Area Forecast Discussion
National Weather Service Grand Forks ND
342 AM CST Wed Dec 7 2016

.SHORT TERM...(Today and tonight)
Issued at 337 AM CST Wed Dec 7 2016

Sfc low and 500 mb low located just northeast of International
Falls at 09z. This low will continue to track slowly eastward.
Forecast will remain in the windy zone west of the low as mixing
up through 900 mb should continue where winds are 40-45 kt range.
Moisture is still wrapping around the low and mostly into the
northeastern half of the fcst area. Overall though lack of intense
snow in the high wind area is allowing for improving visibilities
to just above blizzard range in most areas and to match up with
WFO BIS will expire blizzard warning at 12z.
However enough wind today with gusts 40 or higher esp in the RRV
and DVL basin combined with areas of light snow wrapping back
around the sfc low to create low enough vsbys warranting a winter
wx advisory thru 00z thu. I did lower superblend and wpc qpf a bit
as with snow ratios in the 25:1 range think liquid content lower.
But still could see an inch or so of snow in the RRV but with wind
blowing will not be able to accuretly tell.

For the current non-blizzard warning area...Will also extend
winter wx advisory for far eastern fcst area where this area will
see a bit more actual snow falling with accums 2-3 inches nr
baudette-bemidji today into this evening.

Winds subside tonight though lingering areas of light snow will

.LONG TERM...(Thursday through Tuesday)
Issued at 337 AM CST Wed Dec 7 2016

Thursday-Friday...Upper level flow will transition to zonal by
the end of the week. Weak cyclonic flow remains on Thursday with
clouds and scattered snow showers remaining possible. Winds will
continue to be breezy, but much weaker and likely only minor
drifting issues will remain. On Friday, temperatures and cloud
cover will be the main challenges. There may be hope for brief
clearing, although confidence not high. Lowered temperatures for
Friday morning where the heavy snow is located into the teens
below zero (lighter winds and potential clearing). If clearing
does materialize, min temps could be even colder (which would also
affect Friday max temps.

Saturday-Sunday...Stronger system in zonal flow will bring a chance
for snow to the region. GEFS and operational models suggest
strongest forcing will track just south of the region. With that
said, at least accumulating snow likely across southeast ND and
central MN.

Monday-Tuesday...Colder temperatures and mostly dry, although light
snow might be possible.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)
Issued at 1135 PM CST Tue Dec 6 2016

Have kept the timing from the previous set of TAFs, keeping things
pretty stagnant from where they are now...through about 15z. At
that point will go with slightly higher vsbys. Models continue to
show another band of steadier snow dropping from north to south
across the area on Wednesday. This of course would affect the four
northern TAF sites by mid afternoon, and Fargo more toward 00z
Thursday. Not sure how low vsbys will get with this next bout of
snow, but did drop them fairly significantly.
