Summer might still be with us, but that doesn’t mean it can’t snow. After all, it is 2020, so anything’s possible. The NOAA has issued a hazardous weather outlook and is calling for the potential of snow in northern Wyoming above 10,000-feet and to the mountains of Montana, dropping as low as 6,500-feet in Glacier National Park.
Wyoming - A strong cold front will quickly push south to the Continental Divide Sunday ushering in much cooler weather to the region with a chance of rain Sunday afternoon and Monday evening. The rain will likely change to snow above 10000 feet with minor snow accumulations possible in the northern mountains.
Montana - As far as precipitation is concerned, on Sunday scattered showers will be mostly confined Northwest Montana and along the Divide. Snow levels drop to around 6500 feet, so an inch or two of snow is possible in Glacier NP. By Monday, a secondary disturbance will bring a round of showers to much of the region.
It won’t be much, if anything, and it’s not like we’ll be out making turns, but it’s a pleasant reminder that winter is just around the corner.
The NOAA forecast discussion explains:
By Sunday evening the cold front should be across southern Wyoming. While models have trended drier, the best chance for appreciable precipitation with this wave will be across northern and eastern areas through midnight. With much cooler post-frontal temperatures some of this will fall as snow across higher elevations during this time, mainly above 9,500 feet in the Bighorns. Monday morning lows are expected to be cool everywhere, but especially across western Wyoming where a freeze is still looking possible with clearing skies. Similarly, a much cooler Monday afternoon is expected with highs generally in the 60s and 70s across the forecast area.
