DISCUSSION
Issued at 310 PM EDT Fri May 17 2024

...Near Record Temperatures Saturday with Heat Index Values in the 100-110 Degree Range...

Currently-Sunday... Current local radar imagery shows mostly dry conditions across east central Florida after an active morning and early afternoon with scattered showers and lightning storms which moved through areas mainly along and to the north of Lake Kissimmee to Melbourne. Currently, there are isolated showers over the offshore waters with partly to mostly cloudy skies and dry conditions elsewhere. However, guidance continues to show isolated showers and lighting storms developing into the late afternoon and evening hours along sea breeze boundaries late this afternoon and evening to the south of Orlando which will have the potential to produce gusty winds and cloud to ground lighting strikes. Skies are forecast to become mostly cloudy into the early morning hours leading up to daybreak with low stratus and patchy fog forecast.
Visibility will have the potential to drop to 1 mile or less at times, mainly between 4am and 9am over Lake, western Seminole, western Orange, and western Osceola counties.

A mid/upper level ridge will build over the state of Florida tomorrow with 500mb heights expected to reach 592dm over south- central Florida. Mostly sunny to partly cloudy skies are forecast.
Isolated to scattered showers and storms are forecast to develop into tomorrow afternoon with the greatest chance (PoPs ~ 40%) along I-95. The primary hazards will be gusty winds and cloud to ground lighting strikes. Southwest winds are forecast to back onshore near the coast and slightly inland into the afternoon as the east coast sea breeze pushes inland and collides with the west coast sea breeze to the west of I-95. Wind gusts up to 20-25mph from the west- southwest are forecast well inland and from the southeast near the coast. Afternoon highs are forecast to reach the low to upper 90s with heat index values in the 100-110 range with the highest values to the south of Orlando.

Modified Previous Discussion

By Sunday, a surface cold front approaching the area looks to bring our best opportunity for widespread rainfall. 850mb winds increase in the afternoon to around 30-40 kt, building bulk 0-6km shear values to around 50-60 kt, especially from Cape Canaveral southward.
As a mid level trough sweeps across north-central Florida, model soundings suggest mid level lapse rates around 6.5 C/km and 500mb temps cool to -10C. It would not be all too surprising to see a few storms become strong to marginally severe on Sunday, but again, stay tuned as we work to fine tune the forecast in the next 24-48 hours.
One benefit to high chance/likely PoPs on Sunday will be cooler afternoon temperatures in the upper 80s to low 90s. Rain and storms will gradually wind down Sunday night into early Monday morning as the cold front pushes south of the area.

Monday-Thursday...An occluding low pressure system off the Carolina coast will drift seaward through mid week, as high pressure builds from north to south over Florida. Despite dialing Monday's PoPs back a bit for this package, they actually came in a bit higher than the previous forecast, despite models still showing relatively drier air. Low-end rain chances look to linger through Tuesday, especially near the immediate coast, then drier conditions from the middle to latter part of next week. With flow veering out of the north early this week, cooler (relatively speaking) daytime highs are forecast to approach near normal values for mid to late May, but then temperatures begin to climb again Thursday and Friday.

MARINE
Issued at 310 PM EDT Fri May 17 2024

Currently-Saturday... Favorable boating conditions are forecast through Saturday as high pressure builds over the state of Florida.
Southeast winds at 8-14kts will veer offshore overnight. Winds will then back south-southeast into the afternoon Saturday at 10-15kts.
Seas are forecast to build to 1-2ft with up to 3ft offshore.
Scattered showers and isolated lighting storms are forecast into this evening which will have the potential to produce gusty winds and cloud to water lighting strikes. Scattered showers and lighting storms are forecast again Saturday afternoon with the potential to produce wind gusts up to 40mph and cloud to water lighting strikes.

Sunday-Tuesday (Modified Previous Discussion)...High rain and storm chances continue ahead of an approaching cold front. By Sunday, surface winds become SW 10-15 kt along and ahead of the front as it moves across the waters. The highest coverage of scattered showers and lightning storms is expected Sunday. Winds begin to turn out of the N Monday afternoon behind the front. Seas generally 1-2 ft Saturday, 2-3 ft Sunday, except where locally higher in the vicinity of lightning storms.

Fog which developed from TIX southward early this morning has mostly been MVFR VIS, occasionally falling to IFR. Fog is forecast to continue to lift over the next hour or so. Have kept mention of VCSH at DAB/LEE for a band of diminishing showers approaching the terminals later this morning. Not enough confidence to mention VCSH further southward. Tricky wind forecast today due to various boundaries traversing the area. Predominant winds are forecast out of the southwest, generally backing southward. East winds developing from MLB south with the development of the sea breeze. Winds can become variable at times through the day, generally remaining 10 kts or less.
