Area Forecast Discussion
National Weather Service Grand Forks ND
931 PM CST Mon Nov 20 2017

Issued at 931 PM CST Mon Nov 20 2017

No significant fcst updates expected this mid evening. Some light
snow is evident in observations north of the CanAm border, but
most visibility restrictions there have been the result of
blowing snow. A snow flurry is still possible overnight over the
LOW and Red Lakes region of northern MN.

Meanwhile...strong sustained winds and wind gusts persist across
the area,with highest sustained winds and gusts transitioning
from the Devils Lake Basin into the northern RRV. Pressure
gradient is relaxing a bit now as cold front has pushed well east
of the FA. The axis of highest pressure rises behind the front is
now moving across northwest MN and should be clear of the FA
around midnight. Moderate northwest winds will persist from the
late overnight into Tuesday.

UPDATE Issued at 602 PM CST Mon Nov 20 2017

Winds have steadily increased this past hour over eastern ND and
the RRV... with gusts to 45 mph in the Devils Lake Basin. Current
fcst package appears on target so no big updates planned there.
Updated Aviation Discussion issued below.


.SHORT TERM...(This evening through Tuesday)
Issued at 251 PM CST Mon Nov 20 2017

The main impact for tonight will be the strong north westerly
winds that will be advecting some much colder air into our region.
With the colder temps and the strong winds, we could see wind
chill values drop near to below zero by early tomorrow morning
north of highway 2. Tomorrow, winds will stay out of the north
west but will gradually die down through out the day. Temps
tomorrow will be much colder than what we saw today ranging from
the mid 20s in the south to high teens in the north.

.LONG TERM...(Tuesday night through Monday)
Issued at 251 PM CST Mon Nov 20 2017

Main concerns or weather impacts  for the holiday traveling period
will be Wednesday and possibly Friday. Both events appear to have
limited moisture to work with however both will feature the
potential for mixed precipitation occurrence. The first appears to
begin to impact the western areas Wednesday morning as scattered
snow across NE ND. During the afternoon warm air aloft moves in and
snow may mix with freezing rain as road surfaces and daytime
maximums stay below freezing, in the mid 20s. The chance for precip
ends Wednesday evening as the wave moves east and weakens.
Thanksgiving day is expected to be an excellent travel day with no
precip and light winds. Max temps in the mid 20s in NW MN warming to
near 40 in SE ND. Fridays chance for precip will be associated with
a jet max aloft as the next clipper system moves north of the FA an
northwest flow aloft begins. As a result a short window of mixed
precip will be possible friday morning before changing over to all
rain as 40s for highs are expected across the entire area. Breezy to
windy conditions Friday with westerly sfc winds. Cold front moves in
Friday night and temperatures will fall back into the 20s for highs
through the weekend.


.AVIATION...(For the 00Z TAFS through 00Z Tuesday evening)

overnight periods... with gusts to 45 mph across much of eastern

the evening and persist into midday on Wednesday.
