Aviation Section updated

.SYNOPSIS...
After a cold night tonight, warm air will begin to work its way
back into the area on Thursday. As it does, it will collide with
the existing cold air entrenched across the area, leading to
widespread accumulating snowfall during the day on Thursday. Most
locations will see between 2 and 5 inches of snow, with higher
amounts in the mountains.

&&

.UPDATE...
845 PM: No significant adjustments made to the forecast for this
update apart from some minor temperature changes. Based on
observations earlier this shift, noted that the Southwest region is
not warming up as quickly as originally forecast, but is still
expected to warm up throughout the day with the advancement of warm
air northeastward.

The abundance of highlights were left unchanged, but future shifts
may want to look into potentially upgrading the Rocky Mountain Front
as blizzard conditions are possible due to blowing snow Friday.
Though below high wind criteria, gusty winds of 40-60 mph are
expected and 4-10" of new snow expected west of Hwy 89, including
Hwy 2 up to Marias Pass.

Furthermore, it appears that the two floods with flood advisories
are forecast to remain in "action" stage per latest gauge readings.
No new news regarding the areal flood warning at Ennis Lions Club
Park in Madison.

530 PM: Adjusted tonight's low temperatures to account for the
current temperature at some locations within the Southwest region,
ie. Dillon, which never got above zero per observations. Used
NBM05 percentile as a baseline and then manually adjusted down
further to ensure tonight's lows were in fact lower than the
current observation. No other adjustments were made at this time.

.AVIATION...
1055 PM MST Wed Jan 5 2022 (06/06Z TAF period)

Main concern is the development of widespread moderate snowfall over
the region later tonight and on Thursday. Most terminals will have
LIFR/IFR conditions on Thursday for long periods of time. Snowfall
near moderate intensity is likely to last about 4 to 7 hours at some
terminals. Snow slowly starts to decrease in intensity from south to
to north starting around 18z Thu. Snowfall starts to become more
isolated towards the eastern portions of our region by 06z Fri.
Mountains/passes will be obscured through the period. Brusda

.HYDROLOGY...
Very cold air continues to reside over the region.A slow
moderation in temperatures is expected to begin on Thursday. Ice
jams continue to affect some rivers in Southwest MT.

Thus the current flood highlights listed below will continue
until further notice.

The flood advisory because of an ice jam continues until further
notice for the Gallatin River at Logan.

The flood advisory because of an ice jam continues until further
notice for the Jefferson River near Three Forks.

The flood warning because of an ice jam continues until 11 PM
Thursday for the Ennis area.

The return of the arctic air followed by more thaw and refreeze
cycles this weekend could result in the increase of ice jams. This
may cause minor flooding of farm fields and rural roadways.

.PREV DISCUSSION...
/ISSUED 425 PM MST Wed Jan 5 2022/

One final arctic night is in store across much of our area of
responsibility tonight as arctic air mass remains entrenched
across most of the area. The exception to this will be across the
Southwest, where warm air surging in from the southwest will have
already reached the surface.

The warm air will continue to advance to the northeast through the
day on Thursday, riding up and over the cold air at the surface .
As it does so, it will result in widespread snowfall across the
area, with a focus on the area north of Helena and White Sulphur
Springs and south of a line from Choteau to Landusky. In general,
expect 1-3 inches across the lower elevations, though 3-6 inches
is possible in the aforementioned band across the central part
of the area. Isolated higher amounts will certainly be possible,
especially if mesoscale banding is able to develop. In addition,
model soundings indicate that the Dendritic Growth Zone (DGZ) will
also be quite deep across the plains, which could help push snow
ratios higher than currently forecast (currently 15-20:1). All
that is to say that a few areas could still easily get some
"bonus" snowfall with this event.

Behind this system, winds will begin to quickly pick up as the
main piece of energy associated with tomorrow's snowfall passes
overhead. This is really where our attention will begin to shift,
as the gusty winds will readily blow around the freshly fallen
snowfall, especially along the Rocky Mountain Front. We've elected
to leave the Rocky Mountain Front in a Winter Storm Warning, but
significant blowing and drifting of the snow is looking quite
likely in this area as winds gust in excess of 45 mph on Friday.
Across the plains, we will be looking at a less severe version of
blowing and drifting snow, but the blowing and drifting snow will
still likely result in some areas of poor visibility and road
conditions. The biggest question across the plains will be how
much will the above freezing temperatures limit the blowing snow.
Right now it appears that the warmer temperatures should help, but
be alert if you will be traveling on Friday.

Behind this system, a brief cooldown will arrive as we receive a
glancing blow from an arctic air mass, bringing a brief cooldown
to the plains. However, as upper level ridging builds into the
area to start next week, temperatures will gradually climb into
the 40s, with limited chances for precipitation.
