Looks like that one might skirt the west side of OKC...Morgan said that one had reports of baseball sized hail.

Circulation is down on the west side storm. Hail is over 3" now on radar estimates.

EDIT: Appears it is cycling. Inflow notch is developing again on it...and it has split off from the line. Tail end charlie go.

got any good chaser feeds your keeping up with Venture?

looks to me that the Blaine/Canadian storm is breaking off and going more SSE than the main line which is continuing SE..

Sorry, went to see Star Trek...so back to work now


WHAT???? We need you.... next time, give us advance warning. lol
westsidesooner has been keeping up informed while you were gone ....

Honestly though, I'm seriously getting nervous right now.

Interesting break in the line now. Will need to watch to see if rotation improves in either storms.

I'm just now waking up. I'm going bowling on Sunnylane with friends. Gotta get ready now. :omg:

Nice hooks. Interesting, indeed, Mr. V!

ha! I'm liking how there is a nice space/break that might just miss all of us here in Edmond and the Metro! Yay!

well.. looks to me like OKC proper's excitement for the day was really early this morning.

Looks like right now the western and NE Metro will be the only parts impacted. There are some indications the line may try to start filling back in again soon. Also additional moisture is moving in the from SW to maybe get the dryline in play here. However it looks like the cap will hold in that area right now. We'll have to wait and see though.

Thunder, you should open a bowling center, and call it Tornado Alley.

ripley to 3 miles southeast of cedar valley...moving southeast
at 20 mph. The largest hail will fall along the western
portion of the line.

Hazards in the warning include...
Hail up to the size of golf balls...
Wind gusts to 60 mph...

* locations in the warning include edmond...guthrie...northeastern
oklahoma city and stillwater.

is it just my sense of time, or has the line of storms slowed down?

Maybe, it's just you partaking in the Gary England drinking game. j/k ...

I've long given up on trying to understand the OK weather ...

Large hail core with hail over 1" will pass along the central and eastern sides of Edmond in a few. Looks like it should stay east of Kelley. Additional back building development is possible. Storms have transitions to the hail/wind threat, tornado threat should be very low for the rest of the night for the metro.

New tornado warning for the Gracemont area.

Another area of interest will be 4 SSE of Mountain View or 6 NW of Alden in SW Oklahoma.

Anadarko - Gracemont area..... Tornado - you should be in your shelters.. be safe!

Circulation moving into Anadarko right now, but is weakening. Law enforcement reporting wind damage to trees in the area with winds around 60 mph.

Line of storms now building back to NW Expressway and Mustang Road. OKC proper should expect storms with 1" up to 2" hail possible over the next hour.

severe thunderstorm watch number 298
nws storm prediction center norman ok
940 pm cdt wed may 13 2009

the nws storm prediction center has issued a severe thunderstorm watch for portions of

northwest arkansas
southern and eastern oklahoma
a small part of northwest texas

effective this wednesday night and thursday morning from 940 pm until 400 am cdt.

Hail to 2 inches in diameter...thunderstorm wind gusts to 70 mph...and dangerous lightning are possible in these areas.

The severe thunderstorm watch area is approximately along and 105 statute miles east and west of a line from 30 miles northwest of harrison arkansas to 35 miles west southwest of ardmore oklahoma.
For a complete depiction of the watch see the associated watch outline update (wous64 kwns wou8).

Remember...a severe thunderstorm watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes.

Other watch information...continue...ww 293...ww 295...ww 296...ww 297...

Discussion...a broken band of severe storms...with some embedded supercells...continues to develop swd/sewd along the cold front across ok. Despite the loss of daytime heating...strong instability and pronounced convergence/low-level frontogenesis will help maintain existing storms and support new development for the next several hours. Large hail can be expected with the strongest storms...while the damaging wind threat should increase some as a result of storm mergers/interactions and subsequent cold pool and small bow echo formation.

Venture, any possibility this could build into Canadian County? It's lightning here, and the power is flickering off and on. The wind is picking up too.

Yeah power is flickering here in Norman and it is a ways away. Lot of wind out there right now. It probably will keep back building.

Two metro area hail reports so far. 1.5" in Edmond and 0.88" in Nichols Hills.

Elevated rotation right now is at I-35 and I-44.

Okay that was way too close! I wasn't done bowling, but finished 3 games. Extremely heavy rain and I guess pea to dime size hail. The circulation they was reporting was just down the street from my apt, and over Luke's house. It went over mom's house as well. On the drive home (just got home now), heavy rain, poor visual, streets flooded, 44th flooded, the apt parking is flooded. Lightnings insane. Fuzzy the cat going berserk, I'm trying to type this. Amazing storm! I'm frickin soaked!

well.. looks to me like OKC proper's excitement for the day was really early this morning.

