NWS STORM PREDICTION CENTER NORMAN OK
0441 PM CDT WED MAY 07 2014

AREAS AFFECTED...NRN AND CNTRL OK...SCNTRL KS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 123...

VALID 072141Z - 072245Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...AN ISOLATED SEVERE THREAT MAY DEVELOP OVER THE NEXT FEW
HOURS ACROSS NRN OK AND SCNTRL KS. LARGE HAIL AND WIND DAMAGE WILL
BE THE PRIMARY THREATS WITH THE ACTIVITY. AN EXTENSION OF WW 123 TO
INCLUDE PARTS OF NW OK MAY BE NEEDED. IN ADDITION...WW ISSUANCE MAY
BECOME NECESSARY TO THE NORTH OF WW 123 ACROSS PARTS OF SCNTRL KS.

DISCUSSION...THE LATEST SFC ANALYSIS SHOWS A SHARPLY DEFINED DRYLINE
EXTENDING NNEWD FROM NW TX ACROSS WRN OK INTO SRN KS. NUMEROUS
THUNDERSTORMS ARE DEVELOPING ALONG AND JUST TO THE EAST OF THE
DRYLINE. THESE STORMS HAVE ACCESS TO STRONG INSTABILITY ACROSS MUCH
OF WRN OK WHERE MLCAPE IS ESTIMATED IN THE 2000 TO 3500 J/KG RANGE.
IN ADDITION...THE FREDERICK OK WSR-88D VWP SHOWS A GRADUALLY VEERING
WIND PROFILE WITH HEIGHT AND A NEARLY UNIDIRECTIONAL WIND PROFILE IN
THE LOWEST 2 KM. THIS SHOULD BE FAVORABLE FOR SPLITTING CELLS. THE
LATEST WRF-HRRR CONFIRMS THIS BY MOVING A COUPLE OF LIFT SPLIT
SUPERCELLS NNEWD INTO SCNTRL KS OVER THE NEXT FEW HOURS. THE STRONG
INSTABILITY IS CONTRIBUTING TO STEEP MID-LEVEL LAPSE RATES OF 8.0 TO
8.5 C/KM WHICH WILL BE FAVORABLE FOR LARGE HAIL WITH THE MORE
INTENSE UPDRAFTS. ALSO...LARGE SFC TEMP-DEWPOINT SPREADS OF 25 TO 35
DEGREES SHOULD HELP ACCELERATE DOWNDRAFT SPEEDS MAKING WIND DAMAGE A
POSSIBILITY AS WELL.

AREAS AFFECTED...NCNTRL TX...CNTRL OK

CONCERNING...SEVERE THUNDERSTORM WATCH 123...

VALID 072326Z - 080030Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 123
CONTINUES.

SUMMARY...A THREAT FOR ISOLATED LARGE HAIL...WIND DAMAGE AND PERHAPS
A TORNADO WILL CONTINUE OVER THE NEXT FEW HOURS ACROSS WRN OK AND NW
TX. THE THREAT MAY EXPAND EWD INTO CNTRL OK AND NCNTRL TX. WW
ISSUANCE MAY BECOME NECESSARY TO THE EAST OF WW 123.

DISCUSSION...THE LATEST WSR-88D RADAR DATA SHOWS SEVERAL SUPERCELLS
LOCATED JUST TO THE EAST OF THE DRYLINE FROM JUST TO THE EAST OF
VERNON TX EXTENDING NWD TO NEAR WEATHERFORD OK. ONE RIGHT-MOVING
SUPERCELL EXHIBITING STRONG ROTATION IS LOCATED TO THE SOUTHEAST OF
WICHITA FALLS. THE LATEST WRF-HRRR SUGGESTS THE ACTIVITY WILL
GRADUALLY MOVE NEWD ACROSS CNTRL OK EXTENDING SWD TO THE RED RIVER
NORTH OF FORT WORTH TX. SFC DEWPOINTS ALONG THIS CORRIDOR ARE IN THE
MID 60S F WHICH IS CONTRIBUTING TO MODERATE INSTABILITY. IN
ADDITION...REGIONAL WSR-88D VWPS SHOW GRADUALLY VEERING WIND
PROFILES IN THE LOW TO MID-LEVELS WITH 0-6 KM SHEAR OF 35 TO 40 KT.
THIS COMBINED WITH MID-LEVEL LAPSE RATES AROUND 8.0 C/KM SHOULD BE
FAVORABLE FOR ISOLATED LARGE HAIL WITH THE MORE INTENSE ROTATING
CELLS. THE MORE DOMINANT CELL SOUTHEAST OF WICHITA FALLS MAY PRODUCE
A TORNADO OVER THE NEXT HOUR BUT CAPPING TO THE EAST OF THE CELL MAY
MAKE THE THREAT SHORT-LIVED. FURTHER TO THE NORTH IN SCNTRL
OK...CELL MERGERS SHOULD MAKE WIND DAMAGE A POSSIBILITY WITH THE
MORE ORGANIZED CELL CLUSTERS.

Uhh.. There's a pretty clear hook on the radar on kfor to the west of Moore. Should this be a concern?

[bchris02]

Looks like we are going to get a real good rain out of this. We are under a flash flood warning right now.

Yeah, there is a rotating hook just west of Moore.

[bchris02]

Is the north metro pretty safe from damaging hail at the moment?

[Anonymous.]

Flash flooding downtown. Thunder exit is a mess!


But damn this is the rain we've been waiting for!

[Dustin]

It is raining cats and dogs in The Village!

Is Village Drive under 3 feet of water yet?

[Ginkasa]

Uhh.. There's a pretty clear hook on the radar on kfor to the west of Moore. Should this be a concern?

Yeah, I flipped over to the TV just to see how it was going and that was the first thing I saw. I stressed a little while pulling up the forum.
