2:15 PM: Snow Gradually Ending, Another Storm Next Weekend

nerad254Following the late morning dry slot, snow resumed earlier this afternoon but with much lighter snow rates. Additional moderate bands of snow are currently moving through Connecticut and will continue to do so through at least 3-4 PM, falling with lighter rates in Long Island, while northern NJ, SE NY and NYC will continue to see occasional light snow ending mostly by 3 PM.

At the start of the storm, moderate to heavy snow fell as predicted along a narrow axis, with reports of 5-6 inches southwest of the area, but with the snow drying up over the area, less precipitation fell than forecast; the latest snow totals as of 12-1 PM were in the low end of the forecast range, near 1 to 3 inches for most of the area, locally up to 4 inches in NE NJ into Westchester county. These totals will be updated at the end of the storm.

Forecast Update: With fresh snow cover in place and a strong cold air mass moving in, cold temperatures will return for the mid week, with highs in the mid to upper 20s on Wednesday and the low to mid 20s on Thursday before slightly warming up on Friday. Cold overnight lows will be observed as well, in the single digits inland and 10s for the rest of the area, likely including NYC. The forecast highlight is next weekend, however, on Saturday, with another storm expected to affect the region with the potential for a widespread moderate or potentially significant snowstorm in parts of the region. At this time, the highest chance of higher snow accumulations is northeast of the area, with at least some frozen precipitation currently likely to fall, although this outlook is subject to change and more information will be posted with a more in-depth analysis to be posted on Wednesday morning.

12:00 PM: Snow Weakens

newradSince the last update, the snow band over the area has largely collapsed, especially over NE NJ and Connecticut, while snowfall become enhanced well north of the area over central NY state. Snow rates are beginning to pick up over central NJ, however, and will spread into NE NJ, NYC, Long Island and CT over the next 1-2 hours with additional light to moderate snow before the storm quickly ends between 1-3pm. The accumulation forecast remains unchanged, although some locations may see locally lower totals especially in parts of Connecticut.


10:10 AM: Moderate Snow Continues

1430Over the last 2 hours, moderate to locally heavy snow continued to spread through NE NJ, NYC and parts of Long Island/CT, with reports of 2-3 inches of snow in this area so far. Northwest of the heavier snow band, however, the presence of drier air is partially contributing to lower totals, with a coating to 1 inch reported so far in NW NJ into SE NY.

Snow rates are gradually expected to become lighter through 1-3 PM, when snow is expected to end across the area, with at least 3 to 6 inches of snow in the immediate NYC area into southern CT and 1-3″ elsewhere. Drier conditions are expected for the rest of the day into tonight with clearing skies and lows falling into the low 20s in NYC and the coast and 10s elsewhere.


8:10 AM: Moderate-Heavy Snow Moving In

1245As the frontal boundary shifted east of the region, a wave of low pressure is developing with widespread precipitation quickly moving through the region. The latest radar posted to the left shows moderate to heavy snow along an axis from southeast PA into NYC and locations just west. As the precipitation shield continues to extend northeast, this band will quickly move NE while gradually shifting to the east, with a few hours of moderate to heavy snow into NYC and southern CT with 3 to 6 inches of snow likely. Yesterday’s update included how far northeast the heavy snow shifts as an uncertainty, and it currently appears Long Island will see less snow than originally forecast, with 1 to 4 inches with the higher totals closer to NYC. Elsewhere in the area, at least 1 to 3 inches of snow are expected. The snow will be short lasting, and is expected to mostly move out by 1-3 PM.

    I ended up with about an inch of snow in Babylon. Like many have said, the ground was too warm.

      Ground temperatures do appear to have been an issue over Long Island and coastal CT where accumulations of at least 1 to 2 inches were reported, along with NYC which had temperatures between 34-35 degrees during the storm. Locations further northwest had colder temperatures, but with the majority of the precipitation limited to eastern NJ and Westchester county.
