DISCUSSION
(THIS EVENING THROUGH NEXT MONDAY)

WATER VAPOR SHOWS AN UPPER LEVEL RIDGE OVER THE REGION WITH DRY AND
SUBSIDENT AIR IN THE MID LEVELS. RADAR IS RATHER QUIET WITH JUST A
FEW STRAY SHOWERS SO FAR DEVELOPING OUT OF THE CU STREAKS. IT IS
SOMEWHAT HUMID WITH DEW POINTS IN THE 70S AND APPARENT TEMPERATURES
IN THE 90S.
GUIDANCE SHOWS THE UPPER LEVEL RIDGE HANGING OVER THE SOUTHERN US
FOR THE REMAINDER OF THE WEEK. MEANWHILE, SOUTHERLY FLOW AROUND A
SURFACE HIGH OF THE SOUTHEAST US COAST WILL ALSO CONTINUE.
THEREFORE, NOT MUCH CHANGE IN THE FORECAST EACH DAY. ISOLATED TO
WIDELY SCATTERED SHOWERS OR STORMS ARE EXPECTED TO FORM DURING THE
AFTERNOON HOURS WITH DAYTIME HEATING AND THE SEA BREEZE. ACTIVITY
THAT DOES FORM WILL DECREASE AT SUNSET.
WITH THE RELATIVE LACK OF CONVECTION AND THE SOUTHERLY WINDS
BRINGING IN LOW LEVEL GULF MOISTURE, IT WILL DEFINITELY FEEL LIKE
SUMMER AS THE HEAT AND MUGGINESS WILL BE INCREASING. AFTERNOON HIGHS
WILL BE IN THE 90S WITH THE MAX AFTERNOON HEAT INDEX BETWEEN 100 AND
105 DEGREES. AT NIGHT, LOWS WILL BE IN THE MID TO UPPER 70S WITH
RELATIVE HUMIDITY OVER 90%, SO DEFINITELY "STICKY."
AS WE GET TO THE END OF THE FORECAST PERIOD, THE UPPER LEVEL RIDGE
WILL BEGIN TO BREAK DOWN AND A NORTHERN STREAM SHORT WAVE WILL BEGIN
TO DIG DOWN TO THE SOUTH BRINGING A FRONTAL BOUNDARY TOWARD THE
REGION THAT IS EXPECTED TO INCREASE RAIN CHANCES.
