Severe weather outbreak likely in Alberta today

Related Categories: Tornadoes
As a strong shortwave trough ejects northeastward across the Canadian Rockies today (Thursday), the ingredients are coming together for a significant severe weather outbreak across Alberta for the Foothills and the adjacent Plains in the region highlighted in red on the selected model plots below:

Shown above is the WRF forecast CAPE (instability) for 6:00 pm MT this evening.  CAPE values of 3000+ J/kg are widespread across the entire Foothills and adjacent Plains of Alberta, given the very high moisture values and relatively cold air aloft.  Southeast portions of the province have very high instability, but a strong capping inversion will be in place, which could suppress storm development for much of the day.  However, if a storm initiates in southeast AB (outside of the red shaded area), it will still rapidly become severe and will pose a tornado threat.  However, the best dynamics are located to the north of this region in the red shaded area.  Shown below is the forecast 12-hr accumulated precipitation ending at 6:00 pm MT.  This shows widespread thunderstorm development from north of Calgary through Edmonton, and northwest along the Foothills/high plains.  These storms will likely be supercellular.


There is one negative on the tornado potential for tomorrow -- fairly unidirectional flow between 700 mb and 500-300 mb -- as seen below in the WRF forecast wind panels.  For the tornado chances to be maximized, the wind should veer to a more westerly direction with height (which is not the case here), because this results in greater storm motion-relative wind shear.  For tornadoes to occur tomorrow, right-turning supercells will be necessary.   If there were more directional shear forecast between low-upper levels, then today would likely be a much more significant tornado outbreak.  But...tornadoes are still very possible with any storms that deviate right of the upper-level flow.  Stay tuned for updates...I plan on posting SEVERAL blog entries as this volatile severe weather situation unfolds!!

Unfortunatly Reed will be like most of us, stuck to our computers watching this, as it unfolds.........! I hope if any tornado's happen someone handy with a camcorder can capture it for our veiwing pleasure! Those who are chasing STAY SAFE!

Severe weather outbreak likely in Alberta today Comment Posted By Matt Chat | July 19, 2007 @ 2:16 AM #

Yeah, tomorrow does show some real decent potential. I wish there was a way I could just transport myself over 1500 miles instantly. I'll probably be watching more insane supercells in canada once again from the comfort of my home. Reed needs to keep up the good job of getting pictures and footage from the nice caniadian residents for tomorrow!

NCAA 2008 dominating is well underway. The Texas Tech airl assult cannot be stopped!

Ok i have a question for you guy's.In the very top graph image labeled SBCAPE,is the region that is highlighted in red a present image or is this where this will be later in the day.I mean it is early morning hour's still but i really would love to know as the weather network isnt giving us any solid info on this severe weather that this graph is showing.All it say's on the screen is that in the afternoon time we can expect some thundershower's and that is all.Really no in depth coverage.

This weather network is really slow with update's and after the past few severe thunderstorm's that rolled on by they had not really mentioned it for the area.

Ok they came on live and said there are tornado warning's right now for Calgary.Severe weather rolling across the region sound's like mainly between edmonton and calgary.

Thank's reed for the very valuable info.

Dale if i had a ride ide be right there with ya buddy......have fun dude and be safe.

hmmm..... global warming?????! climate shift happening? right now?!?

Severe weather outbreak likely in Alberta today Comment Posted By Mike | July 19, 2007 @ 7:17 AM #

Yah Cors, i think that global warming has to do with all these storms, all around the world, like in china they got like a 13 hour storm and around a foot of rain, thats crazy

Severe weather outbreak likely in Alberta today Comment Posted By Diana | July 19, 2007 @ 7:18 AM #

Uh, there's no tornado warning over Calgary. I was just woken up by some thunder, but it's just beginnng to pass over the city and so far doesn't look too severe.

EC has not so much as a severe thunderstorm watch out for us right now. I know they're a bit slow, but there's definitely no tornado warning just yet. Most of the action looks to happen just to the north of Calgary for the greatest threat.

Severe weather outbreak likely in Alberta today Comment Posted By Mike | July 19, 2007 @ 7:18 AM #

But i still think global warming could just be a cycle and that we will cool down eventually

Wicked pics...

