DISCUSSION
ISSUED AT 320 PM EST FRI FEB 27 2026
CURRENT-SATURDAY...PREVAILING SOUTHWESTERLY FLOW HAS RESULTED IN
ADVECTION OF WARM, MOIST AIR ACROSS EAST CENTRAL FLORIDA THIS
AFTERNOON, WITH SOME MID AND UPPER LEVEL ENERGY SUPPORTING THE
DEVELOPMENT OF SHOWERS ACROSS THE GULF. THESE SHOWERS ARE
CURRENTLY MOVING EASTWARD ACROSS THE FLORIDA PENINSULA AND HAVE
BEGAN CREEPING INTO LAKE COUNTY, WITH COVERAGE OF SHOWERS
ANTICIPATED TO INCREASE THROUGH THE REMAINDER OF THIS AFTERNOON
AND INTO THE EVENING HOURS AS THE EAST COAST SEA BREEZE DEVELOPS
AND MOVES INLAND, INTERACTING WITH THE EASTWARD-MOVING ACTIVITY.
RAIN CHANCES ARE FORECAST TO REMAIN HIGH (60-80%) INTO THE
OVERNIGHT HOURS AND SATURDAY AS A COLD FRONT DRAPED ACROSS THE
SOUTHEASTERN US MOVES CLOSER TOWARDS THE PENINSULA. SHOWER
DEVELOPMENT WILL THEN PRIMARILY BE FRONTAL-DRIVEN INTO SATURDAY,
THOUGH THE EAST COAST SEA BREEZE WILL ALSO ACT TO ENHANCE ACTIVITY
TOMORROW AFTERNOON. WHILE THE RAIN IS MORE THAN WELCOME ACROSS
THE DROUGHT-STRICKEN FLORIDA PENINSULA, WIDESPREAD RAINFALL TOTALS
OF 0.5-1" WILL NOT HELP MUCH WITH DROUGHT CONCERNS. LOCALIZED
HIGHER AMOUNTS EXCEEDING 1" CANNOT BE RULED OUT IN SOME LOCATIONS.
IN ADDITION TO INCREASING SHOWER COVERAGE, THERE IS ALSO SUPPORT
FOR ISOLATED TO SCATTERED STORMS THIS EVENING AND AGAIN ON
SATURDAY.
MODEST INSTABILITY ACROSS EAST CENTRAL FLORIDA (MUCAPE 500-1000
J/KG) COMBINED WITH MODEST LOW-LEVEL LAPSE RATES AND 500 MB
TEMPERATURES RANGING FROM -12 TO -11C WILL SUPPORT THE DEVELOPMENT
OF ISOLATED TO SCATTERED STORMS THIS AFTERNOON, ESPECIALLY GIVEN
A WEAK WAVE OF ENERGY IN THE MID-LEVELS AND THE INTRUSION INLAND
OF THE EAST COAST SEA BREEZE. WITH THE MODEST INSTABILITY AND
VARIOUS LIFTING MECHANISMS PRESENT, LIGHTNING WILL BE POSSIBLE
WITH ACTIVITY, AND THERE HAVE ALREADY BEEN A COUPLE OF STRIKES
ACROSS EAST CENTRAL FLORIDA THIS AFTERNOON. DRIER AIR IN THE MID-
LEVELS HAS LED TO AN UPTICK IN DCAPE VALUES (700-1000 J/KG) THIS
AFTERNOON, WHICH MEANS GUSTS TO 50 MPH WILL BE POSSIBLE WITH THE
STORMS THAT ARE ABLE TO INTRUDE INTO THE DRY LAYER AND MIX
DOWNWARD. THIS WILL BECOME LESS OF AN ISSUE LATE TONIGHT AS THE
COLUMN CONTINUES TO MOISTEN OVERNIGHT AND DCAPE DECREASES. IN
ADDITION TO THE WINDS, THE COLD TEMPERATURES ALOFT SUPPORT A LOW
CHANCE FOR SOME SMALL HAIL WITH THE STRONGEST STORMS. BOUNDARY
INTERACTIONS BETWEEN OUTFLOW BOUNDARIES AND THE EAST COAST SEA
BREEZE COULD ALSO LEAD TO BRIEF SPIN-UP OR TWO, THOUGH CONFIDENCE
IN THIS REMAINS LOW.
