..ISOLATED EARLY EVENING THUNDERSTORMS
..HIGH DISPERSION TODAY
DISCUSSION
WHILE CANNOT ENTIRELY RULE OUT THUNDERSTORMS THIS
EVENING, THERE SHOULD BE FAR LESS COVERAGE NEAR THE FIRE AND
ACROSS THE OKEFENOKEE TODAY. THE GULF AND ATLANTIC SEA BREEZE ARE
EXPECTED TO MERGE OVER THE NWR THIS EVENING, WHICH MAY CREATE A
LIGHT, SWIRLING TYPE OF WIND AT TIMES AFTER 1900. THROUGH MOST OF
THE DAY, EXPECT A PRIMARILY SOUTHERLY WIND WITH PEAK SPEEDS AROUND
10 MPH AND OCCASIONAL GUSTS TO 15 MPH. BEING HOT, HUMID, AND
UNSTABLE (DEEPER MIXING), IT'LL CERTAINLY FEEL QUITE HOT OUT
THERE FOR THE BOOTS ON THE GROUND AS HEAT INDEX LIKELY PUSHES TO
AROUND 100 DEGREES THIS AFTERNOON.
WEDNESDAY AND THURSDAY WILL FEATURE INCREASING CHANCES FOR
THUNDERSTORMS BUT THE BEST POTENTIAL FOR STRONG AND NUMEROUS
STORMS ARE LIKELY TO BE EAST, TOWARD I-95 BOTH DAYS.
