Powerball Posted December 10, 2013 Share Posted December 10, 2013 I'd be in heaven. Don't get me wrong, I love quick hitters too that drop big accumulations in 6-8 hour timeframes, but I'd much rather have 6 inches spread out over 2 days than 8 inches in 4 or 5 hours and the fun is all over. Different strokes for different folks I guess. Long duration light/moderate snowfalls just don't get my adrenaline running like, say, what happened in Philadelphia on Sunday.

Powerball Posted December 10, 2013 Share Posted December 10, 2013 There are two things I'm not seeing that we would typically see if the big snowstorm threat was real. 1. The DGEX remains flat/unphased (whereas typically we would see super amped/phased weenie runs by now). 2. None of the GFS ensembles (except 1 or 2) show anything close to what the GFS OP and GGEM show. Bonus: We haven't seen a GGEM run that bombs this out to 988mb over Lake Huron.

A-L-E-K Posted December 10, 2013 Share Posted December 10, 2013 bomb chances are pretty much zero, especially for the western portion of the sub. As long as the euro maintains a minor event it will be worth watching but my interest is certainly not what it was. Link to comment Share on other sites More sharing options...
Gilbertfly Posted December 10, 2013 Share Posted December 10, 2013 It will also be interesting to see how fast/strong the replacement ULL develops off the SW coast after our's comes ashore....this could play a role in added moisture feed from the pacific it appears Link to comment Share on other sites More sharing options...

WestCoaster Posted December 10, 2013 Share Posted December 10, 2013 Damn, you can really see the LES potential off Lk Ontario. Oh my gosh. That looks amazing for Toronto. Wow. Has Toronto ever had a London,ON-esque LES dump? Link to comment Share on other sites More sharing options...

snowstormcanuck Posted December 10, 2013 Share Posted December 10, 2013 Oh my gosh. That looks amazing for Toronto. Wow. Has Toronto ever had a London,ON-esque LES dump? Not in my lifetime that I recall. The closest would have been January 26-27, 2004 when there was a narrow strip of 18"+ from about Humber Bay-South Etobicoke-South Mississauga-East Oakville. Amounts really dropped off north and south of that stripe. Pearson had 13", downtown had 11" and by the time you got up to Markham it was <6".

Gilbertfly Posted December 10, 2013 Share Posted December 10, 2013 yeah, that's going to jump around a lot...timing issues seem pretty major at this point. yeah...will be interested to see when euro moves the ULL onshore in the SW vs. the GFS.....history says it should be a little slower than the GFS...but that doesn't really help resolve anything Link to comment Share on other sites More sharing options...

Gilbertfly Posted December 10, 2013 Share Posted December 10, 2013 Over/under 6.2" total snowfall with clipper and this system at ORD? over (2.5 for clipper 8+ for this system) EDIT: I will add this before people think I am nuts.... either way you slice it...this system has a fairly decent setup for prolonged lake enhancement...whether it ends up being a little better phase then depicted now (which I think will happen) or its a messy phase/transfer situation Link to comment Share on other sites More sharing options...
harrisale Posted December 10, 2013 Share Posted December 10, 2013 Temps look to be quite cold with this system as well, would expect to see some pretty good ratios. -10C (14F) at the surface for YYZ during the height of the event. Fluffy snow would likely blow around and drift pretty well too. Too early to get excited but the support is growing for a decent event here.

Ottawa Blizzard Posted December 10, 2013 Share Posted December 10, 2013 bastardi is not on board I'm mostly joking, he's a weenie I hear ya brother...he's real smart, but biases can get in the way frequently Bastardi actually isn't doing too bad this year.

wisconsinwx Posted December 10, 2013 Share Posted December 10, 2013 southern/southeast WI look good this run with the long duration fetch off the lake + synoptic snows. Models have been showing this scenario pretty consistently but hard to believe how well we can do with not a very strong low in an unfavorable location under normal circumstances.

Fluffy snow would likely blow around and drift pretty well too. Too early to get excited but the support is growing for a decent event here. I'm cautiously optimistic about this event. Regardless, this December is a definite improvement over the past two in Toronto, and southern Ontario in general, at least in terms of temperature.

A-L-E-K Posted December 10, 2013 Share Posted December 10, 2013 Over/under 6.2" total snowfall with clipper and this system at ORD? tough call...assuming 3" with the clipper and a potentially generous 3" (final call) with this system, I'll go under.

A-L-E-K Posted December 10, 2013 Share Posted December 10, 2013 over (2.5 for clipper 8+ for this system) EDIT: I will add this before people think I am nuts.... either way you slice it...this system has a fairly decent setup for prolonged lake enhancement...whether it ends up being a little better phase then depicted now (which I think will happen) or its a messy phase/transfer situation It's way too early to hash out lake details but as modeled, it's a very minor factor for NE IL and yeah, going in for 8+ is a stretch but good luck.
