.DISCUSSION...

KEY MESSAGES:

 - Temperatures trend upward Sunday through Tuesday. Then moderate
   out mid-week.

 - Dry conditions through Tuesday. Chance of showers and isolated
   storms Tuesday evening into Wednesday evening. Dry rest of the
   week.

WEATHER PATTERN OVERVIEW:

A ridge over the western third of the CONUS will pass across the
area bringing a warming trend and then exit late Tuesday. A
smaller trough arrives from the Pacific Northwest Tuesday night
through Wednesday night. However, pacific moisture with this
passage appears to be lacking. Only leading to slight chance for
isolated showers with the passage. At the same time, a ridge will
rebuild into the Pacific Northwest behind it and begin having an
affect on northeast Montana Friday, warming conditions again.
This effect should last into Monday of next week.

FORECAST CONFIDENCE & DEVIATIONS:

Only real deviation was running NBM90 on winds to see if Lake Wind
Advisory criteria would be reached over the next couple days, and
even with NBM90, winds will stay just below criteria.

High confidence in above average temperatures tomorrow and
Tuesday, low confidence in precipitation timing, placement and
amounts.
