HIGH PRESSURE OFF THE SOUTHEAST COAST WILL CIRCULATE WARM AND MOIST AIR INTO THE AREA DURING THE PERIOD. AND CONVERGENCE INTO THE WEAK TROUGH SUPPORTS A CONTINUED THUNDERSTORM CHANCE. THE HIGH-RESOLUTION MODELS DISPLAY MAINLY SCATTERED COVERAGE. THE MODELS SHOW LINGERING MOISTURE ASSOCIATED WITH THE REMNANTS OF A COLD FRONT. LEANED TOWARD THE HIGHER GUIDANCE POPS BASED ON THE SURFACE FEATURE AND UPPER TROUGHING. THE GFS AND ECMWF DISPLAYED H5 RIDGING OVER THE FORECAST AREA THROUGH THE MEDIUM-RANGE PERIOD. THE GFS AND ECMWF MOS POPS WERE 10 TO 30 PERCENT DURING THE PERIOD WITH THE HIGH VALUES MAINLY EARLY WITH H5 RIDGING NOT QUITE AS STRONG.
