NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Missoula Montana 
236 PM MST Friday Feb 5 2016 


Discussion...another weather disturbance will be making its way 
across the northern rockies later tonight through Saturday. As the 
system approaches the region, the pressure gradient will tighten 
creating gusty southerly winds on the Camas Prairie in Idaho. 
Grangeville could have wind gusts up to 45 mph later tonight into 
Saturday morning. Also this southerly wind will keep the 
atmosphere well mixed during the overnight hours, so temperatures 
for tonight should be relatively mild. Widespread precipitation is 
expected as the cold front moves through the region. During the 
onset of precipitation, snow levels will be fairly high causing a 
wintry mix in many valley locations. After the passage of the 
front by mid Saturday morning, snow levels drop to most valley 
bottoms. Mountain passes, especially along the Montana/Idaho 
border, will receive a significant amount of snow tonight through 
Saturday evening. Winter weather advisories have been issued for 
the travel impacts. The atmosphere becomes unstable enough for the 
development of hefty snow showers. The atmosphere profile 
indicates that snow bands will be possible by Saturday afternoon 
and lasting into the evening hours. Snow bands will be able to 
produce very heavy snow in a very short distance which will be a 
major impact on area roadways. At this time, it is difficult to 
Pin Point where and when snow bands will develop on Saturday. 


A strong ridge of high pressure will build over the West Coast 
extending into the northern rockies resulting in dry conditions 
Sunday through much of next week. As is typical with these strong 
Winter Ridge patterns, valley inversions will develop with the 
potential for low stratus, fog, and decreasing air quality. 
Seasonably cold temperatures are expected for valleys under the 
inversions, while higher elevation valleys and the adjacent 
mountains experience well above normal temperatures and frequent 
sunshine. 


By late next week, forecast models bring a cold front through and 
begin to breakdown the ridge but confidence is low on the timing 
and strength of the cold front. Most likely this will not be a 
significant event with much of the energy absorbed by the ridge. 


&& 


Aviation...a transitory ridge of high pressure has create fair 
flying conditions this afternoon and evening. The conditions will 
steadily deteriorate tonight as another system will make its way 
across the northern rockies. Ceilings will be steadily dropping 
tonight and widespread snow showers are expected by the morning. 
These showers will be capable of producing heavy snow, so 
visibilities could be reduced to less than a mile at times. Snow 
bands are a possibility by Saturday afternoon, creating another 
issued when the band is within the vicinity of the terminal. 




&& 


Air stagnation...confidence remains high that a strong ridge of high 
pressure will build across the region late Sunday and last through 
late next week, allowing valley inversions to develop and persist. 
Stable conditions will lead to decreasing air quality especially 
for the lower valleys of western Montana and Lemhi County in 
Idaho. The next potential break up of the stagnate conditions will 
be Friday or Saturday of next week as the ridge of high pressure 
gradually breaks down.
