he has used that line for the last 95 east coast snowstorms

definitely one of his favorites. you ever noticed he always picks on the gfs when it's not showing a storm and talks about it's usual errors. Yet all he says about the euro, (which also isn't showing a storm), is "the euro hasn't come around yet". lol

How about, "I got the meteorology right but the weather wrong!":arrowhead:

And now we wait to see how much of an outlier the operational GFS is with its ensembles. The gap has been growing each cycle.

And that gap is the Nogaps... another great hit... probably about 25mm or so. Hasnt budged from this solution since it came into range Monday.

I really am astonished at how consistent the NOGAPS has been...I mean granted, it is almost certainly going to be consistently WRONG, but the startling metronome-like regularity with which it has been spitting out essentially the exact same solution for literally DAYS now has me in awe.

Maybe it broke and someone in Annapolis is just releasing the same forecast from 4 days ago ;-)

lol, the NOGAPS is such crap...but i like that its trying to make a name for itself. I'm pulling for ya NOGAPS

I remember back in 98 and 99 at PSU we would actually look at the NOGAPS a lot. Not because it was any good but there wasn't that much guidance past day 3 back then. AVN only went to 72 hours. MRF went to 10 days but it was only run once a day. Same with Euro and it was impossible to get much on it until 7pm almost. ETA and NGM went to 48 hours. I remember Dr. Neese yelling at us one time for analyzing a day 5 storm on the NOGAPS in the weather station. lol It used to flip around crazy from one run to the next. I never remember it having one solution locked in like this over and over.

I wonder if there is something in its progressive bias that would cause this solution. Perhaps it moving the western energy in faster and allowing a better phase with the coastal.

FWIW... NOGAPS is a bit warm in the 850 department at 90.... then crashes at 96

it will have to be, if we want heavy precip we need good moisture advection off the atlantic from the coastal, but with that also comes WAA at some levels... to get the big win you have to dance with the devil when things are not lined up perfectly like last year.
