Negative phase of the Arctic Oscillation is back — with a vengeanceIncredibly enough, snow is forecast for Thursday night and Friday during the day, stretching all the way from Dallas across the Deep South to Tallahassee in the Florida Panhandle.
If this storm develops as forecast, all 50 states could have some snow cover as of Friday, according to Patrick Marsh of the National Severe Storms Laboratory, quoted in USA Today.
Just as strange, temperatures in parts of Greenland are reaching 40 degrees — and in one spot even 50. There’s also a 30 percent chance of rain — not snow — forecast for the southeastern part of the island. (To check the weather in various locations in Greenland, see this Weather Underground page.)
I had to dig around to find a better chart. Here it is with the predictions for the next week or so:

The period we are going through may be one of the longest deepest periods seen since 1950. (I wonder if there were big East Coast snow storms in 1969?)
A quick Google search finds that the Lindsay Storm shut down New York for 3 days in February 1969. Called the Lindsay storm because the Mayor , John Lindsay, did such a poor job overseeing snow removal.
