The jet stream will dip south Sunday into Monday. Cold air will pool in with that dip in the jet stream so temperatures will quickly drop. As the temperatures drop and the northerly winds work up the mountains, rain will switch over to snow.
The Northern Rockies from Wyoming to Colorado will get a good amount of snow starting on Sunday evening into Monday. The National Weather Service has already placed many locations under winter weather alerts for the upcoming snow.
Some locations in the Snowy Range could receive over a foot of snow. The lower elevations could 5 to 8 inches of snow even.
Areas around Denver could have a messy Monday morning commute.
The mountains, which saw their first significant snowfall just last week will get another round but so will the lower elevations. 4-7″ of snow is forecasted for locations near Denver and Boulder. The heaviest amount is likely to be located along the foothills.
This snow will be heavy and wet so power outages may become an concern.
TIMING: Sunday night into Monday.
WHERE: Northern Rockies and down I-25 from Cheyenne to Denver.
The snow will be a quick event and end later Monday but the cold sticks around into Tuesday. Freeze Warnings and Watches are in place near and east of I-25 for Colorado. Temperatures will still be very cold into Tuesday.
Not a fan of winter’s early appearance? Don’t worry. Temperatures start to rebound come Wednesday.
