The messy warm storm continues in the central Rockies and Sierra through Friday. The parent, low off the coast of the PNW, continues to spin waves into the region, with cold air trapped in the PNW and northern Rockies and warm, moist flow aimed at the Sierra. A cold front advances into the Sierra and central Rockies Friday with chase-worthy snow.

February has come in like a lion this year with strong storms, heavy snow (and rain), and sharp temperature differences across the West and the East. An active pattern is expected to continue for the foreseeable future with frequent storms from coast to coast.

The AR will weaken on Tuesday and Wednesday, but continue to bring moderate snow to the southeastern half of Oregon. As the AR weakens, the semi-stationary storm off the PNW coast will bring snow showers through the Cascades on Wednesday and Thursday. Total snow accumulations will vary from 3-12 inches through the Cascades and 6-12+ inches from the AR. Cold air will keep snow levels low.

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.
