KEY MESSAGES

Issued at 202 PM EDT Wed May 27 2026

- Scattered to numerous showers and storms near and west of Orlando into this evening. A few storms may become strong, with wind gusts exceeding 50 mph and frequent lightning.

- The High Risk of life-threatening rip currents continues today at all Atlantic beaches of Central Florida. Please stay out of the surf.

- An unsettled and humid weather pattern kicks off on Thursday, lasting at least into early next week. High coverage of afternoon and evening storms is expected, even at the coast. There is at least a limited threat of localized flooding in urban and poorly drained areas from repeated rounds of heavy rain over several days.

DISCUSSION

Issued at 202 PM EDT Wed May 27 2026

Rest of Today-Tonight...A bit higher coverage of late morning and early afternoon showers and storms than previous expected. However, the overall forecast remains on track for the remainder of the day and into tonight.

High pressure off of the Southeast US coast is producing generally southerly steering flow, made clear by the northward motion of ongoing convection. However, breezy southeasterly flow 15-20 mph along the coast, with 25-30 mph has developed behind the sea breeze. Expect the sea breeze to continue inland this afternoon, with a collision over the center of the peninsula, near to just west of the Orlando metro. Scattered to numerous showers and storms (PoPs 50-70%) are forecast. Lingering drier air in the mid- levels, producing DCAPE values between 900-1100 J/kg will support the threat for isolated stronger wind gusts 50+ mph, in addition to lightning strikes and locally heavy rainfall. Peak convective timing looks to be between 6-10 PM, though a few showers and storms may linger through midnight to early morning.

Then, CAMs suggest additional showers and storms developing over the eastern Gulf, drifting into the local forecast area towards morning. This eastward movement will be generated by increasingly southwesterly steering flow aloft, which should conversely help keep most convection offshore along the Treasure Coast compared to previous days. Tonight, overnight lows remain in the 70s.

Thursday-Sunday...A trough moving off of the Northeast US coast will usher in a pattern change that looks to persist through at least mid-week next week. The aforementioned ridge is nudged southward by the trough Thursday, elongating near the Straits of Florida through the weekend. Light southwesterly to westerly winds develop, which will aid in daily sea breeze collisions over the eastern half of the peninsula, near the coast.

That alone would suggest an increase in PoPs. However, deep tropical moisture is forecast to advect into the area from the Gulf, increasing PWATs to around 2+" through at least Saturday. Aided by weak passing shortwaves aloft, PoPs look to become widespread 70-80% Thursday through the weekend. Despite the high PoPs, most convection looks to occur in the afternoons and into the evenings before moving offshore, as opposed to true washouts. Exact rainfall accumulations will be dependent on where individual showers and storms setup. Although, widespread accumulations 1.5-2.5" are expected, with isolated totals 3+". Rainfall will be beneficial due to ongoing drought conditions. But, localized flooding concerns may develop in areas that see multiple rounds of heavy rainfall over several days, especially urban areas.

Temperatures are forecast to see little change into the weekend, with highs in the upper 80s to lower 90s and overnight lows in the 70s. High humidity will lead to heat indices in the upper 90s to low 100s.

Next Week...Uncertainty lingers next week, as models continue to try to resolve an approaching cool front. Whether this front stalls near the area and where it does so are the main differences in the global models. Regardless, high coverage of showers and storms (70-80%) looks to persist, with southwesterly flow continuing to favor a dominant west coast sea breeze. A more organized area of locally heavy rainfall will be the main threat along the front, which may exacerbate any flooding concerns that develop through the weekend.

MARINE

Issued at 202 PM EDT Wed May 27 2026

Poor boating conditions south of Cape Canaveral this afternoon due to southeasterly winds 15-20 kts. Winds slacken this evening and into tonight, as high pressure off of the Southeast US coast begins to shift southward. Prevailing flow then becomes southwesterly to westerly into the weekend, though a weak sea breeze looks to develop along the coast in the afternoons through Friday. High coverage of showers and storms (PoPs 50-70%) develops Thursday into early next week. Convection is mainly forecast to develop near the coast in the afternoons, drifting offshore through the evening and overnight hours. Seas 4-5 ft this afternoon become 1-3 ft through the weekend.

AVIATION

(00Z TAFs) Issued at 755 PM EDT Wed May 27 2026

Sct SHRA/TSRA continue north thru ISM/MCO, largely staying west of LEE for now. A boundary ahead of this broken TS line is moving north and could develop additional SHRA/TSRA thru 02z or so. Confidence is lower in the fcst overnight into Thu. with varying model solutions. VCSH seems like a fair start overnight for inland locations. Cannot rule out a brief SHRA at SUA before 11-12z Fri. but not included at this time.

TSRA mainly after 17z-19z Thu., as the west coast sea breeze pushes inland. There is lower confidence in TS impacts for DAB/SFB/MCO/ISM, but still warrants VCTS. Focus will be on TIX southward to FPR/SUA after 21z for TSRA CIG/VIS/gusty wind impacts, which could linger beyond the TAF period.

Outside of storms, light winds overnight turn SW after 14z, around 10 kt (higher at coast). Winds veer SE at the coast after 16-18z.
