SHORT TERM (TODAY-SATURDAY)...

RECENTLY ANIMATED WATER VAPOR LOOP SHOWED A POSITIVELY-TILTED TROUGH
EXTENDING NE-SW FROM THE GREAT LAKES TO THE BAJA PENINSULA AND
RIDGING ORIENTED FROM NE-SW FROM THE WESTERN ATL TO THE SWRN GULF OF
MEXICO. AS PLENTY OF MID TO UPPER MOISTURE SPILLS NEWD BETWEEN THESE
TWO UPPER FEATURES WNW OF THE LOCAL AREA, AN ABUNDANCE OF DRY MID-
LEVEL AIR AND SUBSIDENCE ASSOCIATED WITH THE UPPER RIDGE WILL
SUPPORT ABOVE AVERAGE TEMPERATURES AND LIMITED RAINFALL CHANCES
LOCALLY TODAY. THE LATEST HIRES MODEL OUTPUT...HOWEVER...DOES
INDICATE A FEW SHOWERS DEVELOPING OVER THE INTERIOR AREAS AS A GULF
COAST SEA BREEZE DEVELOPS AND PENETRATES INLAND THIS AFTERNOON. THE
SHORT-RANGE MODEL GUIDANCE HAS INITIALIZED WELL WITH THE CURRENT
PATTERN AND INDICATES THE UPPER RIDGE OVERHEAD WEAKENING AS A
SHORTWAVE TROUGH ADVANCES EWD FROM THE PLAINS TO THE MID-ATLANTIC
COAST TONIGHT INTO FRIDAY. THE ASSOCIATED COLD FRONT CURRENTLY
ANALYZED OVER THE SERN STATES WILL APPROACH AND MOVE INTO THE LOCAL
AREA LATER TONIGHT INTO FRIDAY, THEN STALL INTO THE WEEKEND. THIS
BOUNDARY COMBINED WITH PLENTY OF MOISTURE SHOULD BE ENOUGH TO
GENERATE A FEW SHOWERS FRIDAY THROUGH SATURDAY OVER PORTIONS OF THE
LOCAL AREA. ABOVE AVERAGE TEMPERATURES WILL RESULT THROUGH THIS
PERIOD.

LONG TERM (SUNDAY-THURSDAY)...

ABOVE AVERAGE TEMPERATURES WILL LIKELY PERSIST THROUGH THE LATTER
HALF OF THE WEEKEND AND INTO THE UPCOMING WEEK AS THE STALLED
FRONTAL BOUNDARY OVER THE STATE RETURNS NORTHWARD AND UPPER
HEIGHTS BEGIN TO RISE. THE EXTENDED GUIDANCE REMAINS IN DECENT
AGREEMENT THROUGH WEDNESDAY AND GENERALLY INDICATES A FAIRLY DRY
PATTERN ACROSS THE FL PENINSULA AS THE UPPER RIDGE BUILDS OVERHEAD.
LOW-LEVEL FLOW IS PROGGED TO REMAIN OUT OF THE EAST EARLY NEXT
WEEK SOUTH OF A RIDGE AXIS WITH TEMPS REMAINING 5-10 DEG ABOVE
AVERAGE. FORECAST CONFIDENCE DECREASES BEYOND WEDNESDAY DUE TO
INCREASING MODEL DIFFERENCES.


MARINE...

A COLD FRONT WILL APPROACH LATER TODAY AND MOVE INTO THE MARINE
AREAS TONIGHT. THIS BOUNDARY IS FORECAST TO STALL ACROSS THE REGION
OVER THE WEEKEND AND KEEP THE RAIN CHANCES IN THE FORECAST.
INCREASING WINDS AND SEAS OUT OF THE NORTH ARE EXPECTED FRIDAY
THROUGH SATURDAY, MAINLY OVER THE NORTHERN PALM BEACH AND GULF
WATERS.
