This one didn't hit my radar, so to speak:

3:16 PM EST Tuesday 14 February 2017
Snow squall watch in effect

Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.

Snow squalls are expected to develop Wednesday.

Snow squalls and blowing snow will begin Wednesday morning and are expected to diminish by Thursday morning. Snowfall amounts of 15 cm per 12 hours are possible.

Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Visibility may be significantly and suddenly reduced to near zero. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ec.cpio-tempetes-ospc-storms.ec@canada.ca or tweet reports to #ONStorm.

I was going to start a thread on this today you beat me to it. Here's my map which I made this morning for the outbreak. Primary wind looks to be NNW so the Goderich to London corridor is at highest risk, as well as Collingwood to Angus/Borden area.

Some areas could see up to 20cm by Thursday morning.

LOL I didn't see a thread, so I thought I'd start it. I've been busy with work and a non-profit I work with, so I haven't had a chance to look at the models in a couple of days. Nice map! Thanks for posting!

The last snow event before the spring thaw comes in for the weekend and next week. Then we reset back to 0CM and hope for a couple more storms in the last few days of February and into early March before winter is history. Im just hoping we can break the 155cm mark to finally claim an above normal season here snowfall wise.

We still have the first half of March. I'm hoping we can edge out a couple of more good snow events here and maybe hold onto them for bit just to boost our totals and have some more snow to enjoy before the season ends.

With the possibility of El Nino returning next year I'm not nearly as optimistic about next season.

Yes March historically has had some great storms here. They usually occur in the first 10 days of the month. After that, there have been documented snowfalls but usually nothing epic (over 25cm). So I'm holding onto some hope that we will get our first real blizzard this winter.

Although, IMO this lake effect event will sneak up on many. I can see some solid bands developing Wednesday and continuing into Thursday morning. Reports of 15-20cm will occur, locally 25cm.

Yup, first half of March has been ripe for solid storms in the past. It's at the tail end of the season where we can still manage solid snowfalls that have the potential to stick around if temps are cold enough as well.

Hoping for a decent snowfall next month and maybe some additional snow into April to boost our totals a bit tongue.gif

Think the action will occur later on. Nothing epic as the band moves westward quickly, but maybe 10-15 in favoured areas:

Any sustained LES will begin around the 5-7pm hour today and continue into Thursday morning. It's not a huge outbreak by any means but the hardest hit locales could pick up 20cm.

^ Just got home from work , roads are snow covered north of #89 and Airport Rd. No real heavy accumulation in this area from that G Bay squall , seemed to dissipate rapidly once it hit the escarpment. Total of 7cm down . Actually looks like another streamer is forming in the Angus to Alliston area at the moment . Bring it on !!!
