Impressive looking cell in SW OK.

[6SpeedTA95]

Hey 65SpeedTA95 where is your 3:30PM location? Be safe out there........no doubt will be some very intense supercells later the day. I keep checking out IP Cam at one of our plants near Pampa, Texas. So far the storms have NE and E of that area and the Cams point to the West.

Thats a good question, we're not 100% sure at this point, our plan is to be in enid by 3pm or 3:15 re evaluate based on new data. We may wind up heading west out of Enid, perhaps woodward? I think the real stuff begins around 4pm and goes until 9 or 10 tonight.

man I'm looking at that storm in SW ok on GRanalyst, its impressive.

TORNADO WATCH FOR PORTIONS OF

PARTS OF WESTERN AND CENTRAL IOWA
PARTS OF NORTHWEST MISSOURI
PARTS OF SOUTHEAST NEBRASKA

EFFECTIVE THIS SUNDAY AFTERNOON AND EVENING FROM 1250 PM UNTIL
800 PM CDT.

TORNADOES...HAIL TO 3 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 80 STATUTE
MILES EAST AND WEST OF A LINE FROM 15 MILES WEST OF FALLS CITY
NEBRASKA TO 20 MILES NORTHEAST OF FORT DODGE IOWA. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU1).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND 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.

OTHER WATCH INFORMATION...CONTINUE...WW 189...WW 190...

DISCUSSION...WARM FRONT MOVING NWD THRU WRN IA/SERN NE AHEAD OF
SURFACE WV NEAR CNK. THIS PLACES WATCH AREA IN FAVORABLE
ENVIRONMENT FOR DEVELOPMENT OF TORNADIC SUPERCELLS AS SHEAR AND

AREAS AFFECTED...NW-WCNTRL TX AND EXTREME SWRN OK

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 261758Z - 261930Z

MID-LVL TROUGH AXIS CONTINUES TO ADVANCE EWD THROUGH ERN NM WITH
STRONGEST PVA LIKELY TO TRANSLATE INTO NWRN-WCNTRL TX THROUGH EARLY
THIS EVENING. BANDS OF ACCAS HAVE BEEN COMMONPLACE OVER W TX SINCE
EARLY MORNING WITH SFC BASED CBS DEVELOPING OVER THE ERN SIDES OF
THE GLASS MOUNTAINS IN PECOS COUNTY RECENTLY.

EXPECT THAT CLEAN INITIATION ALONG THE DRYLINE /NEARING THE CAPROCK
EARLY THIS AFTN/ WILL BE MUDDLED BY GRADUAL UPSCALE GROWTH/
DEEPENING OF THE ACCAS STREETS INTO TSTMS AS THE DEEP LAYERED UVV
APCHS. INITIAL STORMS WILL PRODUCE LARGE HAIL GIVEN STEEP LAPSE
RATES ATOP THE BOUNDARY LAYER. BUT...AS HEATING CONTINUES AND ACCAS
BOOTSTRAPS INTO THE MOIST BOUNDARY LAYER -AND- ADDITIONAL SFC-BASED
STORMS DVLP ALONG THE DRYLINE...ALL FACETS OF SVR WEATHER ARE LIKELY
AS STORMS EVOLVE INTO SUPERCELLS.

HIGHEST TORNADO POTENTIAL WILL EXIST ACROSS NWRN TX/ERN S PLNS WHERE
STRONGEST SELY LLVL FLOW WILL REMAIN THROUGH EVENING. FARTHER
S...THOUGH TORNADOES WILL BE A THREAT...THE LLVL FLOW/LARGE SCALE
SUPPORT WILL BE COMPARATIVELY WEAKER.

A TORNADO WATCH WILL BE REQUIRED FOR PARTS OF THE REGION LATER THIS
AFTN.

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

LARGE PART OF CENTRAL AND SOUTHWEST OKLAHOMA
PARTS OF NORTHWEST TEXAS

EFFECTIVE THIS SUNDAY AFTERNOON AND EVENING FROM 140 PM UNTIL
1000 PM CDT.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...

DESTRUCTIVE TORNADOES...LARGE HAIL TO 3 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 80 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 70 STATUTE

CHILDRESS TEXAS TO 25 MILES SOUTH SOUTHEAST OF CHANDLER OKLAHOMA.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU2).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND 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.

OTHER WATCH INFORMATION...CONTINUE...WW 189...WW 190...WW 191...

DISCUSSION...WITH STRONG SHEAR AND A VERY UNSTABLE ENVIRONMENT IN
PLACE...THUNDERSTORMS WILL RAPIDLY INTENSITY ALONG AND E OF DRY LINE
NWRN TX. SUPERCELLS WITH THE POTENTIAL FOR ISOLATED STRONG
TORNADOES ALONG WITH VERY LARGE HAIL WILL BECOME AN INCREASING
THREAT THROUGH THE AFTERNOON AS STORMS DEVELOP NEWD ACROSS THE WATCH
AREA.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 3 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 70 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO

The update is next. What do ya guys think ? Extend, remain or cancel the high risk ?

[CrazyC83]

It isn't verifying now, but I think they are committed to it so I don't see a lot of change.

0241 PM CDT SUN APR 26 2009

AREAS AFFECTED...WRN IA...ERN NEB AND ERN KS

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 261941Z - 262215Z

THIS DISCUSSION CONCERNS SVR TSTM WATCH 189 AND TORNADO WATCHES 190;
191.

