.SHORT TERM...(This evening through Tuesday)
Issued at 334 PM CST Mon Jan 22 2018

Hazardous travel continues over portions of southeast Minnesota
through north central Wisconsin, but conditions will improve later
tonight.

Heavy snow will start to taper off late this afternoon over portions
of southeast Minnesota through north-central Wisconsin. Further
to the south mainly drizzle or perhaps a few flurries are expected
for much of the evening hours. The deformation band of snow is
then expected to edge back into southeast Minnesota and eventually
western Wisconsin late tonight. Additional snowfall of 1 to
perhaps 3 inches is possible through tonight mainly from Dodge
County northeast into norther sections of Wabasha, Trempealeau,
and Clark Counties. Further south any additional snow
accumulations will be less that 1 inch all the way through the
overnight. Ice will be lost aloft across much of the areas except
within the deformation band. We could see some light freezing
drizzle this evening before a switch over to very light snow. Any
ice accumulation will be light, around a glaze. The storms system
will exit the region early on Tuesday. Cooler temperatures build
back into the region on Tuesday with highs mainly in the 20s.

.LONG TERM...(Tuesday night through Monday)
Issued at 334 PM CST Mon Jan 22 2018

Weak high pressure builds into the region Tuesday night into
Wednesday. Plan on lows in the single digits to teens. Another
trough dives into the western CONUS on Thursday with warm southerly
flow setting up across the region for Friday. Friday will be an
seasonably warm day across the region with highs in the 40s,
possibly creeping into the 50s. A weak cold front sweeps through
the region Friday night bringing a chance of rain or possibly a
rain/snow mix to the region. Cooler northwest flow sets up across
the region late this weekend into early next week. A weak
shortwave moving through Sunday afternoon could bring some light
snow to the region.
