Short term...(tonight through Wednesday night)
issued at 150 PM CST Tuesday Dec 1 2015

Rap analyzing a 1004mb low over central Minnesota with an occluded front
extending eastward across northern WI into northern lower Michigan.
Conveyor belt precipitation ahead of the front/around the low mainly
confined across Upper Michigan...wrapping around into northern Minnesota/eastern
Dakotas. Spotty snow showers were rotating into northeast
Iowa/southwest WI ahead of middle-level pv-advection/steepening lapse

Look for snow showers to continue tonight as the closed middle-level
low/pv-anomaly moves east across the area. Appears a dusting to
perhaps a 1/4 inch of snowfall will be seen with these snow showers
overnight. Was concerned about some patchy freezing drizzle...but
current infrared/forecast ice cloud should be sufficient enough to produce
all snow. Otherwise...plan on lows tonight mainly in the middle 20s.

Some lingering snow showers again Wednesday morning within the
cyclonic as the low pulls toward the Great Lakes region.
Again...very little accumulation expected with perhaps a 1/4 inch at
most. Otherwise...mostly cloudy skies will be seen with highs
topping off in the 30s.

For Wednesday night...the low continue to pull farther east into the
Great Lakes region as high pressure begins to build in from the
plains. As a result...look for a gradual west to east clearing trend
through the night with lows dipping into the upper teens to the
middle 20s.

Long term...(thursday through tuesday)
issued at 150 PM CST Tuesday Dec 1 2015

A quiet period setting up for the region through the long term with
high pressure the dominant weather feature. There will be a couple
troughs passing through the mean ridging Saturday night and again
Monday night...but looks like nothing more than some increase in
cloud cover. Otherwise...looking at temperatures running well above
normal through the period.


Aviation...(for the 06z tafs through 06z Wednesday night)
issued at 1133 PM CST Tuesday Dec 1 2015

MVFR to IFR conditions are expected at times at the taf sites
through the forecast period. Flurries will continue at the taf
sites through much of the overnight hours. IFR conditions are
expected at krst while MVFR conditions will mainly be the rule at
klse. Cloud bases look to rise to MVFR for a period around middle
morning on Wednesday then IFR and possibly LIFR stratus edges in
from the northwest. Looking upstream across central into northern bases range from 300 to 900 feet with light snow
and flurries reported at times. This area of IFR to LIFR looks to
move into the taf sites late Wednesday morning into Wednesday
afternoon. Its possible for this to dissipate a little before it
moves in so will have to monitor cloud trends closely.
Otherwise...VFR conditions will eventually return on Thursday
