.SHORT TERM (TONIGHT-THURSDAY NIGHT)...
THE LATEST NUMERICAL GUIDANCE HAS INITIALIZED WELL WITH THE
CURRENT SYNOPTIC PATTERN AND GENERALLY REMAINS IN GOOD AGREEMENT
THROUGH THE SHORT-TERM PERIOD. SIMILAR TO THE PAST COUPLE OF
EVENINGS...MOST OF THE MID TO LATE AFTERNOON HEAVY SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO SETUP OVER THE EASTERN HALF OF THE
SOUTH FLORIDA PENINSULA AND BEGIN TO IMPACT THE EAST COAST AND METRO
LOCATIONS THROUGH THE EARLY EVENING HOURS. THE MAIN IMPACTS FROM THE
STRONGER STORMS THAT DEVELOP THROUGH THIS TIME WILL BE FREQUENT
LIGHTNING...LOCALIZED FLOODING...GUSTY WINDS FROM 40-55 MPH AND
SMALL HAIL. THE LATEST HRRR AND WRF MODEL REFLECTIVITIES LINE UP
WELL WITH THIS PATTERN CONTINUING THROUGH THE MID-EVENING HOURS
BEFORE TRENDING DOWN THROUGH THE OVERNIGHT PERIOD TONIGHT.

WEDNESDAY AND WEDNESDAY NIGHT...AS BERYL CONTINUES TO LIFT NORTHEAST
TO THE CAROLINA COAST OVER THE NEXT COUPLE OF DAYS...THE MODELS
CONTINUE TO INDICATE A SHORTWAVE TROUGH DIGGING SOUTHEAST OVER THE
REGION MAINTAINING A BROAD CYCLONIC UPPER FLOW ACROSS THE AREA. AT
THE SURFACE...THE SUBTROPICAL RIDGE AXIS WILL REMAIN JUST SOUTH OF
THE LOCAL AREA WITH SOUTHWEST FLOW CONTINUING THROUGH THE
LOWER-LEVELS. THE COMBINATION OF THE UPPER TROUGH...DAYTIME HEATING
AND SUFFICIENT SURFACED BASED INSTABILITY WILL BE ENOUGH TO TRIGGER
SCATTERED SHOWERS AND STORMS EACH DAY. WITH THE PRIMARY FLOW THROUGH
THE DEEP LAYER REMAINING OUT OF THE SW...EXPECT THE BULK OF THE
AFTERNOON CONVECTION TO BECOME CONCENTRATED OVER THE EASTERN HALF OF
THE LOCAL AREA EACH DAY.

THURSDAY AND THURSDAY NIGHT...ONE DIFFERENCE TO NOTE FOR THIS PERIOD
IS THE DEEP LAYER MOISTURE THE MODELS CONTINUE TO INDICATE SPREADING
NORTH ACROSS THE KEYS AND THE SOUTH FLORIDA PENINSULA. THIS INCREASE
IN DEEP LAYER MOISTURE COMBINED WITH THE UPPER TROUGH WILL ONLY
ENHANCE THE RAINFALL COVERAGE ACROSS THE LOCAL AREA...ESPECIALLY
THROUGH THE AFTERNOON AND EVENING PERIOD THURSDAY. MODEL PWAT VALUES
REFLECT THIS PATTERN AND GENERALLY INDICATE A NORTH TO SOUTH
GRADIENT ACROSS THE AREA OR FROM THE LAKE TO THE KEYS WITH THE
HIGHER PWAT VALUES REMAINING OVER THE SOUTHERN HALF OF THIS AREA (UP
TO 2.2 INCHES). AS A RESULT...WILL GRADUALLY BEGIN TO INCREASE THE
RAINFALL CHANCES THROUGH THIS PERIOD...ESPECIALLY OVER THESE
SOUTHERN AREAS WHERE THE BEST SOURCE OF DEEP LAYER MOISTURE WILL BE.

LONG TERM (FRIDAY-WEEKEND)...
MODELS REMAIN PERSISTENT INTO THE WEEKEND AND CONTINUE INDICATE THE
PREVIOUSLY DISCUSSED DEEP LAYER MOISTURE SPREADING FARTHER NORTH
ACROSS THE AREA. THIS INCREASING DEEP LAYER MOISTURE SPREADING NORTH
INTO THE LOCAL AREA WILL TRANSLATE TO INCREASING RAINFALL CHANCES
INTO THE WEEKEND. THE LATEST HPC 5 DAY PRECIP FORECAST INDICATES
TOTALS REACHING THE 2-3 INCH RANGE ACROSS THE SOUTHERN END OF THE
PENINSULA. AS TYPICALLY OBSERVED...LOCALLY HIGHER AMOUNTS WILL BE
POSSIBLE WHERE THE BULK OF THE ACTIVITY BECOMES CONCENTRATED.

&&

.MARINE...
LIGHT TO MODERATE SOUTH AND SOUTHWEST WINDS WILL BE EXPECTED
THROUGH THE MID-WEEK PERIOD WITH ISOLATED SHOWERS AND STORMS
REMAINING POSSIBLE EACH DAY. LATE MORNING AND AFTERNOON SEA
BREEZES WILL TRANSLATE TO CHOPPIER CONDITIONS EACH DAY...MAINLY
NEAR THE COAST.

&&

.FIRE WEATHER...
PLENTY OF MOISTURE SPREADING NORTH OVER THE LOCAL AREA WILL KEEP
RELATIVE HUMIDITY VALUES ABOVE CRITICAL RED FLAG LEVELS THROUGH
THE PERIOD.
