Winter Weather Advisory Coastal Flood Advisory & Warnings Posted 11172019
Winter Weather Advisories are up overnight for Northwest New jersey & Northeast Pennsylvania. The advisories extend eastward into the Hudson Valley across Orange and Dutchess Counties into Northwest Connecticut. The advisories extend northward to north of I-90 into NY State and then east into Vermont, New Hampshire and Massachusetts. The primary issues overnight into Monday is for freezing drizzle or some light freezing rain that will develop overnight in some areas particularly in valleys where cold air is likely to be trapped.
Not much has changed from forecasts from earlier today regarding ice accumulation amounts. Glazing looks to be mostly on the light side as most of the heavier precipitation will be closer to the coast with far less as you head west across New England and into NY State and New Jersey.
Not much has changed regarding the snow forecasts across the Northeast. Much of what will fall snow wise will likely come Monday night into Tuesday as the low moves northeast toward Nova Scotia and the upper air trough swings closer to the East Coast. From the standpoint of snow and ice this is a minor event. Higher amounts will occur in Northern and Northeast New England from this system.
The track of the low is far out offshore and it is really more from the strong upper features that will be generating precipitation rather than from the low itself which sits well to the southeast of North Carolina. In fact the low is so far offshore that there is very little on the radars close to land near the low center.
On the local radars there is very little going on anywhere at the moment. Drizzle or light rain could be occurring beneath the radar beam and some areas are reporting some patchy drizzle or light rain that is laying in the bottom 1500 to 2000 ft of the atmosphere. Not much if any steady precipitation occurs overnight.
LOCAL RADAR NEW YORK CITY
Some steady precipitation develops during the day Monday as depicted by the ICON model loop above. The GFS is way over done and the NAM perhaps a bit underdone with all of this. Colder air changes rain to snow in Upstate NY Monday night into Tuesday morning. Rain if any comes to an end from Eastern Pennsylvania to Southern New England later Monday night or early Tuesday with improving weather conditions to follow. As to temperatures they will be in the 30s to low 40s overnight with some areas where Winter Weather Advisories are up seeing temperatures under 32. Highs Monday should reach into the 40s in most places and lows in the 30s overnight. Tuesday’s highs will be in the chilly 40s.
