-39F in upstate New York… An impressive 10-day period of ‘sustained’ deep cold!

It hit -41 in Minnesota yesterday and nearly reached that again in upstate New York this morning.

Think it was cold Christmas eve through Boxing day, think again as it looks like New Years eve through Jan 7 is even deeper cold.

We have a clipper diving SSE now, once this exits, the floodgates open.

Duration of this cold is likely to become noteworthy!

Impressive to see GFS pushing 498 thicknesses almost down to NYC on Jan 1.
