DISCUSSION
ISSUED AT 256 AM EDT THU OCT 15 2026
TODAY-FRIDAY...BROAD AREA OF HIGH PRESSURE NORTH OF THE AREA WILL
GRADUALLY SHIFT EASTWARD AS A MID/UPPER LEVEL TROUGH MOVING INTO THE
CENTRAL U.S. PUSHES A COLD FRONT INTO THE SOUTHEAST STATES. ONSHORE
WINDS WILL CONTINUE ACROSS THE AREA, BUT WILL WEAKEN INTO TOMORROW,
WITH EASTERLY WINDS INCREASING TO AROUND 10 MPH THIS AFTERNOON AND
THEN DROPPING TO 5-10 MPH ON FRIDAY. THE ONSHORE FLOW AT THE
SURFACE COMBINED WITH S/SE WINDS ALOFT ON THE WESTERN EDGE OF A
MID LEVEL RIDGE TRANSPORTS DEEPER MOISTURE NORTHWARD ACROSS THE
AREA THROUGH LATE WEEK, LEADING TO RISING RAIN CHANCES ACROSS THE
AREA.
FOR TODAY, RAIN CHANCES (20-50%) REMAIN MOSTLY SOUTH OF A LINE FROM
ORLANDO TO THE CAPE, WHERE GREATEST MOISTURE (PW VALUES OF 1.7-2.0")
WILL RESIDE. ISOLATED ONSHORE MOVING SHOWERS WILL BE POSSIBLE ALONG
THE COAST, MAINLY SOUTH OF THE CAPE THIS MORNING, AND THEN ISOLATED
TO SCATTERED SHOWERS AND A FEW STORMS ARE FORECAST TO DEVELOP SOUTH
OF ORLANDO INTO THIS AFTERNOON. INTO FRIDAY, PW VALUES OF 1.9-2.1"
OVERSPREAD ALL OF EAST CENTRAL FLORIDA, WITH COVERAGE OF SHOWERS AND
STORMS INCREASING (POPS 50-60%), BECOMING SCATTERED TO NUMEROUS
PRIMARILY INTO THE AFTERNOON AND EARLY EVENING HOURS. MAIN STORM
THREATS EACH DAY WILL BE OCCASIONAL TO FREQUENT CLOUD TO GROUND
LIGHTNING, GUSTY WINDS UP TO 45 MPH AND LOCALLY HEAVY RAINFALL UP
TO 1-3". TEMPERATURES CLIMB TO SLIGHTLY ABOVE NORMAL, WITH HIGHS
IN THE UPPER 80S TO LOW 90S, AND OVERNIGHT LOWS IN THE LOW TO MID
70S.
SATURDAY-WEDNESDAY...WEATHER CONDITIONS RAPIDLY DETERIORATE INTO THE
WEEKEND AS TROUGH ALOFT SHIFTS INTO THE EASTERN U.S. AND PUSHES
FRONT THROUGH THE AREA. BREEZY TO WINDY CONDITIONS QUICKLY DEVELOP
INTO SATURDAY AS NORTHERLY WINDS INCREASE TO 15-25 MPH, WITH GUSTS
UP TO 30-40 MPH (STRONGEST ALONG THE COAST). WIND ADVISORIES WILL
LIKELY BE NEEDED FOR THE COAST INTO SATURDAY/SATURDAY NIGHT, AND MAY
EVEN EXPAND ACROSS INLAND AREAS DURING THE DAY SUNDAY AS NORTHEAST
WINDS LOOK TO STRENGTHEN FROM TIGHTENING PRESSURE GRADIENT BETWEEN
FRONT TO THE SOUTH AND STRONG RIDGE TO THE NORTH. SOME FORECAST
UNCERTAINTY DOES COME INTO PLAY LATER IN THE WEEKEND INTO NEXT WEEK,
AS MODELS SHOW A CUT-OFF LOW FORMING FROM THE ADVANCING TROUGH AND
DEVELOPING A STRONG AREA OF LOW PRESSURE AT THE SURFACE EITHER NEAR
(ECMWF) OR WELL OFFSHORE (GFS) THE MID-ATLANTIC COAST. EXACT
TIMING/LOCATION OF THIS DEVELOPING FEATURE COULD LEAD TO SOME
DIFFERENCES IN WIND DIRECTION AND OVERALL SPEED. HOWEVER, CURRENT
FORECAST LEANS TOWARD THE GFS, WHICH HAS MORE MODEL SUPPORT
CURRENTLY, MAINTAINING BREEZY TO WINDY NE WINDS THROUGH AT LEAST
EARLY NEXT WEEK.
