Temps steady at night Sunday night, with plenty of cloud cover. Only precip of note through the period would be very light rainfall on Monday night with the passage of a cold front. 

3. Tuesday night and Wednesday, we have a good shot at light rain, ending by afternoon on Wednesday.  Thursday is dry with temps in the upper 40s. Another shot at light rain will try and work through the region on Friday.

MAJOR WINTER STORM ON THE WEATHER MENU FOR WEDNESDAY AND WEDNESDAY NIGHT

Incredibly, after record high temps for Monday, the stage will be set for the region's first significant winter storm of the season.

The primary hazards associated with this vigorous storm will be most felt north and west of Interstate 95 and points north and west; the primary weather hazard will be heavy snowfall which will make driving very difficult for Wednesday afternoon and evening.

A light rain-snow mix will overspread the region as early as overnight Tuesday night/Wednesday morning. However, the steady, more meaningful precip will get going late Wednesday morning, and continue heavy at times; snow will change to rain for NYC and points south and east, cutting down somewhat on accumulations there. However, north and west of NYC and the coast, snow will take over as the primary precipitation type.


As the low pressure begins to pull away, a period of snow will take place all the way down to the coast during sometime Wednesday evening; this is the best opportunity to see a quick accumulating snow at the city and coast, where a general 2-4" is a good possibility. Areas in and around the north shore of Long Island at the highest elevations could see amounts closer to 6" by the time it's all over!

if you must travel, leave early and in the morning hours if possible, especially if you're driving from south to north.

In the pre-dawn hours of Thursday, all precip will taper off.

Behind the storm, it's unseasonably cold and dry through the weekend, with a noticeable warm-up by Sunday.
