Hail, twisters blast Iowa on way to Chicagoland

A potent weather system that will be moving through the Chicago area Monday blasted
areas to the west with numerous tornadoes and large hail late Sunday.
Several twisters swarmed northeast Iowa, north and east of Waterloo, damaging homes in
the area. At least one person was killed when a twister leveled at least 50 homes in Hugo,
Minn., just northeast of Minneapolis. Hail as large as baseballs accompanied the tornadic
storms.
The storm system, feeding on warm, humid air sweeping north into the Mississippi Valley,
produced nearly 400 severe weather reports through 9:15 p.m. Sunday, including at least
35 twisters.
SEVERE T-STORM THREAT MONDAY
Tornado watches were posted for northwest Illinois Sunday evening, and the remnants of
these storms will pass through northeast Illinois early this morning. More storms should
develop in today's warmth and humidity and could become severe, especially south and
east of the city.
