DISCUSSION

A WEAK RIDGE STRETCHING ACROSS SOUTH FLORIDA THIS EVENING IS
DRIVING IN LIGHT MOSTLY EAST TO SOUTHEASTERLY BREEZES ACROSS THE
KEYS AREA. WEAK DEEP LAYERED RIDGING IS ROUGHLY ALIGNED ACROSS OUR
AREA. DESPITE THIS, THIS EVENINGS SOUNDING INDICATED THE PRECIPITABLE
WATER WAS VERY CLOSE TO THE MEDIAN FOR THE DAY AT 1.84 INCHES.
THERE WAS A SOME DRIER AIR AND LIMITED CAPE THROUGH THE LOWER
LEVELS. THIS AND A LACKLUSTER FORCING HAS KEPT SHOWER AND
THUNDERSTORM ACTIVITY QUITE LIMITED THROUGH THE EVENING. SURFACE
CONDITIONS ARE SEASONABLY WARM BUT UNUSUALLY DRY. DEW POINTS WERE
NEAR 70 FOR MUCH OF THE LATE AFTERNOON AND EARLY EVENING, BUT BEEN
CLIMBING IN RECENT HOURS INTO THE MID 70S.
THE RIDGE ACROSS FLORIDA WILL LIFT SLIGHTLY NORTHWARD INTO CENTRAL
FLORIDA OVERNIGHT. THIS ALONG WITH DISSIPATING DAY TIME HEATING
EFFECTS WILL LET BREEZES FIRM UP SLIGHTLY OUT OF THE EAST TO
SOUTHEAST ACROSS THE AREA. FORECAST SOUNDINGS SUGGEST THAT THE
LOWER LEVELS MAY MOISTEN SLIGHTLY WHILE BECOMING A BIT LESS
STABLE. THIS ALONG WITH THE USUAL ENHANCED NOCTURNAL CONFLUENCE
MAY BE ENOUGH TO TRIGGER A FEW CONVECTIVE CELLS LATER IN THE
NIGHT. IF WINDS REMAIN LIGHT ACROSS THE KEYS, TEMPERATURES MAY BE
ABLE TO RADIATE DOWN INTO THE LOWER 80S WITH DEW POINTS CONTINUING
TO RECOVER INTO THE MID TO UPPER 70S. NO CHANGES PLANNED THIS
EVENING.
