BOZEMAN – NW flow aloft is still anchored over Montana and it will continue to pave the way for several Canadian cold fronts to pass through the state from NW to SE.
The first in a series of storms is rolling through Montana Sunday night mostly east of the divide where scattered valley rain and snow has been impacting Great Falls to Billings and some of that moisture will clip a few counties in SW Montana through Monday morning. Area of greatest concern locally will be from Helena to Bozeman to Big Sky with valley mixed precipitation and snow over mountain passes like Boulder Hill, Bozeman pass, and King Hill pass.
If you plan on traveling Monday morning eastward to Billings plan on wintry conditions with areas of snow and wet roads turning icy early and improving by late afternoon.
2nd cold front will roll over Montana Wednesday. Ahead of that front temperatures will jump into the 50s but behind it fall into the 30s.
