Severe Thunderstorm Watch Tuesday Evening

 Flash Flood Watch now in effect for Winnebago, Boone, Ogle, Lee, DeKalb and McHenry counties until 7am Wednesday morning.  The severe threat has ended, however, additional rounds of thunderstorms will continue through early Wednesday morning.  Most of the rain will be moderate, but pockets of heavier rainfall will be possible.  We'll begin to see the rain lighten up after 1am/2am Wednesday morning, but additional showers and embedded thunderstorms will continue through daybreak Wednesday.

We've received several reports of flooding across Rockford, especially in areas that typically experience flooding.  There have also been numerous reports of trees down and power lines down extending from near Roscoe down through New Milford, Byron and Davis Junction.









A Severe Thunderstorm Watch has been issued for Stephenson, Jo Daviess, Carroll and Whiteside counties until 11pm Tuesday evening.

Showers and embedded thunderstorms developed earlier Tuesday afternoon, moving northward from the Quad Cities.  There were some stronger thunderstorms over central and southern Lee County, but no severe weather reported.  The majority of the severe weather has been moving through central and eastern Wisconsin, with numerous severe thunderstorm warnings and tornado warnings.  Further southwest over Iowa, a line of thunderstorms have developed, prompted several severe thunderstorm warnings.  This line of storms is forming along and ahead of a

cold front that will move through southern Wisconsin and northern Illinois during the overnight.

Widely scattered showers and thunderstorms are likely between now and 7pm with little threat for severe weather.  The current rain activity has helped to stabilize the atmosphere over northern Illinois and this may work to weaken some of the storms back west of Iowa as they move across the Mississippi River.  If the line of storms in Iowa holds together, it would move into northwest Illinois between 7pm and 8:30pm, and then closer to Rockford by 8:30pm/9pm.  Strong winds still

look to be a primary threat initially as the line of storms move in, followed by heavy rainfall during the overnight.  Rainfall totals with some of the heavier storms will be between one and two inches.  A Flash Flood Watch remains in effect for Stephenson, Jo Daviess, Carroll and Whiteside counties.
