AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
347 PM EST SUN DEC 28 2014

.SHORT TERM (TONIGHT-TUESDAY NIGHT)...

WITH LESS CLOUDS TODAY, DEWPOINT DEPRESSIONS AT THIS HOUR ARE A
LITTLE LARGER THAN YESTERDAY AT THIS SAME TIME. ALTHOUGH HIGH
PRESSURE HAS SHIFTED TO THE EAST SLIGHTLY, STILL EXPECTING FOG TO
DEVELOP ACROSS THE INTERIOR AND GULF COAST/LAKE REGION. DENSE FOG
MAY ONCE AGAIN BE PREVALENT THROUGH COLLIER/GLADES/HENDRY COUNTIES.
ON THE EAST COAST, LOWER VISIBILITIES WILL BE PATCHY AND WELL
WEST OF THE CITIES, AND PERHAPS EVEN LESS THAN WHAT WAS
EXPERIENCED THIS MORNING. WEAK DISTURBANCE AHEAD OF A SUBTLE FRONT
MOVING INTO THE PANHANDLE TOMORROW, MAY BE RESPONSIBLE FOR AN
ISOLATED SHOWER ACROSS THE NORTHWESTERN THIRD OF THE CWA IN THE
AFTERNOON. SREF PROBS ARE BULLISH REGARDING SEA FOG DEVELOPMENT IN
THE GULF WATERS BEGINNING MONDAY. SOME OF THIS MAY SNEAK INTO
COLLIER COUNTY OR NAPLES MONDAY EVENING. BY TUESDAY, THE WEAK
FRONTAL BOUNDARY, ALONG WITH AN UPPER LEVEL DISTURBANCE WILL
SETTLE NEAR CENTRAL FLORIDA AS IT ERODES, WITH SOME SHOWERS INTO
THE LAKE REGION AND MORE CLOUDS ACROSS SOUTH FLORIDA.

.LONG TERM (WEDNESDAY-SUNDAY)...

BY WEDNESDAY, A CLOSED UPPER LOW DROPS INTO THE SW CONUS, AND AN
OMEGA BLOCK SITS IN THE PACIFIC. AS THIS POTENT UPPER SYSTEM MOVES
INTO THE FOUR CORNERS REGION BY THE NEW YEAR, THE UPPER RIDGE
WILL STRENGTHEN OVER THE BAHAMAS. WITH SURFACE HIGH PRESSURE
ACROSS THE EASTERN CONUS, MOIST EASTERLY FLOW WILL PERSIST ACROSS
SOUTH FLORIDA. WITH INCREASING ALONG THE STALLED FRONTAL
BOUNDARY, SHOWERS MAY MAKE BETTER PROGRESSION INTO THE CITIES
WEDNESDAY AND WEDNESDAY NIGHT. THE REST OF THE WEEK SHOULD BE
HUMID WITH SOME COASTAL SHOWERS AS SURFACE HIGH PRESSURE REMAINS
IN THE WESTERN ATLANTIC, AND THE AFOREMENTIONED UPPER LOW IS KEPT
WELL AWAY FROM SOUTH FLORIDA THANKS TO THE PARKED UPPER RIDGE
ACROSS THE CARIBBEAN.

&&

.MARINE...

HIGH RISK OF RIP CURRENTS FOR PALM BEACH COUNTY WILL BE ALLOWED
TO EXPIRE AT 7PM.

HIGH PRESSURE DEPARTS AS A WEAK FRONT ENTERS FLORIDA MONDAY AND
TUESDAY. SHOWERS ALONG WITH SEA FOG MAY DEVELOP THROUGH THE GULF
WATERS TOMORROW AND TOMORROW NIGHT. WINDS WILL VEER BRIEFLY TO THE
SOUTH AHEAD OF THIS FRONT, THEN BACK TO THE NE AND E, THROUGH THE
REST OF THE WEEK, AS THE FRONT STALLS THROUGH THE FLORIDA STRAITS .

&&

.PREV DISCUSSION... /ISSUED 1232 PM EST SUN DEC 28 2014/

AVIATION...
HIGH PRESSURE WILL CONTINUE TO KEEP THE WEATHER QUIET THROUGH
THE TAF PERIOD. GENERALLY VFR CONDITIONS ARE EXPECTED AT THE
MAJORITY OF THE TAF SITES. EXCEPTIONS MAY BE KAPF AND KTMB, WHERE
FOG COULD IMPAIR VIS ONCE AGAIN TONIGHT. HAVE JUST A MENTION OF
FOG FOR NOW, WITH 3SM AS THE PREVAILING VIS. HOWEVER, IFR
CONDITIONS WILL BE POSSIBLE. CURRENTLY NOT EXPECTING ANY OF THE
OTHER SITES TO SEE ANY IMPACTS FROM ANY FOG THAT IS ABLE TO FORM.
