AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
633 PM MST Mon Jan 13 2014

.UPDATE...Busy afternoon across the forecast area as strong west
winds and mild temperatures turned to north winds and snow across
North Central Montana. Have cancelled the High Wind Warning in the
north and expanded a Winter Weather Advisory across western
portions of North Central Montana. So far, no snow has been
reported in my northeast zones but will hold on to the advisory a
bit longer in that area to see if snow expands in that direction.
Winds are also coming down across Southwest Montana although the
Canadian cold front has so far not made it to Helena. Believe the
High Wind Warning in these areas could be dropped early as well,
but will hold on making changes in this region until the evening
model runs come in. mpj

&&

.AVIATION...
UPDATED 2350Z.
Widespread snow is overspreading much of North Central MT this
evening. Visibilities will be below 1/2SM in many areas with snow.
The snow will move into Southwest MT after 02z...but for now
Helena and Bozeman should not see the worst of these conditions.
Otherwise mountains will be obscured. Expect slowly improving
conditions from north to south after 08z tonight. Gusty winds are
expected on Tuesday afternoon in the Cut Bank area...with
gradually clearing skies in most areas during the afternoon hours.

.PREV DISCUSSION...
/ISSUED 452 PM MST Mon Jan 13 2014/

Tonight through Wednesday...Water vapor indicates a strong high
pressure ridge to the west with moist northwest flow aloft. A wave
shows in the flow north near the Canadian border. An associated cold
front is moving through the northern zones. A brief period of rain
will switch to snow as the cooler air mass moves into the area. Very
strong height rises are behind the front and the cold front should
continue to move quite fast. The upper level high pressure ridge to
the west will slowly move east tonight. This will help dry the air
mass and quickly drop the chance of precip by early Tuesday morning.
A short wave will move over the BC coast Tuesday night, move into
the ridge, and over the Rockies by Wednesday. The air mass will
remain relatively dry but this shortwave will help increase winds
again. Temperatures will cool Wednesday as the cold front drops
south of the border.  However, most of the cold air will remain well
to the east and north of the zones. The northeast will see the most
cooling but Southwest Montana will see little change. Zelzer

Wednesday Night through Monday...Medium range models are in good
agreement with the forecast solution for this period. This will be a
mostly quiet weather period with only minor fluctuations in above
normal temperatures from day to day. A weak disturbance in the
northwesterly flow aloft will exit the area Wednesday night, for
decreasing westerly downslope winds. Otherwise, an upper level ridge
of high pressure centered over the Pacific Coast will gradually move
onshore and into the northern Rockies from Thursday through
Saturday, keeping the area dry. A shortwave trough will then move
through the ridge and across Montana Saturday night through Sunday
night, bringing a brief increase in the westerly downslope winds to
the area, along with a chance of mainly mountain showers. The upper
level ridge will then rebuild over the Pacific Coast Sunday through
Monday, and the resulting moist northwesterly flow over the forecast
area will keep a slight chance of showers over the mountains.
