AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
320 PM CDT WED JUN 21 2006

THE MIDSOUTH IS CURRENTLY ON THE NORTHWESTERN PART OF A HIGH
PRESSURE CENTER OVER THE EASTERN UNITED STATES. ALSO...A FRONT
LIES FROM IA TO THE TX PANHANDLE. BOTH OF THESE FEATURES WILL
MOVE TO THE SOUTHEAST OVERNIGHT AND INTO THURSDAY. BY THURSDAY
AFTERNOON...THERE SHOULD BE ENOUGH MOISTURE TO ALLOW A CHANCE OF
THUNDERSTORMS THAT WILL LAST INTO EVENING. A LOW WILL FORM ON THE
FRONT THURSDAY NIGHT. THIS LOW WILL BE IN SOUTHERN MO BY FRI
MORNING. THE LOW WILL MOVE TO THE MEM AREA BY FRI EVENING. THIS
PATTERN SHOULD GIVE US A FAIRLY DECENT CHANCE OF RAIN FRIDAY.

NEXT...THE LOW WILL NOT MOVE MUCH FRIDAY NIGHT. THIS WILL KEEP
SHOWER CHANCES ALIVE DURING THE NIGHT. AS THE LOW SETTLES FARTHER
SOUTH SATURDAY AND HIGH PRESSURE FILLS IN FROM THE NORTHEAST...
EXPECT SHOWERS AND TRWS TO DIMINISH IN NORTHWESTERN COUNTIES OF
THE CWA. ONLY SOUTHEASTERN COUNTIES WILL HAVE A CHANCE OF
PRECIPITATION SATURDAY NIGHT AND SUNDAY.

SUNDAY NIGHT THROUGH WEDNESDAY...HIGH PRESSURE FROM THE GREAT
LAKES TO THE MIDSOUTH SHOULD KEEP IT DRY. TEMPS SHOULD NOT BE AS
HIGH AND HUMIDITY SHOULD BE A LITTLE LOWER.
