AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
1045 AM MST Thu Jan 15 2015

.UPDATE...
Only adjustments this morning were to temperatures. Have warmed
temperatures about 4 to 8 degrees along the Rocky Mountain Front
and 2 to 4 degrees in the Dillon area, where breezy westerly
downslope winds have warmed temperatures to above forecasted
levels already in some places. Have also cooled temperatures 3 to
5 degrees in the Helena, Canyon Ferry, and Bozeman valley areas.
Cold air remains trapped there. Remainder of forecast is on track.
Coulston

&&

.AVIATION...
UPDATED 1745Z.
The main forecast problem during the period is the fog situation at
KHLN. Expect that MVFR visibilities will become VFR there this
afternoon. Then tonight confidence is low on what the visibilities
will be as they could range anywhere from VFR to IFR. Leaning
towards fog redeveloping after dark but then dissipating as clouds
aloft increase after midnight but again have low confidence with
this particular scenario. Elsewhere ceilings well above 15000 ft
will dissipate from the west this afternoon. Ceilings near and above
15000 ft will spread east near and after midnight but the only
threat for precipitation will be over the mountains of the Rocky
Mountain Front. Snow will become likely there Friday morning and
expect mountain obscurement. Wind gusts of 40 kts to 50 kts will
develop over the Rocky Mountain Front by midnight and continue
through Friday morning. Blank

.PREV DISCUSSION...
/ISSUED 435 AM MST Thu Jan 15 2015/

Today through Saturday Evening. The center of the high pressure
ridge that worked its way through WA/OR yesterday has now reached
western MT and is expected to make steady progress through the
state today. The passing ridge will bring mostly clear skies
across the central and southwest counties through this evening,
along with high temperatures in the upper 30s to mid 40s for most
of the region, though the Helena Valley and a few far southwest
valleys will remain in the upper 20s to around 30 degrees. Not
much change in model solutions for past several runs in their
depiction of shortwave trof closely following the ridge as it
exits into the Dakotas late tonight. Moisture associated with the
trof will bring some scattered areas of light snow, mostly to the
higher elevations of the Rocky Mtn Front and some of the southwest
mtn ranges. The most notable model change was a northward shift in
the path of the jet stream, now projected come across more of
central MT on Fri. With the resulting increase in coverage of 60
mph winds in the mid- and low-levels mainly north of a Helena-to-
Great Falls line, have expanded the earlier high wind watch to now
include the western Hiline and extending south to Cascade and
southern Lewis & Clark counties. Winds in the added area likely
will begin later than along the Rocky Mtn Front and last into mid-
Friday evening.

A surface cold front will push across our region Fri night as the
trof heads into eastern MT. The drying effects of the gusty
downslope winds will limit precipitation development through the
central counties, but can't rule out some isolated rain/snow
showers as the front sweeps south. Will also be monitoring
conditions for spotty areas of freezing rain, though current model
soundings generally indicate a low probability of occurrence.
Precipitation will dissipate quickly during the Fri overnight
hours and dry conditions are forecast for Sat. The cold front will
bring a temporary break in the warming trend as high temps on Sat
drop back into the mid- and upper 30s. Waranauskas

Saturday Night through Thursday...Progressive westerly flow aloft
coupled with embedded shortwaves and ample Pacific moisture will
keep unsettled weather over the Northern Rockies through the
weekend and early next week. Accumulating snow will be likely in
the mountains at and above pass level while windy conditions are
expected along and areas adjacent to the Rocky Mountain Front.
Forecast confidence is moderate to high regarding accumulating
mountain snow and gusty winds along the Rocky Mountain Front and
high wind and winter weather highlights may be needed. Snow
amounts Saturday night through Sunday Night will be 2 to 4 inches
at pass level with locally higher amounts above pass level. Snow
levels will be around 5000 feet so have kept a slight chance of
rain and snow across the plains/valleys. There is also the
potential for high winds greater than 58 mph along the Rocky
Mountain Front and adjacent plains Saturday night through Sunday
evening as a strong Pacific cold front moves across the region.
Will continue to monitor for possible high wind highlights. Highs
on Sunday will be well above seasonal averages.

Early next week, the overall flow aloft will shift northwesterly,
which will allow for cooler air to move into the area as well as
keep off and on chances for light snow. There is still uncertainty
regarding precipitation chances and snow amounts, but at this time
any snow accumulations should be light. Drier conditions are
expected by the middle of next week as a ridge of high pressure
begins to build over the Western U.S., though temperatures will
remain near to slightly below seasonal averages.
