AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
1015 AM EST SAT JAN 18 2014

.DISCUSSION...

COLD AIR ADVECTION BEHIND COLD FRONTAL PASSAGE THIS MORNING IS
PRODUCING GUSTY NW WINDS WITH TEMPERATURES IN THE 40S AND 50S. THE
GUSTY WINDS WILL SUBSIDE THIS AFTERNOON AS HIGH PRESSURE MOVES EAST
ACROSS THE GULF OF MEXICO AND PRESSURE GRADIENT WEAKENS. HIGHS WILL
NOT GET OUT OF THE 50S NORTH OF ORLANDO/CAPE DESPITE FULL
SUNSHINE...BUT SHOULD REACH THE MID 60S MARTIN COUNTY.

TONIGHT...TEMPERATURES WILL FALL QUICKLY WITH SUNSET AS WINDS
DIMINISH UNDER CLEAR SKIES AND VERY DRY AIRMASS. THE HIGH PRESSURE
RIDGE WILL CONTINUE TO PRESS SOUTH INTO SOUTH CENTRAL FL. THIS WILL
INCREASE WESTERLY FLOW OVERNIGHT ACROSS NORTH AND CENTRAL FL WHICH
SHOULD LIMIT EXTENT OF FROST/FREEZE CONDITIONS. AS A RESULT...
COLDEST TEMPS ARE ACTUALLY FORECAST TO BE ACROSS OKEECHOBEE/TREASURE
COAST DUE TO VERY LIGHT/CALM WINDS IN VICINITY OF RIDGE AXIS. THIS
IS THE REASON FOR THE FREEZE WATCH AND WILL DECIDE ON WHETHER TO
UPGRADE TO A FREEZE WARNING OR SWITCH TO A FROST ADVISORY AFTER
EVALUATING THE 12Z MODEL SUITE OF GUIDANCE PRODUCTS. WILL LIKELY
HOLD ONTO PATCHY FROST EVEN ACROSS NORTHERN SECTIONS (ORLANDO NORTH)
ESP FOR WIND PROTECTED AREAS.

&&

.AVIATION...
VFR. GUSTY NW WINDS BEHIND FRONT THIS MORNING WILL SUBSIDE A BIT
THIS AFTERNOON. FLOW WILL BACK TO THE WEST AND BECOME LIGHT AFTER
00Z.

&&

.MARINE...
COLD FRONT HAS NOW PUSHED SOUTH OF JUPITER INLET WITH NW WINDS
AROUND 20 KNOTS WITH SOME HIGHER GUSTS ACROSS THE ATLC COASTAL
WATERS. BECAUSE OF THE OFFSHORE FLOW...SEAS ARE SUPPRESSED NEARSHORE
AT 3-4FT BUT BUILD TO 8 FEET WELL OFFSHORE. WILL MAINTAIN THE
ADVISORY FOR WINDS NEARSHORE BUT SHOULD SEE GRADUALLY IMPROVING
CONDITIONS NEAR THE COAST THRU THE DAY AND WILL CERTAINLY BE ABLE TO
LET THE ADVISORY (FOR WINDS) EXPIRE BY 4 PM. THE ADVISORY FOR WINDS
AND SEAS OFFSHORE WILL CONTINUE TIL 7 PM.

&&

.FIRE WEATHER...
GUSTY NW WINDS BEHIND COLD FRONT THIS MORNING WILL SUBSIDE A BIT
THIS AFTERNOON. DESPITE VERY COOL TEMPS IN THE MID/UPPER 50S THIS
AFTERNOON...MIN RH VALUES ARE STILL FORECAST TO DIP INTO THE TEENS
ACROSS THE NORTHERN SECTIONS WHICH IS A TESTAMENT TO THE VERY DRY
AIRMASS. BECAUSE OF THE WIND...TODAY IS A MORE FIRE SENSITIVE DAY
THAN YESTERDAY WITH POTENTIAL FOR ANY NEW OR ONGOING FIRES TO SPREAD
RAPIDLY.
