.DISCUSSION...

KEY MESSAGES:

- Brief warm up expected today across NE Montana with light snow
  at times mainly south of the Missouri River.

- After a cold night tonight and cold day on Wednesday,
  temperatures return to near normal on Thursday.

- Light snow is expected at times Friday and Saturday.

WEATHER PATTERN OVERVIEW:

A short-wave weather disturbance riding along the northwest flow
over our region will bring warmer temperatures across the region
today. The wave will also bring light snow at times today which
will be most frequent south of the Missouri River. Accumulations
will be an inch or less in most areas. A cold front this evening
will quickly shove those warmer temperatures south again, with the
snowfall ending early Wednesday morning.

Wednesday will be dry and cold before warmer air moves back into
the area on Thursday.

Friday/Saturday, another short-wave disturbance along the flow
will bring another round of snowfall to northeast Montana. Until
more detail can be worked out, a widespread 1 to 2 inches is
possible at this time.

FORECAST CONFIDENCE & DEVIATIONS:

Confidence is high for warmer temperatures today and colder
temperatures tonight and Wednesday. Confidence is low for
snowfall amounts today and again Friday and Saturday.
