Currently - Tonight
Sct slow-moving storms, initially a little closer to the coast than previous days will drift inland through nightfall with best chance for storms through around 9 PM remaining across the interior. Locally heavy rainfall up to 2 inches, and occasional lightning will remain the primary concerns. Expect a general decrease in coverage after nightfall, with some marine based activity possibly affecting portions of the the Treasure Cst into tonight in onshore flow. Expect seasonal readings in the M-U 70s overnight, with mostly clear skies developing after midnight.

Thu-Fri...Atlantic ridge axis remains across central Florida into late week, with a relatively light low level S/SE flow continuing. Sea breeze boundaries will move inland each day, leading to the development of isolated to scattered showers and storms each afternoon, with boundary collisions between outflow and sea breeze boundaries enhancing convection over the interior late in the day. Greater coverage of this activity will be west of I-95 each day, with rain chances a little higher across the area on Thursday compared to Friday, as models are indicating some drier mid-level air moving northwest into the region. Rain chances on Thursday range from 30-50 percent across much of the area, and then 20-40 percent on Friday. Drier air aloft may allow for some storms to become strong, producing gusty winds of 40-45 mph and frequent lightning strikes, mainly with any inland boundary collisions.

Ridge aloft extending eastward across the Southeast U.S. will keep temps near to above normal, with highs in the low 90s along the coast and low-mid 90s across the interior.

Sat-Tue...Atlantic ridge axis shifts south into the weekend and remains south of the area through early next week, as a weak front shifts south through the southeast U.S. and stalls across north FL. Moisture will gradually increase through the period, especially ahead of the front as it nears the area later into the weekend and early next week. This will lead to rising rain chances from around 30-50 percent on Saturday, up to 50-60 percent on Sunday and then 60- 70 percent Monday and Tuesday. Low level W/SW flow will focus afternoon convection and late day boundary collisions toward east central FL, with scattered to numerous showers and storms developing and moving east to northeast and offshore. Temps will remain near to above normal, with highs in the low-mid 90s and overnight lows in the 70s.

Marine
Currently - Tonight
Favorable conditions. Onshore to SE winds 10-15 KT this afternoon, becoming light SE less than 10 kt across the northern waters tonight. SE winds 8 to 12 kts across the southern waters overnight due to the Atlantic ridge axis over N/Central FL. Isolated showers and a few storms possible overnight primarily south of Sebastian Inlet. Seas around 2-3 FT.

Thu-Sun...Atlantic ridge axis will remain across central FL through late week, before shifting south into the weekend. S/SE winds will largely remain in place through the period, with S/SW winds during the overnight and morning hours into the weekend. Wind speeds will range from 5-10 knots in the morning and increase to 10-15 knots each afternoon and evening as sea breeze forms and shifts inland. Seas 2-3 feet.

Isolated storms will be possible over the waters, mainly during the overnight and morning hours through late week, as greatest coverage of afternoon showers and storms will remain focused across the interior of central Florida. However, there will be a greater potential for offshore moving storms in the afternoon and early evening hours this weekend.
