.DISCUSSION...
KEY MESSAGES:
- Below normal temperatures through Saturday with the coldest places
  experiencing a freeze Saturday morning.
- Dry conditions continue as a warm-up brings a return to summer
  warmth by Sunday.
WEATHER PATTERN OVERVIEW:
Today will feature lighter winds and increased sunshine as cool
Canadian high pressure approaches. This will likely set up the
first freeze of the season tonight for some typically colder spots
near the Canadian and North Dakota borders with areas of frost
common there.
An upper ridge over the Pacific NW is expected to flatten while it
drifts into Montana by early next week. This will allow for mainly
clear skies and highs rebounding into the 80s Sunday and lasting
into midweek. Then, an upper low will push into the Pacific NW
that splits with a piece looking to break off into the Canadian
Prairies. This set-up gives at least a slight chance of
thunderstorms starting Tuesday night as some moisture and
instability from the Dakotas pushes back into the area.
FORECAST CONFIDENCE & DEVIATIONS:
Stayed close to the base forecast besides adding some detail to
short term winds and temperature spread. There is high confidence
in the forecast through Tuesday, then more average confidence
thereafter for the extent of rain chances.

elsewhere as afternoon gusts around 20 knots should be more
manageable than yesterday.