I take that back. Ohhh, do i take that back. . .:whiteflag

Looks like it's pretty much settled in the North part of the metro.. maybe Lake Thunderbird area might be affected... Franklin area Indian Hills Road.... but I think we're done. Goodnight. I hope!

Yeah, everywhere behind these storms should be quiet for the rest of the night. You can go to bed now, Karrie. You're safe.

Thanks for the updates, again!

I was thinkin, if the inflow to suddenly stop feeding the storms and they collaspe, we could see the top to surface jet stream and heat burst again, but that'd be so rare to happen 2 nights in a row. Would be amazing!

lol ... Spock

Thanks everyone for the updates.

I spent all evening cleaning up from Tuedays nights storm, finally got done around dark, came in to join in on the thread....and the flickering power knocked me offline......grrrrrr. Glad nothing touched down on the southside. I still hate the EAS warnings..dbl grrrrrr. Can you believe through all those stroms last night it didnt rain hard enough at our house to get the ground wet. So I'll have to water today. lol It was an awesone lightning show though.

Apparently Norman is in a time warp - LOL - but here is the PNS for today so far. Will also be keeping an update of information here: http://www.anvilcrawlers.com/index.php?title=May_13_2009

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE NORMAN OK
920 AM CDT THU MAY 15 2009

...DAMAGE SURVEYS TODAY...

METEOROLOGISTS ARE CONDUCTING DAMAGE SURVEYS TODAY TO INVESTIGATE
TORNADOES AND WIND DAMAGE THAT OCCURRED ON WEDNESDAY MAY 13TH.

SO FAR WE HAVE CONFIRMED A TORNADO THAT BEGAN ABOUT 9 MILES SOUTH OF
NARDIN AT 654PM AND ENDED AT 705PM. WE ALSO BELIEVE THERE WAS A
BRIEF LANDSPOUT TORNADO 1 MILE EAST OF FAY IN DEWEY COUNTY

WE WILL BE SURVEYING DAMAGE FROM GRACEMONT TO ANADARKO TO CADDO
COUNTY TO TRY TO DETERMINE THE CAUSE OF THE SUBSTANTIAL DAMAGE
THERE. PRELIMINARY ASSESSMENT OF DAMAGE REPORTS AND RADAR DATA
INDICATE MUCH OF THE DAMAGE MAY HAVE BEEN REAR FLANK DOWNDRAFT
WINDS...AND GIVEN THE COMPLEX STORM EVOLUTION THAT TOOK PLACE IT MAY
BE DIFFICULT TO DETERMINE DEFINITIVELY WHAT HAPPENED.

WE WILL LIKELY BE LOOKING AT DAMAGE AT LAKE STANLEY DRAPER WHERE
DAMAGE CONCIDES WITH AN IMPRESSIVE RADAR SIGNATURE THAT PROMPTED A
TORNADO WARNING FOR THE OKC METRO AREA.

WHILE A GROUND SURVEY IS NOT PLANNED FOR KAY AND NOBLE COUNTIES...WE
WILL BE COORDINATING CLOSELY WITH EMERGENCY MANAGEMENT TO GATHER
DETAILS ON DAMAGE TO HELP MAKE A DETERMINATION OF TORNADO INTENSITY.

WE WILL RELEASE INFORMATION AS SOON AS WE HAVE IT.

A little off topic but my Father in law is visiting next week and he is a weather buff.. are there any tours or anything that we can see related to weather at the Norman Weather Service facility or is it closed to the public?

Anyone know?

public information statement
national weather service norman ok
330 pm cdt thu may 14 2009

...preliminary damage survey results...

Here are the preliminary results of damage surveys conducted today
concerning the may 13th storms. This information may change as the
assessment continues.

Tornado - kay county ok - 9s nardin
654pm-705pm
this tornado developed over open country 9 miles south of nardin and
remained nearly stationary. No damage to structures has been
reported. The preliminary rating is ef0.

Tornado - dewey county ok - 1e fay
700pm-702pm
this brief tornado was observed by storm chasers and remained
over an open field. The preliminary rating is ef0.

Tornado - noble county ok - 2s billings to 4se billings
720pm-731pm
radar data and damage reports indicate the tornado moved east
southeast. Numerous trees and power lines were damaged. Based on
the available information...the preliminary rating for this tornado
is ef1.

Tornado - caddo county - near gracemont to anadarko
922pm-940pm
this tornado likely developed near gracemont and moved south along
and just east of highway 8. The most significant damage was noted
along country club road in anadarko where several homes had
significant damage. The preliminary rating for this tornado is
ef2...although this is subject to change pending further review of
data. Most of the damage in anadarko was likely the result of
straight line winds associated with a large rear flank downdraft.

