   ...SYNOPSIS...
   MID-LEVEL LOW CURRENTLY OVER ERN NV/WRN UT IS FORECAST TO OPEN AND
   PROGRESS EWD IN RESPONSE TO SEASONABLY STRONG MID AND UPPER-LEVEL
   JETS EJECTING FROM THE TROUGH BASE INTO THE NRN/CNTRL PLAINS. AT
   THE SURFACE...QUASI-STATIONARY FRONTAL BOUNDARY EXTENDS FROM CNTRL
   MN THROUGH SERN SD SWWD TO A BROAD AREA OF LOW PRESSURE OVER ERN
   CO. THIS FRONTAL SYSTEM WILL BEGIN TO PROGRESS EWD AS A COLD FRONT
   LATER IN THE PERIOD IN RESPONSE TO APPROACHING UPSTREAM TROUGH.
   
   ...SIGNIFICANT SEVERE WEATHER EPISODE POSSIBLE THIS AFTERNOON AND
   TONIGHT FROM THE CNTRL PLAINS INTO THE UPPER MS VALLEY/GREAT
   LAKES...
   
   ...SD/NEB EWD INTO THE UPPER MS VALLEY/WRN GREAT LAKES...  
   RICH...BOUNDARY-LAYER AIR MASS EXISTS THIS MORNING ACROSS KS/SRN
   NEB INTO SRN IA...ALONG AND TO THE S OF OUTFLOW BOUNDARY THAT
   STRETCHES FROM SWRN NEB NEWD INTO E-CNTRL NEB AND CNTRL IA.
   INCREASING LOW-LEVEL SLY/SELY WINDS SHOULD ADVECT THIS MOISTURE NWD
   TO VICINITY OF PRIMARY SYNOPTIC FRONT LATER TODAY. THIS INCREASE IN
   BOUNDARY-LAYER MOISTURE IN CONJUNCTION WITH DIURNAL HEATING AND
   STEEP MID-LEVEL LAPSE RATES WILL CONTRIBUTE TO CONSIDERABLE AIR
   MASS DESTABILIZATION WITH MLCAPES INCREASING TO 3500-4500 J/KG IN
   SOME AREAS.
   
   SUSTAINED LOW-LEVEL WAA/CONVERGENCE INVOF SYNOPTIC FRONT AND
   AFOREMENTIONED OUTFLOW BOUNDARY SHOULD CONTRIBUTE TO RAPID TSTM
   DEVELOPMENT THIS AFTERNOON/EVENING ACROSS THE MODERATE RISK AREA
   FROM WRN/CNTRL NEB INTO SERN SD/SWRN MN/NWRN IA. FORCING FOR ASCENT
   AHEAD OF VORTICITY CENTER LIFTING NEWD ACROSS CNTRL KS MAY HELP
   INITIATE ADDITIONAL STORMS ALONG THE OUTFLOW BOUNDARY FROM ERN NEB
   INTO IA.
   
   INITIALLY...SUPERCELLS WITH VERY LARGE HAIL AND DAMAGING WINDS WILL
   BE LIKELY GIVEN 45-55KTS OF 0-6KM SHEAR AND THE STRONG INSTABILITY.
   THE GREATEST TORNADO THREAT APPEARS TO BE LATE THIS AFTERNOON INTO
   EARLY EVENING FROM CNTRL NEB NEWD INTO NERN NEB/FAR SERN SD. HERE
   BACKED LOW-LEVEL SURFACE WINDS INVOF QUASI-STATIONARY FRONT AND/OR
   RETREATING OUTFLOW BOUNDARY AND BACKING/STRENGTHENING LLJ WILL BE
   COINCIDENT WITH RELATIVELY MOIST AND BUOYANT BOUNDARY-LAYER
   CONDITIONS.
   
   SUPERCELLS/SUPERCELL CLUSTERS WILL LIKELY MERGE INTO ONE OR MORE
   SEVERE MCS/S THIS EVENING WITH THE POTENTIAL FOR DAMAGING WINDS
   EXISTING ALONG THE SYSTEM TRACK/S INTO THE WRN GREAT LAKES.
   
   ...KS AND THE SRN HIGH PLAINS...
   12Z DDC/AMA/MAF SOUNDINGS INDICATE STEEP MID-LEVEL LAPSE RATES
   PRESENT THIS MORNING ACROSS THE CNTRL/SRN HIGH PLAINS. THESE LAPSE
   RATES...STRONG INSOLATION AND MOIST AIR MASS IN PLACE WILL
   CONTRIBUTE TO AFTERNOON MLCAPES OF 2000-3500 J/KG E OF DRYLINE. IN
   ADDITION...12Z ABQ/DNR SOUNDINGS INDICATED RELATIVELY STRONG MID-
   LEVEL WINDS /50KTS AT 500MB/ WHICH SHOULD OVERSPREAD THE WARM
   SECTOR LATER TODAY. DEEP MIXING INVOF DRYLINE SHOULD BE SUFFICIENT
   TO INITIATE ISOLATED STORMS THIS AFTERNOON/EVENING. DEEP-LAYER
   SHEAR SHOULD BE SUFFICIENT FOR ORGANIZED TSTMS...INCLUDING
   SUPERCELLS GIVEN THE PRESENCE OF THE STRONGER UPSTREAM MID-LEVEL
   WINDS. LARGE HAIL APPEARS TO BE THE PRIMARY SEVERE WEATHER THREAT. 
    
   ...INTERIOR NEW ENGLAND...
   SURFACE DEWPOINTS IN THE 60S AND DAYTIME HEATING WILL CONTRIBUTE TO
   AFTERNOON MLCAPES OF 1000-1500 J/KG FROM WRN ME SWD THROUGH NH INTO
   CNTRL MA/CT. WEAK CONVERGENCE INVOF N-S BOUNDARY MAY BE SUFFICIENT
   TO INITIATE A FEW TSTMS LATER TODAY. PRESENCE OF MODEST NLY MID-
   LEVEL WINDS /30-35KTS AT 500MB/ SUGGESTS THE POTENTIAL FOR SOME
   TSTM ORGANIZATION WITH ISOLATED STRONG WIND GUSTS/HAIL WITH THE
   MOST INTENSE STORMS.
