AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
500 AM MST Wed Feb 19 2014

.DISCUSSION...
Today through Friday...Water vapor indicates another shortwave is
moving through the Pacific Northwest. The associated cold front will
cross the zones today and bring a cooler air mass into the region.
Most precipitation will be across the western Mountains and
Southwest Montana. Northern portions, mainly the plains, will be
underneath rather dry west flow and the chance for precip will
remain low. This west flow, however, will help keep snow and blowing
snow across the Northern Rockies at least through mid-morning, thus
the winter weather advisory for that area will be continued.
Likewise, with the continued snow over Southwest Montana, the
advisories will also be continued in that area. High pressure will
build aloft again Wednesday night. Another shortwave will be moving
into this ridge and approaching the Rockies Thursday. This will
increase the chance of precip again and keep brisk winds in the
forecast although not nearly as strong as today's winds. The jet
will remain south of the zones and keep the region underneath a cool
air mass. Flow aloft will remain cyclonic and unsettled with another
shortwave moving through the flow. The cold front associated with
this shortwave will bring another surge of colder air into central
Montana. This does not appear to be a particularly moist system.
Widespread snow is expected although accumulations will generally
remain on the low side. The Northern Rockies may need another high
wind warning Thursday but with the current high lights in place,
will try to avoid confusion and delay issuance. The cooling
beginning today will continue through Friday and temperatures will
drop to near or slightly below normals by Thursday and drop further
below normals Friday. Zelzer

Friday night through Wednesday...Models remain in agreement that a
very unsettled period will linger through the period as multiple
disturbances bring precipitation to various parts of Central
Montana. Timing and location of precipitation during this period
remains difficult to nail down; standard for a pattern of this
nature. Cold air and a chance for snow will come to Central Montana
from Canada on Friday. Temperatures will drop noticeably but do not
look to go more than 5 to 10 degrees below zero Sunday and Monday
nights. The disturbance largely moves out of the region late
Saturday with another wave bringing precipitation to Central and
Southwest Montana Monday. Things look to dry out over the plains of
Central Montana by Tuesday with only a weak shortwave possibly
affecting Southwest Montana into Wednesday. Overall temperatures
take a downward trend into Monday before things warm up Tuesday and
Wednesday. With a moist pattern expected, POP remains high over the
mountains during the long term forecast. Winds look to remain
generally breezy through the period, but not overly strong.

&&

.AVIATION...
UPDATED 1200Z.
VFR conditions prevail at most sites with MVFR conditions in the
vicinity of snow showers, mainly near KBZN and KHLN. Strong westerly
flow will continue. Mid and high clouds continue to increase through
the morning as a disturbance and associated cold front approach from
the west. Snow showers will develop, mainly over the mountains and
higher terrain. Clouds will begin to clear out by 00Z. Surface winds
will increase and become strong over the plains once again today.
Strongest winds will occur along the Rocky Mountain Front. Mountains
will be obscured at times.
