KEY MESSAGES

Issued at 255 PM EDT Fri Oct 2 2026

- Scattered to numerous showers and storms will be possible each day across east central Florida through this weekend and into next week. Minor flooding remains the main hazard along with lightning strikes and gusty winds.

- Generally favorable boating conditions this weekend into early next week will deteriorate into the middle of next week as a low develops north of the waters.

- Near to slightly above normal temperatures are anticipated to continue across east central Florida through this weekend. Peak heat indices nearing and even exceeding 100F will be possible in some spots.

DISCUSSION

Issued at 255 PM EDT Fri Oct 2 2026

Through Tonight...Persistent southeast flow coupled with the moist air mass in place has produced scattered showers and isolated storms across east central Florida this afternoon. Continued shower and storm development is forecast over the next few hours, with the same storm threats all forecast, including occasional to frequent lightning strikes, wind gusts up to 50 mph, and quick rainfall accumulations of 1-3". Minor, localized flooding remains a concern. While coverage is generally anticipated to diminish in coverage into the evening and overnight hours, some hi-res guidance continues isolated activity across the peninsula through the overnight hours and into early Saturday, especially along the coast where onshore- moving showers are possible. Flooding will remain a concern through the overnight hours, especially in places that have seen rainfall today. Temperatures either are peaking or peaked prior to rainfall in the upper 80s, with conditions tonight remaining muggy with lows in the 70s.

Saturday-Sunday...Mid-level ridging is forecast to remain in place across the Florida peninsula this weekend, translating to broad high pressure across the western Atlantic at the surface. The ridge axis is forecast to remain well north of Florida, maintaining east to southeast winds locally. This onshore flow will continue to advect moist air towards east central Florida, keeping PWATs of 2-2.3" through this weekend. This moist air mass coupled with the persistent onshore flow will favor continued development of showers across the local Atlantic waters through the evening and early morning hours, with coverage increasing and expanding towards the peninsula through the late morning and afternoon hours. Kept PoPs generally between 30-50% on Saturday, increasing to 40-70% on Sunday as moisture continues to advect to the area. Isolated to scattered storm development will be possible each day, though the moist profile and limited forcing will keep chances limited. Occasional lightning strikes, wind gusts up to 45 mph, and quick rainfall accumulations of 1-3" will be possible each day. Minor, localized flooding in spots cannot be ruled out, especially given saturated soils from recent rainfall. Storm chances will wane into the overnight hours with lingering shower chances across the local Atlantic waters.

The warm, moist air mass will support temperatures remaining near to slightly above normal, with highs climbing into the mid 80s to low 90s. These temperatures combined with humidity will produce peak heat indices of 100F and greater through the weekend, so adequate hydration and breaks in the shade are strongly encouraged if spending extended periods of time outdoors. Overnight, temperatures will range between the low to mid 70s.

Monday-Thursday...Mid-level ridging across the eastern US will weaken into early next week as broad troughing builds and extends across the southeastern US. This troughing aloft will support a cold front drifting southward across the southeast US, with the front anticipated to stall near to just north of Florida through next week. The development of a low along the stalled boundary directly near the northeastern Florida coast looks to be possible on Tuesday based on guidance, with the low then lifting northeastward across the Atlantic waters. This overall set-up will maintain a deep pocket of moisture across the Florida peninsula, with PoPs forecast to remain high (70-90%) through next week. Heavy rainfall will be the primary concern with activity and WPC is already beginning to include northern portions of east central Florida under Marginal risks (1/4) of excessive rainfall on Monday and Tuesday. Minor, localized flooding in spots will be possible, especially given the saturated soils from recent rainfall. Storm development will also be possible with activity, and lightning and gusty winds cannot be ruled out. Greater ideas on exact rainfall chances and storm hazards will become clearer as time moves on. Temperatures are forecast to remain near to slightly above normal on Monday in the upper 80s to low 90s, with a chance for peak heat indices to once again reach 100F in spots. A temperature gradient from north to south is forecast Tuesday through Thursday due to the stationary boundary, with afternoon highs remaining a bit closer to normal. Overnight lows will remain close to normal through the period.

MARINE

Issued at 255 PM EDT Fri Oct 2 2026

Broad high pressure across the Atlantic is forecast to remain in place through this weekend, sliding more offshore into early next week as a cold front drifts south across the southeastern US and adjacent Atlantic waters. The front is then forecast to stall across Florida, and a low is anticipated to develop early to mid week off the northeastern Florida coast, which is anticipated to bring deteriorating boating conditions locally starting the middle of next week.

Generally favorable boating conditions are forecast through this weekend with seas of 2 to 4 feet and southeast winds 10 to 15 knots. By Monday, winds become more southerly around 10 knots. Tuesday, the low is forecast to develop, with deteriorating conditions beginning on Tuesday evening as winds become more west to north, increasing to 5 to 25 knots across the Volusia waters. Seas rapidly increase Tuesday night and spread southward through next week, with wave heights anticipated to reach 5 to 10 feet, highest across the offshore waters. Rain chances will remain moderate to high (40-90%), highest on Monday and Tuesday. Isolated to scattered storm development is anticipated with activity, and lightning strikes, wind gusts in excess of 30 knots, heavy downpours, and locally higher seas will all be possible.

AVIATION

(00Z TAFs) Issued at 713 PM EDT Fri Oct 2 2026

Guidance suggests that some showers and isolated lightning storms will redevelop along the coast tonight, esp for MLB to SUA. Otherwise, trending quieter with predominant VFR. There is a low chance for some brief lower CIGs late tonight due to the high ambient moisture. On Saturday, showers may linger along the coast through midday before the focus shifts toward the interior and western peninsula in the afternoon. Carried low-confidence VCTS for MCO, though high-res members generally give the best storm chances to locations west of the terminal on Sat PM. Winds continue from the E/SE up to 12 kt.
