DISCUSSION

Issued at 206 PM EST Mon Dec 8 2025

Tonight-Tuesday...Front near Lake Okeechobee this afternoon will shift farther southward into tonight, with drier/cooler air continuing to gradually build in behind the boundary. Wind speeds will remain somewhat elevated into tonight up to 10-15 mph as surge of northerly flow behind the front continues. Winds then veer slightly to the north-northeast into Tuesday and remain up to 10-15 mph. A few showers may still be possible, mainly near to south of Melbourne through late this afternoon and early evening. Otherwise, it is forecast to remain mostly dry across the area with cloud cover slowly decreasing. Cooler temperatures forecast into tonight, with lows in the 50s for much of the region, except mid to upper 40 northwest of I-4 and low to mid 60s holding on along the southern Treasure Coast. Highs on Tuesday will be below normal, ranging from the mid to upper 60s near to north of Orlando and in the low 70s south.

Wednesday-Friday...High pressure builds down across the region as another front moves into the southeast U.S. Wednesday and eventually across the area early Thursday. High pressure then builds in behind the weak front into late week. No precip is expected with the frontal passage, with dry conditions forecast across central Florida from mid to late week. Highs will remain near seasonable values in the 70s, and overnight lows will be near to slightly below normal, generally between the mid 40s to mid 50s.

Saturday-Sunday...High pressure shifts eastward into the weekend, and model guidance has begun to back off on showing another frontal passage until Sunday night at this time. Temperatures look to remain close to normal into the weekend, with highs continuing in the 70s and lows in the 50s. The ECMWF has some coastal showers, mainly along the Treasure Coast later in the weekend, but GFS remains mostly dry. For now, the forecast leans toward the NBM, which only has a low (20%) chance for showers along the Treasure Coast for Sunday.

MARINE

Issued at 206 PM EST Mon Dec 8 2025

Tonight-Tuesday...Poor to hazardous boating conditions forecast across the waters through tonight and into Tuesday. Frontal boundary near the Lake Okeechobee region this afternoon will continue southward into tonight, with northerly winds across the waters increasing to around 20 knots this evening, and remain elevated through tonight. This will build seas to 6-8 feet. Will expand the SCA to include the entire waters for tonight, and then the SCA will continue across the Gulf Stream waters through Tuesday afternoon as seas up to 7-8 feet linger even though winds out of the N/NE decrease to 10-15 knots.

Wednesday-Saturday...High pressure will build down across the area into midweek, with another front pushing into the southeast United States. Winds will continue to decrease Wednesday, switching to the west-southwest around 5-10 knots, but seas up to 6 feet will linger over the Gulf Stream waters. Winds then become northwest around 10- 15 knots early Thursday morning as front moves through, decreasing to 5-10 knots Thursday afternoon as seas fall to 3-5 feet. Another area of high pressure then builds in behind the front late week and winds diminish to 5-10 knots generally out of the N/NW as seas continue to decrease to 2-3 feet. A little more uncertainty then exists into the weekend, as models have backed off on another frontal passage early in the weekend.
