Issued at 256 AM EDT Thu Oct 15 2026 - Rain chances gradually rise today into Friday, with temperatures slightly above normal. - A wet and windy weekend is forecast behind a passing front, with conditions persisting into early next week. Wind Advisories are likely and flooding concerns return, especially along the southern coast. - Dangerous boating conditions, high surf, and moderate beach erosion are expected behind the front this weekend and into early next week. Residents and visitors should use caution near the beach and remain out of the water beginning this weekend. && .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 topush 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. && .AVIATION... (18Z TAFs) Issued at 125 PM EDT Thu Oct 15 2026 Onshore flow prevails this afternoon, with low chances for showers and storms from MLB southward along the coast. Removed PROB30s at FPR and SUA given lower confidence in activity, but will monitor and amend as needed. Winds become light and variable overnight, with some spots along the coast maintaining an onshore component. Low chance for some onshore-moving VCSH at VRB, FPR, and SUA tonight. Winds remain light and variable across the interior beyond 15Z tomorrow, with winds picking up out of the ESE along the coast after 17Z as the ECSB develops and pushes inland. Another afternoon of showers and storms will be possible tomorrow, with a mention of VCTS at MCO after 18Z for now, with additional terminals likely being added with the next forecast package. && .PRELIMINARY POINT TEMPS/POPS...
