Pattern to get cold and stay active.

 Surface chart and radar

Looking at the chart and radar we can see we have a couple little shortwave troughs coming through, with a bit of lake effect coming off lake Ontario and a few very isolated snow showers elsewhere. Accumulations are going to be very light.

Temperatures are seasonal coolish today. With the breeze adding some wind chill. Play all in all It's a nice day outside compared to where we have been. Tonight we will see the temperatures once again cool off quite a bit. Leading to a cold start tomorrow with temperatures recovering back to generally where they are today. Then we will be watching a system approaching the Great Lakes.

But we're on the verge of another insertion of arctic air

Late Thursday into Friday we're going to have low pressure moving into the lakes Dragging an arctic front with it. As the low pressure gets up over lake Ontario we are going to see it transfer it's energy down to the coast south of long island. As the arctic boundary is coming through we will likely see Snow showers develop. These snow showers could be briefly heavy. That could produce a dusting to a couple of inches of snow, due to the cold temperatures. We will likely see lake effect snow develop especially off of lake Ontario that could add a few inches on top of what is coming with the frontal passage. Most of the region shouldn't be hugely impacted from any of this. But with the front we will see winds becoming quite gusty The gusty winds are going to last through the coming weekend; Making for extreme wind chills once again! 

I did say most of the region. As that low transfers To the coast The trough looks to become negatively tilted This will help direct an enhanced flow into southern New England and Long Island. The EURO and GFS are very similar in their look, The other models support the idea to various degrees.

Both models show that inverted trough That is directing the flow Southern New England and Long Island, Including New York City and the Lower Hudson Valley. This could very well help enhance the snowfall rates between New York City and Boston. Somewhere in that area we'll see the storm likely overproduce. Possibly resulting in a hefty snowfall due to the cold air and high liquid to snow ratios. New York City and western Long Island could get into this. but I think a bigger focus will be on eastern Long Island, eastern Connecticut, Rhode Island into eastern Massachusetts. Could this make it into Boston? I'm not sure. All of that is gonna come down to the timing and exact placement of everything.

This looks to be pulling away later Saturday, with high pressure building in for Sunday. As I said Winds are going to be very breezy over the weekend So with  these very cold temperatures in the teens to single digits wind chills will likely be well below 0. So make sure you dress in layers and limit your time outdoors as frostbite can set in in a matter of minutes.

Monday and Tuesday of next week we'll see temperatures moderate a little but it's still going to be quite cold. We could have a clipper like disturbance try to push through on Wednesday. If this does occur it looks to impact southern New York State, Pennsylvania and into the northern Middle Atlantic.  But right now If it does form,; it doesn't look to be that big of a deal.
