The storm track hasn't changed much in the last three weeks. I'm forecasting a large, warm storm for the Northeast and some rain/snow for the Rockies this weekend. Cold air is hard to come by. A bunch of ski resorts are slated to close this weekend, and backcountry routes are making that transition to corn snow across the west. Once the resorts close, this will be our forecast’s focus.
Northeast: I foresee a few rain showers on Friday followed by a smaller storm clipping Maine with snow on Saturday. A second stronger storm hits Sunday afternoon continuing into Monday, but it looks warm with rain initially. Then, colder air filters in, changing the rain to snow by Monday morning. Light snow could linger into Monday night and Tuesday morning. Snow amounts look light—with most of the precip falling as rain.
Northern Rockies: A storm delivers rain/snow to Montana, Idaho and Wyoming on Saturday afternoon into Sunday morning. It will start as rain then change to snow over the higher elevations.
Colorado: A large, sprawling storm will continue to push waves of rain/snow through Colorado on Friday and Saturday—primarily near the divide and east. Accumulations could be heavy above 8,000 feet. Then, a fast moving cold front hits early Sunday with scattered rain and snow showers in the central and northern mountains and light accumulations on the highest peaks. I expect a few afternoon rain/snow showers on Monday afternoon over the high peaks as well. It's truly a spring pattern.
