DISCUSSION
ISSUED AT 400 PM EST MON JAN 20 2025
TONIGHT...THE COLD FRONT DRAPED JUST SOUTH OF THE FLORIDA
PENINSULA IS FORECAST LIFT NORTHWARD BACK TOWARDS THE PENINSULA
TONIGHT, LEADING TO INCREASING RAIN CHANCES FROM THE SOUTH TOWARDS
THE NORTH AFTER MIDNIGHT AND INTO EARLY MORNING. LIGHTNING IS NOT
FORECAST WITH THIS ACTIVITY. NORTHERLY WINDS ARE EXPECTED TO
PREVAIL OVERNIGHT, WITH CONSIDERABLE CLOUD COVERAGE PRESENT ACROSS
EAST CENTRAL FLORIDA. COOL ACROSS THE AREA TONIGHT, WITH LOWS IN
THE UPPER 30S TO LOW 40S NORTH OF THE I-4 CORRIDOR, AND IN THE MID
40S TO LOW 50S SOUTHWARDS. SOME AREAS ALONG THE TREASURE COAST,
PARTICULARLY ALONG THE IMMEDIATE COAST, MAY ONLY FALL INTO THE MID
50S TONIGHT.
TUESDAY-WEDNESDAY...THE AFOREMENTIONED FRONTAL BOUNDARY IS
FORECAST TO REMAIN DRAPED ACROSS THE FLORIDA PENINSULA OVER THE
NEXT SEVERAL DAYS, WITH A COUPLE OF LOW PRESSURE WAVES FORECAST TO
RIDE ALONG THE BOUNDARY. AS A RESULT, RAIN CHANCES REMAIN HIGH
(60-90%) OVER THE NEXT FEW DAYS THANKS TO PLENTIFUL MOISTURE
PRESENT ACROSS THE AREA. THE SUNSHINE STATE ALSO WON'T QUITE BE
LIVING UP TO ITS NAME, WITH CONSIDERABLY CLOUDY SKIES FORECAST
THROUGH AT LEAST WEDNESDAY AS A RESULT OF THE INCREASED MOISTURE.
OUTSIDE OF THE RAINY CONDITIONS, WINDS ARE FORECAST TO PICK UP
BEHIND THE FIRST LOW PRESSURE WAVE THAT TRANSITS THE AREA, WITH
THE TIGHTENING PRESSURE GRADIENT LEADING TO NORTHERLY WINDS
INCREASING TO 15 TO 25 MPH AND GUSTS OF 35 TO 40 MPH POSSIBLE. THE
STRONGEST WINDS WILL LIKELY BE FELT ALONG THE COAST. AS A RESULT
OF THE INCREASING WINDS, SEAS ARE FORECAST TO BUILD ACROSS THE
LOCAL ATLANTIC WATERS TUESDAY NIGHT INTO WEDNESDAY. AT THE
BEACHES, CONDITIONS MAY BECOME HAZARDOUS, WITH BREAKING WAVES OF 4
TO 7 FEET POSSIBLE IN THE SURF ZONE. ENTERING THE SURF WILL NOT
BE ADVISED DURING THIS TIME, AND THE ISSUANCE OF A HIGH SURF
ADVISORY WILL LIKELY BE NEEDED. WINDS ARE FORECAST TO SLOWLY
DIMINISH AS THE PRESSURE GRADIENT SLACKENS WEDNESDAY NIGHT, BUT
WILL REMAIN OUT OF THE NORTH.
TEMPERATURES ARE FORECAST TO REMAIN BELOW NORMAL FOR THIS TIME OF
YEAR, WITH HIGHS IN THE 50S ACROSS MUCH OF THE INTERIOR AND ALONG
THE COAST NORTH OF THE CAPE AND IN THE 60S ALONG THE COAST SOUTH
OF THE CAPE. QUITE THE GRADIENT AT NIGHT, WITH LOWS GENERALLY IN
THE MID 30S TO MID 40S NEAR AND NORTH OF THE I-4 CORRIDOR AND IN
THE MID 40S TO MID 50S SOUTH OF THE I-4 CORRIDOR. WIND CHILL
VALUES FALL INTO THE LOW TO MID 30S ACROSS MUCH OF THE INTERIOR
TUESDAY NIGHT INTO WEDNESDAY MORNING, IMPROVING TO THE MID TO
UPPER 30S WEDNESDAY NIGHT INTO THURSDAY MORNING AS WINDS DIMINISH.
THURSDAY-MONDAY (PREVIOUS MODIFIED)...A CONTINUED UNSETTLED WEATHER
PATTERN IS FORECAST LATE WEEK AS ANOTHER WEAK WAVE OF LOW PRESSURE
RIDES ALONG THE NEARBY STALLED FRONT THU WITH SCATTERED SHOWERS
(POPS 40-50%), DEPARTING THU NIGHT. MORE SIGNIFICANT DRYING IS
FORECAST TO OVERSPREAD THE AREA FRI-SAT WITH THE COLDEST TEMPS
FORECAST FOR THIS WEEK. WIDESPREAD 30S IS FORECAST BY SAT MORNING
WITH LOW-MID 40S IMMEDIATE COAST. INCREASING SUNSHINE SHOULD ALLOW
MAX TEMPS TO FINALLY RISE INTO THE 60S ACROSS NORTHERN SECTIONS. AS
HIGH PRESSURE TRACKS EAST INTO THE ATLC OFF THE CAROLINA COAST SUN,
LOCAL WINDS WILL TURN ONSHORE AND ALLOW A WARMING TREND TO TAKE
HOLD. MAX TEMPS SUNDAY IN THE LOW TO MID 70S, INCREASING INTO THE
LOW TO UPPER 70S ON MONDAY.

CHANCES LOCALLY TONIGHT, WITH HIGH RAIN CHANCES PERSISTING OVER
THE NEXT SEVERAL DAYS AS A SERIES OF LOW PRESSURE WAVES MOVE ALONG
