UPDATE
Issued at 917 AM EDT Fri Sep 20 2024

A few showers over the offshore Atlantic waters this morning, otherwise, mostly quiet across east central Florida. Patchy fog earlier this morning has since dissipated with the daytime heating. Expect fairly similar conditions today as yesterday, as a weak trough extends down across the US east coast, including the Florida peninsula. Light northeast winds this morning will become east- northeast by this afternoon and increase to 5-10 mph with a few gusts to around 20 mph possible. The 10Z XMR sounding shows a PW value around 1.5", with drier air in the mid and upper levels.
The GOES derived PW is in good agreement, with PW values of 1.4-1.5" across east central Florida. This will support isolated to scattered showers and lightning storms this afternoon. The greatest moisture will focus from Orlando/Cape Canaveral southward, with 20-30 percent chance of showers/storms near I-4 and the Space Coast and 40-50 percent chances for the Treasure Coast. Main storm threats today will be occasional to frequent lightning strikes, gusty winds 40-45 mph, and brief torrential rain which could cause minor flooding. Afternoon highs will be in the upper 80s to around 90 degrees.

Tonight, mostly dry conditions are expected with a few showers possibly skirting the coast in the NE flow. Overnight lows will be in the low to mid 70s. Forecast remains on track with no major changes.

Boating conditions slowly become poorer over the next few days as onshore winds increase. As high pressure settles into the Appalachians, northeast winds freshen to 8-13 KT today through the weekend. There is a low to medium chance for showers and a few storms, though offshore-moving storms look less likely. By early next week, winds turn more easterly at 10-15 KT. Seas 2-4 FT through Saturday before building to 3-5 FT Sunday-Tuesday, largely driven by a northeast swell at 9-11 sec.
