   ...SYNOPSIS...
   SEVERE THUNDERSTORM POTENTIAL WILL BE INHIBITED TUESDAY AS STABILITY
   INCREASES WITHIN CONTINENTAL AIR MASS SETTLING SWD ALONG BACK SIDE
   OF ERN U.S. LONG WAVE TROUGH.  THE EXCEPTION WILL BE ACROSS FL WHERE
   A DEEPLY MOIST AIR MASS IS EXPECTED TO REMAIN ALONG AND JUST BEHIND
   QUASISTATIONARY FRONT ACROSS THE CENTRAL PENINSULA.  HOWEVER ...VERY
   LIMITED LAPSE RATES WILL ONLY SUPPORT MARGINAL INSTABILITY WHILE
   DEEP LAYER SHEAR REMAINS WEAK. ELSEWHERE...LOW TOPPED CONVECTION IS
   EXPECTED OVER PORTIONS OF THE GREAT LAKES WHERE H7 TEMPERATURES OF
   -12C TO -16C SETTLE OVER WARM LAKE SURFACE TEMPERATURES.  BEST
   POTENTIAL FOR A FEW THUNDERSTORMS IS EXPECTED OVER THE ERN LAKES
   WHERE LAKE SURFACES SHOULD BE A BIT WARMER.  ELEVATED THUNDERSTORMS
   ARE ALSO ANTICIPATED EARLY IN THE PERIOD OVER PORTIONS OF OK AND THE
   TX PANHANDLE WHERE STEEP LAPSE RATES ARE EXPECTED TO SUPPORT WEAK
   INSTABILITY ALONG NOSE OF SSWLY LLJ.
