AREAL COVERAGE HAS DECREASED AND WILL CONTINUE TO DO SO IN THE NEXT COUPLE OF HOURS. HOWEVER... LEFTOVER BOUNDARIES FROM THIS CONVECTION WILL AID IN NEW DEVELOPMENT DURING THE DAYLIGHT HOURS. IN ADDITION...A WEAK COLD FRONT IN EXTREME NORTHERN ARKANSAS WILL MOVE SLOWLY SOUTH DURING THE DAY...AIDING IN THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS. COLD FRONT NOT PACKING MUCH OF A PUNCH...AS THERE IS LACK OF MOISTURE...AND DRIER AIR IS STILL FAR BEHIND IN MISSOURI. THEREFORE...HIGH TEMPERATURES TODAY WILL STILL BE ON THE HOT SIDE. DUE TO THIS...ALONG WITH HIGH HUMIDITY VALUES...HAVE DECIDED TO REISSUE THE HEAT ADVISORY FOR THE CENTRAL AND SOUTH TODAY. LOCATION OF THE COLD FRONT AND ASSOCIATED CLOUD COVER/RAINFALL WILL BE A BIG PLAYER AS FAR AS TEMPERATURES...BUT CURRENT THINKING IS FRONT WILL NOT REACH CENTRAL ARKANSAS UNTIL MID AFTERNOON.

FRONT WILL BE SLOW TO MOVE OUT OF THE STATE...BUT PRECIPITATION WILL END OVERNIGHT. SLIGHTLY COOLER TEMPERATURES AND DRIER AIR WILL FOLLOW FOR TONIGHT THROUGH MONDAY.
