Area Forecast Discussion
National Weather Service Missoula MT
212 PM MST THU FEB 26 2015



This weekend an arctic front will impact the Northern Rockies
causing very cold overnight temperatures. Several nights this
weekend and early next week will have wind chills in the teens
below zero from Butte to Georgetown Lake and north through
Garrison Junction and farther north over Marias Pass and into
Columbia Falls. This could be a very difficult time for newborn
livestock near the Continental Divide in Montana.

Tomorrow the first arctic arrives and will mainly bring wind and
cold with light snow. Most areas are expected to get less than an
inch of snow Friday and Saturday with this system, though some
locally higher amounts are possible in the mountains.

Monday and Tuesday another arctic front pushes west across the
divide. This time it has more moisture to work with, which is a
recent change in the models. PoPs were raised to account for this,
and it raises the possibility of significant travel impacts with
snow accumulating on roadways.



Clouds and a few snow showers will persist this evening along the
Continental Divide near KBTM and KSMN as well as north central
Idaho which could limit visibility, lower ceilings, and obscure
terrain at times. Northerly and easterly surface winds are
expected to increase with another arctic air push from east of
the Divide by midday Friday with gusty winds affecting western MT
terminals especially at KMSO. /ss
