.SHORT TERM...(This evening through Tuesday)
Issued at 315 PM CST Mon Jan 15 2018

The Winter Weather Advisory for Blowing/Drifting Snow was extended
thru 00z. Suspended snow continues to plague the central RRV
corridor with visibilities vacillating between 1/4 to 3/4 mile
from the Canadian border down through the F-M area. Some slight
weakening in the winds is starting to show, with a slow
improvement expected throughout the late afternoon.

Have extended the Wind Chill Warnings and Advisories into Tuesday
forenoon. Satellite imagery shows generally fair skies above the
blowing snows of the RRV and eastern ND... with patchy low clouds
expected to continue scattering out of west-central MN through
the late afternoon. Meanwhile... the 1050+ surface high pressure
up over the southern Manitoba lakes country will steadily
infiltrate the area overnight into early Tuesday morning. Temps
under this cold dome ran from -25 to -30F last night in Manitoba
and should have similar density qualities yet tonight as it hits
the central red River Valley. Thus we can expect lesser winds
overnight but much colder overnight temperatures...producing
similar wind chill effects tonight into early Tuesday.

Tuesday will see fair skies over the area and a light westerly
winds becoming light and variable. Temperatures will start our
quite cold, but recover most quickly on the higher elevation edges
of the Red River Basin in eastern ND and northwest MN (treed areas
most quickly), and linger below zero across much of the central
Red River Valley.

.LONG TERM...(Tuesday night through Monday)
Issued at 315 PM CST Mon Jan 15 2018

Weather impacts in the extended period continue to be minor with
relatively quiet weather. Tuesday night southerly winds will lead to
the beginning of a warm up that will last through Saturday. A
surface low will track to our north on Wednesday bringing with it a
chance for some light snow and gusty winds. In eastern North Dakota
the winds are expected to be higher with some gusts up to 30 mph.
The snow chances will be closer to the surface low near the Canadian

Temperatures Wednesday through Saturday will be warmer with highs in
the 20s and 30s. There is another chance for some light mixed
precipitation on Friday and while the GFS and ECMWF are consistent
on timing and placement QPF is different. Looking to ensembles, most
GEFS plumes keep the QPF on the low end despite a few plumes with
high totals. With the warmer temperatures on Friday p-type will be a
concern. BUFKIT GFS soundings show a variety of p-types with
temperatures near freezing at the surface. Looking forward, a
stronger system moves into the Upper Midwest early next week but
currently looks to stay to our southeast.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Updated at 315 PM CST Mon Jan 15 2018

Widespread IFR conditions will continue over the Red River Valley
proper through 23z...with strong winds producing significant
blowing and drifting snow. Most of the Red River Corridor should
have VFR CIGS after 00z... though patchy MVFR vsbys will linger
along the RRV corridor through 04z. West of the RRV in eastern
ND... expect mainly VFR conditions through the tonight and much of
Tuesday. East of the Red River corridor into northwest and west
central MN... expect mainly VFR conditions with patchy MVFR VSBYS
in blowing snow along the I-94 corridor through 04z.
