|Warm Christmas 1982|
It's not every year that we receive snow or have snow on the ground on Christmas Day. The chances historically are around 40% which isn't great.
Back on December 8th in my post HERE I went into detail on the many forecast elements. Most were showing an active storm track with period of milder air. There was ONE we were watching closely as a driver toward a COLDER and snowy solution: The GREENLAND BLOCK!
Here is the pattern showing the Greenland Block back on December 11th. See the warmer colors near Greenland and the North Atlantic?
