6-Day NYC Forecast
Today
Windy and very cold with partial sunshine, snow showers likely, maybe even a heavier snow squall or two which would cause a quick accumulation, gusts up to 50 mph will generate bitter wind chills of near zero, highs in the mid 20’s
Tonight
Partly cloudy, bitter cold, very windy with wind gusts possible of up to 50 mph creating wind chills at or below zero, maybe a snow shower or two, lows near 10 degrees by morning
Friday
Bitter cold start to the day with mostly sunny skies, winds are brisk early, but quite calm by afternoon, maybe a snow shower, mid 20’s
Friday Night
Becoming cloudy, quite cold, snow likely to develop around midnight and there can be accumulations of a couple of inches by morning, low 20’s
Saturday
Cloudy, cold, early morning snow changes to a period of ice and then to plain rain by mid-day, but there can be an additional snow accumulation of a couple of inches before the changeover for a total of 2-4 inchesduring this event, mid 40’s later in the day
Sunday
Cloudy, mild, but turning colder late in the day, more rain is likely which can briefly change back to snow or sleet late in the day or early at night, near 50 degrees early
Monday

Discussion
The Arctic winds will howl today and tonight with gusts to 50 mph possible bringing wind chill values to zero or below at times. Actual air temperatures will be confined to the 20’s for highs and there can be snow shower activity at anytime and even a possible heavier snow squall or two that makes it all the way from the Great Lakes to the coastline. Any snow activity could put down a quick accumulation and cause slippery road conditions. Temperatures will likely bottom out early Friday morning in the upper single digits near New York City, not far from 10 degrees in the Philly N and W suburbs, and around 15 degrees in the DC area. In fact, some record low temperatures are likely to fall on Friday in much of the Northeast US. This bitter cold, dense Arctic air mass will then begin to retreat by early Saturday, but not before moisture reaches us from the Midwest and this potential collision of moisture and retreating Arctic air is likely to lead to some snow/ice accumulations in the region before a complete changeover to plain rain takes place around mid-day. Preliminary estimates for accumulations of snow/ice before the changeover to rain are on the order of 2-4 inches with the higher amounts to the north and west. Temperatures could very well then climb into the mid-to-upper 40’s later Saturday after the full retreat of the low-level Arctic air and more rain is likely during the afternoon hours.
The rain will tend to lighten up for awhile during Saturday night, but then it should return on Sunday as a low pressure system develops along the next Arctic front which will approach from the Midwest. Temperatures may actually peak near 50 degrees early Sunday, but then colder Arctic air will arrive during the late afternoon or early evening hours and it is possible that there is a brief changeover from rain to sleet and snow late Sunday or early Sunday night in the I-95 corridor. Following the passage of this next Arctic frontal system, the beginning of next week promises to very cold for the middle of December.
