...Rapid Change to Winter Weather This Morning...

A band of gusty snow showers along a strong cold front extended
back to southwest Wisconsin as 4:50 AM CST. These snow showers
can be expected to move steadily south across the area between 6
AM and 11 AM CST. Embedded bursts of heavier snow may tend to
focus east of I-39, which when paired with northerly winds
gusting to 35 to 40 mph, may reduce visibility below one mile at
times. A coating to around a half inch of snow may accumulate on
colder or untreated surfaces, with localized one inch amounts
possible in far northwest Indiana.

With temperatures starting above freezing and then quickly falling
into the 20s with the snow, slick spots may develop on some roads.
Motorists are advised to leave extra time to reach their destinations
this morning and be prepared to encounter localized hazardous travel.
Take it slow and keep a safe following distance when driving.
