Radar shows the snow moving north and east across the region. We have a trough pushing east across Pennsylvania and New York State, with low pressure over the Carolinas, which is transferring its energy to the Coast. This will ride up the Coast.

Snow looks to reach Boston around 5-6 PM and then for Maine 8-9 PM

Here is my latest and final snowfall map for this storm. These are general amounts so there could be lower or higher amounts in parts of these areas. But I think there is a greater likelihood for the amounts to be on the lower side rather than the higher side. The track has changed a little. But we have dry air overhead, it will take awhile for that to moisten up, before steady snow falls, with the cold air, this will be overall a fluffy snow, with perhaps a little bit of wetter snow to start. So forecasting snowfall is tricky. 

NWS watches and warnings

This is a fast-moving storm and it will be pulling away tomorrow morning.

Dry air on the onset, which would eat up snow before it hits the ground. (If it doesn't hit the ground, it isn't measured, and it doesn't count)

Colder surface temperatures, which you can usually squeeze out a lot of moisture from.

We have an arctic airmass moving into the region, due to arctic high pressure in the Plains with a lobe of the Polar Vortex just to our north in Canada. This airmass originated in Siberia so the temperatures will be very cold, with a good chance for daily record high/lows being broken for many of us. As the storm ramps up, winds will become very gusty into Wednesday. This will make for dangerous windchills. So remember your cold weather safety rules. The cold could also lead to some power outages across the region, so have a plan in place incase that happens.

Lake Effect snow, with the arctic air moving over Lake Erie and Lake Ontario, those east of the Lakes will likely see another significant lake snow event with feet of snow falling Monday through Wednesday.

Here is a forecast map from NWS Buffalo for the Monday through Wednesday lake effect event.
