NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Missoula Montana 
251 PM MST Friday Nov 27 2015 

persistent dry and cold weather will continue through the weekend 
as the area remains between high pressure across British Columbia 
and low pressure over the Great Basin. Inversions will hold strong 
over the valleys, with morning lows dropping into the single 
digits and below zero, while daytime highs reach into the teens 
and 20s. Low stratus over the valleys of northwest Montana will 
continue, while low clouds and fog will likely become more 
widespread and persistent for the valleys of west central Montana 
such as the Missoula and Bitterroot valleys over the weekend. A 
few flurries may fall from the low clouds but the main impact will 
be reduced visibility and potentially slippery roads from patchy 
dense freezing fog. 

By late Sunday, the low pressure over the Great Basin will lift 
into northern plains which may lead to a few snow flurries from 
Lemhi County into southwest Montana but impacts will be minimal. 
Low clouds and fog are expected to continue to plague the valleys 
of western Montana early next week as inversions remain in place 
under a ridge of high pressure. 

There is potential for weak systems to penetrate the strong upper 
level ridge over the west by mid-week. Models may be overdone with 
the precipitation they spread over the region beginning about 
Wednesday. However, any frozen or freezing precipitation can 
rapidly lead to travel problems. Valley inversions will remain 
strongly in place for most of the week but with warmer conditions 
developing in the higher elevations by mid-week. There does not 
appear to be a strong enough system to remove valley inversions 
until at least next Friday. 


Aviation...stratus will continue to plague kgpi with low ceiling 
heights through at least the next 24 hours with little significant 
improvement. Favorable flying conditions is expected elsewhere 
with sunny skies and light winds this afternoon and evening. Clear 
skies tonight will once again lead to the development of fog or 
stratus for kbtm and kmso on Saturday morning. 


Air stagnation... 
stable conditions and inversions will continue through the middle 
of next week resulting in stagnant air which could lead to air 
quality issues, especially for the valleys of western Montana. 
Some improvement is possible late next week as the ridge of high 
pressure breaks down and valley cold pools gradually erode.
