FRIDAY, November 28 Discussion

GOOD to EXCELLENT smoke dispersion conditions are expected Friday as Arctic #2 begin's its approach. This one will approach us from the NNW as a developing low pressure center (in the mid levels) begins to drop SE from BC. Look for precip to start up in the ID panhandle and across NW MT during the mid-day hours and then spread Southward in the evening...changing over to snow after midnight. Transport wind flow will be breezy and from the West most of the day...though the N ID Panhandle could see winds switch around to be from the N late in the day. Latest model data has slowed the approach of this system a bit and is currently focusing the heaviest precip over NW MT and the N ID Panhandle down to around Moose Creek.


Extended outlook: 

GOOD to EXCELLENT smoke dipsersion conditions are expected Saturday as the stalled Arctic boundary drifts further south in to S MT and S ID. The snow associated with the front will begin to diminish as it moves further south. Transport wind flow will be slightly breezy and from the NW. Temperatures behind the front will be about 15 degrees below normal...not as cold as the last one.

 

GOOD to EXCELLENT smoke dispersion conditions are expected Sunday as a cold...but moderating Westerly flow lingers over the region. Lingering snow shower activity will be focused mainly across SC ID and SW MT...with only light accumulations expected.

 

GOOD to EXCELLENT smoke dispersion conditions are expected Monday as the warm front pushes north into Canada during the mid-morning hours taking the precipitation with it. Warmer air will move into the region...so all areas should see a significant rebound in temperatures. Transport wind flow will be from the SW and breezy in the afternoon.

 

GOOD to EXCELLENT smoke dispersion conditions are expected Tuesday as a strong cold front moves into the region from the West bringing mountain snow and valley rain showers to the the region. Transport wind flow will be from the west and breezy with the passage of the front. Additional significant mountain snowfall is possible in the mountains.
