Venture, where did that dryline end up? And what kind of outflow boundaries emerged from last night's storms? Enough to keep the big storms down some today?

Dryline isn't completely clear yet this morning since moisture is still up from overnight. But this is a good hint of where it will end up this morning...

Upgraded to Moderate Risk officially now...

Moderate risk is east of a line from Blackwell to Guthrie to Mustang to Ninnekah to Elmore City to Davis. So it includes all but the Western OKC metro counties.

PLNS...WHILE THE MAIN SFC LOW REMAINS NEARLY STNRY ALONG THE ND/SD

A WEAK COLD FRONT/WIND-SHIFT LINE ARCING SSW FROM THE ND/SD LOW
SHOULD ADVANCE ESE ACROSS CNTRL PARTS OF SD/NEB/KS THROUGH THE
DAY...WHILE FARTHER S...A DRY LINE WILL MIX E INTO SW KS...WRN

TODAY INTO TNGT.

...S CNTRL PLNS THIS AFTN INTO TNGT...
ARGUABLY THE MOST INTENSE...ALTHOUGH CONDITIONAL...SVR THREAT
APPEARS TO BE THAT ASSOCIATED WITH ISOLD TO WDLY SCTD STORMS FORMING
ALONG THE DRY LINE IN RESPONSE TO STRONG SFC HEATING BENEATH SRN
FRINGE OF UPR TROUGH. GIVEN 40+ KT WNWLY DEEP SHEAR /WITH A SIZABLE

BASED ON CURRENT AND FCST AFTN SFC CONDITIONS...THE AREA MOST LIKELY
TO EXPERIENCE SUCH ACTIVITY WOULD APPEAR TO EXTEND FROM S CNTRL KS
THROUGH CNTRL/ERN OK AND WRN AR INTO N TX. IF DISCRETE SUPERCELLS DO
FORM...AND...MORE IMPORTANTLY...REMAIN SUSTAINED...THE

COUPLE STRONG TORNADOES. THIS THREAT MAY MAXIMIZE NEAR SHALLOW WARM
FRONTAL FEATURE OVER CNTRL/ERN OK...WHERE SFC FLOW IS LIKELY TO
REMAIN SLIGHTLY BACKED. IN ADDITION...IF STORMS LINGER INTO THE
EVE...THEY WILL FIND THEMSELVES IN AN ENVIRONMENT OF INCREASING
LOW-LVL SHEAR AS THE LLJ NOT ONLY STRENGTHENS NOCTURNALLY...BUT ALSO
IN RESPONSE TO THE APPROACH OF UPSTREAM JET STREAK NOW OVER THE GRT

UNCERTAINTIES DO REMAIN REGARDING THE COVERAGE OF STORMS IN THE AREA
OF GREATEST BUOYANCY AS /1/ HEIGHTS WILL RISE THROUGH THE DAY
/ESPECIALLY FROM CNTRL OK SWD/ IN WAKE OF PASSING NEGATIVE-TILT

ANY SUSTAINED STORMS THAT DO FORM...A MODERATE RISK SEEMS WARRANTED
ATTM.

10% Tornado Threat with is also hatched for F2+ risk today includes the area east of a line from...Medford to Enid to El Reno to Lawton. It then runs north of a line from Lawton to Sulphur to McAlester to Stigler to Bentonville AR.

Dryline is nicely viewable on visibile satellite imagery.

Some patchy clearing taking place over much of the state, but we will need a lot of the clouds to burn off this morning for a real threat.

Here are the boundaries Anon is talking about...

http://www.weatherspotlight.com/screencap/may13/30.png

Got-DANG those are some top-notch illustrations! :D

Today's setup has me significantly more concerned than yesterdays. Tomorrow's as well. How does this compare to May 19-20?

Yay Paint Time! ;) LOL

Cloud cover seems to be burning off already up here on the Northside.

Cue bchris02's freak-out.

You do realize you can have the exact same setup and not get the same result? Comparing to previous events is pointless if you are expecting to determine the outcome of the day.

Cloud cover seems to be burning off already up here on the Northside.

Yes, it's already sunny in NW OKC. Not a good sign.

Probably about 50% burned off downtown.

