, DeKalb, Sycamore and Genoa shortly.  Right now I'm not detecting any lightning strikes with this but there could be a few that develop shortly.  Watch for some heavy rainfall.

12:15pm Update:  The tail end of the showers/storms are lifting northeast out of DeKalb and McHenry counties.  The line of storms that moved through formed in an area that had a little more sunshine early this morning.  That combined with strong winds a few thousand feet above helped produce the storms.  While we didn't experience much across the Stateline in terms of gusty winds, heavy rainfall and small hail were reported. 

Going forward into the afternoon we'll likely get a couple breaks in the cloud cover but the greatest threat for severe weather will remain just to our east, basically east of I-39.  As the main upper low spins through this afternoon the possibility will remain for a few isolated storms.



A Severe Thunderstorm Warning continues for Milwaukee and Racine counties in southeastern Wisconsin until 12:15pm.

A line of storms has formed late this morning ahead of the main upper level low.  This has been in an area that has seen a little more sunshine through the morning.  The line extends from southeast Wisconsin back southwest through Marengo and Woodstock further south to Rochelle.  Currently there are no watches or warnings, however, there has been a little rotation noted within the line moving across McHenry county.
