Ottawa Blizzard Posted January 26, 2019 Share Posted January 26, 2019 10 hours ago, Roger Smith said: Whatever the track, this low will be interacting with two very cold air masses ahead and following it in. It may not have a very well-defined warm sector at all, and could become one of those circular blizzards of days past. There was a storm like this on Jan 30-31, 1971 if you want to see an analogue. Snowfalls of 4-8" along the track and 10-15" lake enhanced could be expected. Green Bay might get 15-30 inches of snow out of this as a lake effect dynamic persists ahead of the low and behind it. The u.p. of Michigan will have life-threatening blizzard conditions with -15 air temps and -40 wind chills with S+ from still-unfrozen Lake Superior (we'll see how long that lasts next week). Would say 6-9" most likely for Chicago, 9-15" Milwaukee, 5-10" range in s MI and sw ON to 20" locally in lake effect squalls. Was commenting in the temp thread that the following air mass is record cold already up in the central arctic, -56 F at Shepherd Bay, NU. Roger, what are you thinking for Toronto? 4-6"?

I know that's the forecast, but I don't see that happening with the SLP track further north. we're looking at precipitation type issues fairly close to us.

With a track north of us, we'll be lucky to get half that. The northern models are quickly diving the PV southward and phasing, causing the slp to curl northward. EURO/UKIE are slower with that feature, and thus more favourable to us (although they've been inching north too). I'd say 3-4" for us right now, and hope to god it doesn't trend any further north.

I would not be surprised to see the precip/snow wrap all the way back around the low center. To me, despite it's northerly track it still will have the ability to put some snow down fairly far south of the main storm on the arctic front. Seen this before. Quick 2-4" hit with strong winds,blowing snow, and rapidly falling temps. I'm certainly not a met., but do rely on my memory and history of prior events when I see certain set ups. 2 Link to comment Share on other sites More sharing options...

Wouldn’t completely count out a shift south enough to bring some heavier snows (maybe 6-9”) south 50 miles or so. Especially with what happened with the last system.

ILSNOW Posted January 26, 2019 Share Posted January 26, 2019 And another thing to consider while we have the NAM and the GFS with the low into Southern Wisc we have the Euro (granted alone) into northern IL. who do we trust at this range? Link to comment Share on other sites More sharing options...
whoosh Posted January 26, 2019 Share Posted January 26, 2019 and a short while later, as that northern polar piece bears down (tricky timing) the 700mb temp/wind panel: still working the turn. 1 Link to comment Share on other sites More sharing options...

Probably not the Euro with clippers; if this was a Panhandle Hook I might think differently. I personally wouldn't mind the Euro to win this one, but I think it's unlikely. 1 Link to comment Share on other sites More sharing options...
Powerball Posted January 26, 2019 Share Posted January 26, 2019 It may not be much of a consolation, but FWIW, even with the northern track progged, it still looks be to cold enough for the precip to be all snow for you guys ahead of the front. It could be a decent thumping too (quick 3-5"), as the models are showing some decent mid-level lapse rates. 2 Link to comment Share on other sites More sharing options...

Is it one of these deals where the faster the clipper is, the less likely a quicker/sharper turn east?

Do the laws of physics work that way here I am illiterate in the mathematics of fluid dynamics, but don't confuse the 500mb shortwave with the lower level clipper. 1 Link to comment Share on other sites More sharing options...
Geoboy645 Posted January 26, 2019 Share Posted January 26, 2019 Well MKX is saying 7-11" of snow here. If that comes to fruition then i'm going to have a 20" snowpack before Siberia hits. Link to comment Share on other sites More sharing options...
