Oklahoma Weather Discussion - February/March 2013

[venture]

The SVR warned cell moving into OKC has slight rotation, this will increase the hail sizes. Quarters were reported in Chickasha.

Looking at the mPING map, dimes mainly over SW OKC and NW Moore. Everything is moving east now. The cells that moved over Norman have ticked up a bit, but I don't it'll make much of an impact on the lake. Most of the ground here is already dry.

A friend texted me and said she was getting hail in S OKC

Slight Risk area was expanded at 11AM and forgot to repost. Runs roughly west of a line from Woodward to Edmond to Ada to Denton TX.

...SRN PLNS TODAY INTO TNGT...
WAA AND MOISTURE TRANSPORT ATOP FAIRLY STOUT EML CAP LIKELY WILL
CONTINUE TO SUPPORT AREAS OF HIGH-BASED AND ELEVATED STORMS ABOVE
THE CAP INTO TNGT...BOTH IN DEVELOPING WARM SECTOR OVER OK AND NW
TX...AND ATOP DEVELOPING SFC WARM/STNRY FRONT ACROSS THE SRN/CNTRL
OZARKS. SOME OF THIS ACTIVITY MAY YIELD MARGINALLY SVR HAIL. BUT
MOST OF THE STORMS SHOULD REMAIN ROOTED ABOVE THE CAP. COUPLED WITH
RELATIVELY MODEST SHEAR...DEGREE OF ELEVATED CAPE SHOULD REMAIN TOO
LIMITED TO POSE AN APPRECIABLE RISK FOR SVR WEATHER.

A SOMEWHAT GREATER RISK FOR SVR STORMS...MAINLY WITH HAIL BUT ALSO
POSSIBLY WITH LOCALLY DMGG WIND...MAY EVOLVE LATER THIS AFTN INTO
TNGT OVER PARTS OF WRN AND NW TX AND ADJACENT WRN/SRN OK. IN THIS
REGION...FAVORABLY-TIMED APPROACH OF NM UPR IMPULSE WITH MAX SFC
HEATING MAY YIELD A SUFFICIENT COMBINATION OF DESTABILIZATION AND
ASCENT TO PROMOTE STRONG STORM DEVELOPMENT ON WRN FRINGE OF LOW-LVL
MOISTURE RETURN.

WHILE WLY DEEP SHEAR ACROSS REGION WILL REMAIN SEASONABLY MODEST
/30-35 KTS/...UNIDIRECTIONAL NATURE OF CLOUD-LAYER FLOW AND PRESENCE
OF DEEP EML/STEEP MID-LVL LAPSE RATES COULD YIELD NUMEROUS STORMS
WITH SVR HAIL AS MUCAPE INCREASES TO NEAR 1500 J/KG. CONTINUED EWD
MOTION OF UPR IMPULSE AND EXPECTED AMALGAMATION OF STORM-GENERATED
COLD POOLS MAY LEAD TO THE DEVELOPMENT OF ONE OR TWO ESE-MOVING
STORM CLUSTERS OVER NW TX AND OK. THIS ACTIVITY COULD PRODUCE
ADDITIONAL SVR HAIL AND LOCALLY DMGG WIND INTO LATER TNGT...BEFORE
DIURNAL COOLING WEAKENS UPDRAFT STRENGTH.

New Day 2 Outlook is out and follows along with my thoughts last night of a high end slight risk event. 30% hatched area now in place for much of South central Oklahoma in the area along and south of I-40 and between McAlester on the East to Altus on the West sides.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1229 PM CDT FRI MAR 29 2013

VALID 301200Z - 311200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN AND
CNTRL PLAINS...

