KEY MESSAGES

Issued at 120 PM EST Tue Dec 9 2025

- Marine conditions will improve a little later today, but with poor boating conditions persisting through midweek. Inexperienced mariners operating smaller vessels should avoid navigating these areas.

- Mostly dry weather is expected to continue in the upcoming days, with high temperatures reaching the 60s, and lows mostly in the 50s.

DISCUSSION

Issued at 120 PM EST Tue Dec 9 2025

Tonight...Lots of clouds were observed in the morning hours south of Orange, while skies were mostly sunny northward. A drier air mass is expected to push from the west later today, around 700-300 mb, but some moisture is expected to survive close to the surface. Some clouds are expected to linger tonight along these areas. In general, a stationary front lingers well south of the region, while high pressure maintains a light onshore flow into the region. The winds are expected to remain from the north- northeast through at least tonight. The local guidance suggests mostly fair-weather prevailing, as the air mass remains dry from 700-300 mb. Chances of shower are low, and if any form, should be focused along the southern counties. Temperatures will cool down to the low and mid- 50s north of Okeechobee, and above 60 west of Okeechobee.

From Previous Discussion... Issued at 248 AM EST Tue Dec 9 2025

Wednesday-Thursday...High pressure weakens Wednesday as a cold front drops into the southeast U.S. The weak front then passes central Florida Thursday before high pressure begins to rebuild from the west. Only a subtle dip in temperatures will be realized with highs falling a few degrees below normal Thursday afternoon. Highs on Wednesday mostly spread the low 70s from Osceola and Brevard northward, increasing into the mid to upper 70s across Okeechobee and the Treasure Coast. By Thursday, highs fall into the upper 60s and near 70 degrees from Orlando northward with temperatures in the low 70s further south. Low temperatures widely spreading the 50s Wednesday morning dip into the upper 40s and low 50s Thursday morning. Can't rule out a stray coastal shower from the Cape southward on Wednesday. Otherwise, conditions remain mostly dry.

Friday-Monday... High pressure further builds across the state Friday, persisting into the weekend. Low pressure moves offshore the Mid Atlantic coast early Sunday morning, dragging the next cold front across central Florida late in the weekend. A much stronger area of high pressure then builds across much of the eastern U.S. on Monday. Dry on Friday with modest rain chances creeping back into the forecast this weekend. Highs near normal late week climb into the mid to upper 70s this weekend before more widely ranging the 70s Monday behind the front. Friday looks to be the coolest morning of the period behind Thursday's front, and interior lows are forecast in the mid to upper 40s. Warmer along the coast and across Martin county with lows in the low to mid 50s. Morning temperatures creep upward through the weekend, reaching the mid to upper 50s across the interior and upper 50s to low 60s along much of the coast and Martin county.

MARINE

Issued at 248 AM EST Tue Dec 9 2025

Seas diminish 3-4 ft nearshore tonight with seas up to 6 ft offshore persisting through late Thursday. Offshore flow develops mid week briefly increasing 15-20 kts early Thursday as a weak cold front passes the waters. Generally favorable boating conditions are then favored Friday and into the weekend. Isolated to scattered showers are forecast across the waters through Wednesday, mostly south of the Cape. A period of dry weather settles into late week.

AVIATION

(00Z TAFs) Issued at 700 PM EST Tue Dec 9 2025

Mainly VFR thru the TAF period with lingering MVFR CIGs, particularly FPR-SUA. While radar shows very light precipitation, have kept out any mention of VCSH as drier air gradually works southward Wed. NNW winds become light (5 kt or less) overnight, then reach 5-10 kt from the WNW after 16z-18z Wed.
