DISCUSSION.

. Cool Front To Bring Rapidly Deteriorating Boating Conditions To The Atlantic Waters Tonight .

Today . Mid to upper level high pressure over the local area will weaken today, as a trough pushes through the eastern US. As the high pressure weakens, so will onshore flow, allowing the east and west coast sea breezes to meet across the interior this afternoon. However, with moisture lacking and PWATs below 1.5", not expecting any precipitation to develop along the collision. Thus, another dry day expected under partly to mostly sunny skies. Temperatures will be above normal again, with highs rising into the upper 80s to low 90s. Leesburg will once again have a shot at a record high, with the current forecast within 1 degree of the 92 degree record, set in 2018.

Tonight . As the aforementioned trough continues eastward, it will drag a cool front through the local area late this evening into tonight. Expecting this to be a mostly dry FROPA thanks to the lower moisture over the area; however, a slight chance of showers will exist north of Orlando/Titusville through a little after midnight. Then, showers and a thunderstorm or two will remain possible offshore overnight, as the front continues southward through the area. Winds veering northerly behind the front and increasing to around 10mph prior to daybreak. Will not see a relief in overnight temperatures just yet, as lows are expected to remain in the upper 60s to around 70. Although, mid-60s will be possible north of I-4.

Sun . The cool front and assocd band of moisture is forecast to be over southern sections at daybreak with isolated showers pushing south along the coast, roughly Cape southward. Drier air will overspread northern sections and skies will quickly clear there. Slight onshore component will keep some clouds along the coast and will hold onto a chance for showers in Martin/St Lucie counties into the aftn due to closer proximity of the Gulf Stream. Breezy north to northeast winds 15-20 mph, with a few higher gusts along the coast. Max temps will hold in the upper 70s along the Volusia coast, with low to mid 80s elsewhere. Lower dewpoints across the north/interior will produce comfortable humidity. Lows Sunday night/Monday morning should dip into the upper 50s in Lake/NW Volusia counties with lower 60s elsewhere interior and mid to upper 60s coast. These should be the coolest temps of the week.

Mon-Fri . High pressure building into the Southeast, as the weakening front continues southward into far southern Florida and the Keys. Locally, drier air with PWATs below 1" will keep rain chances out of the forecast all areas thru Tuesday. Very gradual moisture return may produce isolated showers across far southern sections Wed but even there most areas will remain dry. Moisture will increase from the SW late in the week as high pressure to the north pushes seaward and a weak front pushes into the deep South. Have shown a trend of higher PoPs, 20 percent north/30 percent south Thu then 40 percent north/50 percent south Fri.

Gradually veering wind flow from NE to E as high pressure to the north shifts east. Temperatures will warm through the period, with highs in the low to mid-80s on Monday returning to the mid to upper 80s during mid to late week. Min temps will also tick upward due to easterly flow keeping mins in the lower 70s coast, while inland areas return to the mid to upper 60s.

AVIATION. VFR conditions prevailing through the period. Onshore flow easing today ahead of a cool front passage tonight, with a dry sea breeze collision expected across the interior early in the evening. A few isolated showers will be possible north of KMCO/KTIX late this evening as the front approaches, but confidence is too low to include a mention in the TAF. Winds becoming northerly behind the front, increasing late tonight to around 8-10kts.

MARINE. Today . Dry conditions today as a trough moving through the eastern US weakens high pressure over the local area. Northeast flow slackening, becoming 5-10kts in the afternoon. Seas 2-3ft.

Tonight . Rapidly deteriorating boating conditions late this evening, as a cool front passes through the local Atlantic waters through tonight. Winds veering N behind the front, increasing to around 20kts north of Sebastian Inlet by daybreak and 10-15kts offshore from the Treasure Coast. Seas will begin to build, but will remain mostly 2-3ft, though 4-5ft will be possible offshore of the Volusia Coast towards morning. A Small Craft Advisory will take effect at 2am tonight for the nearshore and offshore waters north of Sebastian Inlet.

Sun-Wed . Hazardous conditions expected Sunday/Sunday night with N/NE winds 17-20 knots so a Small Craft Advisory has been posted for all the local Atlc waters. Seas 4-5 ft near shore and 6-7 ft offshore/Gulf Stream. Winds will veer NE around 15 knots Monday with seas dropping below 7 ft in the Gulf Stream but will likely need to carry a Caution headline there. On Tue-Wed, winds will veer a little more easterly 12-15 kt as high pressure translates eastward over the western Atlc. Seas subsiding 3-4 ft Tue and mostly 3 ft Wed.

HYDROLOGY. Light W to NW winds today will increase out of the N-NE tonight and Sunday behind a cool front. Coupled with autumnal high astronomical high tides, the St Johns River at Astor will remain at or near Minor Flood stage (around 2.3 ft) through early next week.