Tornado - cleveland county - west side of lake stanley draper
1041pm-1047pm
this brief tornado developed on the northwest side of the lake and
moved south southeast along the western shore of the lake. A boat
dock was damaged and trees and other small structures were damaged.
Based on preliminary information...this tornado is rated ef0.

If you have images...video or other information related to the may
13th storms...contact the nws in norman at 405-325-3816.

Is there someplace on the net where I could find a radar loop of the area of rotation that caused the issuance of the tornado warning for OK County last night? Specifically, I'm interested in it as it moved through the Mid-Del area. We had a very difficult time following the activity on TV as a result of frequent power outages interrupting the coverage.

This is the only site I know of, but you may need another application to view the data:

NCDC: Radar Data (http://lwf.ncdc.noaa.gov/oa/radar/radardata.html)

Thank you.

I'll give it a try. It looks like they use UTC and if I've calculated correctly (which is not necessarily likely), I need the period between about 0100 and 0300 5/14/09 UTC, the data for which is not yet available. I'll order the data, download the visualizer software and see what happens.

I'll get myself prepared now for the LOST season finale to not be aired in HD...

Season Finale Of 'Lost' To Be Re-Aired
Set DVRs For 10:39 P.M. Saturday To 12:39 A.M. Sunday

The two-hour season finale of LOST will re-air Saturday night, it was announced on Thursday.


DVRs should be set for 10:39 p.m. Saturday until 12:39 a.m. Sunday.

The finale will be shown in its entirety.

Making some new storm data pages on AC...here is for yesterday:

May 13 2009 - AnvilCrawlers (http://www.anvilcrawlers.com/index.php?title=May_13_2009)

Also trying to fill out more content on the site. Invite everyone to come over and help. Trying to make the site be a wealth of information for everyone novices and those that understand the more complex data. Will be working on incorporating additional information like "How To's" so if you really want to know how to read an upper air sounding, it walks you though and you know what numbers to look for and what they mean.

Thanks Venture!

Well considering I don't have a DVR, looks like I won't be going out on Saturday night. MONEY SAVER!!!! Thanks KOCO ;-)

go to ABC.com then to free episodes and you will find the answers you seek.

Is the tours free?

I watched the last part on ABC.com last night

Spoiler alert....there is a complete idiot in this video.

CNN has been showing the short version of this vid on their I-reports all morning. What they dont show you is what an idiot this guy is......I like to call guys like him "yahoos". I hesitated to post this because I didnt want to give him any publicity. I was going to post the version on youtube yesterday but it was removed by Mr. Ambrosia because he was getting to many negative comments. And rightly so. He gives serious storm chasers and spotters a bad reputation. Anyhow....here it is. My idiot of the day award goes to Micheal Ambrosia....who does it just for the thrills and money. I hope the police see this and take away his drivers license. Like I said I hesitated to post this yesterday because of the publicity....I guess since hes all over CNN now its too late....so here it is. Notice hes not only speeding and driving recklessly, but filming with his "free hand" at 100+ mph.

LiveLeak.com - Amature Video; Close Encounter With Tornado May 13/09 (http://www.liveleak.com/view?i=3a4_1242319398&c=1)

Reading some of the comments on ST, it is pretty clear...the old days of chasing are gone. I didn't start chasing on the plains until the mid to late 90s, but chasing them and now are so vastly different. The population of "chasers" has soared a ton and everyone is out there with their toys. While I can't say I didn't have my share, I never went over the edge with decals, lightbars, or a mobile weather station on my car. I was out there to see if I could nail the forecast, pick the right place, and enjoy the structure and power of mother nature.

Today? These yahoos are out there with no care for anyone else's life. They are wanting to get the close up video so they can make some money and get their name on the news.

The speeds topping 120-130mph are just effin stupid. On wet roads, with traffic, on a two lane highway. These are the people you would not mind seeing wrapped around a telephone pole before they hurt or kill someone else.

I hope the authorities do more than just take away his license. This was nothing more than a publicity stunt. I believe this is him as well: Ambrosia ?acting? on desire to serve in the Missouri National Guards (http://www.whiteman.af.mil/news/story.asp?id=123083363)

Notice...he is an actor who is probably out of work. How best to get a job then plaster your face all over the media, even if it was doing something stupid. I'm sorry. No responsible chaser in their right mind would be going that fast on a wet road while video taping with one hand in traffic.

Oh these people just get me so PO'd at what they are doing to the community. Morons like this reduce the public perception of the chasing community and then local law enforcement starts losing trust in what the responsible ones do. 7-8 years ago you could be on the side of the road and a officer would come over to chat and ask about the weather. Now, you are more likely going to get ticketed or harassed.

sheesh, that was brutal. What was he thinking ???

Thanks Venture 79.

My data order was delivered and using their NOAA Climate Toolkit, I was able to develop a radar loop movie. What actually happened made a whole lot more sense after watching it.
