DISCUSSION

A FAIRLY AMPLIFIED MID LATITUDE TROUGH COMPLEX REACHES DOWN INTO
FLORIDA AND HAS CONTRIBUTED TO LOWER LEVEL TROUGHING ACROSS
FLORIDA AND A SURFACE LOW RACING NORTHEASTWARD OFF THE MID-
ATLANTIC COAST. MODERATE WESTERLIES HAVE BUILT IN ACROSS THE KEYS.
CONDITIONS REMAIN WARM AND HUMID WITH TEMPERATURES IN THE LOWER
80S AND DEW POINTS IN THE MID 70S. THIS EVENINGS SOUNDING
INDICATED PRECIPITABLE WATER WAS SLIGHTLY ABOVE THE 75TH
PERCENTILE AND VIRTUALLY UNCAPPED. HOWEVER, THERE WAS A
SUBSTANTIAL DRY LAYER BETWEEN ROUGHLY 500 AND 700 MB. WIDELY
SCATTERED ACTIVITY ALONG MARITIME BOUNDARIES AND A REVERSE CLOUD
LINE HAVE LARGELY STRUGGLED TO AMOUNT TO MUCH.
THE SURFACE TROUGH IS VERY SLOWLY DRAGGING ITSELF EASTWARD ACROSS
FLORIDA, EVEN AS THE PARENT LOW IS RACING OFF TO THE NORTHEAST.
THIS WILL KEEP MODERATE WESTERLIES ACROSS THE KEYS. EVENTUALLY
DRIER AIR WILL WRAP AROUND THE TROUGH, BUT FOR TONIGHT, EXPECT DEW
POINTS TO REMAIN IN THE LOWER TO MID 70S. OVERALL, THE ENVIRONMENT
WILL REMAIN UNCAPPED WITH A PERSISTENT LOWER TO MID LEVEL DRY
LAYER. THIS SHOULD CONTINUE TO SUPPORT ISOLATED TO SCATTERED
ACTIVITY THROUGH THE NIGHT. EXPECT OVERNIGHT LOWS TO SETTLE NEAR
80.
MARINE

A SURFACE TROUGH IS LUMBERING SLOWLY EASTWARD ACROSS FLORIDA. THIS
IS RESULTING IN MODERATE WESTERLY BREEZES ACROSS THE KEYS THIS

SCATTERED FAST MOVING SHOWERS MAY DELIVER A BRIEF SHOT OF HEAVY
DOWNPOURS, AND WIND GUSTS NEAR 25 KNOTS.
