AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
402 AM MDT Fri Mar 13 2015

.DISCUSSION...
Today through Sunday...The big message is expect a change in the
weather by late in the weekend. For today an upper ridge will be
moving east through the forecast area. It will result in mostly
sunny skies. Southwest flow aloft will increase tonight as a weak
weather disturbance moves into western Montana. It will bring an
increase in clouds but no precipitation is expected. Southwest
flow aloft and embedded moisture will continue to increase into
Saturday night. Snow will develop over the mountains of the Rocky
Mountain Front by Saturday night but downslope effects should keep
the rest of the forecast area dry. Speaking of downslope effects
expect gusty southwest winds to develop Saturday. The NAM model
has increased winds aloft and the GFS continues to forecast strong
winds aloft over the Rocky Mountain Front. Consequently confidence
has grown enough to upgrade the high wind watch for that
particular area to a high wind warning. There is a small threat
for high winds maybe as far east as I-15 Saturday but confidence
is currently not high enough to issue a high wind highlight. A
cold front will move into the north Sunday afternoon and end the
threat of high winds for the Rocky Mountain Front. Models differ
on their precipitation patterns for Sunday but both agree that the
Rocky Mountain Front will see rain with snow in the mountains. Due
to model differences did not make any huge changes to the
inherited chance of precipitation forecasts but did increase the
chances of showers for lower elevations in the Rocky Mountain
Front. Some record or near record high temperatures are still on
track for today and Saturday and will even some over southwest
Montana on Sunday. Blank

Sunday night through Friday...Expect a rather unsettled weather
pattern to reside over the region to begin the work week. A Canadian
cold front will continue to move southward through the region Sunday
night into Monday morning. The cold front will generally stall out
along a Butte to Bozeman line by mid day Monday. Expect rain to
change snow behind the cold front as colder air moves into the
region. Current forecast models indicate a 1 to 3 inch snowfall over
the Plains of North Central MT...with 4 to 8 inches in the
mountains...mainly above 5000 feet...over the Rocky Mountain Front
and the mountains of Central MT. In Southwest MT...most of the snow
accumulations will be confined to the mountains above 5000 feet...as
the cold air will likely not go very far south of the I90 corridor.
A few models do have slightly higher snowfall totals...as they are
stronger with the cold air. We will continue to monitor this closely
over the weekend...but either way...the Monday morning commute over
Central MT will likely be the most impacted area. This cold air will
be short lived...as warmer air starts to move back into the region
on Tuesday. However...for Tue thru Thur...the flow aloft will
generally remain westerly...with weak upper level disturbances
moving through the region. Thus...there will be a chance for
scattered rain/snow showers from Tue thru Thu. Depending on the time
of day/elevation...snow will mix in from time to time. These showers
will be more scattered...but a heavier snow shower could produce an
inch or two in a small area...especially over the passes/mountains.
By next Friday...an upper level ridge is expected to rebuild over
the region...allowing for drier/warmer air to move back into the
region. Brusda
