Nice job Mike. Hope you're enjoying it.

La nada over here.

It was great. I can't even remember the last time a long, wide, persistent lake effect snow band set up over Waterloo Region. EC downgraded the snow squall warning to a snow squall watch but we are still having on and off LES activity. Nothing near what it was like earlier, but still accumulating about 1-1.5cm per hour.

As of 315pm I measured 4.5" snow depth. Will go back out in a bit and see where it is now. Check out London, SSC. Looks like a band is setting up. The EC forecast at 11am had a maximum of 24" for the city.

Edit, just measured an average snow depth of 5" with drifts near 2 feet.

TWN has video from Cambridge this morning of almost total whiteout conditions. http://www.theweathe...page_topstories

London Airport reporting +SN +BLSN with 1/4 vis in the last half hour.

1-2 feet expected there. The LES band has set up and become stationary right over the city of 450,000.

The heaviest bands looked they set up on the east side of the city, altho' here in the SW we picked up another couple of inches in the last 2 hours. Now we're in a lull again with just flurries with more bands back over the lake. They look multi-banded with no real heavy bands except for the one that clocked the east side for a couple hours. They probably picked up at least 4 inches as it looked to be at least 35 dbz. A wait and see approach as to where the next ones set up - if the winds come more out of the NNW the bands should swing back south and west.

Great pics and video! Had 0.3" last evening and another 0.1" overnight, wind today sublimated some of the snow, and then tonight a few heavy bands skirted through the area but we only managed some skiffs of fluff out of it, just a trace. Lots of flakes dancing in the air, but just light accums range every mile or so from just a trace to probably an inch, a pretty typical les event for SE MI.

Check the radar. For the last 2 hrs Owosso to Brighton has been getting hammered.

I have been checking the radar lol, thats why I said a few heavy bands skirted the area but just left an additional trace here. I was watching the snake-like thin bands run down, hoping it would hit me, and I did have a few more blowing snow showers, but not enough to chalk an addition tenth of an inch.

Sandwiched in between the bands, ugh. Although so much for losing the diurnal component. That band from Howell to Ann Arbor is the strongest most persistent band of this entire event in SE MI. Will be interesting to see what the Ann Arbor spotters report tomorrow.

Interesting to see how healthy those two bands have been

Yes. And the winds are still gusting. In fact, the wind today sublimated our 0.4" of snow to just skiffs in the grass with a little more on the edges. One thing we never really should complain about in metro-Detroit (esp east side) is LES. If you are right under a band you can score, otherwise a dusting is your safest bet in most LES setups (Jan-Feb 2007 notwithstanding, of course that was a synoptic nightmare). All I can say is Im really pining for some action by midmonth in line with some of the ramblings Ive heard.

two occasions where Ive scored on LES. In Feb 07 6.5" and once in Dec 08 3.5"

7 inches overnight, so it looks like about 10" total locally here in the SW part of the city. Interesting that the airport in the NE part of the city already had that much by 10 pm. I've already been out and shovelled the driveway. The radar was showing the heaviest snow on the east side of the city again this morning, so I wonder what things look like over there. I'll find out shortly as work is very near the airport. Should be a very slow morning commute.

Darn wife took the camera when she and the kids left to visit her parents on Sunday. :axe:
