Updates will be posted on the rain and snow event currently affecting the region. A few detailed updates will be posted in the bottom of this post, with most updates from Twitter.
3:55 PM: Since the last update, the coastal low affected the area, with moderate accumulations observed in NW parts of the area. Towards NYC and NE NJ, however, this is busting on the low side, with rain in NYC resulting in barely any accumulations, while a persistent dry slot in NE NJ just west of the banding with the coastal low prevented locations from picking up much more than an inch. Long Island has seen rain so far, although a changeover to snow is expected as the coastal low intensifies, with heavy snow expected for some areas.
With the latest observations, the totals have been again revised. For NW NJ and SE NY, 2 to 5 inches are still expected. In NE NJ, 1-3 inches are expected, with less than 2 inches in NYC and western Long Island. Higher totals are expected in eastern Long Island due to heavy precipitation from the coastal low tonight with parts of the island picking up 2-4 inches, with the highest totals in the area in eastern and central CT, where at least 4 to 8 inches of snow are expected, with locally higher totals above 8 inches towards eastern CT.
12:10 PM: Since the last update, the coastal low has continued to intensify, and is currently a 1002 mb low near eastern North Carolina moving NNE. Precipitation associated with the coastal low continues to expand and intensify, and moderate to heavy snow is moving into the area, mixing with rain in parts of Long Island. Heavy snow rates are expected up to 1/2 to 1 inch per hour especially west and north of NYC for the main part until the storm ends.
Forecast accumulations have been slightly raised to 1-3 inches in Long Island, 2-4 inches in NYC, 3-5 inches in NE NJ and SE NY, and 4 to 7 inches in southern CT. Locally higher totals may be possible.
