That convection was associated with the ULL. As the ULL moves ne, it facilitated development near the Delmarva coast. This low didn't come much closer than we thought, but I think the ULL came a little more nw and also..we always see better banding to the nw..sometimes way nw of the max modeled qpf. I like to look at the mid level features to determine it, and the track of the mid level lows was classic with this one.

Usually, lots of deep convection down south over the GOM is what can pump up the downstream ridge via latent heat release. This increase in the sharpness of the ridge causes the low to move closer to the coast.

The convection is a result of instability, but convection itself doesn't cause instability directly.

You could really see that on radar last night... just really blossoming nw when the overall motion looked east

I hope Will, etc saved those loops

One has to wonder how far we can go with this pattern. We are seriously locked in!

Jerry, glad to see you got slammed. Only 4.5" here but the mega-band was intense. Leaving now for MRG for a day of skiing the steep and deep. More snow and intense cold in our near future, enjoy!!! Big Winter incoming. Big Big Winter.

Thanks, much appreciated.

I think this storm reinforced one of the lessons that Will and others preach - that if you get a 500 mb, 700 mb and 850 mb closed low tracking relatively close to the south or southeast of us ... good things will happen regardless of what the model outputs say. Not always will it deliver but if you had to make a bet it's usually a good bet that it'll deliver.

Snow is over here..about ten inches here on the Springfield/Easl Longmeadow line with the back yard depths a solid two feet. There was a little compaction on the older powder snow from the other recent events.. I am curious to know how areas just to the nw did.

while we did not have thundersnow or rates like nyc or areas just e/se of here had we did legit have rates for awhile in the 2-3 in/hr range.

season total 48.7 inches of which 43.1 inches fell this month. We are now at seasonal norm for this area and it is 1/27/11....not bad :)

I doesn't always deliver, but I bet 8.5 out of 10 times it will.

JUst woke up from 5 hours of sleep and all I can say is WOW.

Measured about 12.3" sf here. I must have missed some sick sf rates. Going to go back and read the thread now.

Year total up over 62" and snow depth is 24-30", rediculous.

Oh yeah, its still snowing.

Great winter. We will pay for it in June though

16-18 new Still snowing, drifts to four feet. Absolutely buried probably most snow I have seen on the ground. Bob Maxson just said Epic he should have said La Epic 11 yea Bob 16-18 on top of the 3 25 gave me 19-21 yesterday like you said about Killingly. Unreal just buried, depths are near 40 unreal just unreal. I got a fiver per hour sick just sick.
