Discussion

Temperatures will stay below normal in the Mid-Atlantic as we head into the weekend and attention will shift to a storm that will cross the country dumping heavy snow in its path. By Sunday, a “primary” low pressure system will head towards the Ohio Valley after dumping heavy snow on the southern Rockies and central Plains, but as a result of the atmospheric roadblock that this system will encounter, the low will grind to a halt and transfer its energy to a developing “secondary” Mid-Atlantic coastal low. That coastal low will spread precipitation into the I-95 corridor from DC-to-Philly-to-NYC later Sunday into Monday and, while some of it will likely be in the form of rain, accumulating snow is also a real threat given this type of pattern; especially, in the northern and western suburbs and in higher elevation locations. The blocking pattern across Canada may prevent the coastal low from riding up the New England coastline so, as of now, significant precipitation is more of a threat for DC, Philly and NYC as compared to Boston and Portland (but still some time for that to change).