Good morning everyone.

Severe weather outbreak likely in Alberta today Comment Posted By Mike R | July 19, 2007 @ 8:02 AM #

I like right in the middle of the tornado area(Wetaskiwin).
I think the situation in alberta is so volitile no one can figure out what to do. Setups like this are a rare event in canada so EC has little experience with it.
There are two things that i think this will do
1. The setup sets in for tornadoes and skies go nuts.
2. the system goes monsoonal and torrential rains hit with two feet(600mm) of rain possible

weather is totally unpredictable. today can definetly turn into a bust...but the WRF models for today, like the ones reed posted above, is a damn good indication that we are in for some severe weather.

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 8:30 AM #

Very valuable info. Reed!!! Looks like you folks in Alberta are instore for some pretty nasty storms...

Keep me posted on this one!

Even if your could come to Alberta yo'd be runing for you life at the sight of gas prices @ $1.17/litre, thats $4.47 a gallon

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 9:13 AM #

Wow Mike thats some expensive gas!! I would be running for my life!!

The gas prices around my area are near or above $3.00.

Severe weather outbreak likely in Alberta today Comment Posted By Susan | July 19, 2007 @ 9:13 AM #

Thanks for the info, Reed! I live in Didsbury, about 45 Km north of Calgary and I've been an avid weather watcher since the Edmonton tornado years ago (I was 12 at the time). I appreciate your forcasts and what I have learned on the site.

Hopefully we miss the big storms today as the hay doesn't need to get any wetter and the grain doesn't need any more hail! My Dad and brother were caught in baseball sized hail while working in the field near Cremona on Sunday. We've never had hail that big in these parts, at least not in the last 50 or so years. The weather has been very interesting up here in the past few weeks. Reminds me of when I lived in Ohio!

sy coundt resist here is the new picture of the funnel..at least I think its one.

Cors - way to go! that must have been pretty exciting for ya! :-D

Severe weather outbreak likely in Alberta today Comment Posted By Rene | July 19, 2007 @ 9:28 AM #

I have a question

When severe weather is a foot. How does Barometric? pressure comes into play ? When the value goes up or down? How does that affect the Storm ?

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 9:51 AM #

I wish I could answer that question for you Rene..
I have an answer but I don't know if its correct. I do know one thing about barometric pressure though, usually when its falling it means that there is low pressure in the atmosphere if it is rising there is high pressure. Hope it helps.

Severe weather outbreak likely in Alberta today Comment Posted By Mike R | July 19, 2007 @ 9:51 AM #

Looks like a dry line may form along the QE2. Cooler to the west(15-20C) and warmer to the east(20-25C) as of 8:00AM MDT


Looks bad for the rivers. possibe flooding of the rivers if severe storms continue all day.
a storm can put down several inches of rain rain in a very shot time

Severe weather outbreak likely in Alberta today Comment Posted By Rene | July 19, 2007 @ 9:53 AM #

Envrionment Canada has dowgraded Alberta from Warning to Watch

damn!!

Severe weather outbreak likely in Alberta today Comment Posted By Heidi | July 19, 2007 @ 9:54 AM #

Rene: I'm not a professional, but I think I can give you a sort of simple, non-technical answer to your question, if that's what you want.

When severe weather is approaching, generally you should expect to see the pressure dropping, as a trend; when the weather "system" that causes the severe weather has passed, the pressure should rise again.

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 9:55 AM #

Mike, I thought the dryline separates the moist air from the dry air....

To me it sounds like your describing a cold front.

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 9:58 AM #

Darn!! Your right Heidi I was thinking that but couldn't put it into words.

Severe weather outbreak likely in Alberta today Comment Posted By Mike R | July 19, 2007 @ 10:27 AM #

IT seems to be a boundery of some sort or it may be that east has sun heating and west does not.

We will just have to see if the foothills get sunshine like farther east. as sunshine will add a good 5C to the temp
and thus more instability
The sky here is hazy with currosratus and cumulus
22C 78% humidity
no wind
+3C from morning low

Spruce Grove, Alberta right now is dark sky, downpours, lots of thunder and lightening.

