A powerful storm system continues to deliver strong wind, heavy rainfall, and high elevation snowfall to the Pacific Northwest. Timing it out, precipitation moves from the PNW into ID/WY/MT/UT/CO through 3/28 and 3/29. PNW air temps are very warm initially then colder air moves in on 3/28. This should help to bring the freezing level (rain/snow line) back down to lower elevations. Places along the Pacific coast can expect heavy rainfall with a few inches of accumulation possible.
