DISCUSSION
Unseasonably warm and dry conditions will persist through the day tomorrow (Tuesday), as a ridge of high pressure keeps a firm grip over the Northern Rockies. While temperatures are not record breaking, they will, and have been running 10 to 15 degrees above normal for this time of the year. Above normal temperatures will continue into Wednesday for the majority of the Northern Rockies, just not as warm as it has been recently, along with breezy west winds and considerably more cloud-cover.
The ridge will begin to weaken late in the day tomorrow as the effects from a Canadian cold front banks up against the Continental Divide near Glacier National Park. At the same time, moisture moving through the northern periphery of the ridge, will allow for the development of mountain snow showers over Marias Pass late Tuesday evening and early Wednesday. A tightening easterly gradient ahead of the advancing cold front will also introduce breezy easterly winds along Highway 2 from Marias Pass to West Glacier Wednesday, ushering in much colder air.
The colder Canadian air-mass will be slow to advance further south into the rest of western Montana, not entering the rest of northwestern Montana until late Thursday. A shortwave moving onshore of the Pacific NW will bring light snow to most elevations north of Flathead Lake during this time, though only minimal valley impacts due to snow are anticipated. How far south the cold air advances remains relatively uncertain, with around a 65% chance of reaching as far south as Missoula by late Saturday.
A series of shortwaves will continue to traverse the Northern Rockies through the weekend, bringing modest snow accumulations to area mountain passes. As for the valleys, most accumulations through this weekend will likely occur during the overnight and early morning hours. Current projections have around 4 inches of snow accumulating during a 72hr period Friday through Sunday for the valleys north of I-90. While snow is likely to fall for area valleys south of the Interstate, accumulations are much more uncertain at this time. The mountains and mountain passes are more likely to see accumulating snow, with a 70% chance for 6 inches or more during the same period.
More seasonable temperatures and unsettled weather conditions are expected to persist into early next week.
AVIATION
Mostly sunny skies and generally light valley winds will continue through today. There has been an increase in terrain winds compared to the very light winds of the past couple of days, but these winds have been less than 20 knots.
