areas affected...portions wrn/nrn ok...central/ern ks.

Concerning...tornado watch 183...

Valid 260258z - 260430z

the severe weather threat for tornado watch 183 continues.

Several supercells still evident within ww area...with mixed trends in both storm intensity and environmental parameters. Potentially tornadic supercell noted invof enid...strengthening storm is entering srn major county. Meanwhile steady to decreasing supercells are evident near and s of i-40 over wrn ok and within messy storm modes over s-central/sern ks.

Over ww area in general...tornado potential may have peaked...but cannot be considered finished yet. Diabatic sfc cooling is leading to increased mlcinh -- estimated at 50-100 j/kg attm over most of ww area based on modified raobs and ruc soundings. However...effective lifted parcels remain rooted at or very near sfc...and strengthening llj continues to enlarge low level hodographs...keeping 0-1 km srh 250-450 j/kg for any intense/rotating updrafts that can tap favorably moist air mass within that layer. Ww is scheduled to expire at 04z...but portions of this region may require additional ww issuance before then.

Farther n...across central/nrn ks...those portions of 40-50 kt llj that are moving around ok/srn ks convection will supply favorable moisture...within stg/elevated waa regime. Elevated mucape 1000-1500 j/kg with 30-40 kt effective shear will be favorable for large hail with most intense tstms.

Three areas of interest right now. The one tornado warned rotation by Enid. Another is just east of Longdale, and a third is SW of Watonga.

[venture]

3D Radar Imagery of the current tornado that is now confirmed in Enid. What you are seeing are is the rotation in the storm actually mixing down, not the funnel itself. Just to clarify. : )

[jstanthrnme]

Wow! very cool image!

[venture]

Enid storm has some of the rotation extending down still, but definitely not mixing down as much as it did earlier.

Fairview storm has some rotation in it as well, not as tight or well defined as the one by Enid.

[venture]

DISCUSSION...ENVIRONMENT WILL BE CHARACTERIZED BY LARGE LOW LEVEL
HODOGRAPHS/SRH AND PRESENCE OF ROTATING UPDRAFTS ABOVE FAVORABLE
BOUNDARY LAYER THETAE. TORNADO POTENTIAL EXPECTED TO CONTINUE FOR A
FEW MORE HOURS UNTIL AIR MASS STABILIZES TOO MUCH FOR SFC-BASED
EFFECTIVE INFLOW PARCELS...INVOF SFC BAROCLINIC ZONE.

Kool graphics, Venture.

I did came home, sat down, waited for the weather edition then suddenly a Tornado Warning near Enid. Mike Bennet and the Emergency Managers confirmed the tornado on the ground and there was extensive home damages.

Other news in the spotlight, I kept checking News 9, but it seem that Gary England was sleeping at the desk.

[venture]

Quick update...Kremlin area has a confirmed tornado on the ground still, this is the Enid storm. Damage is reported with the storm in Enid.

New intensifying circulation by Orion to the Southwest of Fairview moving NE.

Another not as organized area of rotation is north of Isabella to the SW of Ringwood. This is all west of Enid.

Storms are moving into the area of better helicity / shear, so this is why we are likely seeing tornado production finally taking place.

I really like these threads Venture, thanks again for all of the great information. Like Luke said, its kind of a behind the scenes look at meteorology. Your information is as good/better than the heads on tv.

Though I almost feel the need to have a glossary handy to figure out some of the terms and abbreviations, its more objective than what Gary, Rick, or Mike have to say, and that is the reason I like to keep up with these threads.

I'll definately be checking in tommorow.

[venture]

If I spit anything out that is a term that I don't explain, just ask. : ) I try to notate what the abbreviation is in the same post or earlier post before I use it again.

[OKCisOK4me]

Wowzers Venture! If they had those kind of graphics on TV, I'd imagine the average Oklahoman might be interested in the long track coverage on TV!

[jstanthrnme]

In the context of your posts, I can pretty much get it figured out.

Really, I wouldn't want to distract you, because what you do, is awesome.

[Karried]

I agree.. I'll come here to find out the severe weather forecast before anywhere else.. it's always spot on.. thanks for your hard work Venture.

Waiting for the new Day 1 to come out before I head to bed. Long day.

[venture]

I was thinking of just heading to bed, but then realized what time it was and what is another 35 minutes.

Truely is amazing to have tornadoes still going on. Gives us all an idea of what is in store for tomorrow to come. I still think it will be worse.

[Nermel]

Val had a damage path to urgently announce on the air. Jed had to remind him that was from a prior tornado. Dumbass.