...SRN AND CNTRL PLAINS...
NORTHWEST FLOW WILL REMAIN IN PLACE ACROSS THE GREAT PLAINS FROM
TONIGHT INTO SATURDAY AS AN UPPER-LEVEL TROUGH AMPLIFIES SEWD INTO
THE UPPER MS VALLEY AND MID-MO VALLEY. AT THE SFC ON SATURDAY...A
LOW PRESSURE AREA IS FORECAST TO MOVE EWD ACROSS SRN IA AND NRN MO
WITH A COLD FRONT ADVANCING SEWD INTO ERN KS AND NW MO BY AFTERNOON.
THE SRN PART OF THE FRONT EXTENDING FROM NW OK SWWD INTO WEST TX IS
EXPECTED TO MOVE SLOWLY SEWD. THE SFC LOW AND FRONTAL BOUNDARY
SHOULD BE A FOCUS FOR CONVECTIVE DEVELOPMENT DURING THE DAY.
SCATTERED THUNDERSTORMS MAY BE ONGOING AT THE START OF THE PERIOD
NEAR THE SFC LOW IN THE MID-MO VALLEY WITH CONVECTIVE INITIATION
TAKING PLACE IN THE SRN PLAINS LATE SATURDAY AFTERNOON AS A CAPPING
INVERSION WEAKENS. THE MODELS ARE IN RELATIVELY GOOD AGREEMENT THAT
A CLUSTER OF THUNDERSTORMS WILL ORGANIZE ACROSS THE RED RIVER VALLEY
OF SRN OK AND NORTH TX DURING THE EARLY EVENING WHERE LOW-LEVEL FLOW
SHOULD BECOME ENHANCED.

FORECAST SOUNDINGS ALONG THE INSTABILITY AXIS AT 21Z SHOW SFC
DEWPOINTS RANGING FROM THE UPPER 50S F IN SE KS TO THE LOWER 60S F
AROUND WICHITA FALLS TX. MLCAPE VALUES ARE FORECAST TO REACH 1500 TO
2000 J/KG IN SE KS AND NE OK WITH HIGHER VALUES OF 3000 TO 3500 J/KG
POSSIBLE SWWD INTO SW OK AND NORTH TX. IN ADDITION...0-6 KM SHEAR
VALUES ARE FORECAST TO RANGE FROM AROUND 50 KT IN NE OK TO AROUND 40
KT NEAR THE RED RIVER. THIS ENVIRONMENT ALONG WITH 850 TO 500 MB
LAPSE RATES AROUND 8.0 C/KM SHOULD BE SUFFICIENT FOR SUPERCELL
DEVELOPMENT ESPECIALLY WITH CELLS THAT REMAIN DISCRETE. THE STEEP
LAPSE RATES AND COLD TEMPS ALOFT SHOULD BE FAVORABLE FOR LARGE HAIL
WITH ISOLATED VERY LARGE HAIL POSSIBLE ESPECIALLY IF STRONG
INSTABILITY IS REALIZED IN THE RED RIVER VALLEY. A POTENTIAL FOR
TORNADOES MAY ALSO DEVELOP BUT THE RELATIVELY WEAK FLOW BELOW 850 MB
COULD BE A LIMITING FACTOR. IF THE FAVORED MODE BECOMES LINEAR
DURING THE EARLY EVENING...THEN AN ISOLATED WIND DAMAGE THREAT MAY
ALSO DEVELOP. THUNDERSTORMS MAY PERSIST INTO THE OVERNIGHT PERIOD
ACROSS THE OZARKS EXTENDING SWWD INTO CNTRL TX BUT THE SEVERE THREAT
SHOULD BECOME INCREASINGLY MARGINAL AS INSTABILITY WEAKENS DURING
THE LATE EVENING AND OVERNIGHT PERIOD.

AREAS AFFECTED...PORTIONS OF THE TX PANHANDLE/SOUTH PLAINS...NWRN TX
AND SWRN OK

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 292022Z - 292245Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...WIDELY SCTD SVR TSTMS WITH LARGE HAIL AND DAMAGING WINDS
MAY DEVELOP AFTER 2030Z. A WW MAY BE NEEDED PRIOR TO 22Z.

DISCUSSION...FORCING FOR ASCENT ASSOCIATED WITH AN UPPER LEVEL
IMPULSE MOVING INTO W TX WILL OVERSPREAD A MODERATELY UNSTABLE AIR
MASS EAST OF A SHARPENING SFC DRYLINE THROUGH LATE AFTN. BY
22Z...THE DRYLINE SHOULD EXTEND SWD FROM A WEAK SFC LOW OVER THE SRN
TX PANHANDLE S/SWWD INTO THE TRANS-PECOS REGION. LATEST VISIBLE
IMAGERY SUGGESTS SOME INCREASE IN CU FIELD NEAR THE CAPROCK TO THE
SW OF CDS. CONTINUED DAYTIME HEATING AND FORCING FOR ASCENT SHOULD
REDUCE CIN SUFFICIENTLY FOR WIDELY SCTD TSTM DEVELOPMENT AFT 2030Z.
WITH STEEP MID-LEVEL LAPSE RATES /8-8.5 DEG C/KM/ AND DEEP-LAYER
SHEAR OF 35-40 KT...ENVIRONMENT WILL BE FAVORABLE FOR LARGE HAIL AND
DAMAGING WINDS. ONE OR MORE ESEWD-MOVING CLUSTERS OF STORMS MAY
EVENTUALLY DEVELOP OVER TIME INTO EARLY EVENING WITH PRIMARILY A
THREAT FOR DAMAGING WINDS.

