JOESTRADAMUS JUST LOOKED AT THE NEW GFS,
 
AND HE MUST SAY HE IS RATHER IMPRESSED,
 
THE MODEL IS SHOWING US SOMETHING QUITE BOLD
 
IT IS MUCH FURTHER EAST WITH AIR THAT IS COLD
 
SHOULD THESE TRENDS CONTINUE TONIGHT
 
A WHITE CHRISTMAS WE’LL HAVE BOTH BY DAY AND BY NIGHT!

Weather models last night began a colder trend to the east regarding the push of very cold air coming out of Canada and a wave of low pressure forecast to develop Christmas Eve and move up the coast with some snow for somebody. The issue up until now is that the main push of cold air was more south than east. However models were hinting at a broader jet stream pattern that would allow some of this brutally cold air to wedge eastward to our north and bleed southward.

Now comes today’s model run and we can see hints of this on the NAM model as well. The lead system that sets all this up comes on Saturday but before that we have a warm front pushing northward Thursday night into Friday which could bring a period of snow or ice for areas north and west of NYC in the Hudson Valley, Northeast Pennsylvania, Northwest New Jersey, & Connecticut. This is due to energy breaking off from the west and running out ahead of the main system that develops Friday night and Saturday in the Lower Mississippi Valley and runs to the Eastern Great Lakes. That pushes a cold front through here Saturday night (slower) with colder air coming in behind it. Today’s model run is much colder and opens up the door rather widely for the possibility of snow Christmas Day.

There is one other possibility here and that is the cold air winds up overwhelming and pushing everything further offshore in which case we just turn colder and dry and don’t see a flake at all. Obviously I need to look at things a bit deeper and we will be updating this after the European model comes out. Given the amount of liquid precipitation the model generates this would produce several inches of snow in most places if it were to pan out. Clearly the trends are colder and east.
