.DISCUSSION...

KEY MESSAGES:

- Scattered light rain showers will move across the region today.

- Gusty west to northwest winds today and Wednesday will impact
  early season recreation out on Fort Peck Lake. A Lake Wind
  Advisory for Fort Peck Lake has been issued for today from 10 am
  to 9 pm Wednesday.

WEATHER PATTERN OVERVIEW:

The upper trough moving into the Pacific Northwest will slide east
today and flatten out. Shortwave and jet will push a low pressure
system away from the northern Rockies today.

A few showers may accompany the frontal system across eastern
Montana today. More importantly strong cyclonic jet, weak cold air
advection and downslope will lead to gusty winds today through
Wednesday evening. Winds may drop slightly overnight for a few
hours, but overall expected to be strong enough to extend the Lake
Wind Advisory out for another 24 hours (to 9pm Wed).

A secondary concern is fire weather conditions for today and
Wednesday with the gusty winds. Slightly cooler temperatures,
especially in the west, even with low relative humidity may create
elevated concerns for a time but not for widespread or prolonged
enough exposure to merit issuing headlines at this time.

Upper ridging will resume warm and dry conditions over the region
late week before the next rough arrives for the weekend.

FORECAST CONFIDENCE & DEVIATIONS:

Blended NBM90 into forecast with expected stronger conditions.
Confidence is high on gusty weather conditions for a time this
afternoon with more widespread gusty west winds on Wednesday.
Lower confidence exists on showers today.
