In reality, it just ain't that way:
First of all as noted, the 90.2 inches of snow in the last 23 days in four nor’easters came from 5.02 inches of water. This 18 to 1 ratio is well above the normal 10-1 ratio in the ‘average storm. It is because the air is so cold with snow during the events falling with temperatures mostly in the teens.
Also there is no evidence that the water just east of Cape Cod is 11.5 (21F) above normal as tweeted. NOAA’s National Hurricane Center Analysis showed water no more than 2 or 3C above normal well to the east of Cape Cod and with the very cold weather this month (over 11F below normal in the northeast), the water near the coast is colder than normal with ice forming. Ice is seen as far south as off the New Jersey Coast and will likely clog Boston and New York Harbor in the brutal cold of the next 10 days. Freezing spray warnings are in effect in the waters around NYC this morning.
