Issued at 256 PM EST Wed Dec 3 2025 Rest of today-Tonight... The cold front that swept through the area late last night into early this morning is across South Florida this afternoon. Surface high pressure will continue to build across the Florida peninsula into tonight. The low stratus that filtered across the area this morning has long since improved, and will continue to gradually improve through the day, with partly/mostly sunny skies forecast for this afternoon. Locally, winds will be N/NW at 5-10 mph through the day, except along the coast later this afternoon where winds will veer NNE with the east coast sea breeze. Winds overnight will be come light and northerly. Drier air will continue to filter across the area, with global PW values ranging from 0.6-1.08" across east central Florida this afternoon. This will result in no mentionable rain chances through tonight. Temperatures will be more seasonable with afternoon highs in the low to mid 70s across the north, and upper 70s to low 80s. Overnight lows will be much cooler, with lows ranging from upper 40s to low 50s along and north of the I- 4 corridor, and mid to upper 50s everywhere else (except low 60s across the immediate coast of the Treasure Coast. Thursday-Friday... Upper high pressure across the Caribbean will expand across central Florida through the period. An upper level low across the Quebec region on Thursday will shift eastward into the New Brunswick area by Friday and out into the Atlantic. At the surface, high pressure will remain over Florida while it slowly shifts eastward. A low pressure system will develop across the western Gulf on Thursday before shifting eastward across the northern Gulf late Thursday into Friday. This will drag a cold front across the Midwest and Deep South region on Thursday and into north Florida on Friday. Locally, NE to ENE winds at 5-10 mph on Thursday will become light and variable over night before becoming S-SW at 5- 10 mph on Friday. Despite increasing moisture along and ahead of the approaching front, no mentionable rain chances across east central Florida through late week. Temperatures will be on a gradual warming trend, with seasonable to slightly above normal temperatures becoming above normal by Friday. Afternoon highs will be in the low to mid 70s along and north of the I-4 corridor, and upper 70s to low 80s everywhere else on Thursday, with low to mid 80s on Friday. Overnight lows will also gradually warm, with lows ranging from low to mid 50s to low 60s across the interior, and low to mid 60s across the coast on Thursday, and low to mid 60s on Friday. Saturday-Wednesday... Upper high pressure centered over the Caribbean on Saturday will slide southward into early next week as an upper level trough begins to dig across the Midwest and Deep South. A surface cold front across North Florida on Saturday will finally get pushed across east central Florida and into South Florida Sunday into Monday as that trough pushes eastwards towards the eastern US coastline. Surface high pressure will then build down across the Florida peninsula from the Deep South behind the front through mid-week as flow aloft becomes more zonal. Locally, southwest winds around 10 mph or less on Saturday will veer north to northwest Sunday afternoon ahead of the cold front before shifting north to northeast Monday behind the front. North to northeast winds will prevail through early week with winds becoming northeast to east on Wednesday. Moisture will increase through the weekend ahead of the front (forecast PW around 1.75-2.1") before drier air moves in behind the front into early next week with PW values forecast to drop to below 1.0". Rain chances return to the forecast on Saturday as moisture is increasing over the area, with a low to medium (20-50 percent) chance of rain Saturday afternoon, with the highest chances occurring along and north of the I-4 corridor. There is a low threat for lightning storms across the north, mainly north of Sanford in the afternoon. Rain chances continue Sunday, with a medium (50 percent) chance of rain through the day as the cold front approaches the local area. The threat for lightning storms will also continue on Sunday, with a low threat for storms from Brevard to Osceola county northward through late morning, expanding to across all of east central Florida in the afternoon through early evening. Lingering isolated to scattered showers on Monday, mainly from southern Volusia to southern Lake county southward. The highest rain chances (30 percent) on Monday will occur across the Treasure Coast. Drier air will filter down across the area behind the front Monday, with conditions remaining dry through mid-week. Temperatures will remain above normal on Saturday with highs ranging from upper 70s to low 80s across the north, and low to mid 80s across the south. With the higher rain chances on Sunday, temperatures will begin to decrease slightly (while remaining generally above normal though), with afternoon highs in the low to mid 70s across the north, and upper 70s to low 80s across the south. Below normal temperatures will spread across the local area on Monday behind the front and continue through mid week with afternoon highs ranging generally from mid to upper 60s across the north, and upper 60s to low 70s across the south. Overnight lows will generally be in the 60s Saturday night before dropping to low to mid 50s to near 60 degrees along and north of the I-4 corridor and low to mid 60s everywhere else on Sunday night as the front is pushing through. Overnight temperatures continue to drop Monday night through mid week with temperatures ranging from mid to upper 40s to low 50s across the interior, and low to mid 50s along the coast. && .MARINE... Issued at 256 PM EST Wed Dec 3 2025 Today-Sunday... Generally favorable boating conditions through early weekend, with conditions deteriorating Sunday ahead of an approaching front. High pressure will continue to build across the local waters through late week before shifting southward during the weekend. NW/N winds at 7-12 KT today will become N/NE at around 10 KT on Thursday. The pressure gradient begins to tighten late week and into the weekend, with winds veering S/SW and increasing to 10- 15 KT on Friday and Saturday before becoming W/NW on Sunday and increasing to 10-15 KT nearshore and 15-20 KT offshore. Seas 2-4 ft through Saturday, increasing to 2-4ft in the nearshore and 4-6 ft in the offshore on Sunday. Cautionary headlines will likely be needed. && .AVIATION... (18Z TAFs) Issued at 1239 PM EST Wed Dec 3 2025 May see some MVFR cigs linger right along the Treasure Coast from KVRB-KSUA through 19-20Z. Otherwise, VFR conditions are expected the remainder of the afternoon and into tonight as drier air continues to filter in behind the front. This will keep rain chances out of the forecast and allow lower level clouds to continue to diminish. NW winds 5-7 knots will become generally light and variable tonight through Thursday morning. && .PRELIMINARY POINT TEMPS/POPS...
