NATIONAL WEATHER SERVICE KEY WEST FL
341 PM EDT SUN MAY 5 2013

.DISCUSSION...
MODERATE NORTHWEST TO NORTH BREEZES HAVE PREVAILED TODAY ACROSS THE
FLORIDA KEYS WITH SOME ONGOING BOUNDARY-LAYER COLD THERMAL ADVECTION
EVIDENCED BY AIR TEMPERATURES REMAINING IN THE 70S FOR MOST OF THE
DAY. A STABLE WEST-NORTHWEST FLOW PREVAILS THROUGH A DEEP PORTION OF
THE TROPOSPHERE SOUTH OF A LARGE...SLOW-MOVING CUT-OFF CYCLONE OVER
THE TENNESSEE VALLEY.

THE WEATHER FOR THE NEXT SEVERAL DAYS SHOULD BE RATHER BENIGN AS A
DEEP...DRY...AND GENERALLY STABLE WESTERLY FLOW PREVAILS ALOFT. NEAR-
SURFACE TEMPERATURES WILL RE-BOUND A DEGREE EACH SUCCESSIVE DAY
ALTHOUGH OVERNIGHT LOWS MAY TOUCH 70F FOR THE NEXT FEW DAYS WHILE
WINDS AND DEWPOINTS LULL. NO SIGNIFICANT PRECIPITATION OR WEATHER IS
EXPECTED FOR SEVERAL DAYS...AND POPS HAVE BEEN REDUCED BELOW CLIMO
UNTIL THURSDAY.

SMALL CRAFT SHOULD EXERCISE CAUTION ACROSS FLORIDA KEYS COASTAL
WATERS THIS EVENING. A NORTHWEST TO NORTH WIND SURGE IS LIKELY OVER
PORTIONS OF THE WATERS ADJOINING THE KEYS THIS EVENING...WHILE A

SOUTHEASTERN GULF OF MEXICO.
