Surprise??

MESOSCALE DISCUSSION 0521

NWS STORM PREDICTION CENTER NORMAN OK

0942 AM CDT SAT APR 14 2012

AREAS AFFECTED...TX/OK PANHANDLES...WRN OK...SWRN KS

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

VALID 141442Z - 141615Z

CONVECTIVE INITIATION MAY BE UNDERWAY ACROSS PARTS OF THE SRN/CNTRL

HIGH PLAINS. TRENDS WILL BE MONITORED DURING THE NEXT FEW

HOURS...AND A TORNADO WATCH WILL LIKELY BE ISSUED FOR THE TX/OK

PANHANDLES...WRN OK...AND SWRN KS IF THE THREAT FOR DEEPENING

CONVECTION ACTUALLY MATERIALIZES.

RECENT VISIBLE SATELLITE LOOP INDICATES A ZONE OF TOWERING CUMULUS

EVOLVING FROM FAR SWRN KS SSWWD INTO THE CNTRL TX PANHANDLE. THIS

ZONE ALIGNS WITH A RIBBON OF INFERRED ASCENT PER RECENT WATER VAPOR

IMAGERY. THE 12Z AMARILLO RAOB MODIFIED FOR CURRENT SFC OBS

INDICATES THAT INHIBITION FOR A SURFACE-BASED PARCEL HAS ALMOST

COMPLETELY ERODED OVER THE TX/OK PANHANDLES...PARTICULARLY IN

POCKETS OF INSOLATION. FARTHER NORTH INTO SWRN KS -- I.E. NORTH OF

THE TRACK OF ASCENT ATTENDANT TO A PRIOR SUBTLE IMPULSE -- THE CAP

IS MUCH MORE STOUT PER DODGE CITY 12Z RAOB. REGARDLESS...CONTINUED

SFC HEATING WILL LIKELY RESULT IN STRONG DESTABILIZATION AND

DECREASING INHIBITION THROUGH THE LATE MORNING INTO THE EARLY

AFTERNOON EAST OF A SHARPENING DRYLINE/FRONT...AND CONVECTIVE

INITIATION MAY BE IMMINENT. ALSO OF NOTE...DETERMINISTIC MODEL QPF

FIELDS HAVE STRUGGLED GREATLY WITH REGARDS TO REPRESENTING THE

CURRENT SCENARIO...AND LIKELY ARE NOT RESOLVING SUBTLE FORCING FOR

ASCENT THAT WILL PLAY A KEY ROLE IN SUPPORTING THE INITIATION.

STRONG LOW-LEVEL SHEAR YIELDING EFFECTIVE SRH IN EXCESS OF 300

M2/S2...MAINTAINED BY BACKED SFC WINDS...WILL SUPPORT A THREAT FOR

TORNADOES...WHILE VERY LARGE HAIL AND DMGG WINDS ARE ALSO EXPECTED

WITH SUPERCELL STRUCTURES.

Would this lower the threat for this evening?

think this early activity will lessen the chance of the stronger stuff this evening?

If it goes linear and merges into an MCS then yes, if not it could make this day very bad for some areas of KS, we had a day 3 or 4 years ago along I-70 in KS where initiation occurred late AM and we had tornadoes going up for about 7 or 8 straight hours.
