Severe weather outbreak? March 23-24 - Plains/Midwest

[KWT]

Yep always the way, seems like something has finally happened that has required a torndo warning to come out.

Looking at the radar already seems like things are becoming more linear in nature though there are still a few cells ahead of the main line.

[Ed Mahmoud]

There were seven chasers just from TVN on that cell with a hook. I guess they told the NWS that nothing is happening so they issue no warning.

That could explain it. But I thought the wonder of the WSR-88D was a cell could be warned before the funnel became visible?

VALID 232208Z - 232345Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 54 CONTINUES.

CONTINUE WW E OF DRYLINE DELINEATED BELOW UNTIL REPLACED OR DRYLINE
PASSES. ADDITIONAL WW ISSUANCE(S) LIKELY WILL BE NECESSARY FOR
AREAS S AND E OF WW 54...FROM CENTRAL OK NEWD TO VICINITY KS/MO
BORDER. THIS IS BASED ON PRESENCE OF DISCRETE SUPERCELLS AND
DEVELOPING TSTMS/FUTURE SUPERCELLS OVER NERN AND EXTREME S-CENTRAL
KS...MOVING INTO NARROW ZONE OF FAVORABLE ENVIRONMENT...THAT SHOULD
MOVE NEWD 35-45 KT OUT OF WW WITHIN NEXT 1-2 HOURS.

SFC ANALYSIS SHOWS PROGRESSIVE DRYLINE FROM WASHINGTON COUNTY KS
SWWD ACROSS RENO COUNTY KS TO NEAR LTS. THIS DRYLINE SHOULD
CONTINUE EWD...FASTER OVER KS THAN OK...FORMING WRN BOUND TO
SIGNIFICANT CONVECTIVE POTENTIAL. VIS IMAGERY INDICATES NARROW
CORRIDOR OF CLEARING W OF STRATUS/STRATOCU PLUME THAT EXTENDS FROM
NW TX NNEWD ACROSS EXTREME ERN KS AND WRN MO. THIS CORRIDOR SHOULD
SHIFT NEWD ACROSS KS/MO BORDER BEFORE SUNSET...ALLOWING DIABATIC
HEATING TO DESTABILIZE BOUNDARY LAYER AND WEAKEN MLCINH SUFFICIENTLY
TO SUPPORT CONVECTION MOVING RAPIDLY NEWD FROM CENTRAL PORTIONS
KS/OK. ACTIVITY ALSO MAY BACKBUILD SLIGHTLY S OF I-40 IN CENTRAL
OK...ALTHOUGH WITH CENTRAL PLAINS UPPER LOW LIFTING NEWD...SRN
FRINGE OF HEIGHT FALLS ALOFT...AND FAVORABLE DEEP-LAYER ASCENT AND
LAPSE RATES -- SHOULD NOT GET FARTHER S THAN AT PRESENT. KINEMATIC
GEOMETRY AROUND CENTRAL PLAINS LOW WILL CONTINUE TO ALIGN DEEP-LAYER
SHEAR VECTORS WITH SUFFICIENTLY NORMAL COMPONENT TO BOUNDARY FOR
SOME DISCRETE STORMS FOR A FEW MORE HOURS BEFORE FLOW BACKS IN
ADVANCE OF SWRN CONUS SHORTWAVE TROUGH. THIS ENVIRONMENT...COMBINED
WITH FAVORABLE LOW LEVEL SHEAR -- E.G. 0-1 KM SRH 300-500 J/KG --
WILL SUPPORT MIX OF QUASI-LINEAR AND DISCRETE SUPERCELL MODES...THE
LATTER SUPPORTING SIGNIFICANT/DAMAGING HAIL. TORNADO POTENTIAL IS
INCREASING FOR DISCRETE STORMS MOVING INTO AREAS OF MORE BACKED FLOW
AND HIGHER BOUNDARY LAYER RH NEAR MO VALLEY...SWD OVER SERN KS/NERN
OK...BEFORE MLCINH BECOMES TOO STG TO SUSTAIN SFC-BASED INFLOW.

520 PM CDT MON MAR 23 2009

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

CENTRAL AND SOUTHWEST OKLAHOMA
WESTERN NORTH TEXAS

EFFECTIVE THIS MONDAY AFTERNOON FROM 520 PM UNTIL MIDNIGHT CDT.

TORNADOES...HAIL TO 1.5 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 60 STATUTE
MILES EAST AND WEST OF A LINE FROM 25 MILES NORTHEAST OF PONCA
CITY OKLAHOMA TO 30 MILES SOUTH SOUTHWEST OF FORT SILL OKLAHOMA.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU6).

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 54...WW 55...

DISCUSSION...TCU/CBS ARE DEVELOPING SOUTHWESTWARD ALONG DRYLINE FROM
THE KS/OK BORDER TO JUST EAST OF CDS. CONVECTION IS EXPECTED TO
CONTINUE TO INCREASE IN INTENSITY AND COVERAGE THROUGH THE EVENING
WITH A FEW SUPERCELLS POSSIBLE. DAMAGING WINDS AND HAIL ARE THE
MAIN THREATS...BUT STRENGTH OF LOW LEVEL VERTICAL SHEAR ALSO WILL
SUPPORT A RISK OF TORNADOES.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 1.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
450. MEAN STORM MOTION VECTOR 24040.
