Can we salvage a White Christmas in SNE?


Damage In Tolland

Recommended Posts

You don't want it south...I think he was trying to say the trough or shortwave was digging a bit more. I suspect you'll probably get some snow out of thisin southern ME when verification time comes calling. The GFS has been a southern outlier the past 12-24 hours or so. The foreign model guidance has definitely been more amped.

Thanks. That's what I was thinking/hoping. Hope everyone in NE gets at least a little white from this.

It's a rare day that the GFS isn't suppressed in this time frame.

I fully expect the GFS to go suppressed and OTS with the 27/28 event on this weekend's runs, only to bring it back by Tuesday.

Solid warmup for us on the GFS followed by the potential big one later on.

You can really see how were threading the needle with the 27th storm. The block, PV lobe, and vort all line up perfectly for a storm on the coast, and even then its still borderline. As long as those three stay relatively the same, we should be ok, but I fear that a slight shift in the block or the lobe will change allow the vort to cut inland

FWIW NAM and SREF are both very suppressed.

The amped solutions are somewhat strange because of whats going on in SE Canada and the fact the vort at 500mb sort of just amplifies on its own without a phase into the Canada vort. You would expect dampening of the wave in these scenarios most of the time, not strengthening as they come east across the OH Valley.

At 5+ days it's highly likely we'll see significant shifts in the 100+ mile range as we approach. I agree it's a very tight window as currently modeled and truth be told at 5-6 days it's highly unlikely what we're seeing modeled is the "final" outcome as many have said. We're looking at the near perfect solution right now, quite possible it ends up booted further east or that it cuts earlier and ends up into PA etc. JMHO.

I am only 27, when was the last time we saw snow on Christmas Eve night/ Christmas morning. I remember light snow falling around midnight on Christmas when I was young about 8 or 9 years old..

It was likely different for you, but down here in Central NJ in 2002 we had snow xmas eve night to kick off that storm, about 2" accumulated before changing to rain after i had gone to sleep...it was all washed away by xmas morning and raining in the 40s, but I'll count that. It flipped back to snow in the afternoon and we received another 3-4" by xmas night. Great memory that storm was.

We had a half inch during one of the Christmas mornings in the mid 90's. I believe it was 95.