Severe weather outbreak likely in Alberta today Comment Posted By BRB | July 19, 2007 @ 10:50 AM #

Has anyone here heard of an almost certain tornado threat for Red Deer-Ponoka-Innisfail-Stettler. Reed made a good point about how the wind blowing in a westerly direction for the storms to get rotation is the key to getting a tornado.. well at least a moderately strong tornado.. does anyone know if a tornado does for of how strong it will be?

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 11:00 AM #

Hey Rene, I have a website that you could check out if you want. Im pretty sure you know most of the stuff on it, but it gives you a pretty detailed look on how they form.

no body knows untill its happening or its gone and usually its by sight brb... the f-scale was not a wind speed indicator so much as a damage indicator. theres still a large amount we dont know yet.

ok...ill admit it... i still use jet stream school... its kool man!!! lol

hey cors..kool pic...i have a pic just like that...a cold air funnel...kinda like running your hand through water real quick to make a votices..they are there then they go fast . at least thats what it looks like without the wall cloud. so tell me cors what did you guys do over there to get such severe weather this year ? lol

Severe weather outbreak likely in Alberta today Comment Posted By Simon E. | July 19, 2007 @ 11:11 AM #

BRB: I will actually soon be talking to some folks at the University of Alberta who have been investigating that very thing; If you can, try to remember to ask about forecasting tornado intensity in Alberta in about three weeks, I should have some more details for you...

The work looks really rough right now, and it doesn't take into account a number of other factors that could affect tornado intensity, but it's definitely a start!

Simon E.

Severe weather outbreak likely in Alberta today Comment Posted By Reed | July 19, 2007 @ 11:12 AM #

Wow..there are some early risers on here!!

The more intense storms won't develop until late this afternoon and evening. The storms out there now are elevated, which means that they are based above the surface, and will only pose a marginally severe hail/wind threat as they lift north and dissipate.

We need the heat of the day for the significant instability to develop. I'll be posting continuous updates as the situation unfolds. As Brandon, said...this situation could easily not produce any tornadoes...the flow is very unidirectional with height, which is not ideal...but if storms turn to the right then they will have a better chance to produce.

I have lots of reading and learning to do tonight..
anyone have anymore sites ?

Severe weather outbreak likely in Alberta today Comment Posted By Dale | July 19, 2007 @ 11:14 AM #

hey reed... ya its like that in alberta..its very hit and miss...we should get by rights about 50 or so tornadoes a year yet sometimes we get 15..go figuire. so this means we have time before we chase...so i can go see transformers movie again? lmao

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 11:14 AM #

Dale, I took a look at the site you posted for Rene and your right it is kool lol!!!!!!!!!!!!!!!

ya the glossary index is good for the wild weather acronyms. glad you like it zack.

Severe weather outbreak likely in Alberta today Comment Posted By Joel | July 19, 2007 @ 11:19 AM #

Wow! Wish Reed and I had gone up to Alberta. Morning models continue to show a potentially volatile situation this afternoon for areas north and east of Calgary. Wind speeds at all level should be very high. The only negative I can see is there may be a lack of turning with height, limiting shear a little bit. CAPE will be high and convective inhibition should be gone by mid afternoon. Look for several fast moving supercells to develop and rapidly fly north to north northeast.

Severe weather outbreak likely in Alberta today Comment Posted By Mike R | July 19, 2007 @ 11:22 AM #

Alberta has less tornadoes due to the fact that dewpoints nomaly don't exeed 15C. This year a hot humid airmass is in place and will not die out(just like 1987).
Muggy weather will retern to alberta in the next week, so take advatage of the more bearable conditions
Another thing is that alberta is big so the chance of a tornado in a city or town is low(even if there are many tornadoes)

Severe weather outbreak likely in Alberta today Comment Posted By Dale | July 19, 2007 @ 11:26 AM #

well i know this mike...doesnt mean i gotta like it lmao.

The new RUC (Rapid update cycle)model is showing supercells from near Calgary up through Edmonton at around 6-7 pm, with very good wind shear. This is a model though, and I've seen it blow many a forecast!

