AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KEY WEST FL
1005 AM EDT MON OCT 26 2015

.DISCUSSION...
.CURRENTLY... UNDER MOSTLY SUNNY SKIES WITH EAST TO SOUTHEAST WINDS
OF 15 TO 20 MPH...TEMPERATURES ARE IN THE LOWR TO MID 80S ALONG THE
ISLAND CHAIN. MEANWHILE...LOCAL RADARS ARE DETECTING ONLY A FEW
SHOWERS ON THE OUTER WATERS BEYOND 50 NM SOUTH OF THE MIDDLE KEYS.
SURFACE WISE...AN EXPANSIVE SURFACE RIDGE EXTENDS OVER THE EASTERN
UNITED STATES...AND DOWN THE FLORIDA PENINSULA AND ACROSS OUR AREA.
WINDS ARE EAST TO SOUTHEAST RANGING BETWEEN 15 TO 20 KNOTS ON OUR
MARINE DISTRICT. OTHERWISE...OUR MORNING SOUNDING REVEALS PLENTY OF
MOISTURE (PWAT 1.52 INCHES) BELOW AN ISOTHERMAL LAYER NEAR 700
MB...BUT WITH CONSIDERABLE DRY AIR ABOVE. MODERATE TO FRESH
SOUTHEAST TO SOUTH WINDS UNDERNEATH THE STABLE LAYER...BECOME
VARIABLE ABOVE.

.REST OF TODAY...SIGNIFICANT MID AND UPPER LEVEL SUBSIDENCE ABOVE
700 MB COMBINED WITH DRIER AIR MIXING DOWNWARD INTO THE BOUNDARY
LAYER WILL LIMIT SHOWER ACTIVITY. CONSIDERABLE INSOLATION WITHIN A
MODERATE SOUTHEAST WIND WILL ALLOW HIGH TEMPERATURES TO CLIMB INTO
THE MID 80S. HAVE ALREADY UPDATED THE PUBLIC ZONE FORECAST TO REMOVE
TRANSITIONAL WORDING WITH ONLY DIME POPS IN THE GRIDS.
