...HOT THROUGH WEDNESDAY...FOLLOWED BY INCREASING RAIN CHANCES INTO
THIS WEEKEND...

CURRENTLY/TONIGHT...BEST RAIN CHANCES WILL CONTINUE TO BE NEAR LAKE
OKEECHOBEE THROUGH LATE AFTERNOON WITH LAKE/SEA BREEZE COLLISIONS.
AS THE EAST AND WEST COAST SEA BREEZE COLLIDE TOWARD ORLANDO AND FAR
INTERIOR COULD SEE ADDITIONAL SHOWERS/STORMS DEVELOP TOWARD SUNSET.
THIS CONVECTION SHOULD END EARLY THIS EVENING WITH SKIES BECOMING
MOSTLY CLEAR AFTER MIDNIGHT AND TEMPS FALLING INTO THE LOW/MID 70S.

TUESDAY...HIGH PRESSURE RIDGE AXIS OVER LAKE OKEECHOBEE WILL SHIFT
NORTHWARD AND OVER CENTRAL FLORIDA. THE EAST COAST SEA BREEZE SHOULD
DEVELOP EARLY IN THE AFTERNOON AND MOVE INLAND THROUGH THE REMAINDER
OF THE DAY UNDER A MORE EAST/SOUTHEAST LOW LEVEL FLOW. LINGERING
DRIER AIRMASS AND DEEP LAYER SUBSIDENCE OVER THE AREA WILL KEEP RAIN
CHANCES LOW TUESDAY.  WILL KEEP JUST A SLIGHT CHANCE FOR AFT SHOWERS
AND THUNDERSTORMS MAINLY OVER THE INTERIOR...ALONG AND AHEAD OF THE
SEA BREEZE BOUNDARY. HIGHS WILL CONTINUE TO REACH MID/UPPER 90S OVER
THE INTERIOR AND LOW 90S ALONG THE COAST.

WED...COVERAGE OF SHRA/TSRA REMAINS LOW GIVEN RATHER MIDDLING MEAN
PWAT VALUES (1.4" TO 1.5") AND RATHER WARM/SUPPRESSED MID/UPPER LVLS
COURTESY OF THE DEEP LYR HIGH PRESSURE RIDGE OVER THE REGION. THE
SURFACE RIDGE AXIS WILL REMAIN OVER THE SOUTH CENTRAL PENINSULA WITH
A WEAK PRESSURE PATTERN/WIND FIELDS WEAK. POPS WILL BE LIMITED TO
SLIGHT CHC AFTN SHRA/TS ALONG SEA AND LAKE BREEZE BOUNDARIES...
MAINLY INTERIOR AND AREAS NEAR LAKE OKEECHOBEE. TEMPS REMAIN ABOVE
NORMAL...WITH MID 90S INTERIOR...EVEN A FEW UPPER 90S AND NR 90/LWR
90S NEAR THE EAST COAST BEFORE SEA BREEZE ONSET.

THU-NEXT MON (MODIFIED PREV)...PATTERN TRANSITIONS LATE WEEK AS
RIDGE ALOFT IS DISPLACED SOUTHEASTWARD. THIS OCCURS AS A MID LVL
SHORT WAVE TROUGH AND ATTENDANT SFC SYSTEM TRACKS EWD ACROSS THE
MIDWEST/GREAT LAKES WITH TROUGHINESS ALOFT EXTENDING INTO THE SE
STATES. MOISTURE DEEPENS OVER THE AREA WITH PWATS FORECAST TO RISE
AT OR ABOVE 2.0" INCHES FROM FRI ONWARD. COVERAGE OF PRECIP IS
EXPECTED TO INCREASE AS THIS OCCURS AND RIDGE AXIS SETTLES BACK
SOUTH OF CTRL FL. CHANCE/SCATTERED POPS FROM THURSDAY INTO THE
WEEKEND. FCST CONTINUES TO INDICATE 30/40 POPS EACH DAY...AND MAY
EVEN NEED TO RAISE SOME FOR FRI-SUN. TEMPS EXPECTED TO TREND DOWN
CLOSER TO CLIMO NORMS GIVE THE HIGHER POPS/MORE CLOUDS...WITH MAXES
IN THE UPPER 80S/NR 90 COAST AND LOWER 90S INLAND.

&&

.AVIATION...VFR CONDS GENERALLY EXPECTED. BEST RAIN CHANCES TO
REMAIN NEAR LAKE OKEECHOBEE. HOWEVER A LATE DAY SEA BREEZE COLLISION
OVER THE INTERIOR MAY ALLOW FOR ISOLATED CONVECTION FARTHER NORTH
TOWARD ISM/MCO/SFB AROUND 00Z. WILL KEEP OUT OF TAFS FOR NOW AS RAIN
CHANCES REMAIN QUITE LOW.

&&

.MARINE...HIGH PRESSURE RIDGE AXIS WILL LIFT NORTHWARD OVER CENTRAL
FLORIDA INTO TUESDAY. WINDS WILL BECOME SOUTHWEST AROUND 5 TO 10 KTS
TONIGHT AND THEN SOUTH/SOUTHEAST TOMORROW AS SEA BREEZE MOVES
INLAND. SEAS WILL REMAIN AROUND 1-2 FT.

WED-SAT...SURFACE HIGH PRESSURE RIDGE AXIS WILL MEANDER OVER THE
CTRL AND SOUTHERN PENINSULA NEXT SEVERAL DAYS. WIND FIELDS WILL BE
RELATIVELY LIGHT-MDT S-SW ~10-15KT...BECOMING ONSHORE NEAR THE COAST
EACH AFTERNOON. SEAS AOB 3FT...MAYBE CLOSE TO 4FT OUT TWD 50-60NM
OFFSHORE

&&

FIRE WEATHER...HIGH PRESSURE RIDGE AXIS WILL LIFT NORTH ACROSS
CENTRAL FLORIDA TOMORROW. SOUTHERLY FLOW AROUND 5 TO 10 MPH IN THE
MORNING WILL BECOME EAST TO SOUTHEAST AROUND 10 MPH AS THE EAST
COAST SEA BREEZE MOVES INLAND IN THE AFTERNOON. HOT TEMPS AND DRIER
AIR WILL ALLOW FOR RH VALUES TO FALL INTO THE RANGE OF 35-40 PERCENT
OVER THE INTERIOR AGAIN ON TUESDAY.

WED-SAT...HOT DAYTIME TEMPS AND RAIN CHANCES AOB 20 PERCENT WED WILL
ALLOW SOME MIN RH VALUES TO REACH 35-40 PCT OVER THE INTERIOR IN THE
AFTERNOON. BY THU-FRI...INCREASING MOISTURE LEVELS WILL BRING INCRS
IN CLOUD COVER/HIGHER COVERAGE OF SHRA/TS LIMITING MIN AFTN RH VALS.
