MAIN CONCERN TONIGHT IS THE POSSIBILITY OF MORE RAIN FOR NORTHEAST
PARTS OF THE CWFA.

GENERALLY LIKE THE AVN THE BEST OF THE MODELS. THE UPPER LOW OVER
SOUTHEAST MISSOURI WILL SLOWLY MOVE EAST TONIGHT AND SATURDAY.
BEFORE IT GETS TOO FAR AWAY...SEVERAL SHORT WAVES WILL MOVE THROUGH
THE NORTHEAST SECTION. THIS IS GOING TO BRING MORE THUNDERSTORMS TO
THE AREA WHERE IT HAS BEEN RAINING ALL DAY TODAY. LOOKING AT THE VAD
WIND PROFILE WINDS AT THE SURFACE AND ALOFT ARE ONLY AROUND 15KTS.
THE GROUND IS SATURATED SO A FLASH FLOOD WATCH WILL BE ISSUED FOR A
PORTION OF THE NORTHEAST

SHOWERS AND THUNDERSTORMS WILL BE CONCENTRATED IN THE NORTHEAST
AGAIN TONIGHT. SCATTERED THUNDERSTORMS WILL DEVELOP ACROSS THE AREA
ON SATURDAY WITH HIGH PRESSURE ALONG THE GULF COAST. AS THE LOW
MOVES OFF TO THE EAST AND HIGH PRESSURE BUILDS OVER
ARKANSAS...SUNDAY AND MONDAY WILL BE DRY. THE NEXT FRONT MOVES INTO
THE AREA FROM THE NORTH ON TUESDAY. THIS WILL BRING A CHANCE OF
SHOWERS AND THUNDERSTORMS TO THE AREA FOR THE MIDDLE AND LATTER PART
OF NEXT WEEK.

TEMPERATURES WILL BE SIMILAR THROUGHOUT THE PERIOD WITH LOWS IN THE
70S AND HIGHS IN THE 80S AND 90S.
