AREA FORECAST DISCUSSION

DISCUSSION
A MULTITUDE OF OUTFLOW AND SEA/LAKE BREEZE INTERACTIONS THIS
AFTERNOON RESULTED IN SCATTERED COVERAGE OF STORMS FROM THE ORLANDO
METRO SOUTHWARDS. MOST ACTIVITY HAS DIMINISHED WITH SUNSET...WITH
THE EXCEPTION OF A LATE DAY EAST AND WEST COAST SEA BREEZE COLLISION
OVER LAKE...WESTERN VOLUSIA...SEMINOLE...AND ORANGE COUNTIES. ISOLD
SHOWERS AND POSSIBLY A THUNDERSTORM WILL LINGER A LITTLE LONGER OVER
VOLUSIA COUNTY UNTIL JUST BEFORE MIDNIGHT. CLOUD COVER WILL DECREASE
AS THE NIGHT WEARS ON BUT SHOULD STILL REMAIN PARTLY CLOUDY. A FEW
AREAS COULD SEE A LITTLE PATCHY FOG TOWARDS SUNRISE...BUT DON'T
THINK THE COVERAGE WILL BE WIDESPREAD ENOUGH TO MENTION IN THE
ZONES. LOWS WILL BE IN THE LOW/MID 70S.
FROM PREVIOUS DISCUSSION...
SUNDAY...DRIER AIR WILL CONTINUE TO FILTER IN FROM THE NORTH SUNDAY
WITH INCREASING MOISTURE OVER THE SOUTH. SOUTHWEST FLOW WILL BEGIN
TO INCREASE INTO THE AFTERNOON BTW AN AREA OF LOW PRESSURE AND
ASSOCIATED FRONTAL BOUNDARY THAT WILL PUSH INTO THE SOUTHEAST U.S.
AND THE HIGH PRESSURE RIDGE AXIS SOUTH OF THE AREA. STRENGTHENING SW
FLOW SHOULD PROHIBIT SEA BREEZE DEVELOPMENT NORTH OF THE CAPE WITH
ONLY A SLIGHT INLAND MOVEMENT FARTHER SOUTH (IF IT EVEN DEVELOPS AT
ALL). CONVECTION WILL BE MORE ISOLATED NORTH OF ORLANDO WHERE DRIER
AIR WILL EXIST WITH SCATTERED SHOWERS/STORMS SOUTH. TEMPS LOOK TO BE
HIGHEST OVER THE NORTHERN INTERIOR WHERE LACK OF CONVECTION AND NO
RELIEF FROM THE SEA BREEZE WILL ALLOW HIGHS TO REACH THE MID 90S
WITH HEAT INDEX VALUES NEAR 100-105 DEGREES. ALONG THE COAST AND
OVER THE SOUTH TEMPS WILL BE IN THE LOW 90S.
AVIATION
LATE DAY SEA BREEZE COLLISION AND OUTFLOW INTERACTIONS
WILL BRING TEMPO MVFR SHRA IN VCNTY KMCO/KORL AND KVRB/KFPR THROUGH
02Z. OTHERWISE...PREVAILING VFR. MAY ALSO SEE SOME PATCHY FOG
DEVELOP LATE TONIGHT WITH BRIEF PERIODS OF VISIBILITIES FROM 3-5 SM.
