This is one of the best action videos I have on record. I always thought lightning was the way to go but now after seeing this man am I wrong. Really when you least expect it the weather can do some really strange and wonderful things. -- johnstownwildfire

This is great -- BeckyMarie

Great stuff -- tonykelly

How did you do this. This looks like someone pouring liquid nitrogen down on the valley below -- Roxys

Do you see those birds. Right before the cloud hits the trees in front the birds can feel the cloud and they take of flying for their little lives -- flowersforsara

This was actually done with a relatively quick camera - Kodak Z710 - and Quicktime software. I will write a more detailed tutorial on my blog later, where I have featured this film tonight http://community.accuweather.com/ -- weathermatrix

What birds. I must need glasses , na just teasing the birds are crows and they had just landed in the tree sin front of m to the side of me behind me. Heck there was maybe over 1000 crows that were flying around, they landed and when the storm crested the last ridge there they all took off. Almost like this built in clock said hit the road jack. -- johnstownwildfire

I see the birds, this sir is a super super movie. I hope like you get a prize for it or something. -- jodimiller

All I can say is ....FREAKIN awsome -- MWhit

I used to live in Ebensburg, and views like this over on Chickoree Hill are something I miss a lot. I have lived in Michigan for the last 40 years, and I still miss the mountains and the views like this! Great photography! -- bobduman

Very unusual and very cool. -- depthdose

Hey the fog keeps getting pushed around... it is way better than the lightning -- jodimiller

That type of Fog is called upslope fog!!! It happens when the T equals Td and since it is going up the mountain the td is the same going up following the Lapse Rate of the Adiabat. -- asdasd01

Thanks asdasd01 but what is Adiabat. -- flix

Very very cool. Reminds me of the fog burning off as it descends the east side of Twin Peaks in San Francisco... kind of the reverse of this as the eye sees it. This is more fearsome though. -- rando

Again after effect of UFO's in the region. -- BlueJay

I Love this video! -- miketarg

Most of the unusual weather we encounter in Oklahoma is of a violent nature. This, however, is of an almost scary nature. How did you happen to be in the right place at the right time? -- VWfan

Reminds me of the fog over the Golden Gate Bridge with the supports poking through the tops, and the poetry of T S Eliot: 'the fog creeps in on little cat feet' -- john.rhoads
