A strong nor’easter/coastal low will impact NYC tonight into Saturday. Conditions will deteriorate with the worst weather overnight into tomorrow morning. Gusty winds, soaking rains will accompany this storm. Temperatures will also drop as the storm moves off northeast and winds turn to the north and northwest, however, cold air wrapping around the low will not arrive in time to set the stage for accumulating snow here. Storm clears out by later Saturday. Afterwards, calm, seasonably cool temperatures (low-40s) are in store for next week.

Rest of today – temperatures topping out in the upper-40s with warm air advection/warm front moving up ahead of the main storm. Cloudy, with chances for rain increasing through the day, mostly on the lighter side. Overnight lows largely holding steady in the mid-40s again due to the influence of the incoming warm front. Rain expected to increase in intensity overnight going into Saturday morning.

Saturday – models are in pretty good agreement (see above images from GFS and ECMWF models depicting evolution of this storm during the day Saturday) that this coastal storm will evolve quickly and intensify as it tracks offshore southeast of the region. This will result in periods of rain throughout the first half of Saturday, along with increasingly strong winds as the pressure gradient tightens around the deepening low. As the low tracks northeast, winds will be turning from the south to the north and northwest. This will bring in much cooler air, although not cold enough to support accumulating snow at the coast. As a result, temperatures will be dropping during the day Saturday into the low-40s. Precipitation should end rather quickly in the afternoon. Overnight lows will be in the low-30s wit winds easing.

Sunday – sunny with high temperatures in the low-40s. Overnight lows around 30ºF.

Monday – similar day to Sunday with sunny weather and high temperatures in the low-40s. Overnight lows again around 30ºF.
