MINNEAPOLIS (AP) -- Hearty Midwesterners know better than to put the snow shovels and snow blowers away in April.

Relentless wintry weather returns Monday with 6 to 9 inches of snow forecast for south central Minnesota and northwestern Wisconsin.

The National Weather Service has issued a winter storm warning through 1 a.m. Tuesday. Forecasters expected snowfall rates of 1 to 2 inches per hour.

In the heavier snow bands, visibility may be reduced to less than a quarter mile. Travel conditions are expected to rapidly deteriorate by Monday night.
