Area Forecast Discussion
National Weather Service Duluth MN
312 PM CST Tue Jan 24 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 312 PM CST Tue Jan 24 2017

A chance for snow late tonight into Wednesday with a gradual trend
towards cooler temperatures.

Overall little change in the forecast as a deepening low approaches
southern Wisconsin late tonight into Wednesday morning. Guidance
continues to trend just slightly further south with the track of the
low, and with a sharp northern gradient expected, this has resulted
in less snow forecast for northwest Wisconsin. As the low deepens,
northerly flow will develop at low to mid levels resulting colder
air being advected in from the north. While snowfall over northwest
Wisconsin will be little - 1 to 2 inches mainly along and south of
US-8 - some flurries/snow showers are possible Wednesday afternoon
as the colder air moves in aloft and low-level moisture remains
across much of the region.

Lows tonight in the mid to upper 20s - while there will be little in
the way of radiational cooling, some cooler air will advect in as
winds turn northerly. Highs Wednesday in the upper 20s to low 30s
with northerly winds increasing to 10-15 mph with gusts approaching
25 mph possible.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 312 PM CST Tue Jan 24 2017

The low pressure center will move northeast into eastern Michigan by
Thursday morning.  Colder air will flow into the forecast region
behind the low through the weekend.  However, the temperatures will
be about 5-7 degrees above normal into the weekend.  Weak shortwaves
will move through northern MN Thursday and Thursday night with
less than an inch expected.  The winds will turn N-NE Wednesday night
and Thursday which will cause lake effect snow showers to develop
with 1-3 inches expected before the winds switch around to the NW.
There will be scattered snow showers across the snowbelt Thursday
night into Saturday morning.  On Saturday, winds will switch back to
the N-NE as shortwaves move through the flow.  Heavier snow showers
will develop early Saturday and continue Sunday afternoon.

The rest of the forecast region will see widely scattered snow showers
flurries through the end of the work week with the weekend mostly
dry.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1132 AM CST Tue Jan 24 2017

Mainly mvfr cigs through the forecast period as the cyclonic flow
continues across the forecast area. There could be some IFR cigs
 possible at all TAF sites. The best chance for these conditions
will be at HYR as a storm system moves south of the area but will
spread snow into HYR late tonight and continue into Wednesday.
