The easy forecast is that Tuesday through Friday will be warm and dry. Then the tough forecast begins, with some snow possible on Saturday and Sunday (March 29-30), additional snow possible early next week (March 31 - April 2), and then potentially a stronger storm later next week (April 3-5).
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.
