PREVIOUS DISCUSSION
ISSUED AT 500 AM EST SUN JAN 19 2025
TODAY...VERY MILD START TO THE DAY AS AREA IS SQUARELY WITHIN THE
WARM SECTOR WITH PATCHY STRATUS AND FOG LIFTING NORTHWARD. A COLD
FRONT IS ON TRACK TO CROSS THE AREA DURING THE DAY, AND BRING A
BAND OF SHOWERS AND EMBEDDED STORMS ACROSS THE AREA AS EARLY AS
THIS MORNING ACROSS THE FAR NORTH, REACHING THE TREASURE COAST
LATE THIS AFTERNOON. WIND FIELDS ARE QUITE STRONG JUST ABOVE THE
BOUNDARY LAYER. AS THE LOW CLOUDS BREAK UP ACROSS THE SOUTH HALF
OF FA AND SOME HEATING/MIXING CAN DEVELOP, THERE IS A REASONABLE
CHANCE FOR WINDS TO GUST 35-40 MPH SOUTH OF ORLANDO SO A WIND
ADVISORY HAS BEEN ISSUED. THESE WIND FIELDS WILL ALSO OFFER AN
OPPORTUNITY FOR STRONG, POSSIBLY DAMAGING WINDS IN STORMS THAT CAN
HARNESS THE CORRIDOR OF DESTABILIZATION THAT COULD OCCUR WITHIN
AN ENVIRONMENT OF DEEP LAYER SHEAR. IF THIS HAPPENS, A TORNADO
CANNOT BE RULED OUT. MAX TEMPS WILL RANGE FROM THE LOWER 70S
ACROSS LAKE/VOLUSIA WHERE CLOUDS AND EARLY RAIN/STORMS WILL BE
FOLLOWED QUICKLY BY THE FRONT. NOTICEABLY WARMER ACROSS SOUTHERN
SECTIONS IN THE LOWER 80S PRIOR TO FRONTAL PASSAGE.
MON-WED...THE FRONT IS FORECAST TO STALL ACROSS THE FL STRAITS
MON WITH MOSTLY DRY WEATHER ACROSS EC FL WITH THE EXCEPTION OF
ISOLATED SHOWERS (POPS ~20%) FORECAST OVER THE TREASURE COAST.
RAIN CHANCES INCREASE NORTHWARD BY TUE AS A COASTAL TROUGH MOVES
NORTH OVER THE WESTERN ATLANTIC ALONG THE COAST OF EAST CENTRAL
FLORIDA INTO TUESDAY AFTERNOON. SCATTERED TO NUMEROUS SHOWERS
(POPS ~50-70%) ARE FORECAST TO DEVELOP FROM SOUTH TO NORTH OVER
EAST CENTRAL FLORIDA LATE MON NIGHT AND CONTINUE MOST IF NOT ALL
DAY TUESDAY. IT IS UNUSUAL TO GET AN ALL-DAY RAIN HERE IN CENTRAL
FL (OUTSIDE OF TROPICAL SYSTEMS) BUT CONDITIONS LOOK FAVORABLE FOR
THIS INCLUDING A STALLED FRONTAL BOUNDARY, OVERRUNNING AND UPPER
SUPPORT. THE MAIN HAZARDS TUE WILL BE GUSTY WINDS AND MODERATE TO
LOCALLY HEAVY RAINFALL. MAX TEMPS MON WILL BE MUCH BELOW NORMAL
ONLY REACHING THE LOWER TO MID 50S ACROSS THE NORTH TO THE MID 60S
TREASURE COAST. UPPER 50S LAKE COUNTY TO LOW 70S TREASURE COAST
FORECAST ON TUESDAY. COLD TEMPERATURES ARE EXPECTED MONDAY AND
TUESDAY MORNINGS WITH LOWS GENERALLY IN THE UPPER 30S FAR NORTH TO
MID 50S TREASURE COAST. AND WIND CHILL VALUES IN THE LOW-MID 30S
ALONG AND NORTH OF I 4.
