THE THUNDERSTORMS MAY PRODUCE GUSTY WINDS AND SOME HAIL...WIDESPREAD
SEVERE WEATHER IS NOT ANTICIPATED.

THE FRONT WILL SLOW TO A CRAWL TONIGHT AS IT BECOMES PARALLEL TO THE

SHOWERS AND THUNDERSTORMS...WITH LOCALLY HEAVY RAIN POSSIBLE OVER
THE NORTH...WILL BE ONGOING FRIDAY MORNING. THE FRONT WILL BE
LOCATED ROUGHLY FROM FORT SMITH TO MEMPHIS WHEN IT WILL BEGIN TO
STALL WITH A CONTINUING CHANCE OF PRECIPITATION. ONCE AGAIN THE BEST
CHANCES WILL BE OVER THE NORTH.

RAIN CHANCES WILL CONTINUE FRIDAY NIGHT INTO SATURDAY...BEFORE THE
FRONT BEGINS TO DISSIPATE. RAIN CHANCES WILL DECREASE DURING THE
EVENING HOURS SATURDAY...BUT WITH PLENTY OF MOISTURE LEFT ACROSS THE
STATE...AFTERNOON SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE SUNDAY
AFTERNOON.

HIGH PRESSURE WILL BUILD INTO THE STATE IN THE WAKE OF THE FRONT AND
REMAIN THROUGH THE REMAINDER OF THE PERIOD. ONLY A SLIGHT CHANCE
OF AFTERNOON SHOWERS AND THUNDERSTORMS DEVELOPING IN THE HEAT OF THE
DAY IS EXPECTED.
