DISCUSSION

CURRENT-TONIGHT...ONE MORE DAY WITH ONSHORE-MOVING SHOWERS (ISOLD
LIGHTNING STORM) DURING THE MORNING, WITH ACTIVITY FAVORING THE
INTERIOR (ESP SOUTH OF ORLANDO) INTO THE AFTERNOON. COVERAGE MAY BE
LESS THAN PREVIOUS DAYS, WITH DEEPEST MOISTURE CONFINED TOWARD LAKE
OKEE, AND PRIMARY STORM IMPACTS OF LIGHTNING STRIKES, GUSTY WINDS
LOCALLY, AND HEAVY DOWNPOURS. STORM MOTION WILL REMAIN SLOW/ERRATIC.
BY EARLY/MID EVENING, MOST OF THE ACTIVITY SHOULD BE ACROSS WCFL &
SWFL. MOSTLY DRY CONDITIONS OVERNIGHT AS ONSHORE FLOW/CONVERGENCE
WILL BE LIGHT/WEAK.
WIDESPREAD MODERATE TO ISOLATED MAJOR HEATRISK WITH MAX TEMPS IN THE
U80S L90S (INLAND). PEAK HEAT INDICES MOSTLY IN THE U90S TO L100S,
BUT COULD SEE UP TO AROUND 105F SURROUNDING LAKE OKEE AND MARTIN
COUNTY. WARM & HUMID AT NIGHT WITH LOWS IN THE L-U70S.
FRI-SUN...GENERALLY LIGHT SURFACE WINDS VEER MORE SE/S/SSW AS A WEAK
PRESSURE GRADIENT EXISTS THRU THIS PERIOD. MID-LEVEL TEMPS
RELATIVELY WARM -4.5C TO -5.0C TO BEGIN THE PERIOD, BUT GRADUALLY
COOL TO -6.0C TO -7.0C SAT/SUN. A FEW MID-LEVEL IMPULSES WILL AID
CONVECTION OVER THE WEEKEND. HIGHER MOISTURE VALUES ACROSS SOUTH-
CENTRAL FL ON FRI SURGE NORTH ACROSS CENTRAL FL SAT/SUN. STORM
STEERING FORECAST LIGHT SOUTHERLY BUT DIURNAL BOUNDARY COLLISIONS
MAY MAKE CELL MOVEMENT ERRATIC AT TIMES AS THE ECSB WILL DEVELOP
EACH AFTERNOON AND MARCH WELL INLAND. SCT-NMRS (30-70%) SHOWERS AND
STORMS FORECAST FRI AFTN/EVENING; HIGHEST SOUTH OF ORLANDO WHERE
MOISTURE IS DEEPEST. CONTINUE TO ADVERTISE NMRS (CAPPED AT 70%)
CONVECTIVE CHANCES SAT/SUN, THOUGH BELIEVE SOME OF THESE (NBM)
NUMBERS MAY BE TOO HIGH. ACTIVITY WILL DIMINISH THRU THE EVENING AND
HOPEFULLY IN TIME NOT TO HAMPER HOLIDAY WEEKEND CELEBRATIONS.
LOCALLY HEAVY RAINFALL WILL REMAIN A KEY CONCERN IN ADDITION TO
LIGHTNING STRIKES, AND GUSTY WINDS.
TYPICAL WARM & HUMID SUMMERTIME CONDITIONS CONTINUE WITH HIGHS IN
THE U80S TO L90S, THOUGH COULD SEE SOME M90S ESP ACROSS THE I-4
CORRIDOR. PEAK HEAT INDICES ANYWHERE FROM 100-107F, STAYING FOR THE
MOMENT JUST BELOW HEAT ADVISORY CRITERIA, BUT YET WIDESPREAD
MODERATE TO MAJOR HEATRISK. CONDITIONS AT NIGHT REMAIN WARM AND
MUGGY. IF YOU ARE PLANNING TO SPEND TIME OUTDOORS, TAKE PLENTY OF
BREAKS IN THE SHADE OR A/C AND STAY WELL-HYDRATED TO AVOID HEAT-
RELATED FATIGUE/ILLNESS. NEVER LEAVE PETS OR CHILDREN IN VEHICLES
UNATTENDED!
MON-WED...WEAK ATLC RIDGING EXTENDS ACROSS THE CENTRAL FL PENINSULA
DURING THIS TIME. GENERALLY SW FLOW AT NIGHT/MORNING PERIODS,
"BACKING" ONSHORE EACH AFTERNOON WITH SEA BREEZE FORMATION AND LATE
DAY BOUNDARY COLLISIONS ACROSS THE INTERIOR. AMPLE MOISTURE WILL
CONTINUE ACROSS THE REGION FOR SCT TO LOCALLY NMRS DIURNAL
CONVECTION EACH DAY/EVENING. MAX TEMPS CONTINUE ABOVE NORMAL IN THE
L-M90S WITH PEAK HEAT INDICES PICKING BACK UP TO 100-107F EACH
AFTERNOON AHEAD OF SEA BREEZES AND PRECIP. WIDESPREAD MODERATE TO
MAJOR HEATRISK EXPECTED. LOWS REMAIN CONSISTENT IN THE 70S WITH
CONDITIONS HUMID.
