   NWS STORM PREDICTION CENTER NORMAN OK
   0352 PM CDT FRI MAR 29 2013
   
   AREAS AFFECTED...PORTIONS OF WRN/CNTRL NEB
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 292052Z - 292215Z
   
   PROBABILITY OF WATCH ISSUANCE...5 PERCENT
   
   SUMMARY...TSTM COVERAGE IS EXPECTED TO INCREASE OVER THE NEXT COUPLE
   HRS ACROSS CNTRL NEB...WITH THE PRIMARY THREATS BEING ISOLATED
   STRONG WIND GUSTS AND MARGINALLY SVR HAIL. A WW IS NOT ANTICIPATED.
   
   DISCUSSION...WATER VAPOR LOOP SHOWS A WEAK IMPULSE TRAVERSING EWD
   OUT OF WY INTO THE NEB PANHANDLE...WITH AN ASSOCIATED AREA OF
   FORCING FOR ASCENT CONTRIBUTING TO INCREASING CU COVERAGE ACROSS
   SERN WY AND THE SRN NEB PANHANDLE. MEANWHILE...A SFC TROUGH/DRYLINE
   WAS ANALYZED FROM NEAR 50 E CDR SWD TO 40 W IML...WITH UPPER 30S TO
   LOWER 40S F DEWPOINTS SLOWLY ADVECTING NWD INTO CNTRL NEB. DESPITE
   MEAGER BOUNDARY LAYER MOISTURE...AMPLE HEATING E OF THE SFC TROUGH
   BENEATH STEEP MIDLEVEL LAPSE RATES HAVE YIELDED ESTIMATED MLCAPE
   VALUES AROUND 500 J/KG. 
   
   LATEST VISIBLE SATELLITE IMAGERY SHOWS A CLUSTER OF TOWERING CU
   GROWING INCREASINGLY ROBUST OVER THE PAST HALF HR OVER THE FAR ERN
   NEB PANHANDLE...WHERE LOW-LEVEL CONVERGENCE IS LIKELY MAXIMIZED
   ALONG THE SFC TROUGH. MODEST VEERING OF WINDS WITH HEIGHT COMBINED
   WITH 30 KTS OF MIDLEVEL FLOW /PER LNX VWP DATA/ WILL BE SUPPORTIVE
   FOR MARGINALLY ORGANIZED STRUCTURES WITH THE STRONGEST STORMS.
   HOWEVER...THE OVERALL THREAT IS EXPECTED TO BE LIMITED BY WEAK
   BUOYANCY...PRECLUDING ISSUANCE OF A WW ATTM.