19Z SFC ANALY SHOWS 2-3 MB PRESSURE FALLS CENTERED OVER ERN KS.
MESOLOW CONTINUES TO MIGRATE SLOWLY NEWD ALONG THE NEB-KS BORDER NW
OF KMHK. WRMFNT HAS DEVELOPED N OF I-80 WITH A BROAD WARM SECTOR
CHARACTERIZED BY CAPES RANGING FROM 1000 IN SRN IA TO 2000 J/KG IN
ERN KS. HBR PROFILER...RESIDING IN INFLOW REGION OF THE SFC
LOW...EXHIBITS OVER 225 M2/S2 OF 0-1KM SRH AND 50+ KTS OF BULK
SHEAR. WITH MINIMAL CINH NOTED ACROSS THE REGION...TSTMS WILL
CONTINUE TO DEVELOP AND SLOWLY TRANSLATE ENE ACROSS THE DISCUSSION
AREA THRU LATE AFTN.

CONVECTIVE MODE WILL CONTINUE TO BE MESSY WITH NUMEROUS STORMS BEING
GENERATED WITH VARIOUS COMPLEX MERGERS. OBVIOUSLY... MAGNITUDE OF
SHEAR AND INSTABILITY WILL REMAIN CONDUCIVE FOR HIGH PCPN SUPERCELLS
CAPABLE OF STRONG TORNADOES...LARGE HAIL AND DESTRUCTIVE WIND GUSTS.
THIS WILL ESPECIALLY BE TRUE ACROSS ERN KS SWD WHERE BEST
JUXTAPOSITION OF RICH MOISTURE INFLUX AND SHEAR WILL EXIST.
HOWEVER...FARTHER N...INSTABILITY GRADIENT WILL DEVELOP NWD WITH
TIME AND TORNADOES...DMGG WINDS AND HAIL RISKS WILL SPREAD ACROSS
CNTRL/NRN IA THROUGH EARLY EVENING.

FINALLY...THERE WILL BE A LARGE HAIL THREAT ACROSS ERN NEB AND NWRN
IA AS LEFT-SPLITS OF SUPERCELLS DEVIATE AND MOVE ATOP THE COLDER
BOUNDARY LAYER.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0259 PM CDT SUN APR 26 2009

VALID 262000Z - 271200Z

...THERE IS A HIGH RISK OF SVR TSTMS ACROSS PARTS OF WRN OK AND SRN
KS...

..THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF KS...OK
AND
TX...

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN AND
CNTRL PLAINS...UPPER MIDWEST AND LOWER OH VALLEY...

..CURRENT THINKING ACROSS THE MODERATE AND HIGH RISK AREAS

THE LARGE MCS FROM NW OK EXTENDING NNEWD ACROSS KS INTO NEB AND IA
IS ORGANIZING INTO A LINEAR MCS AND WILL CONTINUE TO HAVE A
WIDESPREAD SEVERE THREAT LATE THIS AFTERNOON INTO THE MID-EVENING.
RUC ANALYZED INSTABILITY AND VERTICAL SHEAR FIELDS APPEAR FAVORABLE
FOR AN EXTENSIVE SEVERE THREAT COVERAGE. LARGE HAIL AND WIND DAMAGE
SHOULD ACCOMPANY THE STRONGER CELLS IN THE SQUALL-LINE EWD ACROSS
THE REMAINDER OF KS INTO NW MO AND SRN IA. A FEW TORNADOES SHOULD
OCCUR WITH SUPERCELLS EMBEDDED IN THE LINE OR AHEAD OF THE LINE
THROUGH EARLY TO MID-EVENING.

FURTHER SOUTHWEST ACROSS THE HIGH RISK AREA...THE LATEST SHORT-TERM
THUNDERSTORM GUIDANCE SUGGESTS A SHORT LULL IN CONVECTIVE
DEVELOPMENT SHOULD OCCUR LATE THIS AFTERNOON AS THE SRN EDGE OF A
LARGE MCS EXITS TO THE NORTHEAST. THEN THE NEW RUC AND NAM FORECASTS
SUGGEST REPEAT INITIATION WILL OCCUR NORTH TO SOUTH ALONG MOST OF
THE DRYLINE IN THE 23Z TO 01Z TIMEFRAME. THE RUC ALSO SUGGESTS THE
STRONGER VERTICAL SHEAR PROFILES OF 50 TO 60 KT STILL LOCATED JUST
WEST OF THE HIGH RISK AREA WILL MOVE EWD INTO WRN OK BY EARLY
EVENING. THIS WILL STRENGTHEN VERTICAL SHEAR PROFILES WITH THE
LOW-LEVEL JET ALSO INCREASING ATTM HELPING STORMS THAT INITIATE TO
RAPIDLY OBTAIN SUPERCELL STRUCTURES CAPABLE OF PRODUCING LARGE HAIL
AND TORNADOES. THE THREAT FOR STRONG TORNADOES AND VERY LARGE HAIL
APPEARS TO BE THE GREATEST FROM AROUND WOODWARD OK SWD TO ABOUT
WICHITA FALLS TX WHERE AN AXIS OF LOW LCL HEIGHTS CURRENTLY EXISTS.
CONFIDENCE IS STILL HIGH THAT A CLUSTER OF TORNADIC SUPERCELLS
SHOULD ORGANIZE ALONG THIS CORRIDOR THIS EVENING.

..CHANGES TO THE OUTLOOK

NO AREAL CHANGES TO THE OUTLOOK FOR THE 20Z ISSUANCE.
