.DISCUSSION...

KEY MESSAGES:

- Bitterly cold temperatures continue through this weekend with
  wind chills dropping as low as 45 below zero in the far NE
  corner of the state. A Cold Weather Advisory and Extreme Cold
  Warning remain in effect.

- Temperatures warm to near normal early next week along with
  mostly dry conditions.

WEATHER PATTERN OVERVIEW:

An upper trough and arctic surface high pressure system is over
the region. The coldest temperatures will continue to be in the
northeast, with warmer temperatures in the southwest part of the
area. The subzero temperatures will end for most of the area after
Monday morning as the upper trough shifts further east. Until
then, periods of wind chills of 40 below or colder are nearly
certain for far northeast Montana through tomorrow morning.
Northwest winds and a weak disturbance over central Montana
Saturday into Saturday night will allow for scattered snow
showers, mostly when forced upslope. Petroleum, Garfield, and
southwest Phillips County have the best opportunity for snow. Up
to one inch of snow is the most likely scenario for these
locations.

Temperatures will slowly moderate through next week as an upper
ridge begins to affect the area, which will also limit chances for
precipitation.

FORECAST CONFIDENCE & DEVIATIONS:
Increased PoPs for today through early Sunday morning, especially
near central Montana. Increased winds for today as a cold front is
expected to move through.

There is high confidence of the placement of the Cold Weather
Advisories and Extreme Cold Warnings and a warmup on Monday.
There is moderate confidence for accumulating snow showers today
along areas close to central Montana. There is low confidence for
accumulating snow in the southeast part of the area. There is high
confidence in winds for today into tomorrow.
