We've been bracing for a big change in temperatures today, but the approaching cold front is also setting off a line of storms, and some have become severe. The National Weather Service has posted warnings for the following counties until 4 p.m. Monday:
Southern Milwaukee County
Southern Waukesha County
The storms could pack a punch, including winds reaching 60 m.p.h. and as large as quarter-size hail.
After the line moves through the state, temperatures are expected to plummet from the mid 70s to about 60, with lows tonight expected in the 40s.
