Discussion
One cold front is generating snow showers in the Mid-Atlantic region this morning and the next front, in a long series of fronts, will push into the eastern states tomorrow night/early Saturday and it will likely generate more snow showers for the Mid-Atlantic region. Yet another disturbance will drop southeastward out of Canada by Sunday and it too could spark some snow shower activity in the region as we close out the weekend. By the middle of next week, we’ll be looking at the potential invasion of another bitter Arctic air mass and that cold shot could be preceded by some snow later Tuesday.
In fact, all indications point to a return of “deep freeze” weather in the eastern US beginning around the middle of next week and that colder weather pattern could last right into the early part of February. Longer range computer model forecasts from both the European and GFS (NOAA) are depicting an upper-level pattern that will feature a long wave trough in the eastern US and a long wave ridge along the west coast of North America by the second half of next week. The combination of these two upper level features will likely bring numerous Arctic air outbreaks into the central and eastern US from central Canada - perhaps for a two or three week period and right into the first part of February. It is too early to tell if we’ll get as cold as the early month “polar vortex” cold air outbreak, but Arctic outbreaks this time of year – climatologically the coldest time of the year – certainly can be noteworthy and I expect sub-zero readings to return to much of the northern US.
