SHORT TERM:
DEEP-LAYERED HIGH PRESSURE REMAINS ANCHORED OVER THE WESTERN ATLANTIC, WHILE A DISTURBANCE NORTH OF SOUTH FLORIDA CONTINUES TO LIFT AWAY FROM THE REGION. GUIDANCE SUGGESTS DRIER AIR WILL FILTER INTO SOUTH FLORIDA TODAY, KEEPING PWATS SLIGHTLY BELOW CLIMATOLOGICAL NORMS AND SUPPRESSING POPS ACROSS THE EAST COAST METRO AREAS. HOWEVER, SUFFICIENT LOW-LEVEL MOISTURE AND STRONG DIURNAL HEATING WILL ALLOW SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP ALONG SEA BREEZES PUSHING INLAND THIS AFTERNOON. A MODERATE SOUTHEASTERLY STEERING FLOW WILL PUSH THE PRIMARY FOCUS OF CONVECTION FURTHER WEST, WITH THE HIGHEST POPS (40–50%) CENTERED AROUND SOUTHWEST FLORIDA AND THE LAKE OKEECHOBEE REGION.
AS THE SURFACE HIGH PRESSURE RIDGE AXIS SHIFTS SOUTHWESTWARD TOWARD THE FLORIDA PENINSULA ON SUNDAY, WINDS WILL GRADUALLY RELAX INTO A LIGHTER EASTERLY REGIME. PWATS ARE EXPECTED TO RECOVER BACK TO CLIMATOLOGICAL NORMS, GIVING WAY TO A MORE TYPICAL SUMMERTIME SEA-BREEZE PATTERN WITH HIGH PRESSURE BUILDING FIRMLY TO THE NORTH AND WINDS BACKING EASTERLY, A CLASSIC TAKES HOLD. EXPECT ISOLATED TO SCATTERED SHOWERS ALONG THE EAST COAST DURING THE MORNING HOURS, BEFORE BOUNDARY COLLISIONS AND DIURNAL HEATING SHIFT THE HIGHEST CONVECTIVE COVERAGE INLAND AND TOWARD THE GULF COAST BY THE AFTERNOON.
HIGHS WILL REACH THE LOW TO MID-90S TODAY AND SUNDAY, WITH PEAK HEAT INDICES POTENTIALLY REACHING 105-110°F ACROSS INTERIOR AND SOUTHWEST FLORIDA.
LONG TERM:
A TYPICAL SEA-BREEZE-DRIVEN CONVECTIVE PATTERN IS EXPECTED TO PERSIST THROUGH NEXT WEEK. UNDER PREVAILING EASTERLY FLOW, EARLY MORNING SHOWERS REMAIN POSSIBLE OVER THE ATLANTIC WATERS AND COASTAL AREAS EACH DAY, GIVING WAY TO SCATTERED AFTERNOON SHOWERS AND THUNDERSTORMS ACROSS THE INTERIOR AND SOUTHWEST FLORIDA.
GUIDANCE CONTINUES TO INDICATE A PLUME OF SAHARAN DUST APPROACHING SOUTH FLORIDA TOWARD THE MIDDLE OF THE WORKWEEK. THIS INFLUX OF DRIER COULD POTENTIALLY SUPPRESS OVERALL CONVECTIVE COVERAGE THROUGH FRIDAY. HEAT WILL REMAIN THE PRIMARY FORECAST CONCERN THROUGH NEXT WEEK, WITH MAXIMUM TEMPERATURES HOVERING IN THE MID-90S AND PEAK HEAT INDICES RANGING BETWEEN 100-105°F FOR MUCH OF THE REGION, EXCEPT ALONG THE IMMEDIATE ATLANTIC COAST.
MARINE:
GENTLE TO MODERATE EAST-SOUTHEASTERLY WINDS WILL PERSIST ACROSS THE LOCAL COASTAL WATERS THROUGH THE NEXT FEW DAYS. ISOLATED TO SCATTERED THUNDERSTORMS REMAIN POSSIBLE EACH DAY, WHICH MAY RESULT IN LOCALLY GUSTY WINDS AND BRIEF PERIODS OF ROUGH SEAS. OUTSIDE OF CONVECTION, SEAS WILL GENERALLY REMAIN 2 TO 3 FEET THROUGH EARLY NEXT WEEK.
