CHANCES OF RAIN WILL REMAIN HIGH AS LONG AS SURFACE BOUNDARY LINGERS
AROUND THE AREA. ALSO...THE SYSTEM COMING UP FROM THE SOUTH WILL
KEEP POPS UP. MUCH MOISTURE WILL BE IN PLACE TO PRODUCE HEAVY
RAIN...ESPECIALLY OVER NORTHWEST ARKANSAS TODAY AND NORTHERN
ARKANSAS TONIGHT. HEAVY RAINS WILL CONTINUE TO BE A POSSIBILITY FOR
THE LATTER HALF OF THE WEEKEND...AND IT WILL HAVE TO BE MONITORED
FOR POSSIBLE FLASH FLOOD WATCH. CLOUDS AND RAINS WILL MAKE TEMPS
DIFFICULT TO PEG. ANY BREAK IN THE CLOUDS WILL ALLOW TEMPS TO BOOM
AS WAS THE CASE YESTERDAY.
