First Alert 48 Hour Forecast

Saturday starts off with dry skies, but by the afternoon wet weather returns to northwest Montana.  Southwest Montana stays dry all day with partial sunshine.  High temperatures end up a touch above average in the mid 30s.
By Saturday night, the entire region runs into the shower activity.  This is a relatively warm system, so the valleys are mainly staring at rain.  Mountain passes will get pummeled by snow.  Travel over our mountain passes will be tough on Sunday.

Monday and Tuesday appear to be relatively quiet days with just some isolated shower activity.

The potential still stands for a more potent snow storm sometime between Christmas Eve and Christmas Day.  This one will bring enough cold air with it for all valleys to have a good chance at shoveling some snow.  Nice little Christmas present from Old Man Winter...