BY SATURDAY, THE APPROACHING FRONTAL BOUNDARY WILL PROVIDE THE
MAIN SOURCE OF FORCING FOR STORM DEVELOPMENT, WITH ADDITIONAL
SUPPORT COMING FROM THE EAST COAST SEA BREEZE IN THE AFTERNOON,
ESPECIALLY ACROSS THE SOUTHERN PORTIONS OF EAST CENTRAL FLORIDA.
MUCAPE VALUES JUMP TO 1000-1500 J/KG ACROSS MOST OF EAST CENTRAL
FLORIDA TOMORROW AND MODESTLY STEEP LOW-LEVEL LAPSE RATES WILL
SUPPORT THE POTENTIAL FOR DEEPER CONVECTION. DCAPE VALUES REMAIN
AROUND 600-800 J/KG, AND THERE IS ALSO A NOTED INCREASE IN THE
MID-LEVEL WINDS WITH THE CLOSER ARRIVAL OF THE MID-LEVEL TROUGH
OVERHEAD. THIS WILL SUPPORT THE POTENTIAL FOR STRONGER WIND GUSTS
WITH STORM ACTIVITY. 500 MB TEMPERATURES CONTINUE TO COOL, WITH
MODELED SOUNDINGS INDICATING VALUES FALLING TO -14 TO -13C. ALL OF
THESE FACTORS COMBINED WITH GUIDANCE HINTING AT A DECENT CHANCE
FOR FRONTAL AND EAST COAST SEA BREEZE INTERACTIONS HAS PROMPTED
SPC TO HIGHLIGHT AREAS SOUTHWARD OF KISSIMMEE AND CAPE CANAVERAL
IN A MARGINAL RISK (1/5) FOR SEVERE STORM DEVELOPMENT. THE PRIMARY
HAZARDS WITH STORM DEVELOPMENT TOMORROW WILL INCLUDE FREQUENT
LIGHTNING STRIKES, DAMAGING WIND GUSTS UP TO 60 MPH, AND A LOW
CHANCE FOR HAIL UP TO 1 INCH IN DIAMETER. BOUNDARY INTERACTIONS
WILL ALSO NEED TO BE MONITORED FOR BRIEF, WEAK SPIN UPS,
ESPECIALLY DOWN SOUTH WHERE INTERACTIONS WITH THE SEA BREEZE
OCCUR. ACTIVITY WILL GENERALLY MOVE OFFSHORE INTO THE OVERNIGHT
HOURS ON SATURDAY, DIMINISHING FROM NORTH TO SOUTH AS THE FRONT
SLOWLY SHIFTS SOUTHWARD SATURDAY NIGHT.
AFTERNOON TEMPERATURES TODAY CONTINUE TO REMAIN ON TRACK TO REACH
THE 80S AREAWIDE, FALLING INTO THE 60S TONIGHT. SATURDAY, THE
TEMPERATURE GRADIENT TIGHTENS WITH THE APPROACH OF THE FRONT FROM
NORTH TO SOUTH, WITH HIGHS RANGING FROM THE LOW 70S ACROSS VOLUSIA
AND NORTHERN LAKE TO THE LOW 80S ACROSS THE TREASURE COAST AND
NEAR LAKE OKEECHOBEE. LOWS SATURDAY NIGHT WILL BE CLOSER TO NORMAL
BEHIND THE FRONT, FALLING INTO THE 50S NEARLY AREAWIDE.
