December Pattern Disco- 2013


Damage In Tolland

Recommended Posts

Sounds like it's standing room only on the Tobin.

We have to remember that the first snowfall over 1" across the region typically doesn't happen until that 7th (BDL) to 14th (BOS/PVD) time frame. I mean maybe Will has a case to gripe in ORH because their long term average first date for 1"+ snowfall is 11/27 (and even they had that 0.5" earlier this month).

Yeah it's always tough for snow in this area before mid December to be honest. You and I both probably remember some bad Decembers. In fact, in my mind I used to treat December snow as gravy. January and February were our months.

I don't think anything changed. As we started to go out in time since Wednesday or so, the GOA feature showed up. It's not like things just trended warmer. The weeklies even showed a SE ridge expanding north albeit weak. The 7-14 is the hopeful period. It's not a lock, but offers the best chance. Nothing is ever a lock in meteorology. I really wouldn't panic about winter or even this month. Not yet anyways.

That was my misunderstanding then. I went to the beginning of this thread and it seemed like the very start of the month was when we were expecting some good chances at wintry wx.

Guys get caught up too much in who says what in the long range.  It's all reliant mainly on models, recognition and analogs that are subject to change.

 

Was looking at this tonight.  You can REALLY see why guys are chomping at the bit already.  Recent Decembers have spoiled us.

My best December in RI was probably 1989, which I don't really remember at all. 2003 I was at college, 2008 and 2009 I was working at DVN. SE gales FTW!

And keep in mind that most often the snow was in the second half of December in those stats.

It's all going pretty much like one would expect for a non Nino extreme winter.  Heck it's cold. 

 

Snow for the holidays is a great thing and it's still many moons off.  I just don't want to keep seeing cold/squashed.  Had enough with cold/surpressed a few years ago.

Still no reason to panic for the month. While it may not be as favorable as next week, there are signs more ridging near and NE of Greenland tries to punch in from the northeast to keep the PV near Hudson Bay after next week. Also some signs on both models this GOA trough may try to move out towards the end of the run. With the strong zonal flow..it also may allow for weaker disturbances which is a good thing because anything amplifying would furnace us. The weaker system idea isn't a lock, but something I surmise. Anyways mid month definitely turns less favorable, but I don't see a prolonged torch. It still would keep interior and esp NNE in the game I think. Obviously this can change and personally I'm not a fan of that look at all...but it's not a December 2011 look by any means. Give it another couple of days to see what happens...models will probably warm and cool with each run.

Euro back to its senses on 00z run..Blasts the cold front thru Friday afternoon/evening.

 

You wonder though if it's too far south with the ice/snow next weekend as it keeps first wave way south of us.

 

Probably not. Nothing to really amplify this system unless the front stalls. Cold and dry FTW and then cutters?

You say favorbale next week..and then forecast cold and dry with a cutter?

lol just remember the Nov 1st panics. Happy birthday young man

6.4" of snow in November at BTV on the lake is a pretty decent little start to the winter.

At home I think I was in the 12-14" range, while JSpin was up near 18"...1500ft was 23" and 3000ft was 45".

My Nov panic worked. Aim low and be surprised. ;)

Yeah seems to be the same on the GFS...the cold noses in and pushes everything way south.

Again, there's not much wintery precip down south either, most of the training moisture is in the warm sector. Even if the boundary was north, it's still not going to bring much, the best lift is south of the fronts. Like that last system, there's just no moisture getting thrown into the cold dome from anywhere. Most of the US goes dry when these cold shots come in, then the precip starts up again once it warms a bit.

I do think we'll see at least one threat during the 7-8 day period around the 7-14th of the month. Threat being anything from snow to snow or ice--> rain.

Ahh I thought he was talking about all that over-running precip along the boundary way down south in like the Dec 7/8 time frame.

If that boundary doesn't get way south, we'd probably likely see a cutter right after in that 12/9-11 range. I could envision a SWFE in there as long as we can get some good cold to settle in next weekend following the front.

In that case, it wouldn't shock me to see it mostly dry. The euro argues for a very brief transition to sleet or snow at the tail end, but I see nothing exciting from that yet. Still a little early so maybe it changes.
