Snow maps, the Arctic blast, and then we start to focus on the storm for next Monday:

The snow maps and details for Long Island are shown below for the system today into Wednesday. The Thursday storm will stay south of Long Island and well southeast of New England, and then a blast of Arctic air arrives for Thursday night until Sunday morning. It will then moderate as the next storm approaches Sunday night into Monday. While there is still a lot of uncertainty in the track and details, it generally looks like a snow to rain event for Long Island, but some initial accumulations are possible. There should be some fairly significant accumulations for parts of New England. As I'm sure you could have guessed, I will be posting about it frequently going forward.
