AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 342 PM EDT TUE AUG 23 2005 .SHORT TERM /TONIGHT THROUGH FRIDAY/...CONVECTION HAS BEEN SLOW TO GET GOING ACROSS THE AREA TODAY. DEEP WLY FLOW HAS KEPT THE SEABREEZE CLOSE TO THE COAST AND DECENT AMOUNT OF CIRRUS HAS NOT ALLOWED MOST AREAS TO REACH CONVECTIVE TEMP. A WEAK VORT INITIALIZED BY THE GFS OVER SRN GA WILL MOVE UP THE COAST TONIGHT. ALTHOUGH A DISCRETE MCS COULD FORM...WILL FAVOR MORE SCATTERED CONVECTION OVERNIGHT WITH APPROXIMATELY 50 POPS. REMNANT OUTFLOWS AND A VERY MOIST ATMOSPHERE SHOULD ALLOW ACTIVITY TO IGNITE MOST OF THE NIGHT. ON WEDNESDAY...THE WEAK FRONTAL BOUNDARY DRAPED ACROSS THE CAROLINAS AND NRN GEORGIA WILL SINK FARTHER SOUTH AND SHOULD ENHANCE CONVECTION A BIT.
