Heavy rain in the east and accumulating snow are the weather stories through the weekend.
First, in the east, a cold front will be draped from New England to the Southeast early today and will move offshore later today, and will be the focal point for showers and maybe a few storms today and lingering into part of Saturday. Some of the rain could be heavy today into this evening from the Mid-Atlantic to New England and continuing into the overnight and early Saturday in eastern New England. Much of the rain should be over by early afternoon and maybe lingering into the evening in eastern ME. High pressure builds in on Sunday bringing dry conditions back to this region.
Further west two systems will bring rain and snow to areas from the Pacific Northwest to the Plains and to the Midwest. The main activity will be in the Northwest today and make it into the Dakotas late this evening and overnight, and then the Upper Midwest on Saturday before heading into Canada on Sunday. Accumulating snow is likely on the northern side of this system in the Northern Rockies, northern ND, northern MN, and possibly parts of northern WI. The next system will quickly move into some of the same areas for Saturday night and Sunday, but building a bit further south into the central Plains than the previous system. More snow will be likely in the Northern Rockies and the accumulating snow threat builds southeast throughout Saturday night into eastern WY, southwest SD, northern NE, and possibly into central and southern IA and southern WI by Sunday morning.
