.DISCUSSION...
KEY MESSAGES:
-  Widespread showers this afternoon into Monday for most of the
   Northern Rockies, for some a beneficial rain
- Warming and drying by mid week
An upper level trough along the West Coast this morning will
usher in a cold front by this afternoon. Showers and isolated
thunderstorms will increase from west to east across the Northern
Rockies. Wind gusts of 20-30 mph will be common mid afternoon
through early evening accompanying the front and showers. Areas of
showers will continue tonight through much of Monday as a weak
mid level low rotates through.
The probability of a wetting rain is high 70-100% for much of the
Northern Rockies, excluding far northwest Montana where chances
are only 20-40%. In fact, the probability for at least 0.25 inch
of rainfall is 40-70% across north-central Idaho and west-central
Montana. Overall, widespread showers are anticipated with a
beneficial rain for many locations. Additionally, it will be much
cooler with daytime highs 5-10 degrees below normal on Monday as
snow levels drop to around 8500 feet.
The Northern Rockies become stuck between deep troughs during the
middle of this week and temperatures blossom 5 to 10 degrees
above normal, with drying conditions, and light breezes. Ensemble
clusters diverge greatly around the 18th and 19th on the details
but generally agree on a weak upper level trough along the West
Coast. This trough should help to bring showers back into the
forecast with a gradual cooling in temperatures.

accompanying the front and showers. Areas of showers, periodic
lowered ceilings/visibility and mountain obscurations will
continue tonight through much of Monday as a weak mid level low
rotates through.