This model has even better shear than the WRF shown here...it updates every hour.

I may not live in Alberta Kelly, but I feel the exact type of weather you do. I live in Oklahoma and the weather this time of year is usually hot and dry(boring too). But this year the dewpoints have been in the upper 60's to low 70's making it feel more like Florida or Hawaii!! We have also been experiencing a wetter than avg. spring and summer as well.

It sure does feel like the caribbean, erie isn't it?

I wish i had a car i would be out chasing, but if something comes to south edmonton there is a hill i can see everywhere but the north so i guess that will have to do

I work in Spruce Grove but live in Onoway so I will keep posts on here throughout the day and night. Exciting isn't it?

Severe weather outbreak likely in Alberta today Comment Posted By Reed | July 19, 2007 @ 12:49 PM #

Yeah these dewpoint values are extreme for Alberta...especially northern AB. It looks like there could be another trough building in the extended range (a week+) after this one.

It looks like the skies are very clear over most of the foothills and adjacent plains. We should see some towers developing in a few hours.

Clouds in Spruce Grove are burning off, skies are clearing. Although reports of a large storm near Evansburg was called in to our office.

Matt, ya I know where you are, it would take me 1/2 hr to get there.

I remember driving on the 400 hwy, coming back from the cottage, the clouds were so black, it was 1pm and I had to turn on the driving lights to drive. it was almost night time. never seen that before..

it was north of the Ski Hill off of the 400 hwy. when it ahppened. Then when we reach the skii kill, the black cloud covered half of the ski resort. it was awesome

Alberta's watch was just extended to the southern areas.

Severe weather outbreak likely in Alberta today Comment Posted By Kelly | July 19, 2007 @ 2:18 PM #

From Environment Canada.

A developing north south frontal zone from just west of Edmonton south to west of Red Deer has begun to pool moist unstable air. It is expected that thunderstorms could begin to trigger near this boundary after 3 PM and well into the evening hours. Storms which develop are expected to move northeastwards. It is possible this watch may be extended southeastwards towards Medicine Hat as the day progresses.

Hot spot over Camrose,Wetaskiwin and Lacombe.
it is 5C warmer than Edmonton or red deer
Dewpoints around 23C
If it behaves like 1987 Edmonton is in for an F5!
Station records(1987) show the same hot spot south of Edmonton.

A more powerfun version of the dynamics on july 31 1987 is developing
All that is needed for a super twister in edmonton is the wind shear and upper support

Currently:
30C
60% humidity
Flash covection is happening just like 1987.
I will watch this very closely and so should everyone else
Clouding over very quickly

63% humidity
dewpoint 22C

Mike R thanks for all these updates i live on the very southern part of edmonton so its good to know if i should be concerned

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 3:04 PM #

Mike R you should chill a little...

What if NOTHING happens?!?!?

Severe weather outbreak likely in Alberta today Comment Posted By Jackson | July 19, 2007 @ 3:07 PM #

Category:tornado

State:Texas

City:San Antonio, Home of spurs (NBA)

Rating: F-1 (San Antonio is not really in tonado alley)

Side of city: Northeast side

Time of day: About 3 a.m. Tuesday Night

Man, you should have been here, the rating was a strong F-1 and had winds of 100 mph

We've also been having flooding too, but it's clearing up though. Peace

Severe weather outbreak likely in Alberta today Comment Posted By Mike R | July 19, 2007 @ 3:19 PM #

yes it is possible for a flop. and many would rather it be
But it is always good to eye the sky in weather like this.
I'm saying an F5 is the worst case, but it is possibe.
The size of the hail is more of a concern as all it needs is a powerful updraft. While a tornado needs and a very complex set of conditions. Tornadoes are certain today but big ones are way less likely

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 3:28 PM #

Well I got to get away from the puter for awhile...

Good luck to all of you chasing in Alberta today and BE SAFE!! I'll be watching the situation closely..

See Yall!!

Severe weather outbreak likely in Alberta today Comment Posted By zack | July 19, 2007 @ 4:18 PM #
