WEEKEND. THE SURFACE FLOW WILL BE FROM THE SOUTH AND BRING IN WARM
AND HUMID AIR. DEW POINTS WILL REMAIN IN THE 70S...SOME PLACES
WILL EVEN SEE DEW POINTS NEAR 75 OR ABOVE. WITH THESE HIGH DEW
POINTS AND THE HIGH TEMPERATURES IN THE 90S...HEAT INDEX WILL BE
ABOVE 105 IN MOST AREAS EACH AFTERNOON. THUS THE HEAT ADVISORY
WILL CONTINUE...THIS WILL BE TRUE THROUGH MONDAY. TEMPERATURES AT
NIGHT WILL NOT FALL BELOW 75 THIS WEEKEND.
MONDAY NIGHT INTO TUESDAY A WEAK FRONTAL SYSTEM MOVES INTO THE
AREA BRINGING THE CHANCE FOR SOME PRECIPITATION AND ALSO BRINGING
IN A LITTLE LESS HUMID AIR. BEHIND THE FRONTAL SYSTEM WILL BE ANOTHER
HIGH PRESSURE SYSTEM THAT WILL HAVE LESS HUMID AIR. HOWEVER...THE
MAXIMUM TEMPERATURES WILL STILL BE IN THE 90S FOR THE REST OF THE
FORECAST PERIOD. THE HIGH PRESSURE SYSTEM NEVER TAKES HOLD AND THE
MID-SOUTH REMAINS NEAR THE BOUNDARY BETWEEN THE TWO HIGHS AND WILL
MAKE FOR AN UNSETTLED PERIOD STARTING TUESDAY THROUGH THE END OF
THE FORECAST PERIOD.