THE MID-LEVEL DISTURBANCE RESPONSIBLE FOR THIS ACTIVE WEATHER IS
PREDICTED TO MOVE BY ON TUESDAY NIGHT. THIS SHOULD FORCE THE FRONT
SOUTHWARD WHILE CONTINUING THE HIGH RAIN COVERAGE. THE POTENTIAL
FOR WINDY CONDITIONS IS INCREASING ALONG AND JUST BEHIND THE
FRONT. STATISTICAL GUIDANCE SUPPORTS A 60-70% CHANCE OF PEAK GUSTS
EXCEEDING 35 MPH ALONG THE COAST. THIS WILL LIKELY LEAD TO
HAZARDOUS SURF CONDITIONS TUESDAY NIGHT INTO WEDNESDAY.
BEHIND THE BOUNDARY, COLDER AIR IS DRAWN SOUTHWARD AGAIN, AND
SUNRISE WEDNESDAY TEMPERATURES ARE NOW FORECAST IN THE UPPER 30S
NORTHWEST OF ORLANDO. TEMPERATURES STILL LOOK TOO WARM FOR ANY
WINTER WEATHER IMPACTS OVER OUR FORECAST AREA. RAIN SHOWERS ARE
EXPECTED TO EXIT DURING THE DAY ON WEDNESDAY.
THU-SAT...A CONTINUED UNSETTLED WEATHER PATTERN IS FORECAST MID
TO LATE WEEK AS ANOTHER WEAK WAVE OF LOW PRESSURE RIDES ALONG THE
NEARBY STALLED FRONT. SHOWERS ARE LIKELY TO INCREASE AGAIN ON THU
(POPS 50-60%). DEPENDING ON WHERE THE SHARPENING FRONT/BAROCLINIC
ZONE SETS UP WILL DETERMINE THE HEAVIEST AXIS OF RAIN. WINDS TURN
ONSHORE WHICH WILL RESULT IN MILDER TEMPERATURES ESP SOUTHEAST OF
I-4 WITH LOW TO MID 70S TREASURE COAST. FINALLY, SIGNIFICANT
DRYING IS FORECAST TO OVERSPREAD THE AREA FRI-SAT BUT COLD HIGH
PRESSURE WILL KEEP TEMPS BELOW NORMAL WITH MAX TEMPS HOLDING IN
THE 50S NORTH OF I 4 AND LOWS SAT MORNING IN THE 30S ACROSS ALL
THE INTERIOR, INCLUDING COASTAL VOLUSIA WITH LOW TO MID 40S
ELSEWHERE.
MARINE
ISSUED AT 500 AM EST SUN JAN 19 2025
TODAY...SMALL CRAFT ADVISORIES (SCA) ARE IN EFFECT FOR THE
OFFSHORE WATERS FOR SOUTHWEST WINDS 20-25 KNOTS. THEN WINDS WILL
VEER NW TO N BEHIND A COLD FRONT THIS EVENING AND BRING ADVISORY
CONDITIONS (NEAR 20 KNOTS) TO THE NEARSHORE VOLUSIA AND BREVARD
WATERS. SEAS WILL BE CHOPPY TODAY BUT REMAIN 2 FEET NEAR THE COAST
DUE TO THE OFFSHORE FLOW. CONDITIONS WILL DETERIORATE TONIGHT AS
NORTH WINDS INCREASE AND SEAS BUILD 3-5 FT NEARSHORE AND UP TO 8
FEET IN THE GULF STREAM.
MON-THU...POOR TO HAZARDOUS BOATING CONDITIONS WILL PERSIST MON
DUE TO THE NORTH WINDS AND SEAS REMAINING 7 FEET IN THE GULF
STREAM. A COASTAL TROUGH IS EXPECTED TO DEVELOP ON TUESDAY AND
MOVE NORTH OVER THE WESTERN ATLANTIC ALONG THE EASTERN CENTRAL
FLORIDA COAST. STRONG TO NEAR GALE FORCE NORTHERLY WINDS ARE
FORECAST AS LOW PRESSURE DEVELOPS OVER THE EAST CENTRAL FLORIDA
ATLANTIC WATERS INTO WEDNESDAY. THE CHANCE FOR GUSTS TO GALE FORCE
CONTINUES TO INCREASE. THE BOTTOM LINE IS THAT MARINERS SHOULD
MONITOR THE FORECAST AS A PERIOD OF DANGEROUS WINDS AND SEAS ARE
FORECAST FROM LATE TUESDAY INTO WEDNESDAY. DESPITE DRIER AIR
MOVING INTO THE AREA LATE WEEK, WINDS AND SEAS ARE FORECAST TO
REMAIN HAZARDOUS FOR BOATING INTERESTS.
