Dec 9th Winter Threat

Kevin, if you wouldn't presume snow cover 11/15-3/15 your expectations wouldn't create such frustration. Seriously stay the course. 1993 had a huge prolonged warm period in December before the hammer. Too bad we didn't have the internet to see the meltodwns.

what was amazing about that season is that 5 day forecasts 2-3 days out had warmth warmth warmth and then all the sudden around 12/27, the hammer dropped...the rest is history

I admit I thought we were heading for something similar.

 

and now Mondays system is tanking. seems like these are trending towards fizzling out for us but they are producing pretty well in the south MW for sure.

 

Well who knows..it could still be like that down the road..or maybe 15-20".  Despite some frustrations and I do understand why....I still think this month holds promise based on how the pattern looks and previous similar setups.

It should also be noted, this is not the only storm chance in this pattern....you had just started posting back then, but you might remember the freakouts after the ice storm in 2008 (which of course didn't hit everyone here) when we had that torch and the 12/19 event hadn't appeared on the models yet except as a cutter in clown range on the Euro.

 

We had a day or two of meltdowns. Its early still...and this 12/9 system may still be pretty wintry.

This is exactly what I was trying to convey....even were 2007 and 2008 to walk through that door, it wouldn't be for another week or two. Additionally, favorable gradient patterns can evolve from rather underwhelming modeled patterns, and vice versa because they aren't representative of our prototypical snow patterns, and are thus rife with synoptic flaws.

 

Gradient patterns are never pretty, and you're always "living on the edge", so to speak.

the good thing is that the relaxation or warmth concerns seem to have fizzled a bit lately?

Well we do lose the dateline ridging..the mega amplitude anyways..but there is another ridge developing in the EPAC. This may try to teleconnect to a trough in the Plains and some SE ridging, but it also helps keep the possibility of more cold dumping down from Canada. We also may see the MJO move into more favorable phases towards Christmas, but we all know how bad MJO forecasting can be.

I was just hoping for a little snowcover next week and we've lost any shot at that

I'm not sure of that but like others I normally don't get antsy until mid December. So much work to do before everyone puts the snooze button on from 12/20-1/5 roughly that there's a plus to going about my business unimpeded. Don't get me wrong, I would thrill on some snow but so much stuff going on I can deal without it for a other week or 2. Weekend of the 20th my wife and I are heading to our favorite pre child b&b in southern VT. I'm hoping its wintry then.

Sne snow climo on the cp tends to be more dissapointing then rewarding. We remember the good years and try to fantasize back on them, then we end up just deluding ourselves into remembering this place as snowier than it really is, The bottom line is sne winters esp near coastal plain are chalk full of despair and suffering , so cheer up. Anyone hoping for wall to wall anything is placing a horrible bet w their future emotions....unless of course your willing to get away to NNE where it is likely to "look like winter" at least most weekends from dec to march :) ahhhh the whites and greens at elevation, a snow /winter lovers heaven

People can sometimes have unrealistic expectations, but climo says most of SNE gets less than 50 inches of snow and has snow cover for less than 60 days a year.

As maddening as this pattern of arctic chill, and cutters interspersed has been, one must not lose sight of the fact that we are still in the first half of December.....which climatologically speaking, blows for snow around here:

Snowfall through 12/12/07 imby....5"     (Monthly total- 33.5")

Snowfall through 12/16/08....T            (Monthly total- 31")

Snowfall through 12/19/10....T               (Monthly total- 15")

 

 

Wow, those are some nice recoveries in 07 and 08!

EVALUATING LIFT...THERE APPEARS LITTLE IN THE WAY OF JET DYNAMICS
/RIGHT-EXIT REGION OF THE UPPER-LEVEL JET/ AND DEEP-LAYER ASCENT
/WEAK DISTURBANCE ALOFT AND NO JET COUPLING WITH SURFACE FEATURES/.
IT APPEARS MUCH OF THE FORCING IS PER ISENTROPIC LIFT AND LOW- TO
MID-LEVEL CONVERGENCE AGAINST THE LINGERING COLD AIR DOME ASSOCIATED
WITH THE DEPARTING HIGH PRESSURE.

A couple of years with very early season snows moved everyone's timeframes up. We are really just heading into winter now and everyone's patience is shot.

Hopefully the 9th works out

 

I would argue that this year the bigger thing fueling any unrest is that the cold air has been in New England, but it still hasn't had a widespread snow yet.  We had a solidly below normal November, and appear to have more arctic chill moving in.  It just goes to show that cold anomalies won't bring the snow if the pattern isn't there. 

 

Its not often we'll get a -2F to -4F type November and continuing into early December without some sort of widespread early season snow.  Its like folks won't usually expect a widespread winter threat prior to Dec 7 or Dec 14, but if we are hammering in cold anomalies that perspective changes some.
