NEXT WEATHER MAKER
A pacific storm system will push into the western half of the country Friday and reach the central and northern Rockies by Saturday. As this storm moves eastward it should weaken before reaching SW Montana, but the overall forecast is calling for widespread snow Saturday night through Sunday evening.
Warmer air will roll up ahead of this storm Saturday and combined with increasing surface winds temperatures could hit the low to mid 40s Saturday.
The one issue with warm air advection ahead of a storm system is mixed precipitation could develop Saturday evening and as the colder air digs in Sunday snow is likely. Wet roads could become icy Sunday into Monday morning.
