   ...CNTRL/SCNTRL/SWRN OK INTO NCNTRL TX...
   DRYLINE SURGED NEWD INTO NCNTRL TX AND SWRN OK...BUT IS SHOWING
   SIGNS OF SLOWING DOWN AND MAY MOVE WWD AGAIN THIS EVENING.  TSTMS
   THAT INITIATED ALONG THE BOUNDARY ARE MOVING NEWD THROUGH SWRN/WRN
   OK ATTM...HEADING INTO CNTRL OK WHERE RECENT TSTMS HAVE STABILIZED
   THE BOUNDARY LAYER.  MESONET DATA SHOWS EVIDENCE OF SUB-SYNOPTIC
   LOW OVER SWRN OK AND LOW LEVEL WIND BACKED AND ACCELERATED OVER THE
   PAST COUPLE OF HOURS.  GREATER LOW LEVEL STORM RELATIVE HELICITY IN
   COMBINATION WITH WARMER BOUNDARY LAYER AIDED IN AN ENHANCED TORNADO
   THREAT ACROSS SWRN/SCNTRL OK AND NCNTRL TX...AND THIS SHOULD
   CONTINUE FOR A COUPLE MORE HOURS.
   
   OTHERWISE...LEFT SPLITS AND DEVELOPMENT OF OTHER TSTMS OCCURRING
   ACROSS CNTRL OK POSE A LARGE HAIL THREAT GIVEN STEEP MIDLEVEL LAPSE
   RATES.  THESE TSTMS...AND THE STORMS OVER NCNTRL TX...WILL MOVE
   NNEWD INTO SRN/CNTRL OK INTO ERN OK AND NERN TX DURING THE
   OVERNIGHT WITH A CONTINUED HAIL THREAT. 
   
   ...NRN OK NWD INTO THE CNTRL PLAINS...
   SLY LLJ IS EXPECTED TO BECOME FOCUSED FROM CNTRL/NRN OK INTO
   CNTRL/NRN KS OVERNIGHT.  AREA SOUNDINGS SAMPLED THE VERY STEEP
   MIDLEVEL LAPSE RATES AND THREAT OF HAIL WILL OCCUR MOST OF THE
   NIGHT.  DEEP LAYER SHEAR WILL BE RATHER LIGHT...SO MULTICELL STORMS
   WILL BE FAVORED.
   
   ...SRN FL...
   TRAILING LINE OF TSTMS CONTINUES TO MOVE ACROSS SRN FL ATTM. 
   EVENING ANALYSIS OF SURFACE/UPPER AIR DEPICTS DEEP LAYER WLY
   FLOW...AND THERE COULD BE A DAMAGING WIND GUST OR TWO AS THE STORMS
   APPROACH THE PBI-MIA REGIONS IN A COUPLE OF HOURS.  HAIL COULD ALSO
   OCCUR...AS MIDLEVEL LAPSE RATES REMAIN SOMEWHAT STEEP...ON THE
   ORDER OF 6.5 C/KM.  OTHERWISE...NLDN AND IR IMAGERY SUGGEST
   ELEVATED TSTMS DEVELOPING ACROSS THE ECNTRL GULF OF MX...AND THOSE
   MAY MOVE TOWARD PARTS OF SWRN FL LATER TONIGHT. THESE TSTMS SHOULD
   REMAIN SUB-SEVERE.
