At or below freezing temperatures have worked down into the NYC metro and as far east as interior SW CT. Due to the shallow nature of the cold air, it has struggled to get across the hills of western CT. The Hudson River Valley has made it easier for a more southward progression initially. As the colder air gradually deepens, it will continue to expand south and east across CT and LI. Winter weather advisories remain in effect until 7 pm for all but SE CT and eastern LI, where it is in effect until 10 pm. Far eastern areas will likely not see freezing rain until around 00Z (give or take an hour). An additional tenth to quarter inch liquid equivalent is possible before the event comes to an end for far eastern areas late this evening. This will result in up to an additional tenth of an inch of ice across interior sections of CT, with a light glaze down at the coast. Upper portions of the Lower Hudson Valley will likely go over to all sleet with little additional ice accretion. Some areas have seen close to half an inch, with some reports even higher up above 500ft. High pressure over the Midwest will then build slowly east overnight, while the departing frontal system works across the western Atlantic. Much of the night will remain overcast with strong cold advection on N-NW winds at 10 to 15 mph. Lows by daybreak will range form the lower to mid teens well inland, to the lower 20s at the coast. This is a few degrees below normal.
