The warm air surging up the East Coast on Christmas Eve will prove nothing short of historic. Dozens of records will fall, some by very large margins.
Temperatures at or above 70 degrees will span from Florida all the way into southern New England covering some 1,200 miles and 20 percent of the Lower 48.
In many places in the East, temperatures will run some 30-40 degrees above normal.
The warmth in a few locations will be so anomalous that low temperatures will challenge existing records highs.
The map below shows all of the locations where records highs are in jeopardy, from Florida to Maine.
Here are a few highlights:
* The temperature in Buffalo is forecast to be near 60 degrees at midnight, the start of Christmas Eve, breaking its record high for the date in the middle of the night.

* Boston is also forecast to break its record high the moment the clock strikes midnight.
If the GFS is right, we'll break Christmas Eve's record high (61) as soon as the clock strikes midnight. Ridiculous. pic.twitter.com/JDNaKKWLIL

* The forecast low in New York City (Central Park) on Christmas Eve in the low 60s would match its record high of 63 from 1996. By the afternoon, it should reach the low 70s, shattering the record by ten degrees.
* Washington, D.C. may challenge records highs not only Christmas Eve, but also on Christmas Day, and Dec. 27.
* Much of Florida will see record-breaking temperatures well into the 80s.

The anomalous warmth forecast Christmas Eve fits right into a December that will rank as warmest on record for much of the northeastern U.S. into the Mid-Atlantic.

The warmth is indirectly linked to the very strong El Nino event in which heat from abnormally warm waters in the tropical Pacific is infused into weather patterns over North America. In this case, the flow of air around high pressure centered over Bermuda is pumping deep tropical air straight up the East Coast.
The El Nino event along with sustained climate warming from greenhouse gas emissions will result in 2015 becoming the warmest on record globally by a large margin.
