Severe weather outbreak - June 6-8 - Plains to Northeast

[CrazyC83]

I just missed two of the cells - one stayed just south, another fizzled.

Looks like a 1,500 mile long serial derecho?

Definately looking that way . . . new WW for eastern NY, and the cells are starting to form a line from upstate NY down through central VA and intermittently into southern NC . . . quite the derecho.

LSRs already greatly exceeding the numbers from yesterday

wow?! There were 124mph wind gusts in Niagra and Erie counties earlier?

From the SPC:

Time Speed Location County State Lat Lon Comments
2144 124 BARKER NIAGARA NY 4333 7855 (BUF)
2138 124 HAMBURG ERIE NY 4272 7883 (BUF)

That's amazing!

That...can't be right. The highest wind gust I've ever heard of in any thunderstorm system is 135 mph. We need pics from the area affected!

The storms that occurred in Ontario were very impressive and starts to rank up there with the July.17 2006 and August.2 2006 events. There was high wind events pretty much everywhere in the province except maybe the far North-west parts of Ontario. I saw quite a few videos on TWN showing funnel clouds around but no confirmed tornadoes by EC yet. I think over 122,000 have lost power and will have it back on by Saturday.

There were tornado warnings issued for Hamilton and Branford Ontario at around 4:20 pm or later. When I checked the radar, the intense line of storms hadn't even reached those areas yet! Here are some radar pics:





Incredible. I also have enough radar images to show that two squall lines met up in Barrie and joined. There was also purple on the radar right on top of London Ontario (most likely got a hailstorm).

That has to be one of the longest serial derechos ever. It produced significant damage along a 1,200 mile stretch from central Quebec (with the low) all the way to Tennesee and the line producing it extended south to Texas making it about 1,800 miles long!

We had a bunch of thunder and lightning but no rain.

We had a bunch of thunder and lightning but no rain.

The funny thing was it was the exact oppisite here. I heard hardly any thunder and saw no lightning but the winds were quite strong and lots of rain. This was not the case everywhere though (some squall lines were way stronger and brought everything).

There should be a Wikipedia article made for this event because of how widespread the choas was.

Well at least something happened somewhere. LOL all the talk around here this weekend was alllll the hype everywhere (news stations too) and we didn't even get a sprinkle (though north of chicago by the state line did get hit by some severe thunderstorms).

What an interesting system to follow. While we have come a long way in understanding the weather, it makes us realise we have so much to learn still (which I think is actually exciting to look forward to).

Yes, severe wx is one of the most challenging types of wx to forecast. As someone whimsically put it (in another board), "it's just convection".
