UPDATE

Issued at 956 AM EST Mon Dec 8 2025

Frontal boundary near the Lake Okeechobee region will continue to push southward through today, with drier air gradually filtering in behind. However, will still see some lingering isolated to scattered showers across the area this morning, with this activity gradually diminishing from north to south through the afternoon and into the evening. Bumped up rain chances a tad across the north where some light showers continue, with PoPs around 30% across Brevard/Osceola counties northward, with 40-50% continuing across Okeechobee County and the Treasure Coast. Isolated storms may also still be possible, mainly across the southern Treasure Coast where some limited instability will still exist through this afternoon. Skies look to remain cloudy to mostly cloudy for much of the day, with highs in the upper 60s/low 70s from Orlando area north and low to mid 70s south (except upper 70s across Martin County).

DISCUSSION

Issued at 244 AM EST Mon Dec 8 2025

Current-Today... A band of organized showers continues to spread south and east of Lake Okeechobee early this morning with more isolated to scattered activity persisting further north. Isolated to scattered showers will continue to clear from north to south throughout the day as a cold front pushes into south Florida. Despite clearing showers, cloudy skies look to persist. A temperature gradient will be in place today as northerly winds develop behind the front. Areas from Brevard and Osceola counties northward should see highs mostly in the low 70s, although a few spots of northern Volusia could touch the upper 60s. Across Okeechobee and the Treasure Coast, highs more widely spread the mid 70s to low 80s. Temperatures overnight mostly cool into the low to mid 50s with areas north and west of I-4 falling into the mid to upper 40s.

Tuesday-Thursday... High pressure builds along the U.S. Atlantic coast Tuesday, stretching across the southeast and into Florida. The area of high pressure weakens locally on Wednesday as a cold front moves into the eastern U.S. The front then decays into early Thursday as it pushes further south. Some low level moisture lingers along the Treasure Coast and near Lake Okeechobee early in the period, keeping some cloud cover around. Otherwise, the moisture profile remains too dry to support any mentionable rain chances through mid week. Tuesday will be the coolest day with highs in the mid to upper 60s near and north of the Orlando metro with mostly low 70s south. Afternoon highs warm to range the low to mid 70s on Wednesday but reach the upper 70s near Lake Okeechobee and across Martin county. Temperatures then cool a touch on Thursday becoming near normal areawide. Low temperatures mostly continue in the low to mid 50s through Wednesday morning with low to mid 40s far north and west of I-4. Cooler Thursday morning, generally ranging the mid 40s to low 50s.

Friday-Sunday... Surface high pressure is reinforced into Friday. The next cold front looks to approach or pass central Florida Saturday before a large area of high pressure builds across the eastern U.S. late this weekend. Dry conditions are maintained through the extended forecast period. High temperatures hold steady near seasonal values, mostly in the low to mid 70s. However, far south near Lake Okeechobee and across Martin county, highs again touch the upper 70s. Lows on Friday spread the upper 40s and low 50s, gradually warming into early next week.

MARINE

Issued at 244 AM EST Mon Dec 8 2025

Scattered to numerous showers and isolated storms will clear from north to south today as a cold front passes south of the waters. Poor to hazardous boating conditions build behind the front as northerly winds increase to 15-20 kts this afternoon, further increasing to 20-25 kts across nearshore Volusia and portions of the Gulf Stream waters. In response, seas build to 6-8 ft in the Gulf Stream late this afternoon and overnight. Small Craft Advisories go into effect at 4 PM today for nearshore Volusia and all legs of the local offshore waters. Winds diminish Tuesday as high pressure builds, and seas subside to 5-6 ft offshore Tuesday night before becoming widely 4-5 ft Wednesday night. Dry conditions settle into mid to late week behind the front.

AVIATION

(12Z TAFs) Issued at 617 AM EST Mon Dec 8 2025

Greater than normal uncertainty this TAF cycle, as models continue to struggle to resolve CIGs near and behind the weak cold front sagging through the area. IFR CIGs ongoing along the Treasure Coast look to persist through 16Z, with MVFR reductions remaining possible for more northern terminals through at least 14Z. Clearing is expected as the front moves south of east central Florida into this afternoon and tonight from north to south. LEE/DAB are forecast to be the first to clear to VFR. However, reductions may linger through much of the day today.

VCSH is also ongoing prior to sunrise this morning. CAMs continue to suggest a quicker exit for precipitation, so have diminishing SH this morning, except for the Treasure Coast and MLB, which could see chances linger into early afternoon. A few thunderstorms cannot be ruled out south of MLB, but SH appears more likely than TS. Northerly winds prevail today around 8-10 kts and are expected to persist into tonight.
