This Hazardous Weather Outlook is for portions of east central
Wisconsin, south central Wisconsin and southeast Wisconsin.



Wind chills in the teens below zero are expected into this morning.

A Winter Weather Advisory is in effect starting at 9 PM CST this
evening, mainly along and south of the Highway 18 and Interstate
94 corridor. This includes the Milwaukee and Madison metro areas.
Snow is expected into the overnight hours, with 2 to 5 inches of
accumulation expected. Locally higher amounts are possible,
mainly near the Illinois border area. Snow covered and slippery
roads are expected.



The Winter Weather Advisory is in effect until 6 AM CST Wednesday
morning, as the snow ends from west to east across the area.

Another Arctic cold front will push east through the area later
Wednesday into Wednesday evening, bringing the possibility of
locally heavy and fast moving snow showers. The best chances
would be southwest and south of Madison. These snow showers may
greatly reduce visibility quickly and cause hazardous driving
conditions.

Bitter cold temperatures and wind chills are likely Thursday
night into the weekend.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed, but snowfall reports will
be appreciated.
