Winter is here. A genuine Arctic air mass is just to our north and it's just a matter of time until one pushes a little further south. Although it's around 40 here in NYC, in Montreal it's 14, in Caribou (Maine) it's 1, and in Quebec City, it's 0. (It must be fun walking up those giant hills this morning.) The dewpoint in Boston is -1 -- very dry air typical of an Arctic air mass.

The 10-day GFS computer model (called by its old name, the MRF, on that site) has been hinting at a period of storminess on the East Coast sometime early next week. This is a speculative prediction subject to huge changes, but it's nice to see the models getting into winter mode as well.
