REST OF TODAY-SATURDAY...HOT AND HUMID ONCE AGAIN ACROSS EAST
CENTRAL FLORIDA THIS AFTERNOON, WITH LIMITED SHOWER COVERAGE AS OF
2 PM AND A DELAYED, WEAK EAST COAST SEA BREEZE. WIDELY SCATTERED
SHOWERS AND STORMS ARE FORECAST TO DEVELOP ALONG THE SEA BREEZE AS
IT MOVES INLAND THROUGH THIS EVENING, WITH POPS 20-40%. HOWEVER,
THIS MAY BE A BIT OVERDONE GIVEN THE WEAK CU FIELD SEEN ON VISIBLE
SATELLITE IMAGERY. REGARDLESS, MOST AREAS WILL REMAIN DRY TODAY,
WITH LITTLE RELIEF FROM SCORCHING HEAT INDICES 108-112 DEGREES. A
HEAT ADVISORY REMAINS IN EFFECT THROUGH 8 PM. ANY STORMS THAT
MANAGE TO DEVELOP TODAY WILL BE CAPABLE OF STRONG WIND GUSTS TO 50
MPH, WITH DRY AIR IN THE MID LEVELS. CONVECTION IS FORECAST TO
TAPER OFF INTO THIS EVENING OVER THE INTERIOR, WITH OVERNIGHT LOWS
IN THE MID TO UPPER 70S.
RINSE AND REPEAT TO BEGIN THE WEEKEND, AS HIGH PRESSURE PREVAILS
OVER THE FLORIDA PENINSULA. BELOW AVERAGE COVERAGE OF SHOWERS AND
STORMS CONTINUES, WITH POPS GENERALLY 20-40%. A WAVE OF SAHARAN
DUST IS FORECAST TO MOVE INTO THE AREA THROUGH SATURDAY,
INCREASING THE CHANCES FOR A FEW STRONG STORMS, WITH WIND GUSTS TO
AROUND 50 MPH. LIGHT OFFSHORE FLOW BECOMES S/SE ALONG THE COAST AS
THE SEA BREEZE DEVELOPS AND MOVES INLAND. OVERALL, WINDS REMAIN
AROUND 10 MPH OR LESS. LOW PRECIPITATION COVERAGE AND A WEAK SEA
BREEZE WILL CONTINUE TO ALLOW HIGHS TO REACH WELL INTO THE 90S.
MEANWHILE, HUMID CONDITIONS PRODUCE HEAT INDICES 108-112 DEGREES.
ADDITIONAL HEAT ADVISORIES ARE LIKELY THROUGH AT LEAST SATURDAY.
DON'T FORGET TO INTEGRATE HEAT SAFETY INTO YOUR WEEKEND PLANS!
SUNDAY-THURSDAY...BELOW NORMAL RAINFALL CHANCES, WELL BELOW NORMAL
AT TIMES, PERSIST INTO EARLY NEXT WEEK. SURFACE HIGH PRESSURE
BUILDS BACK TOWARDS THE PENINSULA AND INTO THE EASTERN GULF
THROUGH THE PERIOD. ALOFT, A STRONG UPPER LEVEL RIDGE FLATTENS
OVER THE SOUTHEAST US. OVERALL, LITTLE CHANGE TO THE PATTERN FOR
EAST CENTRAL FLORIDA. FORECAST POPS PEAK AT 20-30% OR LESS, WITH
DRY CONDITIONS EXPECTED AREA-WIDE FOR AT LEAST MONDAY. MOST AREAS
WILL LIKELY REMAIN DRY. REGARDLESS, STRONG STORMS WILL BE
POSSIBLE EACH AFTERNOON, WITH WAVES OF SAL SUPPORTING WIND GUSTS
TO 50 MPH IN STORMS THAT CAN SURVIVE THE OVERALL SUBSIDENCE. LIGHT
OFFSHORE FLOW WILL CONTINUE TO OPPOSE THE AFTERNOON SEA BREEZE,
WHICH REMAINS WEAK AT AROUND 10 MPH OR LESS. HIGHS IN THE MID-90S
WILL CREEP TOWARDS THE UPPER 90S AT TIMES, WITH HUMID CONDITIONS
CONTINUING. ADDITIONAL HEAT ADVISORIES WILL NEED TO BE CONSIDERED
THROUGH THE FORESEEABLE FUTURE.
MARINE
