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.
Significant storm numbers have been rolling in over the past 48 hours (see list below). Look for lighter snow tallies on Sunday, with another dose of higher-elevation snow over Sunday night. Snow levels rise rapidly on Sunday night under a sub-tropical SW flow. An upper-level ridge packing even more unseasonably warm air then builds in through Thursday. Cooler & back to snow Thu PM – Fri.
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.
