Area Forecast Discussion
National Weather Service Twin Cities/Chanhassen MN
1158 AM CST Thu Dec 7 2017

.SHORT TERM...(Today and tonight)
Issued at 350 AM CST Thu Dec 7 2017

Clouds are on their way out this morning as the trough slides
southeast and ridging builds in. The clearing will last for the
day until clouds increase tonight ahead of the next system diving
south for Friday. Winds will finally be weaker today than the past
few days. This will make it feel milder, but the shallower mixing
and snow cover should keep temps from mixing into the mid 20s as
temps aloft would otherwise indicate.

WAA tonight and some moisture in the DGZ may generate a few
flurries. The abundance of dry air above and below this layer
will keep any accumulation from occurring.

.LONG TERM...(Friday through Wednesday)
Issued at 350 AM CST Thu Dec 7 2017

Low pressure will track from northwest MN to western or central WI
Friday afternoon, to Lake Michigan by Friday night. Areas along and
east of the track will see a period of snow, while to the west only
a few flurries will fall. An inch or two are forecast from this
quick mover, roughly east of I-35.

The pattern changes very little for the next 10 days. The deep trough
to the east and the anomalously large ridge to the west will maintain
a northwest flow for the Upper Midwest. Several clipper systems
will migrate southeastward, every one capable of some accumulating
snow in a relatively narrow corridor. These should occur Sunday
night/Monday, Tuesday/Tuesday night, and Wednesday/Wednesday

Temperatures will generally bounce in the near normal range
locally, with some variation up or down depending where each
system tracks.


.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1144 AM CST Thu Dec 7 2017

Midlevel clouds will continue to filter-in across MN and WI this
afternoon. Low-level clouds are anticipated to increase
overnight, bringing a chance for flurries this evening into early
Friday and a chance for MFVR ceilings Friday morning. Otherwise,
the best chances for snow and MVFR/IFR conditions return from
north to south after 18Z on Friday.

KMSP...VFR conditions will continue for today with a chance for
flurries this evening. Ceiling heights will decrease overnight, so
there is a slight chance for MVFR ceilings Friday morning.
However, the best chance for MVFR/IFR ceilings will be near and
after 21Z on Friday as snow chances increase.

Fri...MVFR with IFR/-SN possible after 21Z. Wind W-NW 10G15 kts.
Sat...VFR. Wind NW 10G15-20kts.
Sun...VFR. Wind SW 10G15 kts.
Mon...MFVR with IFR/-SN possible. Wind NW 10 kts.
