Area Forecast Discussion
National Weather Service Great Falls MT
1030 AM MST Thu Dec 15 2016

...AVIATION SECTION UPDATED...

.UPDATE...

Most of the forecast for the rest of today remains valid. A low-
to midlevel shortwave trough will continue to approach our CWA
from the Pac NW and southern BC. Thus, expect periods of primarily
light to moderate snow to persist the rest of today. Brief bursts
of heavy snow within narrow snow bands are expected in portions of
Central and Southwest MT per latest mesoscale model guidance.
These bands will stem from low- to midlevel frontogenesis amidst
abundant moisture. Over this portion of the CWA, a nearly-
stationary front separating arctic air to the north from milder
air to the south is expected to persist through at least sunset.
Through nightfall this evening, expect additional snowfall to
generally be 1-3 inches on the North-Central MT plains, 1-4 inches
in Southwest MT valleys, and 3-8 inches in the mountains,
especially those in Central and Southwest MT.

.DISCUSSION...

Thursday through Saturday...Latest upper air analysis shows a
positively tilted trough extending from the eastern Pacific NE into
SW Canada. Ahead of this trough, a strong 120kt+ jet is bringing
seasonally high moisture into the northern half of the western US.
Locally, widespread light snow has developed along/south of a line
from Missoula to Helena to Livingston. This snow appears to be
primarily driven by broad warm air advection (WAA)/isentropic lift
ahead of the upper level trough. The WAA/isentropic lift should
allow light snow to continue to move NE through the remainder of the
CWA through the morning hours, with snow continuing through Thursday
night, before tapering off from north to south on Friday.

The overall evolution of the system hasn't changed much, but there
are a few things worth noting. 00Z model guidance is now suggesting
a dry slot may cut across parts of central Montana Thursday
afternoon as the mid-level flow turns more westerly. This combined
with some potential downsloping effects, due to the westerly flow,
may limit snowfall coverage/intensity for part of the day Thursday
across central and western sections of central Montana. Whether this
pans out or not remains to be seen, but this may ultimately cut down
on snowfall amounts from Cut Bank to Great Falls and the latest
snowfall forecast reflects this potential. At the same time, the
low/mid level flow eventually turns more northerly by Thursday
evening which may allow for some upslope enhancement north of the
central mountains and may offset the drying aloft noted in the
models, at least near/south of the Great Falls area.
Therefore, for those areas, snowfall amounts were trended down some,
but not too much due to the uncertainties.

For the system as a whole, the models continue to point towards the
best lift located across the southern half of the state. It is in
this area that some mesoscale enhanced snowfall rates will be
possible, but may ultimately be determined as the event unfolds. So,
while a general 4-8" is expected at lower elevations of SW MT,
isolated higher amounts will certainly be possible if any mesoscale
banding develops. Of note, too, there may be a brief lull in the
heavier/steadier snow Thursday night across SW MT, but a second area
of enhanced lift may bring an additional round of steadier/heavier
snow on Friday. For now, left the current Winter Storm Warning in
this area as is, but later shifts may need to extend it further into
Friday. It is expected that the greatest likelihood of significant
impacts with this system will be across SW MT, with somewhat lesser
impacts as you go further north. That said, significant impacts are
still likely across parts of central Montana, especially southern
sections, but potentially not as widespread as further south. For
this reason, will keep the current Warnings/Advisories for central
Montana the same, but will closely monitor if any northward
adjustment in the advisory is needed for the remainder of the Hi-
Line.

In the wake of this system, the models continue to bring in
significantly colder temperatures by Friday/Friday night. The fresh
snowcover should help with lows bottoming out well below zero, but
the wind may prevent the coldest temps from being realized. Either
way, it is likely that much, if not all, of the area will at least
need a Wind Chill Advisory for Friday/Friday night.
Martin

Saturday night through Thursday...Medium range models continue to
show agreement for the weekend but their solutions diverge
significantly by early next week. Period starts off with an upper
level trough moving away from the state with downslope winds
developing east of the Continental Divide. The combination of
Chinook winds and increasing atmospheric thickness values will allow
temperatures to warm back towards seasonal averages for the early
portion of next week. Northwest to west flow aloft will continue to
bring accumulating snows to the mountains along the Continental
Divide while only isolated light snow showers move out over the
plains Sunday through Monday. Models also agree that an upper level
disturbance will across northern Montana Monday night but beyond
this time period significant differences arise mainly due to timing
and strength of shortwave activity in the flow aloft. At this time
it appears that high temperatures on Tuesday will be the warmest
seen in several weeks with gradual cooling expected each day beyond
that. Also, with west to northwest flow aloft over the region, have
kept PoPs in place over the western mountains with lower elevations
trending back toward climatological PoPs from mid-week onward.

.AVIATION...Updated 1730Z.

An upper level low pressure trof is moving over the West Coast and
moisture ahead of this system is moving through Nevada, Southern
Idaho, and into Southwest Montana. Periods of snow will continue
across Central and Southwest Montana through Friday with widespread
MVFR/IFR conditions and mountain obscuration.
