THAT WAA IN THE LLVLS W/A COLD CORE ALOFT WILL LEAD TO INSTABILITY. LAPSE RATES OF 6.5 TO 7.0 C/KM FROM 700-500MBS WILL ADD TO THE INSTABILITY. PLUS...TO ADD TO THIS IS THE CONVECTION OCCURRING OVER VT AND MOVING NE. ALL THIS COULD ALLOW FOR STRONGER WINDS ALOFT TO MIX DOWN LATER TONIGHT ACROSS THE WARNING AREA.
