As the snow part of the storm comes to an end, Montana is entering the coldest part of this stormy cycle.  A WIND CHILL WARNING is in effect for the Hi-line with wind chill values as low as -45 tonight.  Frostbite can occur in minutes in these conditions.  Please use extreme caution if you plan on travelling through that area.  A WIND CHILL ADVISORY is in effect for a most of central and eastern Montana into Saturday as well.  Arctic high pressure will settle over the state tonight into Saturday morning.  Clouds will clear and temperatures will drop to below zero for most of the state.  Saturday will start out cold and sunny.  Strong west wind will develop off the Rocky Mountain Front with the potential of blowing snow.  Highs will be in the 10s and 20s, but only in the 0s in northeast Montana.  Sunday, another shot of cold air and snow will move into the state.  Light snow will spread across a lot of Big Sky Country by the afternoon.  Temperatures will fall back into the 0s.  Monday will be clear and cold as another high pressure moves in from Canada.  Tuesday, a warmup with a lot of wind is likely for most of the state.  Temperatures will warm above freezing, possibly into the 40s.  Snow will begin to melt, but a sharp cold front on Wednesday will drop temperatures back into the 0s.  A flash freeze is possible for a lot of the state on Wednesday with snow moving back in.

The active weather pattern will continue into next weekend as a series of Canadian cold fronts keep reinforcing cold air with snow.  Winter is far from over.

Be safe! Have a great weekend!
