I have to admit I never heard of that..something new to research.

my husband just came out and said we are going to get 75 mile on hour winds tomorrow...do you have a timeframe?

I will be looking it up. Thanks for the heads up.

I heard that the bow echo was forming. When
I looked at the radar about 20 minutes ago it
did seem to be more bowed, not so much so
now - hope it stays that way. Not an expert
just my observation - check your weather
often for updates and stay safe.





Nope i looked no bowecho. i think from the looks of the radar it looked like some clouds that just kind of resembled a bowecho.

Good luck everybody.

Thank you so much for the notice on this. That is one long snake of a storm.



The last one was very strange. No rain, but insane wind here. Stay safe everyone.

Again, thank you for letting us know. Much appreciated.

Thanks RealSpoke, bumped. I was right in the middle of that big red blister
in Illinois the last time, and it was a baby compared to THIS monster. A good
third of the trees around here got split and some even uprooted. When you
get a sustained wind of 70mph over most of a state it's time to yell "DorotheEE!"
Keep your UPS charged and your candles handy... we're goin' campin. It was
in fact a volume of hot air moving through quickly rivaling a Senatorial quorum.
Well maybe a distant second... we do have some legendary bellows fellows in DC.

just remember..... the weather reports are a guesstimate and not a true prediction. it may not happen and if it doesn't don't go blaming the weather guy/gal of fear mongering. it's always better to be safe than sorry.

I'm in the red zone as well. Never heard of a derecho before tonight, so I have no clue what I'm in store for.

I'm guessing it is a bad line of storms that can produce tornado's, hail, high wind and lightning, right?

Just coming in from watering to stave off the drying/killing hot winds here in middle mo. Thanks for the info I am passing it around to my network.

Thank you for posting this. They were predicting "very strong storms" on our newschannel this morning...
One thing people should get after the storm passes (before it is sold out again) is ICE! I know it won't last long but at least we'll have it for a short while before the freezers are empty again. Maybe (this is a long shot) the electric company is now more prepared to deal with this threat and can get people fixed up quicker this time.

The way it was described to us here in NE Kentucky/Ohio Valley/KYOHWVA tri-state area is that it is a "straight-line" wind storm and most of the damage is caused by highspeed straight-blowing winds. I'm sure it could spawn some tornadoes and the like, though. All I know is that it's very scary and destructive. Be safe.

I got hit from this storm system last night. It's been a long time since we have had rain let a lone a storm of this magnitude. I have trees down every where on the property and there are quite a few without power this morning. It was quite an amazing show of force .
Stay safe everyone.

(I don't know about these new terms like drencho and flash mob, I am an old guy and we used to call these things something else.: )

Mind stating what location? Im in the red as well-Ohio. Clouds are looking pretty crazy this morning already and not sure what to expect. All I know is I need to get home and get all my furniture off my deck before it lands in the neighbors windows!

Was that in Quebec ?
2 days ago i saw one big storm system at night
it was flashing like somebody taking a lot of picture outside
never seen the lightning so intense flashing the sky almost each seconds
when i went outside.. i saw a big mushroom cloud forming an arc
like a shield from the other clouds
i though at first that a plane flew through the clouds making a huge round arc line
i realise that a plane didnt do that
it was really immense and moved fast
each time there were a lightning the entire arc was illuminated .. beautiful

i was outside for 2-3 minutes before the rain came in fast
big wind with a lot of rain .. with the light from the mall i though it was a huge f5 tornado
80 000 peoples were put in the dark for 1 day (not in my area)
and with a lot of damage and also reported hail came in on certain area

weather hasnt been normal for the last 2 yrs but since 2012 has started
it is really really unusual on the entire planet

Heres a few videos from our derecho - May 8, 2009..The wind was incredible and the sound--20 mins of what sounded like the blow dryer at the car wash. Our home felt like it was being ripped apart.

Good information. Here's what Weather Underground and the Storm Prediction Center have to say about the same event.




Strong instability /MLCAPE of 2500-4000 j per kg/ and weakening convective inhibition will allow new surface-based thunderstorm development by about 18z across central Indiana/Ohio and west/northwest PA along the cold front and lingering outflow boundaries.


Around 1:00 pm CST the situation will be favorable for thunderstorm development around the cold front.


Convection will then grow quickly into multiple bands through the afternoon while spreading eastward across PA toward southeast New York and southern New England...and east southeastward toward northern WV/MD...in the 21-00z time frame.


Thunderstorms will form into bands and begin moving eastwards across the moderate risk area this evening around 5:00pm EST.


Convective Mode will become predominantly linear in the first 1-2 hours after initiation...with bowing segments the main concern.


During the first couple of hours, the storms will start to form squall lines, lines of heavy thunderstorm activity with heavy rain and gusty winds, possibly severe, and then the main concern is that some of these lines will start to bow; forming bow echoes or derechos which is a severe line of storms with torrential downpours, wind gusts of 60+ MPH, and frequent cloud to ground lightning.

On radar you can notice these lines of storms by their signature bow look on the radar. Here is the monster derecho that passed through the Ohio Valley and Mid-Atlantic last month



Photo Source: www.crh.noaa.gov...


Additionally... deep-layer and low-level shear will be stronger near the warm front this afternoon across southeast New York and adjacent areas...where embedded rotating storms and a couple of tornadoes will also be possible. Widespread damaging winds will be possible in multiple swaths given the strong instability...steep low-level lapse rates...dcape in excess of 1000 j/kg...and 35-45 knots westerly midlevel flow.


The winds in the atmosphere may cause enough instability to spawn rotating thunderstorms, known as mesocyclones, which produce severe weather such as hail, flash flooding, damaging winds, and the possibility of tornadoes. These storms may be embedded within the squall lines, or derechoes if they form.

Source: www.wunderground.com...

This is a broad overview of what they expect to happen throughout this evening in the moderate risk area. They frequently update this outlook as conditions warrant.

As several posters mentioned above, this may or may not happen, but there is a moderate possibility of it actually occurring.

Tune in to your local weather channels, or weather radio if you have one for more specific details to your location if and when severe weather hits.

Stay safe out there.

I think its like a bigger and more destructive verson of a bowecho. Bowechos also have strait line winds but they are short and destructive, and derechos are longer lasting.
