A quick moving system will bring snow to the region today and tonight. Snow is already beginning to fall in the western mountains...this activity is expected to continue through the evening with over a foot of snow possible across the higher elevations and 2 to 4 inches across much of the western valleys...with locally higher amounts expected in areas favoring westerly flow. A cold front associated with this system will move west to east across the area this evening...bringing snow east of the divide and setting up a period of upslope flow in Casper, Lander, Riverton, and Jeffery City this evening.
