WEATHER DISCUSSION: The major weather pattern change is now in place across the west and a significant fall storm continues to impact the Pacific Northwest. As an upper level low pressure system passes by, the wind shifts to the northerly direction allowing temperatures to cool below freezing for lower elevations of central Montana. The transition from rain to wet snow will happen from west to east late Saturday night through late morning Sunday. It will also be breezy with gusts up to 40 MPH Saturday night and Sunday.
Behind the storm system, very cold air will be in place as temperatures fall into the 10s and 20s Sunday night and Monday morning. It will also remain breezy behind the storm system through at least Wednesday. Wind gusts as high as 60 MPH are possible for the Rocky Mountain Front, up to 45 MPH throughout the rest of central Montana. The weather turns active again, especially for higher elevations, during the middle of the week with another system bringing rain and snow showers to the region.
