If we're gonna have a Greenland block, better now and December, instead of in spring
I totally agree! In fact we had early big blocking in Nov-Dec 2010 and we all know what happened then. (well, not all of us knows, lol) Boxing Day Blizzard followed by 3 more big snowstorms. 64" of snow within 4 weeks here Dec 26-Jan 27 Lets repeat!
7:40-11:40am loop. We're getting Lake Ontario Effect clouds down here but check out off Lake Huron, purely a northerly flow and interesting off Lake Michigan that band is moving SouthWest hence the Chicago snow squalls
Unlike some previous arctic blasts, no lake effect clouds reached here; all clear
I think I see why.
this is the wind flow at 4000'.. Looks like your getting it from the tip of Lake Ontario, not even, but the clouds are evaporating before reaching there but since I'm getting it from Central part of the lake its more moist and reaching here but still mostly sunny day here
Watch what happens tomorrow for you
Winds at the mid levels turn from the North so no Lake Effect clouds this time for you.
As of 11am this morning the Arctic front has moved off the MD, NJ, NY, and New England coast.
And High Pressure is moving in so winds will relax tomorrow
Looks like Toronto changed to snow past couple hours. Not sure how much they're getting but looks cold and snowy behind this front.
Looks like they barely got any in Toronto. Maybe just a few flurries.
Areas to the north of Toronto barely an hour away like Barrie got amounts that were shovellable though. But that's a classic snow belt area.
Here in Ottawa-Gatineau we got heavy flurries for maybe 30-60 minutes when the cold front went through last night. Some of it settled on the grass but either sank in or was blown away by the wind. There was barely any visible snow left this morning.
Puddles were all iced over though.
Bright sunshine and cold with strong winds since I got up this morning.
-7C or 20F at lunch time with -15C or 5F wind chill.
Not buying the PNA not being positive, I think there will be some ridging out west.

So Yes, a Positive PNA = Western Ridge but it is shown when the ridge is more west than central U.S and peaking up to Canada.. More like Pacific/Western U.S/Canada..
It's also when the upper height is above normal in the West (not central).
