A lot of active weather is expected through the weekend across parts of the country with rain, accumulating snow, and severe storms all likely.
In the Northeast, more accumulating snow is expected today as a low-pressure system moves into and through New Brunswick, Canada. The higher totals are expected to mainly be in ME where up to 6 more inches may fall, and lesser amounts further west in NY, VT, and NH.
Further west a major storm will affect much of the central part of the country with wintry weather in the north and severe storms in the south. Precipitation is expected to increase in coverage this evening and overnight in the northern Rockies and move southeast into the central Plains before heading northeast into the Midwest. The best chances for accumulating snow will be in central and eastern MT, western SD, northern NE, northwest IA, Southeast MN, and central WI where models are in most agreement. This swath of snow can still shift northward or southward and will depend on the progression of unseasonable cold air building southeastward from Canada. On the southern part of this system, an upper low is expected to become an open wave as it moves from southern CA eastward through the southern part of the country through the weekend and will set up the potential for severe storms. Today, there will be a chance, but the lesser chance over the next 3 days will be in west TX and east NM. Severe storm chances will increase over the weekend as the threat builds east with central and eastern TX having the better chances on Saturday, and an outbreak of severe weather is looking possible on Sunday from east TX to the southeast states.
