.DISCUSSION...

...BLUSTERY WITH COLD WIND CHILLS OVERNIGHT...

CURRENT/OVERNIGHT...COLD FRONT HAS CLEARED COVERAGE WARNING AREA
THIS EVENING AND IS PUSHING SOUTH OF LAKE OKEECHOBEE. DRIER AND
COOLER CONDITIONS ARE FILTERING SOUTHWARD ACROSS THE NORTH CENTRAL
PENINSULA IN ITS WAKE. LOW OVERCAST IS BEING OBSERVED BEHIND THIS
BOUNDARY FROM KSFB/KMCO SOUTHWARD. NORTH OF KMCO SKIES REMAIN
OVERCAST BUT CEILINGS ARE PRESENTLY MUCH HIGHER. HAVE LOWERED POPS A
GOOD 10%-20% ACROSS THE AREA THIS EVENING WITH 20%-30% STILL AROUND
THE ORLANDO METRO NORTHWARD AND 30%-50% SOUTHWARD THRU THE TREASURE
COAST. CURRENT RADAR TRENDS ARE VERY LIGHT WITH ANYTHING THAT IS
CURRENTLY FALLING TO THE GROUND...THOUGH EXPECT COVERAGE TO INCREASE
A BIT AFTER MIDNIGHT. WILL LIKELY AXE CURRENT FREEZE WATCH FOR OVERNIGHT.
STILL FEEL THAT WE WON'T MAKE CRITERIA TO WARRANT AN UPGRADE TO A
FREEZE WARNING AND IT IS TOO LATE FOR ANY OF OUR CUSTOMERS TO TAKE
ACTION IF IT WERE TO BE UPGRADED ANYWAY. CLOUD COVER AND ELEVATED
WINDS WILL NOT MAKE IT EASY FOR US TO FALL BELOW FREEZING FOR ANY
LENGTHY PERIOD. ALSO AM A LITTLE UNEASY ABOUT WHAT IT IMPLIES
HAVING A FREEZE WARNING OUT WITH POPS AS WELL...EVEN THOUGH ANY
FROZEN PRECIPITATION THAT MAY FALL LATER ON WILL BE VERY LIGHT AND
MOST LIKELY NOT MEASURING OVER MORE THAN JUST A TRACE.
NONETHELESS...WILL HAVE TO REMAIN VIGILANT LATE OVERNIGHT AND EARLY
SAT MORNING FOR THE POTENTIAL OF A POST FRONTAL MIXED PHASE
PRECIPITATION DEVELOPMENT WITH A LIGHT RAIN...SLEET
COMBINATION...POSSIBLY CHANGING TO A RAIN/SNOW/SLEET COMBINATION
ACROSS ORANGE COUNTY AND NORTH BREVARD NORTHWARD. WIND CHILL
ADVISORY STILL LOOKS APPROPRIATE AND ON TRACK FOR THIS EVENING &
OVERNIGHT AND WILL LEAVE AS IS.

SATURDAY...(PREVIOUS)...A RARE DAY FOR THE SUNSHINE STATE WITH A
POSSIBLE EARLY MIXTURE OF ISOLATED LIGHT RAIN/SLEET SNOW EARLY OVER
THE ORANGE/NORTH BREVARD COUNTY AREA AND LIGHT RAIN SPRINKLES IN THE
MORNING TO EARLY AFTERNOON ACROSS THE REMAINDER OF THE AREA.
PRECIPITATION WL COME TO AN END OVER MOST AREAS BY EARLY AFTERNOON
WITH GRADUAL CLEARING AS ARCTIC AIR CONTINUES TO SPILL SOUTH INTO
THE STATE. TEMPERATURES WILL STRUGGLE TO MAKE IT INTO THE 40S OVER
NORTHERN SECTIONS WITH TEMPS HOVERING IN THE LOW TO MID 40S OVER THE
REMAINDER OF THE AREA. WIND CHILL TEMPERATURES WILL REMAIN A CONCERN
ALL DAY AND THE CURRENT ADVISORY REMAINS VALID UNTIL NOON.

.AVIATION...ARCTIC FRONT HAS RECENTLY PASSED THRU THE REGION. HAVE
LEFT OUT MENTION OF FRZN PCPN FROM LATEST TAF ISSUANCE...THOUGH IT
REMAINS A POSSIBILITY TO ADD IN FOR TEMPO GROUPS A LITTLE
LATER...ESP KMCO/KLEE/KSFB/KDAB. NONETHELESS GENERAL AVIATION MAY
ENCOUNTER FRZN PCPN (-SN/IP) NOT VERY FAR OFF THE GROUND LATE
TONIGHT INTO SAT MORNING. MVFR/IFR CONDS ACROSS MUCH OF EAST CENTRAL
FLORIDA INTO OVERNIGHT WITH AREAS -RA BECOMING MORE NUMEROUS AFT
06Z. GRADUAL IMPROVEMENTS AFT 16Z SAT FROM N-S.

.MARINE...OVERNIGHT-SAT...POST FRONTAL WINDS WILL STEADILY INCREASE
OVERNIGHT AS MUCH COOLER AND DRIER AIR SWEEP SOUTHWARD. WILL LEAVE
ALONE CURRENT SCA IN PLACE FOR OFFSHORE WATERS AS WINDS INCREASE AND
SEAS BUILD. CHOPPY CONDITIONS EXPECTED OVER THE NEARSHORE WATERS ON
SATURDAY WITH CAUTIONARY STATEMENTS LIKELY IN PLACE.

.FIRE WEATHER...(PREVIOUS)...NO HEADLINES ANTICIPATED SATURDAY DUE
TO CLOUD COVER AS WELL AS COOL TEMPERATURES. MIN RHS IN THE 32-35