It's been in the Metro for awhile. Some day I'm giving geography lessons. Sigh.

Anyway. Northern storm split again, with two severe storms moving NE.

I should have said the only parts of the metro I give a damn about lol

[Bunty]

Thunderstorm development over Stillwater has finally led to light to moderate rain falling, but nothing severe, so far. As another storm is active in Logan County, where there is a severe storm warning until 8:15pm, it will be interesting to see if a severe storm warming will be issued for Payne County.

[Bunty]

And so to little surprise a severe thunderstorm warning has been issued for Payne County until 9pm.

AREAS AFFECTED...NW/N-CNTRL TX...SRN OK

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 300224Z - 300400Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...SOME UPSCALE GROWTH IN CONVECTION HAS BEEN NOTED ACROSS NW
TX NEAR THE RED RIVER. IF THIS TREND CONTINUES...NEW WW ISSUANCE
WILL BE POSSIBLE IN THIS AREA AS THE STORM COMPLEX BEGINS TO MOVE
OUT OF WW 64.

DISCUSSION...A CLUSTER OF STORMS ACROSS NW TX NEAR THE RED RIVER HAS
SHOWN A RECENT UPTICK IN ORGANIZATION AND INTENSITY. AN INCREASING
LOWLEVEL JET /30-35 KTS AT 1 KM IN RECENT FWD VAD DATA/ WILL LIKELY
HELP TO SUSTAIN THIS ACTIVITY FOR MUCH OF THE EVENING. MODERATE
INSTABILITY WILL CONTINUE TO SUPPORT A LARGE HAIL THREAT...BUT WITH
INCREASINGLY LINEAR MODE AND ACCELERATING FORWARD SPEED...AN
INCREASE IN SEVERE WIND THREAT IS ALSO POSSIBLE. THE MAIN
UNCERTAINTY AT THIS TIME IS THE COOLING BOUNDARY LAYER AND
INCREASING CAP STRENGTH...WHICH WILL BECOME INCREASINGLY UNFAVORABLE
FOR MAINTENANCE OF NEAR-SFC BASED STORMS AND SEVERE WIND.

MEANWHILE...A LONG-LIVED SUPERCELL IN CLAY COUNTY TX CONTINUES TO BE
A SEVERE HAIL THREAT. IF THIS STORM IS ABLE TO PERSIST...IT MAY
EVENTUALLY BE ABSORBED BY FASTER-MOVING CLUSTER TO THE WEST. WW 64
HAS BEEN LOCALLY EXTENDED INTO JEFFERSON AND LOVE COUNTY OK TO COVER
THE SHORT-TERM RISK FROM THIS STORM.

IF THE CURRENT TREND CONTINUES AND CONVECTION NEAR THE RED RIVER
CONTINUES TO BECOME MORE ORGANIZED...NEW WW ISSUANCE WILL BE
POSSIBLE BETWEEN 03-04Z.

OTHER WATCH INFORMATION...CONTINUE...WW 64...

DISCUSSION...PRIMARY SEVERE THREAT WILL LIKELY BE ASSOCIATED WITH A
SMALL BUT WELL-ORGANIZED/ACCELERATING MCS ACROSS EXTREME SOUTHERN OK
AND NORTH-CENTRAL TX. ALTHOUGH BOUNDARY LAYER CINH WILL NOCTURNALLY
INCREASE...SUSTENANCE OF THE MCS WILL BE AIDED BY A MODEST LOW LEVEL
JET /30 KT PER FORT WORTH WSR-88D VWP/ AND MOIST/UNSTABLE INFLOW
ABOVE THE SURFACE. BOUTS OF DAMAGING WINDS/SEVERE HAIL WILL REMAIN A
CONCERN INTO THE OVERNIGHT.
