.KEY MESSAGES...
- Cold front brings cooler temperatures, breezy north winds and
scattered showers today.
- Cool temperatures continue through Tuesday (highs upper 40s to
mid 50s). Low temperatures tonight and Tuesday night in the
upper 20s to middle 30s.
- Light snow accumulations in the mountains through Tuesday. Rain/snow
mix possible (moderate chance) over the foothills and higher
hills tonight into Tuesday.

.DISCUSSION...
Through Sunday...
A cold front will drop through the region overnight into this
morning ushering in cooler conditions, brisk north winds and
scattered showers (25-60% chance) to the area today. High
temperatures will top out in the upper 40s to 50s, with northerly
wind gusts of 20 to 35 mph common post-frontal today. Showers
will decrease into this evening for most areas, before increasing
again heading into Tuesday, especially for the southern mountains
and foothills (40-75% chance) as embedded waves drop through the
area in cyclonic flow.
With cooler temperatures in place, snow may mix in with the
showers on Tuesday across the lower elevations, though any
accumulations look to remain limited to the mountains and
immediate foothills. Liquid precipitation amounts through Tuesday
look to range from a few hundredths over the plains, to a quarter
to as much as a half inch in favored northerly upslope areas in
the mountains. A general 1 to 5 inches of snow is expected in the
mountains, highest across the northerly upslope areas, with
locally higher totals possible. Light snow amounts are possible
into the immediate foothills, though the probability for exceeding
an inch is only near 30%. With low temperatures dropping into the
upper 20s and middle 30s tonight and Tuesday night, protect
sensitive vegetation. Confidence is highest with low temperatures
dropping below freezing (60-90%) Tuesday night/Wednesday morning.
Ridging is progged to build over the West Coast Wednesday and
Thursday placing our region under NW flow. Ensembles continue to
hint at a weak shortwave within that flow tracking over us
Thursday bringing a chance of showers and thunderstorms.
Probability of exceeding 0.10 inches of precipitation ranges from
30-60% for areas along and west of a Roundup to Billings to
Sheridan line, with areas to the east 15-30%. Ridging is brief on
Friday, as ensembles have continued with the trend of a PAC NW
trough developing and moving into the northern rockies Friday
night into Saturday. The strength and timing of this wave will
need monitoring, but has potential to bring increased
precipitation chances into the weekend. Temperatures look to range
from the 50s to lower 60s Wednesday, the 60s on Thursday, and the
60s to lower 70s Friday into the weekend. Overnight lows in the
upper 30s to 40s will be common most nights. STP
.AVIATION...
An approaching Canadian cold front will bring a shift to brisk
northerly winds across the region between 06-12z this morning.
Expect gusts of 20-30 knots. Breezy winds will continue through
the day. Behind the front will come increasing chances of mainly
light showers and areas of MVFR flight conditions today and
tonight. Mountains will become obscured in snow/rain showers. JKL