SUNDAY-FRIDAY...SUNDAY ACTS AS A TRANSITION PERIOD FOR THE MID-
LEVELS, AS A BROAD TROUGH SHIFTS OFFSHORE AND ALLOWS FOR A GRADUAL
BUILD OF RIDGING THROUGH NEXT WEEK. AT THE SURFACE, NORTHEAST
WINDS ON SUNDAY BECOME MORE ONSHORE INTO MONDAY AS AN AREA OF
SURFACE HIGH PRESSURE STRENGTHENS TO THE NORTH, WITH WINDS
REMAINING ONSHORE THROUGH MOST OF THE UPCOMING WEEK. THIS ONSHORE
FLOW IN COMBINATION WITH A WEAK STALLED BOUNDARY TO THE NORTH OF
EAST CENTRAL FLORIDA IS FORECAST TO FAVOR THE DEVELOPMENT OF SOME
ISOLATED TO SCATTERED SHOWER ACTIVITY ACROSS THE LOCAL ATLANTIC
WATERS, WITH A LOW CHANCE (20-30%) FOR SOME ONSHORE-MOVING SHOWERS
EACH AFTERNOON FROM MONDAY ONWARD. AT THIS TIME, THERE IS LOW
CONFIDENCE IN ANY STORM ACTIVITY WITH THESE SHOWERS, BUT TRENDS
WILL CONTINUE TO BE CLOSELY MONITORED. TEMPERATURES ACROSS EAST
CENTRAL FLORIDA ARE ANTICIPATED TO GRADUALLY WARM THROUGH THE
EXTENDED PERIOD AS THE HIGH SETS UP TO THE NORTH, KEEPING
AFTERNOON HIGHS AND OVERNIGHT NEAR TO ABOVE NORMAL.
MARINE
ISSUED AT 320 PM EST FRI FEB 27 2026
INCREASING MOISTURE AND THE GRADUAL APPROACH OF A COLD FRONT WILL
LEAD TO INCREASING RAIN AND STORM CHANCES ACROSS THE LOCAL
ATLANTIC WATERS TONIGHT THROUGH SATURDAY. RAIN CHANCES RANGE FROM
60-80% WITH A 20-30% CHANCE FOR STORM DEVELOPMENT. ANY STORMS THAT
MANAGE TO DEVELOP MAY BE CAPABLE OF PRODUCING FREQUENT LIGHTNING
STRIKES, WIND GUSTS IN EXCESS OF 34 KNOTS AND EVEN SMALL HAIL.
ADDITIONALLY, BRIEF SPIN-UPS CANNOT BE ENTIRELY RULED OUT,
ESPECIALLY WHERE STORMS INTERACT WITH THE EAST COAST SEA BREEZE,
THOUGH CONFIDENCE REMAINS LOWER ON THIS. SEAS ARE FORECAST TO
REMAIN BETWEEN 2 TO 4 FEET THROUGH SATURDAY, WITH NORTHERLY WINDS
OF 10 TO 15 KNOTS.
BY SUNDAY, THE FRONT IS ANTICIPATED TO SINK SOUTH OF THE AREA,
RESULTING IN SLIGHTLY DRIER CONDITIONS. HIGH PRESSURE DEVELOPS
JUST TO THE NORTH OF THE LOCAL WATERS, WITH ONSHORE WINDS
DEVELOPING ON MONDAY AND PERSISTING THROUGH MUCH OF NEXT WEEK.
LIGHT, ISOLATED ONSHORE-MOVING SHOWERS CANNOT BE RULED OUT ACROSS
THE WATERS, AND A 20-40% CHANCE OF RAIN IS FORECAST THROUGH MUCH
OF THE EXTENDED FORECAST. WIND SPEEDS INCREASE TO 15 TO 25 KNOTS
LATE MONDAY THROUGH AT LEAST WEDNESDAY AND SEAS RESPOND BY
BUILDING TO 5 TO 9 FEET, CONTINUING THROUGH LATE NEXT WEEK. SMALL
CRAFT ADVISORIES WILL LIKELY BE NEEDED ACROSS ALL LEGS OF THE
LOCAL ATLANTIC WATERS DUE TO THE POOR TO HAZARDOUS BOATING
CONDITIONS.
