.DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS MOST OF
THE MIDSOUTH THIS AFTERNOON. TEMPERATURES ARE RANGING IN THE MID 70S
WHERE RAIN AND CLOUD COVER HAS PERSISTED THROUGH MUCH OF THE DAY
TO THE LOWER 90S ACROSS NORTHEAST MISSISSIPPI WHERE SUNSHINE
CONTINUES. CONVECTION SHOULD CONTINUE THROUGH THE EVENING HOURS
ACROSS MUCH OF THE MIDSOUTH WITH THE BEST CHANCE ACROSS AREAS
EAST OF INTERSTATE 55. MUCH OF THE ACTIVITY WILL DIE OFF AFTER
MIDNIGHT BUT A FEW LINGERING SHOWERS MAY STILL BE PRESENT. LOW
TEMPERATURES WILL ONLY FALL TO THE LOWER 70S TONIGHT AS SOUTHERLY
WINDS CONTINUE AND PATCHY FOG DEVELOPS.

AN UPPER LEVEL DISTURBANCE WILL MOVE JUST NORTH OF THE AREA ON
FRIDAY BRINGING ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS TO
THE AREA. ONCE AGAIN THE BEST CHANCE FOR STORMS LOOKS TO BE ACROSS
AREAS EAST OF THE MISSISSIPPI RIVER. LARGE UPPER TROUGH WILL BEGIN
TO MOVE ACROSS THE GREAT LAKES REGION AS A SURFACE COLD FRONT
APPROACHES FROM THE NORTH ON SATURDAY. MOST OF THE AREA WILL
REMAIN DRY SATURDAY BUT AS THE COLD FRONT SINKS SOUTH...SHOWERS AND
THUNDERSTORMS WILL INCREASE IN COVERAGE SATURDAY NIGHT AND SUNDAY.
UPPER TROUGH WILL DIG FURTHER SOUTH ACROSS THE OHIO VALLEY ON
SUNDAY ALLOWING THE COLD FRONT TO MOVE THROUGH THE AREA AND
COMPLETELY EXIT THE MIDSOUTH BY SUNDAY NIGHT.

MONDAY THROUGH THURSDAY...DRY AND MORE PLEASANT CONDITIONS WILL
CONTINUE AS DEWPOINTS WILL REMAIN GENERALLY IN THE UPPER 60S.
MODELS AGREE IN BUILDING A STRONG UPPER RIDGE INTO THE MIDSOUTH
THROUGH THURSDAY KEEPING THE AREA DRY. BY WEDNESDAY NIGHT...
SURFACE HIGH PRESSURE OVER THE OHIO VALLEY WILL PUSH NORTHEAST
ALLOWING A MORE SOUTHEASTERLY FLOW ACROSS THE MIDSOUTH BRINGING
DEWPOINTS UP SLIGHTLY.
