...Very Hazardous Marine Conditions Continue Tonight... ...Cold Front Passes Overnight with Cooling Early Monday... Current - Tonight
West to SW gradient winds have temporarily diminished with nightfall. The environment remains pre-frontal at this hour with the approaching cold front expected to surge south into the area beginning around midnight, then south of the area during the pre-dawn hours. Winds are expected to increase to breezy with the frontal psg before diminishing again around sunrise. cloudiness will remain in place with LL clouds remaining scattered to ocnl broken through the time of psg of the cold front early Monday.

Lows drop to the L-M40s north of I-4 and U40s to L50s south of Orlando. Combined with wind speeds around 10 mph, wind chill readings could drop to the U30s across Volusia and northern Lake counties for a brief period early Monday morning.

Previous Extended Forecast Discussion Slightly Modified... Mon/Monday Night...The Gale over the Mid Atlantic waters will continue to lift N/NE away from the area but breezy W/NW flow will persist beginning late morning into afternoon. Despite partly-mostly sunny skies, max temps will hold in the lower 60s north of Orlando and upper 60s across Okeechobee/Treasure Coast. High pressure will build toward the area Monday night allowing winds to decrease. The high will not be directly overhead Monday night, rather to the NW near AL/GA/FL border so a light N/NW wind flow should exist.

Although winds are not expected to be calm, patchy frost will be possible over normally colder and wind protected locations north of Orlando as min temps dip into the mid 30s by Tuesday morning. Min temps in the upper 30s to mid 40s elsewhere. With the dropoff in winds across the area, wind chill values will not be a significant factor.

Tonight...PAssing front will keep gradient winds near Gale gusts into overnight, especially well offshore. Winds will slowly veer westerly overnight and taper off slowly toward daybreak. A Small Craft Advisory introduction will likely be needed after the Gale Warning expires during Mon.

Extended Previous Marine Forecast Discussion... Mon/Monday Night...Westerly pressure gradient slowly relaxes as deep low pressure lifts NE away from the area. A Small Craft Advisory (SCA) will be necessary to replace the Gale warning esp over the offshore waters with 20-25 knots. Will transition to a Caution headline nearshore as winds fall below 20 knots during the day. Seas starting out 6-9 ft offshore and 4-6 ft nearshore will subside below 4 ft close to the coast in the aftn.

Fire Weather
Mon-Wed...Much colder/drier conditions return with patchy frost possible Tue/Wednesday mornings over normally colder rural portions of the interior. Min RH values Monday afternoon will dip below 40 percent N/W of I- 4 and 40-45 percent elsewhere, then 30-38 percent across the interior on Tuesday with 45-50 percent near the coast. Dispersion values will be Very Good Monday with westerly surface and transport winds but Fair to Poor Tuesday as winds become light North.
