central Iowa...northeast Iowa...southeast Iowa and northeast

.DAY ONE...TODAY AND TONIGHT

A Winter Weather Advisory is in effect tonight for areas along
the Highway 20 corridor in eastern Iowa and northern Illinois.
Snow is expected this evening into the overnight before tapering
off prior to daybreak on Wednesday, with 2 to 4 inches likely.
Locally higher amounts are possible near the Wisconsin border.
Snow covered and slippery roads are expected. There will likely
be a sharp cutoff on snow amounts to the south with less than an
inch of snow from Highway 30 to near Interstate 80.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

Another Arctic cold front will push through the area Wednesday
afternoon through Wednesday evening, bringing the potential for
strong, gusty snow showers. Any accumulations look to be under an
inch. These snow showers may impact travel with significant
reductions in visibility for short periods of time. Following the
snow showers, strong gusty winds to 40 mph may persist for several
hours Wednesday night leading to areas of drifting snow and
significant visibility reductions in blowing snow, particularly
north of Highway 30.

Bitter cold weather will set in from late Thursday through Saturday.
Temperatures will fall below zero, with dangerous wind chills
likely at times.

.SPOTTER INFORMATION STATEMENT...

Snowfall reports of an inch or more would be appreciated.
