Marine Weather and Tide Forecast for Limestone Creek, FL

PREVIOUS DISCUSSION
Issued at 215 PM EDT Sat Jun 21 2025

Tonight-Sunday...East coast sea breeze will continue to shift westward, with isolated to scattered showers and storms developing mainly across the interior through late afternoon, and then gradually diminishing through sunset. Mostly dry conditions are then forecast into the rest of tonight. However, isolated to scattered onshore moving showers and a storm or two will continue to be possible, mainly along the Treasure Coast through the overnight and early morning hours of Sunday. Will therefore keep a 20-30 percent chance of showers and storms across this region into tonight.

Ridge axis of high pressure will remain north of the area, with a deep onshore flow across the area. Low level easterly flow looks to even increase slightly, which should lead to earlier development and a little faster inland motion of the east coast sea breeze tomorrow.
Morning will start off with the potential for isolated to scattered onshore moving showers and a few storms along the coast, but then scattered convective coverage will then focus inland into the afternoon. Greatest rain chances (up to 50%) will be across the Treasure Coast and Okeechobee County where PW values will be higher (up to 1.8-1.9"). Farther north, rain chances will range from 30-40 percent. Drier air aloft will continue a low threat of a few stronger storms, with the main threats being frequent lightning strikes and strong wind gusts to 40-50 mph. Easterly steering winds will remain weak, which may allow for some locally heavy rainfall amounts of 1-2 inches with slow moving storms. Seasonable summer- time highs continue tomorrow, with highs in the upper 80s/near 90 at the coast and low 90s inland, with peak afternoon heat index values around 98-102F.

Storms will again diminish and shift west of the area through sunset, with mostly dry conditions again forecast into Sunday night.
The exception will be along the coast, from Brevard County southward where isolated onshore moving showers/storms will again be possible (chance of rain 20-30 percent).

Monday-Friday...Ridge axis of high pressure over the west Atlantic will stay north of the area through at least the middle of next week. Aloft, a strong mid-level ridge centered across the Mid- Atlantic states will remain extended across the southeast United States. This will continue a deep onshore flow across the area through Wednesday, with drier air building in from the east. PW values are forecast to fall to 1.5-1.6" on Monday and below 1.5" through midweek (with GFS showing values as low as 1.1-1.2" on Wednesday). This will lead to lower than normal storm coverage through this timeframe, with rain chances 30-40 percent across much of the area Monday-Tuesday and as low as 20-30 percent on Wednesday.
Overall trends should favor isolated to scattered onshore moving showers in the morning focusing inland each afternoon with the westward moving east coast sea breeze. Any late day boundary collisions should focus toward the west coast of the Florida peninsula, with mostly dry conditions across east central Florida each evening and overnight. Highs remain hot, but close to normal values, ranging from the upper 80s/around 90 degrees at the coast to low 90s inland (some mid 90s well inland on Wednesday). Drier air will keep peak afternoon heat index values closer to normal as well, with values up to 98-102F each afternoon.

An increase in moisture is forecast into late week, as ridge axis settles southward across central Florida. This will lead to a gradual rise in rain chances, up to 30-40 percent on Thursday and 50- 60 percent on Friday. However, greatest storm coverage will continue across the interior where sea breeze/outflow boundary interactions occur. Temperatures will also rise into late week, with highs reaching the low 90s at the coast and mid 90s across much of the interior. The increase in moisture and temps will also lead to more humid conditions, with afternoon peak heat index values around 100- 105F.

Tonight-Thursday...Boating conditions will overall remain favorable through the remainder of the weekend into next week. Ridge axis of high pressure over the west Atlantic will remain north of the area, maintaining a gentle to moderate E/SE breeze across the waters. Wind speeds are forecast to generally remain below 15 knots, with seas ranging from 2-3 feet. Isolated to scattered showers and storms will develop over the waters, especially during the nighttime and morning hours, but developing afternoon convection should focus inland and toward the western Florida peninsula. Main threat from storms will be gusty winds and cloud to water lightning strikes.

Issued at 703 PM EDT Sat Jun 21 2025

VFR conditions prevailing. An early end to convection once again this evening. However, CAMs suggest showers (and perhaps a few storms) developing over the Atlantic waters and moving into the Treasure Coast (VRB/FPR/SUA) overnight. This activity is forecast to begin at SUA around 6Z, then spread northward through the early morning hours. Showers will reach TIX/MLB by around 14Z, before VCTS becomes the primary threat between 14-16Z. The lowest confidence in activity is near DAB. Have forgone a VCSH/VCTS mention at this time, but this will be monitored. Stout onshore flow will push scattered showers and storms into the interior through the afternoon, with an early end forecast once again for the interior by around 22-0Z. Winds 9-12kts, with occasional gusts to around 20kts at the coast.
