The next storm is on our doorstep with cold air and decent snowfall totals for the Front Range. Utah is a wildcard in the Cottonwoods for lake enhancement in the Cottonwoods. The long-range has higher confidence of double digits for the PNW and Northern Rockies, with the Sierra on watch (January 27-20)

An arctic front is moving through on Friday morning and snow is falling across the Tetons. Snow will be scattered and showery in nature with most areas picking up 1-3 inches as moisture will be limited. Totals will be higher east of the Divide. Arctic air will settle over the area Sat to Wed with frigid temps, possibly getting down to -20º or lower in the valleys. Next chance of snow is Jan 24-26.

The big story this weekend will be arctic air overspreading much of the Lower 48. The large-scale pattern will continue to favor drier conditions across the West with only some light snow for the Rockies, while the East will be more active. Two storms will move across the East over the next 3 days, while the South could see snow next week. The Great Lakes will also see consistent snow showers.

High-pressure flattens on Thurs PM as a Gulf of Alaska shortwave rides out of BC, bringing periods of light snowfall across the Montana Rockies through Fri. Most locations will see anywhere from 1 – 4” by midnight Fri. Also, on Fri, an Arctic cold front will move into the Northern Rockies out of Alberta, starting an extended period of the coldest weather we have seen this winter through next Weds.

Thanks for reading this summer! For the rest of this week, a cold front moving across the Central Rockies will bring showers & t-storms to WY, CO, & NM Wed-Thu while the West Coast states will see a late-season heat wave. Next week, isolated to scattered showers & t-storms develop across the West with continued mild temps. Heading into mid-month, the PNW will trend wetter and cooler.
