.SHORT TERM...TONIGHT THROUGH SATURDAY...LONG WAVE MID LATITUDE
TROUGH, WITH A SHORT WAVE MOVING EAST AROUND ITS BASE, WILL MAKE
BOTH, THE DEEP LAYER RIDGE AND SFC ATLANTIC RIDGE, TO SHIFT EAST
OF THE AREA BRIEFLY WITH A LIGHT WEST TO SOUTHWEST FLOW DEVELOPING
AT ALL LEVELS. THIS WILL RESULT IN A SLIGHT SHIFT IN THE
CONVECTION PATTERN MORE TOWARD EASTERN PORTIONS OF SOUTH FLORIDA
THIS EVENING AND SATURDAY AFTERNOON. LIGHT SFC FLOW WILL ALLOW
SEA/BREEZES COMBINED WITH DIURNAL HEATING TO HAVE A MAJOR ROLE IN
THE FORMATION OF SHWRS/TSTMS AGAIN SATURDAY AFTERNOON. WILL
THEREFORE INDICATE SLIGHTLY HIGHER POPS TOWARD EASTERN HALF OF THE
PENINSULA SATURDAY. NO SIGNIFICANT CHANGES ARE EXPECTED IN
AFTERNOON TEMPS, EXCEPT FOR A DEGREE OR TWO HIGHER ALONG THE
EASTERN AREAS ON SATURDAY.

.LONG TERM...SUNDAY THROUGH THURSDAY...THE ATLANTIC RIDGE WILL
BUILD BACK WEST ACROSS THE PENINSULA AS THE MID LATITUDE TROUGH
LIFTS NORTHEASTWARD BY MID WEEK. ALTHOUGH MODELS INDICATE A
SLIGHTLY DRIER AIRMASS, ENOUGH MOISTURE WILL STILL BE PRESENT
DURING THIS PERIOD TO RESULT IN SCATTERED AFTERNOON SHWR/TSTM
ACTIVITY MAINLY ACROSS INTERIOR AREAS AND ISOLATED TO LOW SCT
NIGHTTIME/EARLY MORNING ACTIVITY ALONG COASTAL AREAS AND ADJACENT
WATERS.

.MARINE...GOOD BOATING CONDITIONS SHOULD PREVAIL WITH LIGHT WINDS
