ROBUST SURFACE THROUGH MID LEVEL RIDGING STRETCHES WESTWARD FROM
THE ATLANTIC TO THE EASTERN GULF. THE SURFACE RIDGE IS RESULTING
IN GENTLE TO MODERATE EAST TO SOUTHEASTERLY BREEZES ACROSS THE
KEYS THIS EVENING. THIS EVENINGS SOUNDING INDICATED AMPLE CAPE AND
NEAR NORMAL PRECIPITABLE WATER OF 1.87 INCHES. HOWEVER, THERE WAS
WEAK LOW LEVEL INHIBITION AND LOW LEVEL INSTABILITY WAS LIMITED.
AS A RESULT, AFTER A COUPLE OF CLUSTERS OF SHOWERS AND
THUNDERSTORMS THROUGH THE AFTERNOON, THE FORECAST AREA HAS BEEN
NEARLY PRECIPITATION FREE THROUGH THE EVENING. SURFACE CONDITIONS
ARE SEASONABLE WITH TEMPERATURES IN THE MID 80S AND DEW POINTS IN
THE UPPER 70S.
THE SURFACE RIDGE ACROSS FLORIDA IS EXPECTED TO STRENGTHEN
SLIGHTLY THROUGH THE OVERNIGHT PERIOD. THIS, ALONG WITH THE USUAL
EVENING SUBTLE WIND SURGE WITH THIS SYNOPTIC SETUP, SHOULD RESULT
IN EAST TO SOUTHEASTERLY BREEZES STRENGTHENING FURTHER THROUGH THE
OVERNIGHT PERIOD. LOWER LEVEL INSTABILITY ALONG WITH THE ARRIVAL
OF A SWATH OF DRIER LOWER LEVEL AIR SHOULD HELP TO LIMIT
CONVECTIVE ACTIVITY. WILL MAINTAIN SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS. EXPECT OVERNIGHT LOWS IN THE LOWER TO MID 80S WITH
DEW POINTS REMAINING IN THE UPPER 70S.
