DISCUSSION

/Issued 219 PM MST Tue Nov 10 2026/

A quick moving and weak upper level shortwave trough continues to push through the area today, which is resulting in a breezy day across North Central Montana, with Southwestern Montana seeing a calmer day today. This system will exit the area later this afternoon, after which upper level ridging will quickly build across the Rockies and up into Central Canada, which will result in a short-lived omega block over much of Canada and the United States. On the surface, expect temperatures to soar to 15-20 degrees above climatological norms for mid-November Wednesday through Friday, with slightly cooler, but still above average, temperatures over the weekend when the ridge axis shifts a bit further eastward.

As we head into the weekend and beyond, a series of strong upper level lows will move across the Pacific and into the West Coast. While how exactly this plays out is a bit uncertain, but overall expect a period of unsettled weather pattern with multiple opportunities for mountain snow and valley rain or snow as multiple systems embedded in the upper level flow push onto the west coast. Looking further into the middle of next week, the overall trend is for some version of a cooler pattern as cold air surges southward. Ludwig
