Isolated chances next couple days until stronger system moves in early-mid week. Currently boundary moving into Central OK which some developing CU along it. There is a chance for a storms to develop later this afternoon along this which might get close to severe levels with either strong winds or marginally severe hail.

Developing storm now in NW Oklahoma County and far SW Logan County. Main area centered at Waterloo & Highway 74. Movement will be SE should it continue to develop.

Update: 418PM - updraft failed to get established and fell apart. Add'l development remains possible through the afternoon/evening along the boundary.

Storms exploding and moving thru the metro again early morning hours. Twice in a row. Just saw a flash, so checked the radar. Nice storms.

WINDS SHOULD EXIST HELPING TO REINFORCE A VERY MOIST AIRMASS WITH

PLAINS. THE MODELS ARE NOW IN MUCH BETTER AGREEMENT FOR WEDNESDAY
DEVELOPING A LARGE AREA OF MODERATE TO STRONG INSTABILITY FROM THE
TX AND OK PANHANDLES ESEWD ACROSS OK INTO THE SRN OZARKS. ELEVATED
THUNDERSTORM ACTIVITY MAY BE ONGOING DURING THE MORNING NEAR THE
COLD FRONT IN THE CNTRL HIGH PLAINS OR IN THE SRN HIGH PLAINS WHERE
A LOW-LEVEL JET IS FORECAST TO BE LOCATED.

ALTHOUGH MODEL SOLUTIONS VARY SIGNIFICANTLY CONCERNING THUNDERSTORM
DEVELOPMENT WEDNESDAY AFTERNOON...ONE PLAUSIBLE SCENARIO WOULD BE
FOR INITIATION OF SFC-BASED CONVECTION TO OCCUR ALONG THE NWRN EDGE
OF THE STRONGER INSTABILITY BY LATE AFTERNOON IN SERN CO...SW KS OR
THE OK/TX PANHANDLES WITH AN MCS ORGANIZING AND MOVING ESEWD ACROSS
THE REGION. THIS IDEA IS SUPPORTED BY THE NAM AND GFS SOLUTIONS
WHICH STRENGTHEN A WELL-DEFINED 30-40 KT LOW-LEVEL JET ACROSS THE
SRN PLAINS BY EARLY EVENING. SUBSTANTIAL LOW-LEVEL FLOW AND
INCREASING FLOW ALOFT SHOULD CREATE MODERATE TO STRONG VERTICAL
SHEAR PROFILES SUFFICIENT FOR AT LEAST ISOLATED SEVERE STORMS AND
POSSIBLY SOME SUPERCELLS. FORECAST SOUNDINGS ACROSS THE REGION SHOW
STEEP MID-LEVEL LAPSE RATES FAVORABLE FOR ISOLATED LARGE HAIL. AN
INCREASING WIND DAMAGE THREAT COULD ALSO EXIST IF AN MCS CAN BECOME
WELL-DEVELOPED AND PERSIST INTO THE EVENING. AN UPGRADE IN SEVERE
PROBABILITIES MAY BE NECESSARY ACROSS THE REGION ONCE MODEL
SOLUTIONS BECOME IN BETTER AGREEMENT AND CERTAINTY INCREASES.

THUNDERSTORMS WILL ALSO LIKELY DEVELOP DURING THE AFTERNOON ALONG
THE COLD FRONT MOVING SEWD ACROSS CNTRL AND SRN NEB INTO NRN KS.
MARGINALLY SEVERE WIND GUSTS AND HAIL WILL BE POSSIBLE DURING THE

COMPLEX FORECAST EXISTS WED/WED NIGHT OWING TO POTENTIAL FOR
EPISODIC STRONG/SEVERE TSTM DEVELOPMENT FOCUSED ALONG BOTH SYNOPTIC

APPEARS THAT THE GREATEST SEVERE WEATHER THREAT WILL EXIST OVER THE
CNTRL/SRN HIGH PLAINS FROM COLD FRONT SEWD ALONG WRN EXTENSION OF
STATIONARY BOUNDARY WED AFTERNOON INTO NIGHT. HERE...BOUNDARY LAYER
DEWPOINTS IN THE 50S TO LOW/MID 60S WILL COMBINE WITH ERN EXTENSION
OF EML/STEEP MIDLEVEL LAPSE RATES AND DAYTIME HEATING TO YIELD A
MODERATELY UNSTABLE AIR MASS WITH MLCAPE APPROACHING 1500-2500
J/KG.

FRONTAL ASCENT...OROGRAPHIC FORCING AND INCREASED HEIGHT FALLS
ASSOCIATED WITH MIDLEVEL TROUGH ALL WILL CONTRIBUTE TO AN INCREASE
IN TSTM COVERAGE AND INTENSITY THROUGH THE DIURNAL HEATING CYCLE
FROM ERN CO/WRN KS SWD/SEWD THROUGH NERN NM...THE TX/OK PNHDLS INTO
WRN OK. MID/HIGH-LEVEL WIND FIELDS ARE FORECAST TO BACK/INCREASE
WITH APPROACH OF SHORT WAVE TROUGH WITH VERTICAL SHEAR BECOMING
SUFFICIENT FOR SUPERCELLS CAPABLE OF MAINLY DAMAGING WINDS AND LARGE
HAIL. SOME THREAT FOR TORNADOES WILL EXIST WITH ANY SUPERCELLS
INTERACTING WITH QUASI-STATIONARY SYNOPTIC BOUNDARY OR ANY

0314 pm cdt tue jul 28 2009

areas affected...srn ks/nrn ok

concerning...severe potential...watch likely

valid 282014z - 282115z

ww will likely be needed for parts of south central ks into nrn ok where moderate instability and recent increase in effective bulk shear /30-35 kt/ suggests potential for storms to become severe.