MODELS NOW SHOW ADVANCING FRONT WILL PUSH OUT SOME OF THE DEEPER
MOISTURE ACROSS THE AREA, EVEN AS WINDS QUICKLY VEER ONSHORE. RAIN
CHANCES REMAIN HIGH UP TO 50-70% FOR MUCH OF THE AREA SATURDAY.
HOWEVER, THE GFS NOW HAS PW VALUES FALLING BELOW 1.5" BY SUNDAY.
STILL, THE STRONG ONSHORE WINDS WILL STILL PRODUCE ROUNDS OF
SCATTERED TO NUMEROUS SHOWERS THAT WILL BE ABLE TO PUSH ONSHORE
THROUGH LATE WEEKEND INTO EARLY NEXT WEEK. A FEW STORMS WILL ALSO
CONTINUE TO BE POSSIBLE, MAINLY SOUTH OF THE CAPE WHERE SOME
LINGERING INSTABILITY WILL PERSIST. PERSISTENT BANDS OF SHOWERS AND
ANY STORMS COULD LEAD TO LOCALLY HEAVY TO EXCESSIVE RAINFALL,
PRODUCING FLOODING ISSUES, MAINLY ACROSS THE TREASURE COAST. A
MARGINAL RISK FOR EXCESSIVE RAINFALL (LEVEL 1 OF 4) EXISTS ACROSS
THIS PORTION OF EAST CENTRAL FL INTO THE WEEKEND.
COOLER TEMPERATURES MOVE IN BEHIND THE FRONT, WITH HIGHS DROPPING TO
AS LOW AS THE MID 70 TO LOW 80S SUNDAY, AND THEN SLOWLY WARMING BUT
REMAINING NEAR TO BELOW NORMAL THROUGH THE MIDDLE OF NEXT WEEK. THE
STRONG ONSHORE WINDS WILL LEAD TO A PROLONGED PERIOD OF DANGEROUS
BEACH AND BOATING CONDITIONS. HIGH SURF, WITH BREAKING WAVES OF 9-12
FT OVER MULTIPLE TIDAL CYCLES WILL CONTRIBUTE TO MODERATE BEACH
EROSION, ESPECIALLY NORTH OF CAPE CANAVERAL. RESIDENTS AND VISITORS
SHOULD USE CAUTION NEAR THE BEACH AND REMAIN OUT OF THE WATER.
MARINE
ISSUED AT 256 AM EDT THU OCT 15 2026
TODAY-FRIDAY...FAVORABLE BOATING CONDITIONS PERSIST THROUGH FRIDAY.
HIGH PRESSURE NORTH OF THE AREA SHIFTS EAST THROUGH LATE WEEK, AS A
COLD FRONT MOVES INTO THE SOUTHEAST UNITED STATES. THIS WILL ALLOW
ONSHORE WINDS TO CONTINUE BUT WEAKEN, WITH EASTERLY WINDS UP TO 10-
15 KNOTS TODAY DIMINISHING TO 5-10 KNOTS TOMORROW. SEAS WILL REMAIN
AROUND 2-3 FEET. ISOLATED TO SCATTERED SHOWERS WILL BE POSSIBLE
ACROSS THE WATERS AS WILL A FEW STORMS, MAINLY SOUTH OF THE CAPE
TODAY, WITH COVERAGE OF THIS ACTIVITY INCREASING ACROSS THE ENTIRE
COASTAL WATERS INTO FRIDAY.
SATURDAY-TUESDAY...HAZARDOUS TO DANGEROUS BOATING CONDITIONS ARE
THEN FORECAST TO RAPIDLY DEVELOP BEHIND A PASSING FRONT INTO THE
WEEKEND. N/NE WINDS INCREASE TO 20-30 KNOTS ACROSS THE WATERS
SATURDAY AND THEN STRENGTHEN TO AROUND 25-30 KNOTS ACROSS THE ENTIRE
WATERS ON SUNDAY, WITH FREQUENT GUSTS TO GALE FORCE LIKELY. WINDS OF
THIS INTENSITY ARE THEN EXPECTED TO CONTINUE THROUGH EARLY NEXT WEEK
KEEPING DANGEROUS BOATING CONDITIONS IN PLACE. THESE STRONGER WINDS
WILL QUICKLY BUILD SEAS UP TO 10-14 FEET BY SATURDAY NIGHT AND
REMAIN AROUND THAT HEIGHT THROUGH EARLY NEXT WEEK.
SCATTERED TO NUMEROUS SHOWERS AND ISOLATED TO SCATTERED STORMS WILL
ALSO PERSIST ACROSS THE WATERS, WITH THIS ACTIVITY CONTINUING TO
PUSH TOWARD THE COAST AND ONSHORE, ESPECIALLY SOUTH OF THE CAPE.
