The next 10-14 days are going to be wild across the Eastern US with multiple powerful storms tracking into the Northeast. A pool of cold Canadian air remains bottled up to the west with a general troughing pattern that allows very warm and moist Gulf of Mexico air to fuel winter storms.

There is a lot of QPF in the next 7-day forecast, and following that into mid-February. Where this falls as snow + temperatures e.g. how much Arctic air is in place = determine the snow ratios and potential accumulations. The ensemble snowfall maps that I create are using the 10:1 ratio as a baseline, you can increase or reduce easily depending upon the lower-level temperature profile. As you head further north into New England, the ratios will be higher, and I’ll show that our snowfall maps from the global models could be conservative!
