Definition of a derecho is widespread damage over a greater than six hour period.

There are lines of storms that can do tremendous damage over a large geographic area but don't last six hours or do but don't get classified as a derecho.

I don't think saying "nasty line of storms" is a poor choice of words (hell, even call it a squall line).

Again, I'm not downplaying the line...it does mean business...but the "d" word is getting thrown around with almost every line of storms that develops...and it cheapens what a real derecho event is.

Given that it happened a week ago, it's a pure hype statement. Just call it a line of severe storms and avoid throwing out doom and gloom sh*t.

Damage certainly is possible...just think you shouldn't call it one until it reaches that criteria or has bonafide signs of it. This isn't that clear cut...

I've seen better looking lines of severe storms NOT called a derecho than what's coming down...and this line's pretty impressive..

I agree. Still shocked no watch box is out. Atleast give people the "heads up" on a Saturday evening.

I agree. It's one thing to go from Chicago to the eastern shore like last week's derecho, it's another to go from Ithaca to Wilmington. I think a strong line makes it to Philly, but it does not look like it lasts much beyond that.

A question: do people use the Derecho composite and MCS maintanence statistics? I've never seen them mentioned here but they seem to correlate pretty well with observed weather, at least the times I've looked..

that one cell coming into tamqua region has 70 plus mph winds....thats at 9,000 ft so maybe 50-60 at surface?

I have 20 minutes of video from that sucker taken right from my front porch. It was one hell of a storm...one of the best I've seen in years here. At some point tonight, I'll get it uploaded and post it for all to check out.
