Area Forecast Discussion
National Weather Service Missoula MT
409 AM MST Tue Dec 3 2013

...BITTERLY COLD TEMPERATURES TO BEGIN TODAY...

.DISCUSSION...Snow and gusty east winds have persisted through the
night for most locations in western Montana, particularly the
Missoula/Bitterroot valleys, where snow accumulations and blowing
snow have become a major issue for the morning commute this
morning. Those traveling in these valleys should be prepared for
heavily degraded road conditions. Snow will taper off through the
morning, however travel may still be impacted by blowing snow,
causing low visibility.

This also goes for locations in northwest Montana who received
quite a bit of snow yesterday. Since east winds are howling just
about everywhere in western Montana, blowing snow will be common
through the day. Winds are expected to remain gusty today into
tonight.

Temperatures have steadily fallen through the night, and may not
noticeably warm today as more arctic air settles into western
Montana and central Idaho. This begins a long stretch of days with
bitterly cold temperatures and will have the added threat for
dangerous wind chill values. Time periods where wind chills will
be of greatest concern will be this morning, Wednesday morning,
and Thursday morning.

Wednesday and Thursday...ambient temperatures during the day will
be in the single digits, with overnight lows ranging well below
zero (especially for locations along the Continental Divide). In
addition, with gusty winds sticking around, wind chills will
values will feel even colder. Wind chills will regularly range in
the 0 degree to -15 degree range. The exception will be Thursday
morning, where wind chills could lower to almost -25 to -30
degrees along the Divide, with -10 to -20 across the remainder of
the Northern Rockies.

** If you must be outdoors for ANY length of time: make sure to
 cover exposed skin, as the threat for frostbite will be very
 high during this time. **

The extended forecast for this weekend into the middle of next
week can be summed up by one work: COLD The biggest question is
just how cold will we get and on which days questions which
largely depend upon cloud cover and wind speed (elements
classically hard to predict in numerical weather models). All
models agree that a second, reinforcing shot of arctic air will
move into the region on Friday and there will be some light snow
along the arctic boundary. However the bigger story will be the
dangerous, widespread sub-zero wind chill readings throughout the
day. Clearing is expected Friday night with temperatures again
plummeting Saturday morning, perhaps with readings even lower than
those achieved on Thursday. Only locations near canyons (like
Hellgate and Badrock) should see residual wind and the potential
for frostbite. Anyone with plans to be outdoors on Saturday should
be prepared for extremely cold and potentially dangerous
temperatures.

Northwesterly flow aloft will reintroduce better chances for snow
across the region starting on Sunday and continuing into at least
the middle of next week. Some models are still showing the potential
for a third shot of arctic air dropping into the Northern Rockies
early next week as well as a potential heavy snow scenario.
However all these come with very low degrees of confidence at this
time.

&&

.AVIATION...Low ceilings will combine with low visibilities due to
blowing snow to keep aviation impacts alive for KGPI and KMSO this
morning. KBTM and KSMN will also see their fair share of gusty east-
northeast winds, in addition to scattered snow showers. Overall,
snow will be ending through the day, but the primary impact will
then become the very gusty east-northeast winds, which could gust
up to 45 knots at times through the day.
