A MID THROUGH UPPER LEVEL RIDGE CENTERED OVER THE GULF STRETCHES
EASTWARD ACROSS THE FLORIDA PENINSULA. MEANWHILE, A LOWER LEVEL
ATLANTIC RIDGE EXTENDS WESTWARD ACROSS FLORIDA INTO THE GULF. AN
A MODEST PRESSURE GRADIENT ACROSS OUR AREA IS RESPONSIBLE FOR LIGHT
TO GENTLE BREEZES ACROSS THE KEYS THIS EVENING. THIS EVENINGS
SOUNDING INDICATED HEALTHY MOISTURE WITH JUST OVER 2 INCHES OF
PRECIPITABLE WATER. THERE WAS MODEST CAPE AND VERY WEAK
INHIBITION. HOWEVER, DOMINANT ANTICYCLONIC FLOW AT ALL LEVELS HAS
KEPT SHOWER ACTIVITY AT A MINIMUM THROUGH THE EVENING AND THERE
WERE NO THUNDERSTORMS.
EXPECT THE PRESSURE GRADIENT TO FLATTEN SLIGHTLY OVERNIGHT
ALLOWING WINDS TO SLACKEN TO A LIGHT BREEZE. WHILE SHOWER AND
THUNDERSTORM CHANCES CANNOT BE ABSOLUTELY RULED OUT, CHANCES WILL
BE SLIGHT AT BEST. THIS IS DUE TO MOISTURE REMAINING RELATIVELY
HIGH WITH CAPE REMAINING SUFFICIENT WITH LIMITED INHIBITION. THIS
SHOULD ALLOW FOR SOME ACTIVITY TO DEVELOP DURING THE PEAK OF
NOCTURNAL CONFLUENCE. OVERNIGHT LOWS WILL SETTLE BROADLY NEAR 80
WITH DEW POINTS REMAINING STUCK IN THE UPPER 70S.
