OF THE ACTUAL FRONT.  SIGNIFICANT DEWPOINT PACKING SEEN IN THE MSAS
DATA ACROSS THIS AREA.  AS TSRA DEVELOP AND MOVE E..BOUNDARIES ARE
LIKELY TO SHIFT SWRD AND THIS COULD INITIATE SHRA/TSRA LATE
TONIGHT.  MAIN THREAT OF PCPN SHD COME ON FRI (ALTHOUGH SLIM ATTM).
SHD CONT TO SEE A DECREASE ON THE LOW LVL MOISTURE WHILE MID AND
