.KEY MESSAGES... Issued at 243pm EST Tuesday Nov 18 2025

- Patchy morning fog and a moderate risk of life-threatening rip currents are our notable hazards this week.

- Temperatures continue to nudge above normal as high pressure stays in control.

- Outdoor plans will be greeted with plenty of sunshine. Most locales will remain rain-free for at least the next week.

Current - Tonight
A thin layer of low-level moisture has produced a deck of scattered cumulus clouds along the Treasure Coast and near Okeechobee. CAMs suggest this moisture could be enough to initiate isolated to scattered showers across the Treasure Coast waters. However, a weak sea breeze has developed, and its subsidence should limit most of this activity from moving too far inland. Outside of an occasional shower brushing the immediate Treasure Coast, most of east central Florida is expected to remain dry through the remainder of the day.

Looking towards tonight, conditions become favorable for another round of patchy fog. Localized visibilities of less than one mile will be possible with any fog that develops. If encountering fog on roadways late tonight or early Wednesday morning, slow down, use low-beam headlights, and leave plenty of distance ahead of you. Low temperatures remain seasonal, mostly in the upper 50s and low 60s.

Wednesday-Thursday... Weak low pressure moves offshore the mid- Atlantic coast Wednesday. The attached surface boundary sinks into portions of the southeastern U.S., but high pressure in place locally will keep it north of Florida. Conditions remain generally favorable for patchy fog development across much of east central Florida again Thursday morning. Otherwise, dry conditions persist through the period, and there are no mentionable rain chances. Temperatures climb only a few degrees above normal each afternoon, reaching the low 80s. Low temperatures are forecast to range the mid to upper 50s across the interior with upper 50s and low 60s along the coast.

Friday-Monday... High pressure gets reinforced locally as surface ridging builds over the western Atlantic late this week. The ridge then flattens this weekend as a cold front approaches from the west- northwest. A limited moisture column keeps confidence low for any rain chances associated with the front, and dry conditions are forecast to persist. High temperatures hold steady, mostly in the low to mid 80s. Low temperatures ranging the mid to upper 50s across the interior and upper 50s to low 60s along the coast warm a few degrees into early next week.

High pressure moves offshore the eastern seaboard into tonight, becoming reinforced by a second area of high pressure moving offshore late week. Mostly dry conditions are forecast outside of a few showers this afternoon and evening. Light and variable winds generally remain less than 10 kts through this week. Seas building 3- 4 ft across the Gulf Stream subside Wednesday, becoming widely 1-2 ft by Friday.

Fire Weather
Issued at 243pm EST Tuesday Nov 18 2025

modified previous... Over the next couple of days, seasonably deep mixing (4+ KFT) should tap into some drier air aloft over northern portions of east central Florida. Away from the coast and along the I-4 corridor, RH minima are forecast to range from 40-45% Wednesday and Thursday afternoon. Afternoon breezes becoming NE less than 10 mph. Light to calm winds and excellent RH recovery are forecast each night, so smoke from any fires will have the potential to mix with patchy fog.

Although sensitive across the interior through mid week, RH values are expected to remain above elevated or critical thresholds in all areas.
