Unseasonably warm conditions exist in the west. Later this week, a cold front will move into the PNW and Sierra, bringing some snowfall back. Interior BC might be chaseable as well. Cold air tracks from the Sierra to the northern Rockies over the weekend while it stays warmer in the central and southern regions. Snow will return to the west with the colder air. The extended forecast might be deep!

A couple of nice days of spring in the West will turn to a stormy pattern with several rounds of snow through next week. Cold northwest flow will bring good powder conditions through many Western U.S. states. In the East, active storms will take a northerly track and bring rain, confining cold air and snow to the northern tiers.

An upper-level ridge and southerly flow will bring massive warming to the Northern Rockies through Thurs. Record daytime highs could fall on Weds and possibly again on Thurs. A Pacific storm system then spreads cooler temps and unsettled skies with periods of light snow falling from Thu PM through Sat PM. SW Montana, closest to the storm’s core, will see up to 6” by Sat PM. Mainly dry on Sun.

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.
