.DISCUSSION...

KEY MESSAGES:

- Mild temperatures are expected through the week.

- Light precipitation chances continue through Wednesday.

WEATHER PATTERN OVERVIEW:
The NBM has struggled with precipitation chances today because the
upper level trough pressure gradient that is over the region is
rather weak. Scattered rain and mixed precipitation showers are
moving through this afternoon and will continue off and on through
Wednesday afternoon. Low amounts of precipitation accumulation are
expected. There is a low probability of freezing rain occurring
with a shortwave trough on Tuesday night into Wednesday morning
with any precipitation that does fall.

FORECAST CONFIDENCE & DEVIATIONS:
Increased PoPs for Day 1 through Day 3 and increased winds with
NBM 90 for the local winds from Fort Peck to Vandalia. No other
changes were made.

There is low to moderate (20 to 40 percent) confidence of mixed
precipitation occurring through Wednesday afternoon. There is high
(80 percent) confidence of total precipitation accumulation
remaining below 0.05 inches through Thursday for all of northeast
Montana with this pattern. There is low confidence of freezing
rain occurring through Wednesday afternoon. There is high
confidence temperatures will stay near to slightly above average
through the entire forecast period.
