QUIET, SUNNY, AND PLEASANT BEST DESCRIBES THE WEATHER TODAY.
TEMPERATURES ARE IN THE UPPER 70S, NEARING 80 DEGREES, DEW POINTS
IN THE LOWER TO MID 60S. MEANWHILE, A SURFACE LOW SOUTH OF THE
HUDSON BAY IS EXERTING A LARGE PRESSURE GRADIENT DOWN THE ENTIRE
EASTERN SEABOARD. THIS IS WEAKENING THE AREA OF HIGH PRESSURE
ACROSS THE REGION AND BIFURCATING IT INTO TWO CELLS. AS A RESULT
THE KEYS ARE LEFT IN A COL AND IS LEADING TO WINDS BECOMING LIGHT
AND VARIABLE.
NO CHANGES ARE NEEDED OR EXPECTED. DRY WEATHER WILL PREVAIL TODAY
UNDER LIGHT WINDS AND COMFORTABLE DEW POINTS. DAY TIME HIGHS WILL
REACH INTO THE LOWER 80S WITH PLENTY OF SUNSHINE.
MARINE

BREEZES TO BECOME LIGHT AND VARIABLE. THE DECAYING TAIL END OF A
COLD FRONT WILL CLIP THE LOCAL WATERS WEDNESDAY, BUT THE ONLY
CHANGE IN WEATHER CONDITIONS WILL BE BREEZES ASSUMING A NORTHERLY
DIRECTION. ON THURSDAY, HIGH PRESSURE REBUILDING WILL CAUSE
BREEZES TO TURN EASTERLY AND FRESHEN QUICKLY. FRESH TO STRONG
BREEZES ARE EXPECTED TO BE IN PLACE AS EARLY AS THURSDAY NIGHT,
AND THESE CONDITIONS WILL CONTINUE INTO THE START OF THE WEEKEND.
