A Flash Flood Watch has been issued once again for the following counties in Illinois: Jo Daviess, Carroll, Whiteside, Stephenson, Winnebago, Ogle, Boone and McHenry. While most of Sunday afternoon was dry and warm, thunderstorms are increasing in coverage from the northwest. Storms over northeast Iowa and southwest Wisconsin were severe, producing damaging wind gusts, but locally our overall severe threat remains low. A few of the stronger storms could produce locally strong winds, but heavy rainfall remains the biggest concern.
