   ...SYNOPSIS...
   COLD LOW SURFACE AND ALOFT REMAINS JUST OFF NRN CA COAST WITH SLOW
   FILLING THRU THE PERIOD. DOWNSTREAM...LOW AMPLITUDE RIDGE LOCATED 
   HIGH PLAINS WITH CONFLUENT WLY FLOW ACROSS GREAT LAKES.  WEAK
   S/WV/MID LEVEL LOW CENTRAL TX WILL CONTINUE EWD. 
   
   SFC LOW N OF GREAT LAKES WITH COLD FRONT TRAILING SWWD INTO NRN IL
   TO ERN KS AND WRN OK. CONVECTIVE MCS NRN MO CONTINUES TO MOVE EWD
   ACROSS MID MS VALLEY RESULTING IN COLD POOL PRODUCING AN OUTFLOW 
   BOUNDARY EXTENDING WWD ACROSS LOWER MO VALLEY THIS AFTERNOON. S OF
   FRONT/BOUNDARY SLY LOW LEVEL FLOW CONTINUES TO GRADUALLY INCREASE
   GULF MOISTURE NWD WITH STEEP MID LEVEL LAPSE RATES SPREADING EWD
   ACROSS PLAINS.  
   
   ...CENTRAL PLAINS LOWER MO VALLEY...
   MCS CONTINUES EWD ACROSS MID MS VALLEY IN ONLY MARGINALLY FAVORABLE
   SHEAR AND INSTABILITY ENVIRONMENT.  OUTFLOW BOUNDARY WILL EXTEND
   WWD ACROSS MO INTERSECTING FRONTAL ZONE SERN KS. WITH THE STEEP MID
   LEVEL LAPSE RATES ACROSS THIS AREA OF 8-9C/KM AND STRONG HEATING IN
   WARM SECTOR...AIRMASS WILL BECOME MODERATELY UNSTABLE BY MID
   AFTERNOON WITH MLCAPES TO 2000 J/KG.  AS CAP WEAKENS STRONG/SEVERE
   THUNDERSTORMS WILL REDEVELOP VICINITY BOUNDARIES.  WITH SFC-6KM
   SHEAR GENERALLY LESS THAN 30KT...MULTICELLS WILL BE STORM MODE
   WITH PRIMARY THREAT LARGE HAIL AND ISOLATED WIND DAMAGE.
   
   ...CENTRAL HIGH PLAINS...
   UPSLOPE DEVELOPS FRONT RANGE DURING AFTERNOON WITH SUFFICIENT
   MOISTURE COUPLED WITH STEEP LAPSE RATES FOR DEVELOPMENT OF
   MARGINALLY UNSTABLE AIRMASS  WITH MLCAPES TO 1000 J/KG.  GIVEN
   VEERING SHEAR PROFILES STORMS THAT DEVELOP MID/LATE AFTERNOON WILL
   BECOME POTENTIALLY SEVERE WITH LARGE HAIL DOMINANT THREAT.  A FEW
   SUPERCELLS POSSIBLE GIVEN THE VEERING PROFILES ENHANCING HAIL
   THREAT ALONG WITH ISOLATED TORNADOES.
   
   STORMS SHOULD DEVELOP EWD ACROSS CENTRAL PLAINS TO N OF FRONTAL
   ZONE IN AREA OF FAVORABLE WARM ADVECTION AS NOCTURNAL LOW LEVEL JET
   DEVELOPS.  CONTINUED THREAT OF LARGE HAIL WITH POSSIBLE MCS
   DEVELOPMENT VICINITY NE/KS BORDER OVERNIGHT. AGAIN LACK OF STRONG
   DEEP LAYER SHEAR WILL LIMIT  DAMAGING WIND CONCERN.
   
   ...SRN HIGH PLAINS...
   GULF MOISTURE CONTINUES TO WORK NWWD INTO SWRN TX. WITH DEWPOINTS
   TO AROUND 60F AS FAR W AS PECOS RIVER VALLEY.  COUPLED WITH STRONG
   HEATING...MODERATE INSTABILITY WILL DEVELOP BY MID AFTERNOON WITH
   MLCAPES TO 2000 J/KG. AGAIN SHEAR RATHER WEAK THIS AREA..BUT WITH
   DIFLUENT UPPER FLOW AND STEEP MID LEVEL LAPSE RATES A FEW SEVERE
   THUNDERSTORMS ARE LIKELY.  VEERING WIND PROFILES IN LOW LEVEL
   SUGGESTS ISOLATED SUPERCELLS POSSIBLY ENHANCING  LARGE
   HAIL THREAT.
   
   ...CA CENTRAL VALLEY...
   WITH SFC/UPPER COLD LOW REMAINING JUST OFFSHORE NRN CA...FAVORABLE
   VEERNG SHEAR PROFILES WILL  BE IN PLACE SACRAMENTO VALLEY  THIS
   AFTERNOON FOR POSSIBLE LOW TOPPED ROTATING STORMS.  STEEP LAPSE
   RATES AROUND 7-8C/KM WILL COMPENSATE FOR EXPECTED MARGINAL CAPES
   LESS THAN 500 J/KG FOR SUPPORT OF THUNDERSTORMS.  GIVEN THE COLD
   AIRMASS...PRIMARY THREAT WILL BE MARGINALLY SEVERE HAIL...WITH
   POSSIBLY A BRIEF TORNADO ASSOCIATED WITH ANY ROTATING STORMS.
   
   ...NRN INTERMOUNTAIN REGION...
   NEAR ADIABATIC LAPSE RATES OF 9C/KM AND VORT LOBE ROTATING NEWD
   ACROSS NRN INTERMOUNTAIN REGION...WILL BE SUFFICIENT FOR
   THUNDERSTORM DEVELOPMENT THIS AFTERNOON  NRN NV INTO SWRN ID.  COLD
   AIR ALOFT WOULD SUPPORT HAIL IN THE STRONGER STORMS ALONG WITH
   BRIEF GUSTY DOWNBURST WINDS GIVEN THE STEEP LAPSE RATES.
   
   ...SRN FL...
   SHEAR HAS WEAKENED WITH SOME DRYING SINCE YESTERDAY ACROSS S FL.
   HOWEVER WITH MODERATE INSTABILITY OF 2000 J/KG MUCAPES DURING
   AFTERNOON AND RELATIVELY COOL MID LEVEL TEMPERATURES...ISOLATED
   STRONG/SEVERE STORMS POSSIBLE WITH HAIL AGAIN PRIMARY THREAT.
