   ...SYNOPSIS...
   
   BROAD WARM ADVECTION REGIME WILL CONTINUE ACROSS THE LOWER MS VALLEY
   INTO THE GREAT LAKES/OH VALLEY REGION TODAY.  ANOTHER IN A SERIES OF
   UPPER SHORTWAVE TROUGHS WILL EJECT ENEWD ACROSS WY INTO THE UPPER
   GREAT LAKES REGION ENHANCING LARGE SCALE ASCENT ACROSS A REGION THAT
   WILL GRADUALLY MOISTEN/DESTABILIZE.  IT APPEARS STEEP MID LEVEL
   LAPSE RATES WILL ENHANCE ELEVATED INSTABILITY/CONVECTIVE THREAT
   ACROSS THE GREAT LAKES AHEAD OF SFC LOW.  DEEPER CONVECTION MAY
   PRODUCE ISOLATED LIGHTNING STRIKES.
   
   FARTHER SOUTH...WEAK LARGE SCALE HEIGHT FALLS WILL SPREAD SEWD ALONG
   FRONTAL ZONE THAT WILL STRETCH FROM SRN MO INTO OH BY THE END OF THE
   PERIOD.  MOIST SWLY TRAJECTORIES WILL PERSIST ACROSS THIS REGION
   WITH PERIODIC EPISODES OF LARGE SCALE ASCENT DUE MOSTLY TO WARM
   ADVECTION.  TIMING OF CONVECTIVE DEVELOPMENT WILL PROVE DIFFICULT
   AHEAD OF COLD FRONT AS ANY THUNDERSTORMS THAT DEVELOP WILL INITIATE
   WELL ABOVE THE BOUNDARY LAYER AND ONLY LOOSELY CORRELATED WITH
   FRONTAL ZONE.
   
   ...GREAT BASIN TO PACIFIC COAST...
   
   UPPER JET AXIS WILL SAG SEWD ACROSS THE GREAT BASIN WITH VERY COLD
   THERMODYNAMIC PROFILES EXPECTED ON CYCLONIC SIDE OF STRONGER FLOW. 
   STEEP LAPSE RATES WILL PROVE FAVORABLE FOR POCKETS OF LOCALLY
   ENHANCED INSTABILITY...HOWEVER PROFILES ARE QUITE COLD AND THE
   PROBABILITY OF LIGHTNING MAY BE REDUCED ACROSS AN OTHERWISE
   FAVORABLE ZONE FOR THUNDERSTORMS.  GREATEST CONCENTRATION OF DEEP
   CONVECTION CAPABLE OF PRODUCING LIGHTNING MAY OCCUR ACROSS ERN UT
   AND WRN CO...ALONG WITH COASTAL PORTIONS OF THE PACIFIC WHERE MARINE
   LAYER WILL PROVIDE HIGHER MOISTURE CONTENT WITHIN THE CLOUD LAYER.