Yes, it's already sunny in NW OKC. Not a good sign.

The amount of sun in one very localized area isn't nearly as indicative of the broader atmospheric "pot" as one might imagine. I'm in E OK County and the cloud deck is thick like cotton candy over here. The key is the broader region of the atmosphere either being heated due the general absence of clouds, or being kept cool by the general presence of clouds. That satellite vapor imagery shows a pretty substantial cloud deck at the moment generally over the state, and so long as that is present, it generally mitigates the atmospheric heating. Note the intentional abuse of the word "general" :) That's because the best any of these forecasts and assessments can do is give us an idea of the structure and condition of the atmosphere and a best notion of where things will be later on. To try and draw exact comparisons or parallels to a week, a month, or a decade ago is just going to give you a bigger Excedrin headache. :)

As an example of this, just look at how volatile the forecast has been over the last 24 hours for really no other reason than the cap (yesterday) and the presence of outflow boundaries. We didn't have the outflow boundaries yesterday, today they're here, and that's a monkey wrench in the forecast. It really blows apart the idea of trying to draw perfect analogies between any two given days. Its tempting, but frought with peril :) Much less stressful, at least for me, is to just read the forecasts as best I can (with some good help) and assess each day as it comes.

The weather channel has a 6 of 10 on its TOR CON index for the OKC area.
It was a 5 on May 20.

Dryline has pushed to: From Grant to Custer to Jackson counties now. A lot of multi-level clouds inhibiting full heating. But some average heating is taking place NW of the OKC metro where clouds are thinner.

NC OK has some good heating taking place.

Once again this map is a good indicator of heating levels:



http://www.mesonet.org/data/public/mesonet/maps/realtime/current.SRAD.grad.png


6-700 range is near full heating and getting into 800s once afternoon rolls around.

Not good. I definitely have a feeling this is going to be a bad day. Hopefully whatever does far stays away from the most populated areas.

You do realize you can have the exact same setup and not get the same result? Comparing to previous events is pointless if you are expecting to determine the outcome of the day.

Last year April 12-13 looked to be a major tornado outbreak, and all of the ingredients were in place. And there were tornadoes (Norman was hit by a small one) but nothing like May 20, where one large tornado hit a populated area. If I remember correctly it was compared to the May 3 setup at the time.

That's precisely why its so important not to compare the "setup" of Day X with any other day, and why things like TWC's TORCON business just increase people's anxieties.

You have to kind of separate feelings from data. Yes, there's a chance of severe weather, maybe tornadoes. Don't let the TWC "TORCON" business heighten the anxiety. What's it really say? There's a nonzero chance of a tornado, just as there was last week. We knew that already. But TWC splatters it on a big, red map with bold TORCON letters just to...attract people to their big, red map with bold TORCON letters on it. No offense to folks who like/watch TWC, but I'm more an advocate of informing rather than inflaming. TWC calling some big attention to the difference between a TORCON of "5" and a "6" is precisely that, IMHO.

You have to kind of separate feelings from data.

And that's exactly what the Tor con index does for very busy people and for people who have a low understanding of the weather….
And they make up the strong majority of people.

This apparently occurred in Norman last night

http://i.imgur.com/Hdcmds1.jpg

http://www.srh.noaa.gov/images/fxc/oun/graphicast/image6.jpg



Isolated supercells with severe weather including very large hail, tornadoes, and damaging winds are expected to develop near or just east of a dryline across mainly central Oklahoma between 2 and 4 pm this afternoon. Exact storm initiation times and locations may change.

And that exactly what the Tor con index does for very busy people and for people who have a low understanding of the weather….

Sorry, ou48A, I strongly disagree with that. It does nothing to aggregate information. It just inflames and frightens.

We hashed this out before, so let's not do it again. We just have to agree to disagree.

I would not be surprised to see the MODERATE risk pushed back south and west. We will see in about half an hour.

General clearing still taking place from N of the OKC metro back to the SW. Temperatures will be in the 80s by noon over much of C OK.

Completely agree.

I'll gladly settle for another rainy day/night, like last night, where rain was about all that happened heavily, though some people had to get some hail and high winds. Or in other words, where the OKC TV stations don't dwell full time to give out bad weather. What a supreme blessing when there is a thunderstorm and that isn't happening.

