DISCUSSION

Issued at 217 PM EDT Tue Aug 25 2026

Current-Tonight...Another warm & humid day with max temps in the L- M90s this afternoon and peak heat indices above 100F, still remaining below Heat Advisory criteria. Residents and visitors are strongly encouraged to practice heat safety to avoid developing heat illness. Weak mid-level troughing continues across north FL and will enhance diurnal shower/lightning storms this afternoon and evening. Highest chances (50-70%) from Osceola-Brevard County northward where moisture is deepest, and generally 20-40% PoPs southward. The ECSB will develop and push inland this afternoon with strongest boundary collisions across the interior to include Volusia County. Storm motion is weak/erratic and some storms may push back to the Volusia/Brevard coast this evening. Primary storm impacts remain local strong wind gusts (45-55 mph) in a few storms, frequent lightning strikes, and torrential downpours leading to quick 1-3" rainfall totals. Localized amounts of 4-5" may be possible and the Weather Prediction Center has outlined central Brevard - central Osceola County northward for a Marginal Risk of Excessive Rainfall this afternoon/evening. Activity will wind down through mid/late evening and cloud-cover will thin thru the overnight. Min temperatures fall into the M70s with conditions humid.

Wed-Wed Night...Surface ridge axis will advance northward across central FL. Light morning southerly winds will "back" onshore in the afternoon with sea breeze formation and push inland. ISOLD-SCT showers storms with the ECSB near the coast - earlier development and quicker movement inland south; the WCSB will promote similar initial coverage across our western coverage warning area in the afternoon. A late day/evening sea breeze collision likely from near Lake George thru Seminole County, Greater Orlando Metro and south across the Kissimmee River. PoPs 60-70% nearly areawide.

High temps continue in the L-M90s with peak heat indices north of 100F. Overnight lows consistent in the M70s with conditions muggy.

Previous Extended Forecast Discussion Slightly Modified.

Thu-Fri...Sea-breeze-driven showers and storms are likely each day as moisture values (PWATs 2"+) return to normal to slightly above. A few storms will likely develop near the coast in the early afternoon before a collision over the interior sparks the greatest coverage and intensity late in the afternoon or by early evening. Weak offshore flow in the mid-levels may drive some lingering storms back toward the east coast in the evening. Each day, rain and storm chances range from 50-70%. Our general summertime thunderstorm hazards are expected, with frequent lightning, wind gusts from 40 to 45 mph, and localized flooding the main threats.

Seasonably hot temperatures and humidity levels will continue.

Weekend-Early Next Week...Rather typical late summer weather is expected to persist as August wraps up across east central Florida. Light onshore flow tries to become established this weekend as high pressure becomes situated just to our northeast. With no interruption to the moist airmass overhead, expect scattered to numerous afternoon and evening storms, with the focus likely becoming more over the interior with slightly less coverage near the coast. Hot and muggy each afternoon before storms begin to form.

MARINE

Issued at 217 PM EDT Tue Aug 25 2026

Generally favorable boating conditions continue across the local waters outside of shower/lightning storm activity through this week. The Atlantic surface high slowly lifts north across the waters this week. Light offshore winds 5 to 10 kts during the overnight and morning hours increase to 10 to 15 kts and shift to out of the southeast during the afternoon as the east coast sea breeze develops each day and moves well inland. Seas remain generally between 1 to 2 ft (occasionally 3 ft - esp this weekend), with the highest seas focused across the offshore waters. Isolated to scattered shower and lightning storm development will be forecast, with activity affecting the intracoastal/near shore Atlc waters each afternoon/evening. Additional shower/storm development overnight across the Gulf Stream waters will be possible. Storm hazards will include frequent cloud-to-water lightning strikes, wind gusts in excess of 30 kts, heavy downpours, and locally higher seas.

AVIATION

(00Z TAFs) Issued at 720 PM EDT Tue Aug 25 2026

Showers and storms near TIX and MLB will continue to move offshore through 01Z. Maintain TEMPOs through 01Z at both sites for VIS and CIG reductions due to TSRA and wind gusts. Elsewhere and beyond 01Z at TIX and MLB, VFR conditions prevail with light southerly flow becoming variable at times. Winds pick up out of the SE along the coast after 15Z as the east coast sea breeze develops and moves inland, becoming SE at the interior terminals after 18Z. Shower and storm chances also increase with the development of the sea breeze, so have added mention of VCTS at all terminals as the winds become SE. Will likely need TEMPOs/PROB30s, but too early to include with this package.
