I was expecting your wrath several times tonight so no harm, no foul. Trying to be positive now, the 18Z GFS is better than the frying pan pattern at 12Z but is still a rain parade with a 70's day so ground truth has not changed. Maybe in 6 hours.
Today's GFS has 70's at MDT (extrapolated from 18Z panel) which was the backing for my extreme comment. The real reason today's GFS is so bad, to me, is the lack of cold air anywhere in the Eastern US or Canada. It's an ugly look.
A drastic change from 0Z. Models are jumping all over. A colder solution for early next week but outside of Boston, a dry solution. Basically a clipper flying by to the north.
Its at least below freezing again. Dec is going to start off with a healthy positive departure per the Euro. The Canderson +8 departure would be in play on the GFS.
I dunno, I am 0-1 today. I will see if I have time. The part of the GFS that was bad is outside the Euro's range. CMC took away the 9th snowstorm and replaced it with a mix storm on the 8th. Sloppy and not real cold.
As in "Blizz is going to go off because there are highs in the 70's (near 80) and lows in the 50's"? Pitt is 66 degrees at 7AM on the 13th. Too astonishing to not mention, knowing it will change.
On the prior run, the Northern Stream Vort was not as pronounced allowing the Southern Stream Vort to to have a more West to East Trajectory. Stronger Vort on 12Z tugs the Southern Stream up.
Regardless if the timing works out for the 5-7th storm, as long as the maps keeping showing this look it will be interesting to watch every 6 hours. 12Z GFS phases them much too early for us as of today, but cannot quibble with timing this far out.
