AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
256 AM CDT TUE JUL 22 2008

.SHORT TERM...IT WAS WARM AND MUGGY ACROSS THE MID STATE THIS
MORNING, WITH TEMPERATURES HANGING IN THE 70S.

EARLY MORNING RADAR LOOPS SHOWED A WELL-DEFINED OUTFLOW BOUNDARY,
SWUNG OUT FROM CONVECTION OVER EASTERN MISSOURI AND SOUTHERN
ILLINOIS, PUSHING INTO THE PADUCAH AREA. THIS WILL LIKELY BECOME A
FOCUS FOR ADDITIONAL CONVECTION JUST TO OUR NORTHWEST LATER THIS
MORNING, WHICH SHOULD WORK ITS WAY INTO NORTHWESTERN MIDDLE
TENNESSEE BY THIS AFTERNOON. IN ADDITION, EXPECT THE LIKELIHOOD
FOR MCS GENERATION IN THE SOUTHEAST MISSOURI AREA THIS AFTERNOON,
WITH THUNDERSTORMS SURGING TO THE EAST SOUTHEAST TOWARD THE MID
STATE. BELIEVE THIS ACTIVITY WILL LIKELY SPREAD ACROSS OUR
FORECAST AREA TONIGHT, ESPECIALLY NORTHERN SECTIONS, AS COLD FRONT
WORKS SOUTHWARD ACROSS KENTUCKY. SPC OUTLOOK INDICATES A SLIGHT
RISK FOR SEVERE THUNDERSTORMS IN MIDDLE TENNESSEE TODAY AND
TONIGHT, AND WOULD NOT BE SURPRISED TO SEE A FEW SEVERE STORMS IN
OUR AREA ON WEDNESDAY AS WELL (ESPECIALLY OVER OUR EXTREME
SOUTHERN AREAS, AHEAD OF THE COLD FRONT). WILL LEAVE MENTION OF
POSSIBILITY OF SEVERE IN ZFP FORECAST FOR LATE TODAY AND TONIGHT,
BUT LEAVE IT OUT FOR WEDNESDAY FOR RIGHT NOW AND GIVE DAY SHIFT A
CHANCE TO LOOK AT THAT POSSIBILITY A LITTLE CLOSER.

WILL ALSO MENTION HEAVY RAINFALL POTENTIAL WITH THUNDERSTORMS TONIGHT,
AS PWS AHEAD OF COLD FRONT WILL BE CLOSE TO TWO INCHES.

BRIEF REPRIEVE FROM THE HOT AND STICKY WEATHER, BEHIND THE FRONT,
WILL COME TO AN END BY FRIDAY AS FLOW TURNS BACK TO THE SOUTH AND
THE HIGHER DEW POINTS RETURN.

AS FAR AS TEMPERATURES GO, IT LOOKS LIKE ONE MORE DAY OF HEAT
INDICES AROUND 100 TODAY, AND MAY MENTION HEAT INDICES IN A
HEADLINE JUST TO KEEP EVERYONE AWARE OF HEAT-RELATED HEALTH ISSUES.

.LONG TERM...OUR SUMMER OF COLD FRONTS CONTINUES INTO EARLY NEXT
WEEK, AS YET ANOTHER COLD FRONT IS PROGGED TO DROP INTO OUR NECK
OF THE WOODS BY MONDAY OR TUESDAY.
