After a cold however dry Friday, clouds enhance later within the afternoon and precipitation will ramp up at night time. Temperatures aloft are above freezing, so the precipitation will develop as rain.

In a single day – almost certainly after midnight – floor temperatures within the advisory space will dip beneath freezing.

We gained’t get a thick layer of ice, so tree limbs must be unhurt. At greatest, we’ll get a couple of hundredths of an inch. However in the case of ice, the very thinnest of glazes make driving treacherous.
Don’t be fooled: A glaze of ice on a street or sidewalk appears to be like precisely like moist pavement. You solely notice it’s ice if you slip and fall or your automobile slides uncontrolled, so assume it’s ice and never water. Any untreated roadways, sidewalks, steps might grow to be slick.

These areas will dip to beneath freezing in a single day.
It’s possible you’ll marvel why, if the temperature drops beneath freezing, we wouldn’t get snow as a substitute of freezing rain. The kind of wintry precipitation we get, sadly, takes extra into consideration than simply floor temperature.
Temperatures aloft are crucial in figuring out what kind of frozen precipitation falls. Within the case of freezing rain, the air above the floor is above freezing, permitting the precipitation to fall as a liquid.
Solely a skinny layer of sub-freezing air is nestled near the floor. That causes the liquid to freeze as soon as it hits the floor, creating freezing rain. With a barely thicker layer of chilly air, the liquid would freeze earlier than hitting the bottom, leading to sleet.
Fortunately, any ice that does fall is not going to be sticking round too lengthy. Temperatures in all places within the tri-state might be again above freezing by Saturday afternoon, and can proceed to rise from there.
From that time via the top of the 12 months, precipitation likelihood is going to be all rain.
The following spherical of rain will arrive later Sunday.

Yr thus far, the tri-state continues to be working practically 4 inches beneath common rainfall totals. It’ll be good to place a dent in that deficit earlier than the 12 months ends.
The regular rain mixed with the gentle temperatures will wipe out any remaining snowpack in our area.
In areas like northwest New Jersey and the Hudson Valley, the place a couple of inches of snow are nonetheless on the bottom, minor river flooding is anticipated. The fast inflow of melting snow together with the regular in a single day rainfall will contribute to the rise of rivers and streams, resulting in some minor flooding, particularly in low-lying and flood-prone areas.
Common excessive temperatures this time of 12 months are round 42 levels. Nevertheless it has been every week since we’ve seen temperatures even attain the 40-degree mark in Central Park.
