AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1055 PM MST Thu Feb 13 2014

UPDATE TO AVIATION

.DISCUSSION...
Very little change to the ongoing forecast this evening. Winds have
decreased and the high wind warning was allowed to expire earlier.
Radar returns have weakened over the Rocky Mountain Front but some
snow continues to fall and a few places along the front range are
still gusting to near 50 mph. Will therefore leave the winter
weather advisory in place until 5 am. Another upper trof approaches
the area Friday bringing another round of snow and gusty winds.
Models indicate southwest Montana should feel the brunt of this
feature and will continue the winter weather advisory for that area
beginning at noon. Additionally, winds should increase by late
morning along the Rocky Mountain Front and adjacent plains of North
Central Montana. Will issue a high wind watch from noon until
midnight to account for this event. Temperatures overnight look good.

&&

.AVIATION...
UPDATED 0555Z.
Unsettled west flow aloft will keep surface winds strong and gusting
overnight. The Northern Rockies will continue to be obscured
underneath snow and blowing snow. Elsewhere VFR conditions will
generally prevail although local MVFR conditions near showers are
expected. Winds will continue to diminish and conditions over the
Rockies will improve but IFR/MFR conditions will continue in or near
any showers. Winds will increase again during the daylight hours
tomorrow with some increase in shower activity again during peak
heating. Suk

&&

.PREV DISCUSSION...ISSUED 252 PM MST Thu Feb 13 2014

Tonight through Saturday...Windy conditions will continue over
portions of the region through the afternoon hours as an area of
surface low pressure moves off to our east. A mix of rain and snow
will continue into the evening hours over the Rocky Mountain Front
with the precip becoming more scattered by midnight. For
Friday...another upper level disturbance will move into the region
from the west...allowing for another round of precip/strong winds
to affect the region. There is the potential for high winds Friday
afternoon/evening over the Rocky Mountain Front and a high wind
highlight could be issued later today/tonight for that region.
Also...precip will become more widespread once again by mid day
Friday over the Rocky Mountain Front and across portions of
Southwest MT. Thus a winter weather advisory is in effect for
those regions until 5 AM Saturday. Temperatures will remain above
normal at lower elevations over the next few days. Brusda

Saturday night through Thursday...A moist and unsettled weather
pattern will persist over the Northern Rockies through most of the
forecast period with temperatures through the early half of next
week 5 to 10 degrees above seasonal averages. As another upper-
level trough of low pressure with ample Pacific moisture and
associated surface cold front move across the Treasure State
Saturday night and Sunday, accumulating mountain snowfall is
likely for elevations above 5000 feet with a mix of rain and snow
possible across lower elevations, mainly with the cold front.
Behind the frontal passage by midday Sunday, strong downslope
winds will develop over the Rocky Mountain Front and adjacent
plains. Will continue to monitor for possible high wind and winter
weather highlights.

Drier conditions are expected on Monday and Monday night, however
there is a slight chance for snow showers in Glacier National Park.
Long-range forecast models remain in agreement regarding the overall
moist and active pattern Tuesday through Thursday, however there are
differences in the track and timing of each disturbance as well as
precipitation type/coverage and the potential for colder
temperatures. Despite these differences have raised PoPs to likely
for the mountains and slight chance to chance in the plains/valleys
for each period with a trend towards lower temperatures beginning on
Wednesday. MLV
