   ATLANTIC EARLY SATURDAY. LOW LEVEL FLOW WILL VEER AHEAD OF THIS
   ACTIVITY...LIMITING CONVERGENCE AS SHORTWAVE TROUGH LIFTS NEWD INTO
   THE OH VALLEY AND NERN STATES. LOW 60S DEWPOINTS HAVE ADVECTED NEWD
   INTO THE CAROLINAS AND SRN VA. HOWEVER...AS LOW LEVEL FLOW VEERS
   THROUGH EARLY SATURDAY...FURTHER ADVECTION OF MOISTURE WILL BE
   LIMITED. THIS IN CONJUNCTION WITH WEAK LAPSE RATES AND PRESENCE OF
   MID LEVEL INVERSION SUGGEST INSTABILITY WILL REMAIN MARGINAL E OF
   THE LINE. CONVECTION WILL BE EMBEDDED WITHIN STRONG UNIDIRECTIONAL
   FLOW REGIME WITH 55-60 KT JUST OFF THE SURFACE. ACTIVITY IS EXPECTED
   TO WEAKEN AS IT CROSSES THE MOUNTAINS AND ENCOUNTERS DOWNSLOPE
   REGIME AND MARGINAL THERMODYNAMIC PROFILES..BUT MAY INCREASE AGAIN
   AS IT APPROACHES ERN NC INTO ERN VA WHERE POTENTIAL FOR AN ISOLATED
   DAMAGING WIND GUST OR TWO MAY EXIST. GIVEN LIMITED POTENTIAL FOR
   DESTABILIZATION...ONLY LOW PROBABILITIES ARE WARRANTED.
   
   ...UPPER MS VALLEY THROUGH GREAT LAKES....
   
   STRONG IMPULSE NOW DROPPING INTO THE NWRN U.S. WILL CONTINUE EWD
   INTO THE GREAT LAKES REGION THIS EVENING. LOW LEVEL FLOW WILL BACK
   AND STRENGTHEN IN EXIT REGION OF ASSOCIATED JET...RESULTING IN
   STRONG WARM ADVECTION. STEEP LAPSE RATES ACCOMPANYING COLD AIR ALOFT
   WILL ALSO SPREAD OVER THIS AREA AND IN CONJUNCTION WITH LOW LEVEL
   WARM ADVECTION WILL CONTRIBUTE TO DESTABILIZATION. ISOLATED
   LIGHTNING STRIKES MAY ACCOMPANY THE CONVECTION DEVELOPING IN THE
   WARM ADVECTION REGIME...BUT INSTABILITY WILL REMAIN LIMITED DUE TO
   MEAGER MOISTURE.