An area just to the north and west of Stillwater got 4 to 5.28" of rain last night.

You may disagree and that fine but it’s not up to you to decide what’s best for other people.
The WX channel has a team of MET’s and others who have researched what it takes to reach the public.
I just wouldn’t worry about it if I were you.

You know, I wish you guys would get more specific with when its going to rain, I need to mow my lawn.....

;) No, really, I've been quietly following you guys for a while now. I had my eye on you when storm went through my hometown of Piedmont a few years back and felt like I had hours to prepare before the storm actually hit. Last week, I work at SW 89th and May, I was following you guys and scattered like a cockroach a good 20 minutes before the news had us running. Plus you refrain from all of the hysteria.....Just wanted to give you a shout out and say thanks.

1124am - experimental wx balloon from @NSSL shows the cap is fairly weak. Could get storms in the next hour or two. Stay very alert! #okwx

New risk area is nearly unchanged, slightly trimmed off of NC OK where there is ongoing convection.

I feel like the SPC may be discounting to the SW near the Lawton area.

TORCON doesn't get into any specific or really help. They could put out a TORCON of 10 but if the cap is too tough, it is a worthless number. They don't release the components of what makes it up which doesn't help credibility any. The SPC's Significant Tornado index at least has the formula available to the public so we know what goes into it.

This thread is about providing information, not hype. If TWC releases the criteria of the TORCON number so it can be vetted then we can discuss it then. In the meantime, keep the hype out of this thread.

First legit echo along dryline has popped up NW of Lawton.

So does this look like a classic setup where supercells move up I-44 into the metro?

The weather CH is has plenty of reputable meteorologists some with PHD’s.

The Tor con index has value for some people. Because not everyone knows near as much about the weather as do most of us, and until Pete PM’s me and ask me to do otherwise I will continue to post the Tor con index. The WX CH understands that they must try different methods of getting people’s attention. Even the NWS has started using stronger language because their studies have determined that this is what it takes to motive some people. If it really bothers you just don’t pay any attention to it, or you can always put me on ignore if you wish.:)

The southern end of the complex of storms in NC OK is showing supercellic-structure. This could entail what type of storm formation we have along the entire dryline later. Linear complex with embedded supercells.

The longer the dryline waits to fire the further south you go, the more potent storms will be able to become.

The NWS using strong language is usually coupled with a description and explanation of what's going on. Not some arbitrary number. However, if you choose to behave this way that's on you. Enough time has been wasted on this and that's not what this thread is for.

I equate the TOR-CON index to women's clothing sizes. Arbitrarily selected numbers, the higher the number, the more alarmed they want you to be.

Yeah right, more like marketing and upper management who told meterologist to assign a number from 1 to 10 to an area.
Reminds me of the terrorist attack alert level system that the government eventually changed because people stopped taking it seriously after awhile.
But whatever. lol

Surprised no MD out for C OK yet. They must be really trying to figure out what is going to happen before they issue anything.

Also I am surprised that Noble county is not under any warning right now.

So...I'm supposed to take my hail-damaged car into a body shop for an estimate today at 3pm. Reschedule? :Smiley259

Very strong wording on that MCD. Please stay alert. We are chatting through the event so feel free to drop in.

Okay, I keep seeing the phrase "discrete supercells" thrown around, and I've pretended to know what that means, but I don't. Mind explaining that one to me?

Instead of a cluster of storms together...discrete supercell are your individual cells spaced apart with strong mesocyclones.

I am grabbing lunch and will be in the chat in a bit.

Theta-E right now along the dryline is insanely juicy. The later the dryline waits the more potential this event has. Watch for winds to start backing and becoming favorable later this afternoon if everything holds tight and allows the heating to continue.

Sweet -- I always wondered what they called those? It seems like they are always a whole lot worse when they are alone. I just called them "individual" supercells in my head.

But please know there are those who do find it useful because it’s quick and simple.

Talk me down: the position of the frontal boundary / dry line seems eerily similar to May 20, except air temp is even hotter. My daughter gets out of school at 2:30 in OKC. Pros: what do you think?
