Kammerer is calling for a total of 14 to 20 inches of snow this winter along the Interstate 95 corridor, with more north and west, and less south and east.
Many different factors go into crafting the winter outlook. One is the amount of Siberian snow cover spotted in late October and this year’s was one of the largest ever seen. But more snow over there doesn’t necessarily translate to more snow here — it’s just an indicator for a potentially colder winter.
Kammerer says that — along with record low amounts of Arctic sea ice — will help very cold air move into the area in and around the nation’s capital.
