834 FXUS62 KMLB 290600 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 100 AM EST Sat Nov 29 2025 ...New AVIATION... .KEY MESSAGES... Issued at 630 PM EST Fri Nov 28 2025 - Cool again tonight, but not as cold as last night. Turning warmer overnight at the immediate coast where there is a low chance for sprinkles or a brief shower. - At our beaches, a strong southward-flowing longshore current is present; there is a moderate risk of rip currents. Hazardous boating conditions also persist. Rough surf at the beaches will exist on Saturday due to the moderate onshore breezes. - Turning warmer this weekend. Low to medium rain chances anticipated early next week as moisture increases and a front approaches the area. && .UPDATE... Issued at 630 PM EST Fri Nov 28 2025 Temperatures are already dropping in a hurry across the district, into the 50s to low 60s. This drop will be more dramatic in the evening before leveling out overnight. Over the interior, expect lows in the mid 40s to low 50s, coolest northwest of Orlando. At the coast, a sharp inversion in the lowest 1 KFT is forecast to form this evening as onshore winds develop immediately above the ground. This is in response to strong high pressure building over the Mid-Atlantic states. Through the night, the warm/moist onshore layer deepens toward the surface, with guidance showing a classic, tight temperature discontinuity along the Intracoastal. Because of this, our barrier islands should hold in the 60s through the night, especially south of Cape Canaveral. Residents between I-95 and the Intracoastal are likely to see a drop in temps this evening before the start to rise later in the overnight. Suffice to say, once the sun rises tomorrow, temperatures will quickly warm above where they were all day today. With a modest layer of moisture coming onshore at around 3-5 KFT, have added sprinkles and a very small chance for showers, at the coast and mainly south of Cape Canaveral, later on tonight as well. && .DISCUSSION... Issued at 140 PM EST Fri Nov 28 2025 Current-Tonight...Even under mostly sunny skies behind the latest cold front, a chilly day overall as temperatures struggle back into the 60s and with a breezy/gusty northerly wind - it feels even cooler. Fairly stout high pressure continues to build toward the Deep South and mid Atlc states and is partly responsible for the tight pressure gradient (lower pressures southward) allowing for the elevated winds. Gusts to 25 to 30 mph are occurring - typically highest along the coast. Dry air will continue to filter down the peninsula through tonight. Winds at 925 mb veer onshore early tonight and a little more slowly at the surface (along the coast) overnight. As such lows should realize M-U40s north/west of I-4, L50s southward toward Lake Okee, and M-U50s toward the coast, except L60s across barrier islands and immediate Treasure Coast. The strong northerly winds will cause a southward-flowing longshore current within the surf zone, which poses a risk to those entering the ocean. A longshore current can pull swimmers into deeper water and potentially exposing them to dangerous rip currents. In addition to the longshore current, there is also a Moderate risk of rip currents. If heading to area beaches and entering the chilly surf, be sure to always swim near a lifeguard and heed the guidance of local beach safety officials. Sat-Sun...The surface high centered across the mid Atlc states gets nudged seaward Sat night/Sun with the approach of the next low pressure system. Dry conditions persist over land until Sun when moisture begins to pool northward, as we keep a small PoP (20%) across the Treasure Coast counties. An isolated lightning storm cannot be ruled out late aftn Sun. Winds veering ERLY but still 10- 15 mph and gusty on Sat, with the pgrad finally relaxing into Sun, thus lighter wind speeds (7-12 mph) and fewer gusts. Temps begin to trend upward with highs in the L-M70s on Sat and back to U70s to L80s on Sun. Mins Sat overnight/Sun morning in the 50s to near 60F across the interior and L-M60s along the coast, except U60s for immediate St. Lucie and Martin coasts. Mins Sun night/Mon morning in the 60s nearly areawide, save for some U50s in portions of north Lake and NW Volusia counties. A Moderate risk for dangerous rip currents will exist at area beaches on Sat. Also, with the wind flow veering onshore, expect rough surf as well. Mon-Fri...Previous Modified...The next cold front will push towards the Florida peninsula early next week, with low pressure developing across the northwest Gulf and lifting northeastward. Isolated to widely scattered (15-26%) showers will be possible on Mon, with coverage increasing on Tue (20-50% - highest I-4 corridor) as the front moves southward across the area. There is low confidence in storm development at this time, so we continue to keep only mention of showers across the peninsula at this time. Ahead of the front, temperatures are forecast to continue warming, with highs in the U70s to L80s for most, perhaps M80s for portions of St. Lucie and Martin counties on Tue. Overnight lows remain steady in the 60s for Mon/Tue mornings, cooling into the 50s to L60s Wed morning (post-frontal). Towards the middle of next week, the cold front will move south of the area, with high pressure building across the area and drier air filtering in from the north. Mostly dry conditions forecast from Wed-Fri, with afternoon temperatures generally in the 70s and lows in the 50s to L60s. && .MARINE... Issued at 140 PM EST Fri Nov 28 2025 A Small Craft Advisory continues areawide. Hazardous boating conditions continue across all of the local waters thru at least this evening due to gusty northerly winds of 20 kts and seas building to 5-8 ft. Some gusts to 25-30 kts expected. Only minimal improvement in conditions into Sat as both winds/seas are slow to decrease. Poor to Hazardous conditions remain thru Sat, esp over the Gulf Stream where winds/seas will be highest. Northerly winds will begin to veer this evening, overnight, and into Saturday (NE, ENE, E) with the pgrad slowly relaxing further Sat night/Sun. By late Sat or early Sun we are hopeful that all remaining Advisories and/or Cautionary Statements will be dropped. Seas will gradually subside to 3-5 ft early-mid next week. Seas could build back to 6 ft well offshore (north of Sebastian Inlet) Tue-Tue night surrounding the next front. An onshore wind component will continue into Mon evening, then is forecast to veer further to southerly, then of an offshore component Tue-Wed with approach/eventual passage of the next frontal boundary. Rain and lightning storm chances enter the picture again as early as Sun, with highest potential on Tue (pre-frontal). Models continue to speed up the next low pressure system as the cold front is now forecast to move across the waters as early as Tue night, followed by a return to high pressure and dry conditions. && .AVIATION... (06Z TAFs) Issued at 100 AM EST Sat Nov 29 2025 VFR through the TAF period. North winds at most terminals shift northeast to east into late morning. However, winds along the Brevard and Treasure Coast may show a more dramatic shift, starting west or northwest and becoming east by daybreak. Early morning winds around 10 kts or less become gusty by mid to late morning. A few sprinkles cannot be ruled out along the coast, but have excluded any mention of precip in the TAFs. && .FIRE WEATHER... Issued at 140 PM EST Fri Nov 28 2025 Sensitive to near-critical fire weather conditions expected across portions of the interior this afternoon, especially Lake and far western portions of Orange and Osceola counties. Dry air has settled across east central Florida, which will cause minimum RH values to fall below 35% for several hours across these areas. In addition, a tight pressure gradient across the local area will promote northerly winds to reach 15 mph and greater at times with higher gusts likely. The only criteria not being met for Red Flag Warning issuance is the Significant Fire Potential, which continues to remain at a "low" risk for today. Sensitive fire weather conditions across the rest of the interior will be possible with minimum RH values of 35-45%, with lower concern along the coast, though the breezy/gusty northerly winds could create containment concerns should a fire ignite. && .PRELIMINARY POINT TEMPS/POPS...
