The surface chart and radar Show high pressure over the area region With mostly tranquil conditions but cold over the region snow showers and flurries are up over the Great Lakes associated with the approaching system.
As I said yesterday We're going to have an area of low pressure up around the Great Lakes that's going to transfer energy to the coast and develop a coastal low south of Long island. This is going to drag an arctic cold front through the region. So temperatures are going to be well below average for this time of year. Winds will also be an issue! Winds of 10-20 miles an hour with gust of 30-50 miles an hour possible. These winds are going to create very brutal wind chills. So make sure if you go outside you're prepared for the cold. The NAM 10 mb Courtesy of tropical tidbits shows the tight isobars indicating strong winds.
The worst of the storm will be Friday night into Saturday.
Looking at the NAM courtesy of Tropical Tidbits we can see that inverted trough that I was talking about yesterday where the low pressure is going to develop off the coast and we're going to have that finger of moisture pointed towards eastern Long Island, Rhode Island,and eastern Connecticut into eastern Massachusetts.
For the most part We could pick up a dust into a couple of inches with the frontal boundary moving through. Along with this we could see a few squalls That could allow local accumulations to be higher. But as I was also saying yesterday and I show in the images above, we have to be watchful for all of this to overperform from New York City to Boston, especially over Long Island into Rhode Island, eastern Connecticut and southeast Massachusetts. Where a few inches of snow will be possible. Higher snow amounts will also be possible downwind of lake Ontario.
The coastal low will be pulling away Saturday night into Sunday. Conditions will become much nicer But it's still going to be very cold and windy. We could be dealing with like effect downwind of the Great Lakes.
Monday high pressure builds on and the cold will ease a little bit but it's still going to be quite cold. But winds will be much lighter. By Wednesday we will warm up to around seasonal levels. Then on Thursday we will be watching a system approach that will bring an interior snow, mix and for southern parts of the region rain.
