Area forecast discussion, Jun 24, 4:00 PM CDT, 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 400 PM CDT MON JUN 24 2002 UPPER LOW REMAINS IN SOUTHERN LOUISIANA. SHOWERS AND THUNDERSTORMS HAVE BECOME MORE NUMEROUS ACROSS THE AREA TODAY COMPARED TO YESTERDAY WITH THE MOST COVERAGE IN THE SOUTH AND WEST. OVERALL COVERAGE ABOUT 20 PERCENT...SO POPS A LITTLE OVERFORECAST FOR TODAY. TROF STILL PROGGED TO DRIFT NORTHWEST AND WEAKEN AS HEIGHTS SLOWLY RISE. IT IS FORECAST TO MOVE TO A POSITION TO PUT ALL OF ARKANSAS ON THE FAVORED EAST SIDE FOR COVERAGE OF SHOWERS AND THUNDERSTORMS. LOOKS LIKE THE BEST CHANCE OF RAIN WILL BE THE NEXT TWO AFTERNOONS. THERE WILL BE ENOUGH MOISTURE AND INSTABILITY FOR SOME CHANCE OF RAIN ALL THE TIME THE NEXT FEW DAYS...SO WILL CARRY POPS BOTH DAY AND NIGHT. WITH THE UPPER LOW THE STRONGEST THE NEXT TWO DAYS...WILL GO WITH 30 PERCENT POPS DURING THE NIGHT IN CENTRAL AND SOUTHERN SECTIONS WITH 50 PERCENT POPS FOR THE NEXT TWO AFTERNOONS. POPS WILL GRADUALLY LOWER AFTER THAT AS THE UPPER LOW WEAKENS...BUT WILL CONTINUE WITH 30 PERCENT POPS DURING THE AFTERNOON AND 20 PERCENT THE REST OF THE DAY. MODELS SHOW A FRONT MOVING INTO NORTHERN ARKANSAS LATER IN THE WEEK BUT IT LIKELY WILL BE LITTLE MORE THAN A BOUNDARY TO FOCUS CONVECTION AND ITS LOCATION WILL BE DOMINATED BY MESOSCALE FEATURES. BY THE FIRST OF NEXT WEEK...UPPER RIDGING BEGINS TO DEVELOP AND A RETURN TO MORE TYPICAL SUMMER CONDITIONS SHOULD OCCUR WITH MAXES RISING INTO THE LOWER 90S AND A 20 PERCENT CHANCE OF AFTERNOON THUNDERSTORMS. TEMPS IN THE SHORT TERM WILL GENERALLY BE MINS IN THE MID AND UPPER 60S IN THE NORTH WITH NEAR OR A LITTLE ABOVE 70 ELSEWHERE AND MAXES MID 80S IN THE NORTH AND MID TO UPPER 80S ELSEWHERE. .LZK...NONE
