I saw around 8 to 12 individual thunderstorms, drove through at least five. 8-12 lollis, not bad

The 30 c/g strikes in 10 min near I-93 in Wilmington was actually the best part....no power in Wilmington throughout town when I was driving through, yet they missed storm. :D

It was constant thunder for about 5 minutes straight... sounded like a jet.... never heard anything like that before.

6/95 and 8/2000 . only times I recall "constant thunder" or what is excessive c/g lightning living in that area, in 25 years. today was sort of like 6/20/95.

any reports at the station of funnel sightings?

I didn't call in what I saw in North Haven mainly because it was very brief and I thought it had little chance of touching down, the updraft base it was under was already falling apart. But also to be honest I can't absolutely be certain there really was strong rotation in it, I wasn't all that close to it. I can tell you for sure it looked and acted like a funnel, and I've seen my share. It had that classic laminar shape, it was definitely not an outflow feature, and there was definitely at least weak rotation in both the wall cloud-like lowering it was under and the parent updraft as a whole (radar confirms this). Frankly I'm surprised no one else reported it, it was way more funnel-like then many that do get reported. It didn't last long at all, though, so maybe I was the only one who noticed it. I'd say the feature in its clearly-recognizable-as-a-funnel phase lasted only about a minute or two.

Absolutely fascinating. Wish we had a pic!

Man the media went nuts here today. The anchors were clueless calling shelf clouds wall clouds and saying tornado warnings were issued for the state lol. That always happens when non mets talk weather.

I wish I was in a whale watch boat in the harbor today. That cell was epic. I wonder if there was a spout well offshore.

What would you call that pic taken near Logan?

That radar signature was pretty impressive over Boston harbor, would love to see a waterspout with the skyline in the background...

For those interested in the mechanics that over-produced today in the Boston metro / Eastern Mass, here's an interesting article on the interaction of a seabreeze convergence line and a southward moving outflow boundary to overcome insufficient shear and produce a tornado:

http://www.nwas.org/ej/2005-EJ6/

Excerpt:

"However, in special circumstances like those on 7 August 2003, the combination of outflow boundaries, sea breeze convergence and high surface based instability can overcome the lack of sufficient shear, producing significant tornadoes."

"In the late afternoon and evening of 7 August 2003 two tornadoes produced significant damage across parts of metropolitan Palm Beach County, Florida. These tornadoes were produced as a strengthening updraft encountered cyclonic shear along an enhanced east/west sea breeze convergence line meeting a southward moving outflow boundary from the north."

That's hard to tell. It could be an updraft or scud type clouds. You can have scud clouds actually rotating? But it might not be truly a funnel. I'd have to see it again.

There was definite rotation on radar too, but does not mean it was a funnel cloud.

I'm also skeptical that no other reports were made of a funnel in a busy airport...

Watching WHDH now... no mention of it.

Headline is the microburst in Arlington.

Not sure what to call it... probably scud ?

Man that photo gets my heart rate up every time... I flew to Oklahoma and spent thousands of dollars this year and saw nothing that appealing.

People will tell you:

- it looks more laminar vs. ragged.

- it appears to have an associated wall cloud

- it was associated with a well-organized cell that had rotating velocities

But I agree with Coastal... could just be very well timed scud (the walk bridge obscures the lower portion).

Very hard to tell unless you see video confirming rotation.

Always people complaining...I didn't get this, this event sucked...blah, blah, blah.

This event actually did not suck and there were several microbursts/macrobursts throughout CT/MA and some areas were hit INCREDIBLY hard. When it comes to weather and especially convection not everyone is going to see something. When there are high risks issued in the Plains not everyone sees something there.

I just wanted some rain. I can't recall a summer where I have had so few thunderstorms.

Great event overall.
