When I was a kid and saw this happen I tried to calculate how high a wall would need to put up to block the warmer air from coming in off the ocean or failing that, how much liquid helium we'd need to dump into the ocean to freeze it solid.
Yep I think 4" is the point where it's okay if it flips over. I remember we had a storm in the early 90s (maybe Feb 93) with 4 inches of snow in 4 hours and then rain for 4 hours. We got 4 inches and Central Park got 6 inches because they were snow for an extra 2 hours before it changed over there. There was still enough snow left over at the end for it to look wintry here.
Anything less than 4 and it's not worth it.
It's interesting that there's 15.1 inches south of us in Delaware and 14.6 inches north of us in CT, so are these 3 systems a mix of SWFE and suppressed?
Maybe not quite as anomalous because it's February and not March? A few of those systems were quite borderline so more snow should be expected than we had that month since we're still in the middle of winter.
Don, are the Euro HIRES and EPS nao projections accurate though, they have the NAO around -2 to even -3 (EPS) by the 15th also (between the 11th and the 17th)..... the Euro AI drops it down even lower than that all the way down to -5.
Lows:EWR: -2 (1961)NYC: -3 (1881)LGA: -1 (1961)JFK: -1 (1961)
Tony was this great arctic outbreak in February 1961 just before the HECS that dumped 25.1" of snow at JFK? Their biggest snowstorm until PD2 (2003)!
Looks like primetime begins on or after February 7th and the AO bottoms out around the 15th. If we extend this outward it should become positive again by the 23rd, so we should score something by or before then.
Yeah I'd like someone to run some numbers and point out what our best 15 day period is for double digit (10"+) snowstorms, but I think it would be approximately from Feb 5 - Feb 20.
