The storm system that brought 1-3 feet of snow to parts of ND and MT continues east through eastern Canada the next few days but will continue to affect the eastern part of the country. A cold front draped well southward from this system will move from the Great Lakes and Plains into the Southeast through the weekend and will be the focal point for precipitation. Shower and storm chances will be from northern New England to the Southern Plains today then build into the Southeast into the weekend. A few severe storms are possible with some of this activity, but heavy rain may be the greater threat with widespread rainfall amounts of 2 inches or more from eastern OK to northwest SC. A change over or mix with snow is expected in New England with snow accumulation possible in NY, VT, NH, and western ME.
In the west, the next trough moves in with initially isolated to scattered rain/snow showers today in the Pacific Northwest and Northern Rockies. Precipitation begins to increase in coverage beginning this evening/overnight in northern CA and OR and builds east through the Northwest and into the Northern Plains and Upper Midwest through the weekend. More snow accumulations are looking possible for ND, and also possible in parts of MN and IA.
