Rain, wind, and even snow possible this weekend

An energetic mid and upper level disturbance will shift from Central Canada through the Northeast United States late this week into the early part of this weekend, helping to develop a coastal storm. In addition to the coastal storm will come a strong cold front, and a cold Canadian airmass which will drop temperatures into the 20’s and 30’s at times after its passage. With models hinting at the development of multiple surface lows off the coast, the potential exists for not only rain and wind — but some snow in the higher elevations and the first flakes for others as the storm develops.

But the setup remains extremely complicated. The source region of the disturbance means forecast models are already working with a somewhat limited dataset. And, as is often the case with storms in our area, the mid level disturbances will be involved in fragile interactions, all of which will have a major impact on exactly how the storm develops. Confidence, as a result of these small nuances and features, remains very low. The general idea of a strengthening coastal storm passing along the East Coast, however, is gaining traction quickly.
