FRIDAY DEC 16 AFTERNOON ABOUT DEC 22-23 POSSIBLE EAST COAST WINTER STORM

First off   HAPPY BATTLE OF THE BULGE DAY   !!     16  DEC  1944   more on this   huge  WEATHER pivotal event  over   next several days

12z FRI op-Euro & 12z FRI op-CMC did huge 180 degree flip but the 12z op GFS held course.
WHY? /1 see image

if you recall Last winter European was stunningly wrong & inconsistent with a LOT of false signals. The CMC this far our for East coast winter storms is like trump trading cards= worthless crap.  As I have stated many times the KEY is **ALWAYS ** the 50/ 50 Low. It is great to have a Green land block/ – NAO but having that AND a 50/ 50 Low in southeast Canada is IDEAL. I believe that IS still going to occur given the massive block in Greenland.  I dont see how there will NOT be a large closed 500 Low in southeast in Canada or Labrador early next week.  Therefore at this time I do not consider the12z Fri operational European in the Canadian models to be Valid. Of course I could be wrong.

Patterns / wave physics over models!