Regional radars indicated tstms increasing in coverage/intensity from central/srn ks enewd through central mo in the vicinity of a surface boundary across these states. An additional storm or two were developing across nrn ok. The weakening of surface based cinh during peak heating and forcing for ascent attendant to a short wave trough moving through ern ks into the lower mo valley will support additional storm development. 15z namkf suggested strongest effective bulk shear for storm organization should remain across srn ks/nrn ok with potential for activity to produce hail and strong wind gusts.

Farther e into mo...weak deep layer shear will tend to limit storm organization...but locally strong wind gusts and marginally severe hail will be possible into the early evening given the degree of available instability.

It looks like the NWS and SPC have moved their target for any MCS's this evening a little further south and west over extreme western Ok and the panhandles. Only one model that I can see still puts central Ok in the mix tonight. Whats your thoughts Venture?

Nasty outflow boundaries everywhere. :LolLolLol

Yeah models are definitely split on what happens today. Looks like NSSL WRF and the GFS are maintaining an MCS moving across the body of Oklahoma. While the majority of the others keep everything out west in the panhandles or at the most SW Oklahoma. We'll see what happens. I think we'll get the typical daytime development today with the boundaries around from yesterday's storms...and who knows, maybe the MCS will track more east than expected. Granted that usually never happens though. LOL

Do you know what the wind speeds were last night in the Midwest City area?

Around 50mph? Quite a bit of customers lost power in Edmond and MWC.

Heres a couple of pics I took as the first round of storms came through between 5:30 and 6 pm.. They are all of the back (westside) of the storm that formed near deer creek then moved southeast before dieing over OKC.

I don't see any sense in replacing your roof unless it's leaking. So what if another big hail storm pounds your new shingles next week? See if the insurance company will replace it, too? My roof is only about 5 years old and still looks fine to me after hail storms nearly every year, even though the hail was bigger this year. And a man experienced in roofing looked at it last year and couldn't see hail damage.

Last night, the thunder was so loud, it set off all of the house alarms! This weather is crazy!

There hadnt been any lightning or thunder for hours at our house last night and I was watching tv with the curtains closed and saw a huge Orange flash outside. So I expected thunder immedeately. I waited 8 seconds (actually counted) before one of the loudest booms I've ever heard. (It set off car and home alarms in our neighborhood). I was confused by the delay between the bright flash and the boom (surely a flash that bright was very close I thought) and for a brief moment terror crept into my mind. I thought there had been a huge explosion. I raced to the door as the second and third booms occured. And only when I stepped outside did I realize it was just thunder.

I love storms and I've probably sat out on the porch 500 times watching and listening to them as they roll past. Or jumped in the truck to chase after and photograph them. So I'm accustomed to the sound. Only a couple of times have I seen/heard lightning and thunder like the bolts last night. There were several bolts like that last night where you could hear a series of booms rolling across the sky like they were several bombs on one fuse. Maybe Venture has an explanation. The thick humidity...or extra voltage???

It scared the crap outta the pets....

....(snip)....It scared the crap outta the pets....

Now that's an entirely different kind of, ahem, storm damage....

Did it rain in the metro around noon? I was surprised when mom and I went to Harrah to see the Ragdoll kittens, she was telling me that she almost went to visit her parents when she saw dark clouds, she changed her mind then it downpoured.

The last night storm and another previous storm, I saw lightnings that streaked across the clouds (bunch of lines). It was amazing and I do not remember when the last time I have ever seen it. Usually I see cloud to ground lightning and lightning behind the clouds, but rarely do I see all those crazy lines under the clouds.

Karrie, unless your roof have serious leak damage, then there is no need for a complete new roof. I can see some wear/tear on mom's roof, but it is still in great shape and no leak. Only repair she had was during the ice storm a portion of her pecan tree made a small hole. You can not keep it perfect.

Venture, I hope you were up last night. It was a huge complex.

I was at 50th and Lincoln at noon today (mmmm...Bedlam BBQ) and just after I got inside, it started pouring. By the time I finished eating, it had stopped.

Ahh, must be a stray storm trying to catch up with the monster. :LolLolLol

I don't see any sense in replacing your roof unless it's leaking.



I want to take care of it before that happens! lol

Our roof is much older than yours and it is totalled.
I've never filed an insurance claim in my life but I've paid out thousands upon thousands of dollars during that time.

The insurance adjuster and the roofing coming agreed our roof was totalled... It might have been we just happened to be under a severe hail core. The hail was huge (I posted pics somewhere around here).... it took off the little granules on the shingles .. our gutter was full of them.. that weakens the integrity of the roof.

In that case, if the insurance company raises the rates, then you will need to fight to lower the rates back to where it was.
