Severe Weather Outlook - May 12 & 13th

[venture]

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.

[venture]

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

[Karried]

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

[venture]

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

[venture]

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.

Urgent - immediate broadcast requested
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.

[Jon27]

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.

[venture]

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.

[venture]

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

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!

[jstanthrnme]

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. . .

[Karried]

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!

[Thunder]

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

[jstanthrnme]

For Venture:

Thanks for the updates, again!

[Thunder]

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!

[Karried]

lol ... Spock

Thanks everyone for the updates.

[westsidesooner]

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.

[venture]

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.p...le=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.

[Karried]

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?
