.DISCUSSION...
Issued at 352 AM CST Thu Nov 21 2024

Lake effect stratus and light snow is occurring south of Lake
Sakakawea, with Hazen reporting light snow. This should only
last for a few hours before ending as winds become light and
variable. Otherwise, dry conditions with highs ranging from the
low 20s north to the upper 30s southwest are on tap today. Lows
tonight will be mostly in the teens. These high temperatures
are around 5 to 10 degrees below average for this time of year,
while the lows are near to slightly below average. Weak energy
tonight will provide a 20 percent chance of light snow in the
far northwest, though any accumulations are likely to be a
dusting at most. Dry conditions with similar highs are expected
during the day Friday as well.

During the period from now through Friday, a ridge starts in
place over the Highs Plains and will stretch eastward over the
Central Plains. Upper low pressure off the Pacific will split
into two individual circulations, which will do-si-do around
each other. The parent low will then begin to reingest the
second circulation, and momentum from this upper low dance will
result in a third low pressure center splitting off, spiraling
through the Rockies, and passing through south central
Canada/North Dakota as a clipper system.

Initially, as aforementioned ridging over the Central Plains
begins flattening Friday night, light snow off WAA is possible
mainly in the northwest and then expanding into the north
central Saturday. However, as the clipper begins to organize and
move through the area, snow chances increase Saturday night
through Sunday. At this time, there is now a 60 to 90 percent
chance of accumulating snow in the northern half of the state
Saturday night through Sunday. In addition, there is a 50 to 70
percent chance of 4 inches or more of snow mainly along and
north of Highway 2 and especially west of Highway 281. Winds
are not progged to be anywhere near as strong with this system
as the last system. However, breezy to windy conditions are
still in the forecast during the day Sunday.

Beyond Sunday night, multiple weak shortwaves are possible next
workweek, though the bigger story will be continued well below
average temperatures. Highs for next week are favored to be
mostly in the teens and 20s with lows mainly in the single
digits on either side of zero, though predominantly on the
positive side. That said, NBM 25th/75th ensemble forecast
spreads remain high for next week with plenty of room to be 5 to
even 10 degrees warmer or colder than in the present
deterministic forecast.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 536 AM CST Thu Nov 21 2024

Scattered low-level stratus is present over the north and south
central creating BKN/OVC ceilings at times, while overcast skies
are present in the east. Other than KDIK, which is expected to
remain VFR through the period, it`s difficult to pinpoint
exactly when/if MVFR/IFR ceilings will impact any particular
terminal and for how long this morning. That said, conditions
should improve through the morning, and once low-level status
clears, VFR ceilings and visibility are expected through the
remainder of the period.

.BIS WATCHES/WARNINGS/ADVISORIES...
