First Winter Storm Threat for New England 2011/12 - II


Baroclinic Zone

Recommended Posts

Will, 1-3" seems like a conservative call for Rindge/Monadnocks given that most models print out close to 1" QPF, with the majority falling as snow here. Are you expecting the storm to be warmer like the 12z NAM where some of the initial overrunning is lost to rain, or are you just doubting the intensity of the precipitation without a closed H7/H85 low for the entirely of the storm? The 12z NAM did close off the 850mb vort off the coast of New England, so maybe it's on to something about more of a CCB with moisture wrapping back into the cold air?

I was talking about this in my meteorology workshop, kids are very excited. I said 2-4" would be a decent guess for campus...we're often a little colder than downtown Rindge.

In model progged storms ...my philosophy is always "the bird in hand is better than two in the bush" LOL

Even if the bird in hand is a chicakdee and the ones in the bush are fat wild turkeys. ;) I concentrate on my short range chances and then worry about the dream storm in the medium range +.

I said yesterday, I'd rather have my eggs in storm 1's basket, The Euro pretty much by itself with storm 2

Well I did say some lollies to 4"+...your area would be a good spot for that. Not all of the Monadnocks are as high as you near 1300 feet. Areas in the 900-1200 feet range will obviously not do quite as well.

If we see this strong frontogenesis in the cold column continue over the next 2 model runs, then I'd probably go a little more bullish across the board for the northern hills. But when its still 60 hours out, you have to remain a bit conservative because there's a lot of things that can go wrong...33F non-sticking snow and wasting qpf on cold rain are just a couple of those things.

I'm surprised at how cold the GFS ensembles are for Thu night. Every single one is colder than the OP run at 60 hours. That's certainly some good news for getting better accumulations across most areas in SNE/CNE.

Would you consider the Thursday event rare for date?

I was just looking at those. The ensembles seemed right along the BM which may explain it, but that would be an awesome track for you...basically along the 40th parallel.

I'm busting my assistant principal about it, telling her I might be late coming into work, etc...

lol

You might be right about 2-4" there...
