DISCUSSION
ISSUED AT 400 PM EST TUE JAN 21 2025
TONIGHT...A BRIEF LULL IN SHOWERS THIS AFTERNOON WILL BE SHORT
LIVED, WITH SHORT RANGE GUIDANCE HINTING AT INCREASING COVERAGE
ONCE AGAIN OVERNIGHT. THE FRONTAL BOUNDARY IS DRAPED ACROSS SOUTH
FLORIDA THIS AFTERNOON, WITH A PLUME OF MOISTURE NORTH OF THE
BOUNDARY KEEPING CENTRAL FLORIDA UNDER CLOUDY SKIES AND SHOWERS
INTO THE OVERNIGHT PERIOD. LIGHTNING ACTIVITY IS STILL NOT
FORECAST WITH THESE SHOWERS.
A SURGE OF NORTHERLY WINDS MOVING FROM THE NORTH TOWARDS THE
SOUTH ACROSS EAST CENTRAL FLORIDA WILL LEAD TO WINDS INCREASING TO
10 TO 20 MPH, WITH GUSTS TO 30 TO 40 MPH POSSIBLE. A WIND
ADVISORY GOES INTO EFFECT AT 5 PM ALONG THE VOLUSIA AND BREVARD
COASTS, AND EXPANDS TO SOUTHERN BREVARD AND THE TREASURE COAST AT
MIDNIGHT. THESE INCREASING WINDS WILL CAUSE AN INCREASE IN SEAS AS
WELL, WITH HIGH, POUNDING SURF EXPECTED TO DEVELOP PARTICULARLY
NORTH OF THE CAPE. A HIGH SURF ADVISORY WAS ISSUED FROM 7 PM
TONIGHT TO 7 AM WEDNESDAY FOR BREAKING WAVES OF 8 TO 10 FEET FOR
THE VOLUSIA AND NORTHERN BREVARD COASTS. IT IS ALSO WORTH NOTING
THAT HIGH TIDE OCCURS AT 1:30 AM, WHICH WILL FURTHER ENHANCE THE
POTENTIAL FOR SOME BEACH AND EVEN DUNE EROSION. SOUTHWARD,
BREAKING WAVES OF 4 TO 6 FEET OVERNIGHT WILL BE POSSIBLE, THOUGH
IT WILL BE SHORT LIVED AND CONFIDENCE IN EROSION IS NOT AS HIGH.
IN ADDITION TO THE RAIN AND WIND CONCERNS, COLD TEMPERATURES ARE
FORECAST OVERNIGHT, WITH LOWS GENERALLY IN THE MID TO UPPER 30S
NEAR AND NORTH OF THE I-4 CORRIDOR, AND IN THE 40S SOUTHWARD. SOME
SPOTS ALONG THE TREASURE COAST ARE FORECAST TO FALL INTO THE LOW
50S. WIND CHILL VALUES NORTH OF THE I-4 CORRIDOR ARE FORECAST TO
FALL INTO THE MID 20S TO LOW 30S, AND AS A RESULT, A COLD WEATHER
ADVISORY HAS BEEN ISSUED FROM 1 AM TO 9 AM FOR LAKE, VOLUSIA,
SEMINOLE, AND ORANGE COUNTIES.
WEDNESDAY-THURSDAY...THE UNSETTLED WEATHER PATTERN IS FORECAST TO
PERSIST OVER THE NEXT COUPLE OF DAYS AS THE FRONTAL BOUNDARY
REMAINS DRAPED ACROSS SOUTH FLORIDA. A PLUME OF MOISTURE NORTH OF
THE BOUNDARY AND DRAPED ACROSS CENTRAL FLORIDA WILL CAUSE PERSISTENT
SHOWER ACTIVITY WEDNESDAY AND THURSDAY, WITH RAIN CHANCES
REMAINING BETWEEN 40 TO 70 PERCENT. CLOUD COVERAGE ALSO REMAINS
HIGH AS A RESULT OF THE MOISTURE, SO IT MAY BE A FEW DAYS UNTIL
THE SUNSHINE STATE ACTUALLY SEES SOME SUNSHINE. LIGHTNING ACTIVITY
IS NOT EXPECTED WITH THESE SHOWERS. MODEL GUIDANCE IS HINTING AT
SOME DIMINISHING RAIN CHANCES WEDNESDAY NIGHT, BUT KEPT A 20 TO 30
PERCENT CHANCE IN ACROSS THE AREA FOR NOW. ANOTHER WEAK WAVE OF
LOW PRESSURE IS FORECAST TO RIDE ALONG THE BOUNDARY THURSDAY,
EVENTUALLY DRAGGING THE FRONT AWAY FROM THE AREA THURSDAY NIGHT
INTO EARLY FRIDAY. RAIN CHANCES DIMINISH THURSDAY NIGHT ACROSS THE
PENINSULA AS AN AREA OF HIGH PRESSURE BEGINS TO SLOWLY BUILD IN
ACROSS THE PENINSULA, WITH SOME LINGERING ACTIVITY POSSIBLE ACROSS
THE LOCAL ATLANTIC WATERS.
COOLER TEMPERATURES ARE FORECAST TO PERSIST ACROSS THE AREA OVER
THE NEXT COUPLE OF DAYS, WITH AFTERNOON HIGHS GENERALLY IN THE 50S
AND SOME LOW 60S POSSIBLE ALONG THE TREASURE COAST. WEDNESDAY
NIGHT, LOWS IN THE 40S ACROSS MUCH OF THE INTERIOR AND IN THE 50S
ALONG THE COAST SOUTH OF THE CAPE AND ACROSS THE TREASURE COAST.
COOLER ON THURSDAY NIGHT, WITH LOWS IN THE 30S ACROSS MUCH OF THE
INTERIOR AND IN THE LOW TO MID 40S ALONG THE COAST SOUTH OF THE
CAPE AND NEAR LAKE OKEECHOBEE. WIND CHILLS IN THE UPPER 20S TO MID
30S THURSDAY NIGHT.
FRIDAY-TUESDAY (PREVIOUS MODIFIED)...SIGNIFICANT DRYING IS FORECAST
TO OVERSPREAD THE AREA FRIDAY THROUGH SATURDAY WITH THE COLDEST
TEMPS FORECAST FOR THIS WEEK. WIDESPREAD 30S IS FORECAST BY SATURDAY
MORNING WITH LOW TO MID 40S LIMITED TO THE IMMEDIATE TREASURE COAST.
DESPITE INCREASING SUNSHINE, MAXIMUM TEMPERATURES MAY STILL HOLD IN
THE UPPER 50S ACROSS LAKE AND VOLUSIA COUNTIES WITH LOW TO MID 60S
ELSEWHERE. BUT A WARMING TREND APPEARS IN THE CARDS AS HIGH PRESSURE
TRACKS EAST INTO THE ATLANTIC OFF THE CAROLINA COAST SUNDAY, VEERING
THE LOCAL WINDS ONSHORE AND FINALLY LOSING THE NORTH WIND COMPONENT.
DRY CONDITIONS ARE FORECAST TO PREVAIL THROUGH THE REMAINDER OF THE
WEEKEND AND INTO EARLY NEXT WEEK. LOWS SUNDAY MORNING IN THE 40S AND
50S, RISING TO THE LOW TO MID 70S, AND A COUPLE/FEW DEGREES WARMER
ON MONDAY AND TUESDAY.
