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-!

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.
