A significant warm-up will occur over BC during the first half of this week, but periods of showers can be expected with snow levels rising higher each day. On Wed, snow levels will rise above ski resort summits with rain showers expected up to 2400 meters. On Thu, colder air arrives with lowering snow levels, early in the day over the Coast Range and later for the Interior.

After a steady stretch of chase opportunities in the past 30 days, we are entering a summer-like temperature pattern (80F in Denver on Thursday). WT-! Colder air moves into the PNW later this week, which should return snow to BC and the Cascades. Long-range models look decent for more snow in the Sierra and perhaps the Rockies. April could boom.

An upper-level ridge will bring warm spring conditions to the Western US to start this week as a colder storm system in the Eastern US brings light snow to the northern tiers. Spring in the West will be brief with a large storm system at the end of the week that will bring initial warm air and rain to the Northwest, but backside cold air with lowering snow levels and snow into the weekend.

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.
