As we move into the end of October and beginning colder months of November, the inevitable formation of nor’easter’s will become more and more common. Whether you like it or not, the first one of the season is already underway and set to impact the Northeast over the next 36 hours.

A large swath of moisture has already gathered across the Mid-Atlantic and is spreading heavy rains and strong winds well inland from the storms center. As our nor’easter moves northward tonight it will gain strength and pack a bit more of a punch across the I-95 corridor as well as locations much further inland. The coastline can expect gusty winds to peak near or above 50 mph late tonight and tomorrow morning, with gusts above 30 mph extending back across central Pennsylvania and Upstate New York. This will bring down some smaller trees and branches, in turn threatening power for millions across the Northeast.

Heavy rain will  be an issue with this storm as well, with widespread 1 to 2 inches of rainfall expected across most of the Mid-Atlantic and Northeast. A narrow band of 2-3 inches across the interior will also be possible where our deformation zone sets up. The immediate coastline will also experience rainfall in excess of 2 inches. These areas with higher rainfall totals could be at risk for seeing some flooding, but we don’t expect anything too significant. Coastal areas from New Jersey to Massachusetts could also see some additional risk from coastal flooding with a strong onshore flow.

As our nor’easter clashes with some cold air to the north, rain will become wintry over northern New England. What will start off as heavy wet snow for places like the Adirondacks, Vermont, New Hampshire and Maine will transition over to sleet and freezing rain. While several inches of heavy, wet snow are expected, ice accumulations may be more significant and cause more issues. We’ve highlighted our areas of concern below.

Our nor’easter will gradually move out of the region late tomorrow night and early Sunday, leaving behind much colder and windier conditions as the region dries out. A weak clipper system will quickly move in behind our storm, but shouldn’t do much besides some additional rainfall. Things should quiet down during the first half of next week.
