DISCUSSION
KEY MESSAGE 1... ABOVE NORMAL TEMPERATURES AND INCREASED
HUMIDITY WILL CONTINUE THROUGH MUCH OF THIS WEEK. THE POTENTIAL
FOR SHOWERS AND THUNDERSTORMS MAY PROVIDE SOME TEMPORARY RELIEF
FOR SOME AREAS EACH DAY.
ABOVE NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE THIS WEEK,
BUT THE EXTREME HEAT OBSERVED OVER THE LAST FEW DAYS SHOULD
START TO RELAX EARLY THIS WEEK. HEAT ADVISORY THRESHOLDS HAVE
BEEN MARGINAL THE LAST SEVERAL DAYS AND A DEGRADING RIDGE WILL
CONTINUE TO ALLOW TEMPERATURES TO COOL BY A COUPLE OF DEGREES
EARLY THIS WEEK. HUMIDITY WILL INCREASE IN RESPONSE TO A
BUILDING BERMUDA HIGH, BUT AFTERNOON HEAT INDICES SHOULD REMAIN
BETWEEN 100 AND 104. THE PROLONGED NATURE OF THE WARM
TEMPERATURES SHOULD BE CONSIDERED FOR ANY OUTDOOR PLANS.
AFTERNOON THUNDERSTORMS WILL REMAIN FOCUSED ALONG THE PIEDMONT
TROUGH TODAY. MORE WIDESPREAD ACTIVITY IS POSSIBLE A WEAK
TROUGH APPROACHES THE AREA MONDAY THROUGH THE MIDDLE OF THIS
WEEK. INCREASING ACTIVITY ALONG THE SEA BREEZE COULD ALSO
PROVIDE ADDITIONAL ROUNDS OF STORMS EACH DAY.

EARLY THIS AFTERNOON. AS THE SEA BREEZE DEEPENS, SKIES SHOULD
BECOME CLEAR OR CIGS SHOULD RISE ABOVE MVFR. STORMS SHOULD