AVIATION
(00Z TAFS)
ISSUED AT 730 PM EST FRI FEB 27 2026
SCATTERED SHRA/TSRA WILL CONTINUE TO MOVE EAST FROM THE GULF AND
WILL IMPACT THE NORTHERN TERMINALS INCL MCO THROUGH 05Z. ADDL TSRA
WILL PUSH OFFSHORE THE TREASURE COAST (VRB-SUA) THROUGH 04Z.
LINGERING SHRA WILL PERSIST OVERNIGHT AND INTO SAT MORNING. A
COLD FRONT WILL SETTLE SOUTHWARD INTO CENTRAL FL EARLY SAT AND
BECOME NEARLY STATIONARY. WIDESPREAD IFR/LIFR CIGS WILL DEVELOP
AFT 05Z ACROSS NORTHERN TERMINALS INCL MCO AND PERSIST THROUGH AT
LEAST 15Z. WHILE MCO IS FORECAST TO SHOW IMPROVEMENT TO VFR CIGS
BY 18Z, SFB AND DAB ARE FORECAST TO REMAIN IN MVFR THROUGH THE
DAY. ANOTHER ROUND OF TSRA IS FORECAST SAT AFTN PRIMARILY SOUTH OF
MCO WHERE MODERATE INSTABILITY AND SEA BREEZE CONVERGENCE CAN
PRODUCE A FEW STRONG TO MARGINALLY SEVERE STORMS.
FIRE WEATHER
ISSUED AT 320 PM EST FRI FEB 27 2026
DESPITE INCREASING MOISTURE, SENSITIVE FIRE WEATHER CONDITIONS
PERSIST ACROSS EAST CENTRAL FLORIDA TODAY INTO SATURDAY. SCATTERED
TO NUMEROUS SHOWERS ARE FORECAST ACROSS THE AREA THIS AFTERNOON
THROUGH SATURDAY AS THE RESULT OF AN APPROACHING COLD FRONT. IN
ADDITION TO SHOWERS, THERE IS A LOW CHANCE (20-30%) OF STORM
DEVELOPMENT ACROSS EAST CENTRAL FLORIDA THIS AFTERNOON THROUGH
SATURDAY. ANY STORMS THAT MANAGE TO DEVELOP MAY BE CAPABLE OF
PRODUCING FREQUENT CLOUD-TO-GROUND LIGHTNING STRIKES, WHICH COULD
RESULT IN NEW FIRES ACROSS EAST CENTRAL FLORIDA. IN ADDITION TO
THE LIGHTNING, WIND GUSTS UP TO 50 MPH CANNOT BE RULED OUT, WHICH
COULD LEAD TO GREATER FIRE SPREAD FOR NEW AND EVEN EXISTING FIRES.
DUE TO THESE FACTORS, THE SIGNIFICANT FIRE POTENTIAL THREAT
REMAINS MODERATE FOR TODAY AND HIGH INTO SATURDAY.
THE FRONT MOVES SOUTH OF THE AREA BY EARLY SUNDAY, WITH MINIMAL
FIRE WEATHER CONCERNS ASIDE FROM THE ONGOING DROUGHT CONDITIONS.
WINDS BECOME MORE ONSHORE BY THE START OF THE WORK WEEK, WITH
ENHANCEMENTS EACH AFTERNOON DUE TO THE EAST COAST SEA BREEZE
CAUSING WIND SPEEDS TO REACH 10 TO 15 MPH. ISOLATED ONSHORE-MOVING
SHOWERS POSSIBLE THROUGH THE EXTENDED FORECAST MOST AFTERNOONS.
MINIMUM RH VALUES REMAIN BELOW CRITICAL THRESHOLDS.
