   ...SYNOPSIS...
   
   LARGE SCALE UPPER RIDGE WILL BUILD EAST AND FLATTEN ACROSS THE SRN
   U.S. DURING THE DAY2 PERIOD AS GREAT BASIN UPPER TROUGH MOVES TOWARD
   THE CENTRAL ROCKIES.  AT THE SFC...ANY MEANINGFUL AREAS OF LOW LEVEL
   CONVERGENCE SHOULD EXIST ALONG FRONTAL ZONE STRETCHING FROM THE
   COASTAL CAROLINAS...SWWD ALONG THE CNTRL GULF COAST INTO THE COASTAL
   PLAINS OF TX.  AN ADDITIONAL FOCUS FOR POTENTIAL CONVECTIVE
   DEVELOPMENT WILL OCCUR LATE ACROSS THE CNTRL PLAINS AS LEE TROUGHING
   AND ENHANCED WARM ADVECTION AID POTENTIAL ELEVATED THUNDERSTORMS
   AFTER DARK.
   
   
   ...GREAT BASIN TO KS...
   
   SIGNIFICANT MID LEVEL COOLING ASSOCIATED WITH UPPER TROUGH WILL
   SPREAD ACROSS NV INTO WRN CO LATE IN THE PERIOD.  THIS FEATURE WILL
   UNDOUBTEDLY AID CONVECTIVE DEVELOPMENT...ESPECIALLY DURING THE
   AFTERNOON/EVENING HOURS AS LARGE SCALE FORCING SPREADS DOWNSTREAM. 
   VERY WARM 700MB TEMPERATURES...AOA 14C...WILL CAP RELATIVELY DRY
   BOUNDARY LAYER AIRMASS EAST OF THE ROCKIES ACROSS THE CNTRL PLAINS
   THROUGH EARLY EVENING. AFTER DARK...INCREASING LLJ AND WARM
   ADVECTION SHOULD RESULT IN ELEVATED THUNDERSTORM DEVELOPMENT ALONG
   THE KS/NE BORDER...ESPECIALLY AS COLD FRONT SHARPENS AND SURGES
   SOUTH INTO THIS REGION AFTER MIDNIGHT. MEAGER MOISTURE/INSTABILITY
   WILL LIMIT UPDRAFT STRENGTH/SEVERE PROBABILITIES ACROSS THIS REGION.
   
   
   ...GULF COAST/CAROLINA COAST...
   
   E-W ORIENTED FRONTAL ZONE WILL STALL ALONG THE GULF COAST REGION
   LATER IN THE DAY2 PERIOD AS SFC HIGH BUILDS EAST TOWARD THE MIDDLE
   ATLANTIC.  STRONG HEATING ALONG WRN/CNTRL PORTIONS OF THIS BOUNDARY
   WILL INCREASE INSTABILITY AND WEAKEN INHIBITION FOR POTENTIAL
   ISOLATED THUNDERSTORM DEVELOPMENT.  IT APPEARS CONVERGENCE WILL BE
   MINIMIZED WITH LITTLE LARGE SCALE SUPPORT BENEATH UPPER RIDGE...THUS
   LIMITING COVERAGE/INTENSITY FOR ANY STORMS THAT DEVELOP ACROSS THIS
   REGION.
