.DISCUSSION...

Through next Tuesday...

Above average temperatures and dry conditions will prevail through
Friday with zonal flow being dominant. Elevated fire weather
conditions are expected Friday with critical fire weather
conditions being possible. 500 mb troughing is expected to drop
into southern British Columbia Friday setting up a surface low
pressure system over southern Alberta/Saskatchewan. This setup is
expected to put much of Montana into the dry slot with downsloping
700 mb winds. High temperatures in the 80s F with minimum relative
humidity values in the teens are likely. Winds gusting into 20s
mph across much of the region with 30s and 40s mph for the western
foothills are expected.

A pattern change over the weekend will bring cooler and wetter
conditions through early next week. Ensemble systems are in good
agreement that upper level troughing will dive south along the
west coast. Deterministic models are showing a low pressure
system setting up over Montana and the southern Canadian
prairies. As the low pressure system moves off to the east, it
will bring a cold front across Montana Saturday. This cold front
will advect in Pacific moisture and cooler temperatures.
Temperatures Saturday are highly uncertain given the unknown
frontal timing. Locations near Judith gap could see high
temperatures in the 50s F on the low end while locations in far
Southeastern Montana and North Central Wyoming may still
experience much above average temperatures in the 80s F on the
high end. There is much higher confidence in widespread below
average temperatures Sunday with most locations seeing highs below
50 F.

There is even more uncertainty regarding precipitation and
precipitation type, though there are a few general statements
that can be made. Locations near the mountains and foothills will
receive more precipitation and have a better chance at seeing
snowfall and higher snowfall totals. Locations west of Rosebud
County have a 50-80% chance of getting greater than 0.5 inches of
precipitation with locations to the east having a 20-50% chance.
The chances for greater than 1 inch of snow over the lower
elevations from Yellowstone County and west are in the 40-70%
range. Precipitation chances increase Saturday behind the cold
front and begin to decrease throughout the day Monday. Stay tuned
to the forecast over the coming days as confidence increases and
the forecast becomes more clear. Torgerson


.AVIATION...

VFR conditions are expected over the next 24 hours. Winds along
the western foothills will begin to decrease this evening. Mostly
clear skies are expected to continue through Wednesday afternoon.
