AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
255 PM EDT THU APR 28 2016

.DISCUSSION...
CURRENTLY - A SURFACE RIDGE EXTENDS ACROSS CENTRAL
FLORIDA...RESULTING IN GENTLE EAST TO SOUTHEAST BREEZES ACROSS THE
FLORIDA KEYS AND SURROUNDING WATERS. ONLY A FEW VERY WEAK SHOWERS
HAVE BEEN DETECTED BY LOCAL RADARS...MAINLY ALONG MARINE CLOUD LINES
OVER THE FLORIDA STRAITS. TEMPERATURES ARE IN THE MID 80S WITH DEW
POINTS HOLDING NEAR 70.

FORECAST - THE RIDGE AXIS OVER CENTRAL AND SOUTH FLORIDA WILL LOOSEN
OVER THE NEXT COUPLE OF DAYS WHILE PRESSURES FALL IN THE WESTERN GULF
OF MEXICO. IN GENERAL...WINDS WILL MAINTAIN A GENTLE EAST TO
SOUTHEAST BREEZE...USUALLY PEAKING OVERNIGHT...AND LULLING IN THE
AFTERNOON. RAIN CHANCES WILL REMAIN SLIM TO NONE AS WEAK MID TO
UPPER LEVEL RIDGING HOLDS ACROSS THE AREA. EXPECT NEAR NORMAL HIGHS
AND LOWS NEAR TO SLIGHTLY ABOVE NORMAL. DEW POINTS WILL REMAIN NEAR
70 DEGREES.

THE COMBINATION OF THE WEAK RIDGE BACKING OFF TO OUR NORTH AS IT IS
REINFORCED BY A CONTINENTAL HIGH...AND LOWER PRESSURES IN THE
WESTERN GULF OF MEXICO WILL STRENGTHEN WINDS SOMEWHAT SATURDAY NIGHT
INTO SUNDAY...BUT NOT QUITE REACHING BREEZY. LOWER LEVEL RIDGING WILL
CONTINUE TO LIMIT SHOWER ACTIVITY DESPITE THE SUBTLE WIND SURGE.

THROUGH THE FIRST HALF OF NEXT WEEK...A TROUGH WILL MOVE THROUGH THE
EASTERN UNITED STATES...WEAKENING THE RIDGE AXIS ACROSS FLORIDA. IN
RESPONSE...EAST TO SOUTHEAST BREEZES WILL RELAX BECOMING LIGHT. RAIN
CHANCES WILL REMAIN SLIM THROUGH THE PERIOD DUE TO THE WEAKER FLOW
AND WEAK BUT PERSISTENT MID LEVEL RIDGING. EXPECT NEAR NORMAL
TEMPERATURES AND A SLIGHT CHANCE AT BEST FOR PRECIPITATION.

&&

.MARINE...
A RIDGE AXIS WILL REMAIN ACROSS CENTRAL AND SOUTH FLORIDA TONIGHT
INTO THIS WEEKEND...HOLDING GENTLE TO MODERATE EAST TO SOUTHEAST
BREEZES. WINDS ARE EXPECTED TO SURGE A BIT LATE SATURDAY INTO EARLY
SUNDAY AS THE RIDGE TO OUR NORTH IS REINFORCED BY ANOTHER HIGH
FURTHER NORTH AND LOWER PRESSURE DEVELOPED IN THE WESTERN GULF OF
MEXICO. A CAUTION MAY BE REQUIRED FOR PORTIONS OF KEYS WATERS
SATURDAY NIGHT INTO SUNDAY. WINDS WILL THEN RELAX THROUGH THE FIRST
HALF OF NEXT WEEK AS THE RIDGE TO OUR NORTH WEAKENS.
