AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
430 PM MST Fri Jan 24 2014

UPDATE TO AVIATION

.DISCUSSION...

Tonight through Sunday...Mainly dry and mild conditions will
continue through Saturday as a strong upper-level ridge of high
pressure remains settled over the Western U.S. Surface winds will
remain generally light through tonight, however on Saturday the
pressure gradient along the Rocky Mountain Front will tighten. Given
the tightening pressure gradient combined with an inversion just
above ridge-top level, there may be a period from Saturday morning
through Saturday evening where strong winds up to 60 mph may occur
through favored mountain passes and canyons along the Rocky Mountain
Front including eastern portions of Glacier National Park. A High
Wind Watch has been issued for these areas. These strong winds are
not expected to extend further east into the plains, however breezy
southwest winds of 20 to 30 mph are possible over the plains. The
overall weather pattern will begin to shift starting Saturday night
and Sunday as an upper-level shortwave and surface cold front move
into the area. The cold front will back into the area from
Saskatchewan and interact with Pacific moisture to produce light
snow over much of the area on Sunday. Snow accumulations will range
from 1 to 3 inches over the plains and 3 to 5 inches in the
mountains. As of now, the best lift will be over the mountains along
the Rocky Mountain Front and central MT ranges and with strong
dynamics on Sunday morning, there could be a brief period of heavier
snowfall. Temperatures will quickly fall from the low 30s into the
teens and 20s behind the cold front on Sunday. MLV

Sunday Night through Friday...Period begins with the area under a
relatively cold northerly flow aloft in the back side of a broad
mean upper low/trough centered over eastern Canada while a narrow
high amplitude ridge extends north along Pacific coast. Cold high
pressure slides south across MT at the surface Sunday night through
Monday and models have trended significantly colder with  temps Sun
NT/Mon. Mid level shortwave and upper level jet energy embedded
within the northerly flow aloft will move through central/SW MT
Sunday NT/Mon, producing scattered and generally light snow showers.
A brief period of drier and warmer conditions is likely Tuesday into
Wednesday before Pacific energy begins to undercut the high
amplitude ridge, bringing a return to unsettled and cooler
conditions late Wednesday through the remainder of next week. Models
have vastly different solutions in the position and timing of of
these features from Wednesday onward with the ECMWF model depicting
a cooler/wetter scenario as early as Wednesday while the GFS model
holds on to more ridging across the Western US through Wednesday and
Thursday before wetter/cooler conditions develop Friday into next
weekend. Confidence in either solution is low at this time but the
overall pattern change is likely and have trended temps and pops
close to climatological averages with hope for better agreement
through the next several days. Hoenisch

.AVIATION...
UPDATED 2330Z.
VFR conditions will continue for most areas through the next 24
hours. The relatively dry northwesterly flow aloft will keep the
area mostly clear with only a few passing high clouds. Winds will
remain breezy out of the southwest over the plains of north central
Montana, increasing after 14Z and becoming gusty. Gusts will likely
be in the 25 to 35 kt range over most of the plains, but gusts in
excess of 50 kt are possible along the Rocky Mountain Front. A
temperature inversion will likely develop again in the valleys of
southwest Montana between 06Z and 18Z, where patchy fog with
MVFR/IFR conditions may be possible at times. The most likely
terminal to have these conditions will again be KHLN, due to the
recent snowfall and resulting low level moisture there.
