Snow and sleet accumulated to 4.7" at 1000ft in Keene, NH. At this point, sleet has changed to all rain. Portions of northern Cheshire County may continue to see sleet through this evening. Snow will be confined to northern and central NY, VT, NH, and western ME through tomorrow. In these areas, snowfall totals could locally exceed two feet. Rain will fall moderate through 8pm, and then heavily through tomorrow. Already, parts of CT, SE NY, and NJ have reported rainfall amounts over 3 inches! And the storm is still yet to come.
Redeveloped low pressure has stayed south of the NC/VA border all day today, and is now about to exit the NC coast. This low has strengthened rapidly over the last 6 hours. Latest surface maps indicate pressures of 984mb in northeast NC, however station reports have dropped to 982 in the area. This is about 2 to 3 hours ahead of the model guidence. Also, the low is much slower to exit the coast than forecasted. It still has a slow journey up the eastern seaboard, during which this low could even go below 970mb!!! Pressure falls of 1 to 3mb per hour have been shown for the past 6 hours about 30 to 40 miles east of the coastline. This is indicative of a more eastward future track.
Now the concern shifts to flood potential and wind potential. Cheshire County is currently included in the flood watch outlining amounts of 3 to 5 inches with locally 6 to 7 inches of rain. With the current snowpack, we could see moderate flood problems tomorrow through Wednesday. Meanwhile, already coastal New Jersey and Long Island are reporting wind gusts of 40 to 50mph, with a few reports of 60mph gusts. These winds will only increase as the low approaches the area. Moderate to major coastal flooding is possible for New Jersey to Long Island and Cape Cod and the Islands.
Another aspect of this storm much further south is severe weather. Tornado watches have gone up for parts of Virginia and North Carolina. Thunderstorm potential exists up into SNE tonight as the storm lifts north.
So all in all a potential historic nor'easter on our hands tomorrow. Stay safe and dry.
