DISCUSSION

Issued at 151 AM EST Thu Dec 4 2025

Current-Fri...Surface high pressure weakens today across the region, though conditions stay mainly dry thru the period. Light and variable winds veer NE/ENE 5-10 mph today, but we may see a degree of variability for surface winds across the ECFL interior into the afternoon as the pgrad is very weak. Light winds tonight, then S/SW winds 7-12 mph (few higher gusts) developing into Fri. The next weather system will develop across the western Gulf with low pressure tracking across the northern Gulf late tonight/Fri. This should drag the next front into the FL Panhandle/north FL by sunrise Sat morning where it becomes quasi- stationary. Increasing moisture will pool along and ahead of this feature to the north of central FL. Partly cloudy skies into Fri, but expect increasing cloudiness across the I-4 corridor later in the period where moisture is deepest.

Gradual warming trend into late work-week with maxes today in the L70s along the Volusia coast and M-U70s across the I-4 corridor southward - perhaps some 80 degree readings near Kenansville southward inland from the coast. Near 80F to L80s prevail Fri and perhaps a few M80s southern Osceola-southwest Brevard southward west of I-95. For mins, slightly warmer tonight/Fri morning with U50s to L60s forecast, except M60s for barrier islands and coastal Martin County. Generally L-M 60s areawide Fri overnight/Sat morning.

Sat-Wed...The next front meanders across the north-central FL peninsula, but appears to finally get a nudge southward Sun overnight/early Mon. Deepest moisture still pools near this boundary with PWATs 1.75-2.00" across the area on Sun. We keep ISOLD-SCT (20- 50%) showers in the forecast Brevard-Osceola northward Sat-Sat night, increasing values areawide 40-60% on Sun and around 40% Sun night. Showers (15-30%) end north-south thru the day on Mon from near Orlando southward. There will also be an ISOLD threat of thunder this weekend - mainly on Sun, with a few lingering storms still possible along the Treasure Coast on Mon as moisture is slow to scour out. Weak high pressure gradually settles in behind this latest weather system into mid next week with mainly dry conditions areawide Mon night-Wed across land.

Highs remain above normal in the U70s/L80s (few M80s southward) for Sat-Sun (pre-frontal). Cooler conditions return on Mon-Wed (post- frontal) in the U60s to L-M70s. Lows in the 60s areawide Sat/Sun overnight periods. Generally 50s areawide Mon overnight/Tue, except U40s for portions of north Lake/northwest Volusia counties. Tue night will be the coldest with L-M40s north/west of I-4 with U40s to around 50F southward thru much of the interior (W of I-95) & Volusia coast. L-M50s further south along the Space/Treasure coasts.

MARINE

Issued at 151 AM EST Thu Dec 4 2025

Today-Mon...A developing long period ERLY swell ~10 seconds continues into Sat. Winds and seas become favorable into late week as light northerly winds early today begin to veer more onshore through the day and become southerly thru Fri and SW Fri night/Sat and more SW/W Sat night/Sun ahead of an approaching front. Winds become NW/N on Mon (post-frontal) with speeds increasing to 15-20 kts and higher gusts. Seas 2-3 ft very near shore thru Sat, but may increase to 5 ft well offshore Cape northward Sat overnight/Sun and 6 ft offshore Sun night/Mon. Seas are forecast to build further to 7 ft over the offshore legs Mon overnight. Generally dry thru Fri night, but increasing shower chances and ISOLD lightning storms may enter the picture again Sat-Sun as moisture increases with approaching front. Precip gradually winds down later on Mon.

AVIATION

(12Z TAFs) Issued at 625 AM EST Thu Dec 4 2025
