.DISCUSSION...

Today through Saturday night...

High pressure over the region will maintain warm and dry
conditions today into Saturday. An upper low lifting out of
Colorado and into Nebraska may bring some light precipitation to
far southeastern areas Saturday afternoon into Saturday night.
Currently, there is a low chance (30% or less) for rain, with the
probability of 0.25 inches or more between 10-20%. Pressure
gradients also strengthen a bit over the western foothills
Saturday night, with some southwest wind gusts of 20-40 mph
possible at Livingston to Big Timber and Nye.

High temperatures in the 50s to around 60 degrees can be expected
today, with similar conditions for Saturday. Low temperatures in
the upper 20s to 30s are forecast for tonight and Saturday night.
STP

Sunday through Friday

While Sunday will be warmer and dry for most, a shortwave trough
passage will bring increased cloud cover and a low chance of
precipitation to the mountains during the day (15-30% chance,
highest over the Beartooth/Absaroka Mountains). Outside of this
activity, breezy conditions will persist over the western
foothills during the morning (wind gusts in the 20s and 30s mph).

On Monday, winds look to increase over the western foothills once
again ahead of a larger-scale trough. While this trough will
bring our next best chance of precipitation to the region Monday
evening through Tuesday, it will not be very dynamic and will not
contain a strong push of cold air. Because of this, the chance of
precipitation remains lower over the lower elevations (10-50%
chance, highest near the foothills and lowest near Baker, MT) and
all rain is forecast for the lower elevations. Given the time of
year, a rain/snow mix remains possible in the foothills. Outside
of precipitation, the breezy conditions along the western
foothills will push over the rest of the area Tuesday as the
trough axis moves over the area (gusts generally in the 20s to
lower 30s mph over the plains of southeastern Montana).

Ridging looks to build back in for Wednesday allowing warmer
temperatures and dry conditions to return. At this time, cluster
analysis shows decent agreement on another tough and the
subsequent return of precipitation chances to end the week, but
uncertainty remains at this time. Arends
