Pictures of a beautiful LP supercell just north of Red Deer, Alberta taken by Elaine Cripps:











Pictures of a shelf cloud taken near Edmonton, AB by Dale from late Monday evening:






Pictures of the Edmonton storm courtesy of Mike M:
(Mike reported 60-90 km/hr winds with this line of storms!)




Severe thunderstorms pounded area under Edmonton and also just north of Red Deer, Alberta this evening.  An INCREDIBLE low-precipitation "LP" supercell developed southwest of Red Deer and tracked slowly northeastward...likely producing very large hail and possible funnels.  Further north, severe thunderstorms moved through Edmonton during late evening, bringing hail and strong straight-line winds and even possible funnels over South Edmonton.  Here is the radar image from when the supercell was at peak intensity:
As of 9:45 pm MT, severe thunderstorm warnings will still in effect for the Edmonton, AB area, as a broken line of elevated storms was moving east off the mountains.  Shown below is the watch/warning display from Environment Canada at the above time.  I'll hopefully be posting pictures of the Red Deer supercell, along with pictures from the Edmonton storms shortly...the structure was TEXTBOOK!

Also thanks Heidi for checking out that link. The last thing NZ needs right now is heavy rain especially in the upper north island. However i do hope that it produces an impressive storm.
Cheers...

Check out the pictures of the Red Deer supercell taken by Lainey...I just posted the link above. AMAZING structure!

Looks like there could be a funnel in one of the later pictures.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Reed | July 24, 2007 @ 12:56 AM #

Candy...these storms are rather strong supercells and could produce hail up to loonie size and strong straight-line winds. Tornadoes can't be ruled out, but right now, the storms do not look tremendously organized.

The models did not forecast the CAPE and low-level shear very well today...but I just glanced at the RUC analysis and the low-level shear is analyzed stronger than previously forecast.

Does anyone know if tornado warnings were issued for the Red Deer cell earlier this evening? I was away from the computer for a few hours..unfortunately!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Matt Chat | July 24, 2007 @ 1:15 AM #

Wow, those pictures of that LP supercell are BEAUTIFUL! I need to chase something like that IMMEDIATELY!!! THe only LP storm i've seen/chased that looked better than that was the NW Oklahoma May 4th storm. I think reed might recall which one i'm talking about.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Kenny | July 24, 2007 @ 1:18 AM #

There are a few shots of the storm near Red Deer at the link above.
Was certainly hoping for a better show!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Mike R | July 24, 2007 @ 7:14 AM #

the center of the lp supercell passed between millet and wetaskiwin. both towns were hit hard millet got heavy rain while wetaskiwin got none.
As the storm was over Wetaskiwin 10 lightning strikes hit
near Wetaskiwin in one burst killing power for hours. I have never seen
Wetaskiwin so black
Branches and debris litter highway 2A north of Wetaskiwin and even a whole tree have blocked the road
I have video of the lightning but none of the burst of the aftermanth.
I addition 100kmh winds came in

Nice pictures guys!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By zack | July 24, 2007 @ 9:24 AM #

Incredible pics!!!! The structure w/ those storms were absolutly A-M-A-Z-I-N-G!! Definently TEXTBOOK!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Mike R | July 24, 2007 @ 9:55 AM #

The sad part of the wetaskiwin supercell was the fact that it was dark out, but i did get some detail on video from the lightning.
Wetaskiwin was between the shaft and the updraft. In fact A possible tornado touchdown in wetaskiwin but F0 in strenth so no damage, the high winds lasted only 15 seconds and were localized thus a possible tornado just before the outage.

I first saw the edmonton storms fron pigeon lake.
I was hot so I went for a swim @ mulhurst.
I left at around 8:30pm

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By zack | July 24, 2007 @ 10:07 AM #

Had some storms around my region yesterday... The storms were not severe, but just under severe levels w/ 40-50 mph winds nickel size hail and they also put down a ton of rain!! My street was a river during the storms!!! And now it is 10:06 am and once again we have more shwrs and storms, but they are weak and dying out.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Kenny | July 24, 2007 @ 10:15 AM #

I still loved that storm...I filmed most of it 13 min to be exact and got some pretty good lightning :) 3 bolts at once

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Dale | July 24, 2007 @ 10:24 AM #

Sent you the pictures reed.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Heidi | July 24, 2007 @ 10:48 AM #

That's a really nice series of pictures, and really cool that we're able to see it from so many different angles. Nice job everybody. :D

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Mike | July 24, 2007 @ 11:17 AM #

i noticed yesterday during the storm the wind was going north then instantly went south.. was wierd

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By zack | July 24, 2007 @ 11:37 AM #

The wind shifted Mike...Usually happens when gustfront passes... Say the gustfront was comming in from the north and the wind was blowing from the south. When the gustfront moves in the wind immediantly shifts to the north and thats when it gets real windy!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Mike | July 24, 2007 @ 11:40 AM #

Makes sense cause i could see the gustfront (low fast moving clouds) kicked up a dust storm cause its been so dry here

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Reed | July 24, 2007 @ 11:46 AM #

Thanks for the pictures Kenny!

I'll be posting them on here shortly.

Incredible striations on that shelf cloud.

Hi Reed, i sent you some pix of Edm sky last night...just to the email on your media section, hope that's ok. i enjoy your site btw.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Kenny | July 24, 2007 @ 1:17 PM #

This was a nice storm haha. And thank YOU Reed for putting them up :) Me and my friend chased that storm on our bikes before it pretty much started.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Kenny | July 24, 2007 @ 1:26 PM #

Btw Reed, on the last picture i sent you, you can notice by one the last house there is a possible funnel. I didn't notice it till i reviewed the pictures.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By matt | July 24, 2007 @ 1:31 PM #

excellent post reed, amazing pics guys. The jealousy runs deep!!!

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Lainey | July 24, 2007 @ 1:47 PM #

Reed asked "Does anyone know if tornado warnings were issued for the Red Deer cell earlier this evening? I was away from the computer for a few hours..unfortunately!"

Reed, no tornado warnings yesterday at all that I was aware of.

On another note, I was at the car dealership today and someone brought in a car that was just POUNDED with hail yesterday - windshield broken with multiple hits, large pits on the roof, hood etc. Maybe they were caught in the Red Deer cell. (wonder if they got pics?!)

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By kenny | July 24, 2007 @ 4:27 PM #

Reed i have some more pics too but first put those up.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Sonia | July 24, 2007 @ 7:18 PM #

The storm that hit "north of Red Deer" actually hit Blackfalds... I am in Red Deer and we didn't get anything right in the city yesterday. A coworker of mine who lives in Blackfalds says they got small hail. And no, there was no Tornado warning or watch issued, only a severe thunderstorn warning.

On another note, we JUST had a rather dark shelf cloud come over Red Deer but no precipitation... winds picked up and it was rotating... we're only in a thunderstorn watch at the moment. It is moving slightly east/south east.

INCREDIBLE supercells/shelf clouds across Alberta on Monday! Comment Posted By Lainey | July 24, 2007 @ 9:24 PM #

Sonia, Saw that one earlier today too. Did have some rotation, it dropped rain here to the N, but nothing too bad.

Thanks for putting my pics up, Reed. (scarcasm)
