Seems like we'll get a show over there! Strong destabilisation will happen by midday and a sfc low in the Laurentian will increase directionnal shear along the St-Lawrence Valley East of Montreal. My concern right now if that strong forcing will lead to linear system and this may prevent tornado threat.

I'll be chasing today and best chance for a tube will be soon after initiation. Hope I can pinpoint my target on time since this will be an early show.

Well a funnel cloud was spotted in Boucherville and hail the size of golf balls fell in Beloil according to some people. The news are reporting 8 trucks flipped over on the Montreal bridge causing 2 injured.

Interesting wording in this summary out of Quebec.

Summary of significant weather events
For the province of Québec issued by Environment Canada Montréal

...Severe weather over the province of Québec...

The passage of a strong thunderstorms line in the afternoon over
southern Québec has produced several severe weather events. Hail,
downpours, gusts of wind of more than 90 km/h, real hell. The
presence of a very warm and humid air mass over the province of
Québec has contributed to the development of strong thunderstorms. In
the morning, warnings of severe thunderstorms were issued by the
Environment Canada weather forecasts centre.

Here is a first summary of the severe weather events observed until
until 05:00 PM.


Locality......Event(S)......... Hour (lcl)

Elgin gust of 90 km/h 01:30 PM EDT
St-Hubert gust of 111 km/h 02:24 PM EDT

Those storms are now in central/western Maine. Hopefully some will make it this far later this evening.

Real hell? First time I see that written in a statement. All I can say is that we got hammered! We were on the roof of the shopping centre looking at the storm coming in and wow just wow. The sky was so dark and had a greenish tint. I snapped a few pictures. When the wind and rain began it really was crazy. The water was coming up from the floor drains in the food court. A bit of damage to the doors of the centre as well. Very intense.

Looks like it's not done for here yet either. Radar still shows a strong line coming in from the East.

Why are there no watches, warnings even in NB, there's a mean bow echo moving on in... Winds prob 100 km/h...I wonder if EC is asleep or something?

We chased a supercell ahead of the line near Beloeil and saw 2 rotating wall clouds, each produced brief funnel clouds. Then we were soon catched by the line of storm and had to punch. By then the whole chase was over. Something like 45 minutes chase and everything was done.

Any pics? I was watching that sup... it had a defined hook and slight rotation on GR2.

'Spectacular' storm in Montreal sends transport trucks toppling
INGRID PERITZ

June 11, 2008

MONTREAL -- Large transport trucks toppled like plastic toys on a major Montreal commuter bridge yesterday as a brief but brutal storm whipped through the city and caused widespread damage.

The Champlain Bridge linking Montreal and the South Shore was shut to traffic for hours.

Eyewitnesses say the afternoon sky turned black and the waters of the St. Lawrence River roiled violently as winds reaching 120 kilometres an hour tipped seven rigs onto their sides.

One truck fell onto the bridge guardrail high above the St. Lawrence.

No one was seriously hurt, but drivers were left shaken.

"It was very spectacular and very scary," trucker Réjean Chapdelaine told Radio-Canada. "The wind was pushing, and my truck started to dance on the road, lifting from side to side, swinging back and forth."

The afternoon storm punctuated an energy-sapping heat wave that has gripped Montreal since the weekend. With relief from the heat came a violent burst of wind, rain and lightning.

The South Shore and various parts of Montreal were hit hard, with century-old trees being uprooted and lawns left littered with patio furniture and hail the size of table-tennis balls.

The storm also delayed flights at Trudeau International Airport and cut power to more than a quarter of a million Hydro-Québec customers provincewide.

Environment Canada had issued a severe weather warning for the Montreal region.

"Weather conditions are favourable to the development of severe thunderstorms. Some of them could produce large hailstones - high winds - heavy rain and intense lightning," the federal agency said.

René Héroux of Environment Canada said winds on the Champlain Bridge were nearly hurricane force.

"The whole southern part of the province had a severe weather outbreak," Mr. Héroux said.

He described the phenomenon that struck the Champlain Bridge as a "microburst" because it combined very high winds over a concentrated area.
