...WIND AND SNOW REMAIN WEATHER IMPACT THROUGH TODAY...
...OVERNIGHT/MORNING VALLEY FREEZING FOG TUESDAY TO SATURDAY...

.DISCUSSION...

Gusty winds and occasional snow will continue to be present over
the Northern Rockies through today. Despite the fact that the
heaviest snowfall and the strongest wind speeds may be past, do
not be fooled. A resurgence in winds today will likely continue
the snow redistribution across previous cleared roads. Also, the
snow and wind will reduce visibility at times. Hazardous driving
conditions will result, particularly over area mountain passes. By
this evening, relief in the form of weaker winds and a rising
freezing level will arrive.

Tuesday through Saturday, high pressure will be the main weather
feature over the Northern Rockies. High elevations will warm up a
bit, while daytime temperature inversions develop for many area
valleys. Also, the recent snowfall in area valleys will allow fog
and freezing fog to develop each overnight and morning. Watch out
for sudden decreased visibility and icing on pavement within the
fog patches.

Extended forecast models agree upon the next storm cycle beginning
over the Northern Rockies by early next week, however the
characterizations of wind and snow impacts are still evolving.
Precipitation features depicted by model guidance this morning are
definitely weaker than those noted during the past two days,
however there is low confidence instilled with such dramatic
shifts in model solutions in the day 7 to day 8 time frame.

&&

.AVIATION...Gusty winds and occasional snow showers will continue
to be present at times for all Northern Rockies terminals through
14/0000Z. Snow showers will rapidly and temporarily decrease
ceilings and visibility, however these conditions will become
steadily less likely throughout the day. Winds above the terrain
ridges will be much stronger than the surface winds and may cause
dangerous mountain wave activity. Terrain will continue to be
obscured as well. After 14/0000Z, conditions will begin to be
consistently improved, both at area terminals and aloft.
