Area Forecast Discussion
National Weather Service Great Falls MT
1051 AM MST Sun Dec 18 2022

.SYNOPSIS...
Very cold air will continue to move southward into Montana over
the next several days. Wednesday and Thursday will likely be the
coldest days this week. Additionally, periods of snow are expected
today into Monday, and again Tuesday night and Wednesday. This
cold snap will likely begin to break down on Friday, with
afternoon temperatures rising to near normal by Christmas Day.

&&

.UPDATE...

The morning update has been published. Temperatures were lowered
for southwest locations, mostly along and north of I90 by
blending GFS with the NBM guidance. For pops, the latest hi-res
guidance was incorporated to match current trends. The biggest
increase for pops was for tonight as a passing shortwave brings a
short period of accumulating snow to Central/North- central MT. -RCG

&&

.AVIATION...
400 AM MST Sun Dec 18 2022 (18/12Z TAF period)

Widespread light snow/low ceilings will affect all of North
Central MT through much of the forecast period. Snowfall will be
quite light over the Plains, but persistent. Low ceilings creating
IFR conditions will be the main impact. For the Bozeman/Ennis
areas, the low ceilings will be slow to move in, but it will occur
gradually today. Mountains/passes will generally be obscured
across the region/through the period. Brusda

Refer to weather.gov/zlc for more detailed regional aviation
weather and hazard information

&&

.PREV DISCUSSION...
/ISSUED 349 AM MST Sun Dec 18 2022/
Here is a break down of current highlights:

Winter Weather Advisory - Monida Pass - Until 11 AM Today:
Blowing snow will be the main impact, affecting travel on I-15
from south of Dillon to Monida Pass.

Winter Weather Advisory - Northern Rockies - Until Noon Monday:
Periods of steady light snow. Additional snow accumulations of 3
to 6 inches likely.

Wind Chill Advisory - All of North Central MT - Today thru Tuesday
night: Wind chills generally ranging from -20 to -40 below.
Frostbite can occur in less than 10 minutes with these wind chill
values.

Wind Chill Watch - All of North Central MT and the northern
portions of Southwest MT - Wednesday morning thru Thursday
morning: Wind chill values are forecast to be even colder during
this period - with values ranging from -45 to -60 below.
Frostbite can occur in less than 5 minutes with these wind chill
values.

Today through Tuesday...Periods of light snow will affect much of
North Central MT today, as a moist westerly flow aloft runs over
the colder air moving in at the surface. Since it will generally
be getting colder as well, our area will not be in the favorable
snow growth generation zone aloft, thus new snowfall amounts will
be low east of the Rockies. Over the Northern Rockies, more
moisture will allow for better snow accumulations, thus higher
snowfall amounts expected on Marias Pass. Further south, as of
3 AM, the main cold front is approaching the I-90 corridor from
Whitehall to Bozeman. The colder air will slowly continue to move
southward during the day. The snowfall does let up a bit Monday
afternoon into Tuesday.

Tuesday night into Wednesday...Another overrunning event is likely
to affect much of Central/Southwest MT during this time. More
moisture will be available, and a widespread snowfall of about 2
to 5 inches will be possible. A winter weather advisory for snow
might be needed for this event. Additionally, very cold
temperatures will continue

Wednesday night into Thursday...This will likely be the coldest
time period for this cold snap. Very strong surface high pressure
will reside over Central MT by Thursday morning. Most models prog
widespread overnight low temperatures of -30 to -40 below for
areas north of I-90. The probability of temperatures colder than
40 below is generally less than 30 percent. Wind chill values
will be even colder, likely in the warning criteria. Thus a wind
chill watch is now in effect for the northern portions of
Southwest MT and all of North Central MT. For areas that are not
in a wind chill warning, a wind chill advisory will likely be
needed.

Thursday night into Christmas Day...Another wind chill advisory
highlight will likely be needed prior to things warming up on
Friday. The very cold air will start to move east on Friday, as an
upper level ridge tries to build over the Pacific Northwest,
resulting in a northwesterly flow aloft Montana. Note, the cold
air will likely take an extra day or two to move out of the
Havre/Harlem areas. As the warmer air tries to move in, some
precipitation is possible. Some forecast soundings show warmer
air moving in aloft faster, so there is some potential that we
could have some freezing rain issues on Friday. The chances for
precipitation decrease over the weekend, as temperatures slowly
rebound closer to seasonal normals. Brusda
