These storms mean business...

THIS IS A DANGEROUS LINE OF STORMS WITH A HISTORY OF WIDESPREAD WIND
DAMAGE.
WINDS IN EXCESS OF 80 MPH ARE LIKELY WITH THIS LINE OF SEVERE
STORMS! SEEK SHELTER IMMEDIATELY!

Very scary, and the SPC says that this may keep going and hit the VA/MD/DC/PA area later tonight!

Monster derecho bowing out! We'll be seeing some damage reports from these, no doubt.

Just saw preliminary reports of 70 mph near Detroit Metro Airport and 95 mph at Univ of Mich at Ann Arbor.

That truly is a classic bow echo!! Looks like a giant comma!

Up here in Omaha, we were in one last July as a derecho-type system moved across the state. The thing was is that the system collapsed before reaching Grand Island.

They are definitely more rare than the tornado watch version.

Particularly Dangerous Situation. When a situation is labeled as a "PDS" , either on a risk or just for a particular watch, significant severe is expected. Large, long tracked tornadoes, very high winds and/or exceptionally large hail is what is expected to occur.

-- Pretty amazing system heading towards Cleveland now. wow.

I was looking at some data from yesterday, 18z gfs and mm5 both showed a very good indication of this potent MCS...check for yourself. the front is coming back as a warm front now through PA and NY and instibilities are right in line with those models...so PA, NY NJ, CT watch out tonight !!

Here is a link to Cod's Satellite animation of this event, notice the faint line in front of the Bow echo, I highlighted the the current pic below.

Amazing outflow. Man, that whole line is booking!

Hi, this is my first post here. I found your site while searching for info about yesterdays storm. (great site by the way)
I live in Michigan and the green sky this storm produced was insane!! Could anybody tell me what causes the green color??

Welcome to Storm2K Lightning Face!
I've never actually witnessed the infamous "green sky", but I've read that it's hail. I liken it to shoveling some really deep snow (the kind with high water content) and how there's that blue-green hue when you look deep into it. It makes sense to me that an updraft of ice against a dark gray background would appear green.

I've also read that during a tornado situation it could be from the greenery it devours.

Thanks!
I have seen the GREEN MONSTER twice and when the temp. drops that fast and the green wall is blowing toward you-
here are some photos I posted over at "my home" message board. The green color really didn't come out that well because of the cheap camera. Just imagine that it is the color of the fleshy part of a lime

Great shot! Thanks for posting.

no problem! sorry for the quality. I need a better camera. I really wish the color would have shown up.

Major damage in elm grove wva from a microburst friday morning around 530am. Government declaring it a disaster area. The storms were terrible. I was awake from 430-715 helping pump out my basement. First time it flooded. Creeks were flooded quickly.
