| Area Forecast Discussion National Weather Service Melbourne FL 733am EDT Wednesday Oct 29 2025 Issued at 344am EDT Wednesday Oct 29 2025 Today - Tonight Very dry air with PWATs (Precipitable Waters) less than 1" continues to filter in from the north as weak high pressure shifts over Florida from the Gulf. A deep and energetic trough diving down the Central US and into the Southeast will push a reinforcing cold front quickly across the area tonight. With virtually no moisture recovery ahead of the front the only moisture available for any rain chances are limited to a narrow band in the low-levels right along the frontal boundary. Therefore, dry conditions expected through the daytime hours, then a low (around 20%) chance of brief showers with the frontal passage overnight. The environment looks to be well capped, and chances for lightning are effectively zero. However, given how quickly the line will be moving through any showers than manage to form could be gusty. Light northerly winds this morning shift southwesterly at 5-10 mph in the afternoon, then northwesterly around 10 mph tonight behind the front. Afternoon highs near to slightly below normal in the U70s-L80s. There is a High risk of life-threatening rip currents at the beaches due to the arrival of long period swell. Entering the surf is not advised. Thursday-Friday...Starting off cool Thursday morning behind the overnight frontal passage, with morning lows in the M50s-M60s, possibly in the L50s in the usually cooler northern spots. Could still be a few showers along the Treasure Coast in the morning but these will quickly push offshore. High pressure and even drier air then builds over the Southeast behind the front. Westerly winds increase to around 15 mph with gusts to 25 mph Thursday afternoon behind the front, which might be able to bring some shallow showers whipped up over the Gulf into the interior portions of East Central Florida (rain chances currently less than 20%), but otherwise dry conditions. Winds become more gentle from the north to northwest Friday. Afternoon highs Thursday decrease to the L-M70s, with a chilly Friday morning expected as morning lows get down in the L50-U40s thanks to a slug of cooler air. Afternoon highs Friday only get up to the L70s (possibly some U60s), with evening temperatures forecast to drop into the 60s after 5 PM, and into the 50s after 8 PM, making for the most Halloween feeling Halloween we've seen in a few years. Saturday-Tuesday...While mid-upper level troughing is forecast to be maintained over the eastern US through the weekend and early next week, models have been inconsistent with the evolution of lobes of upper-level energy moving through the pattern. Pretty good agreement a mid-level low diving through the Central US will stall over the southern US, but whether it becomes cutoff or not has changed model to model and run to run. This morning's 00Z GFS and ECM run both bring the feature to the North Gulf coast early next week, but the GFS (Global Forecast System) aggressively kicks the system eastward Tuesday, while the ECM keeps it in our neighborhood an additional day. And this is technically better agreement than the 18Z runs, where the ECM orphaned the system in the western Gulf while the GFS tracked across the north Gulf states. This impacts the evolution of an associated surface low over the Southeast, and locally how much rain we may get. The sooner and closer to the Southeast seaboard the low develops the more likely we'll have lower (if any) rain chances. However, there is potential for this system to lift moisture associated with the departed Tropical Cyclone Melissa into the area if it were to develop further west, later, and slower. Given at least some solutions call for rainfall but also the high degree of uncertainty, went with a 20% chance in the official forecast for Monday and Tuesday to mention the potential, and less than 20% the rest of the period. Temperatures recover a bit, but forecast to remain slightly below normal. Marine Issued at 344am EDT Wednesday Oct 29 2025 Weak high pressure briefly builds into the local Atlantic waters today. A reinforcing cold front pushing through tonight followed by deeper high pressure Thursday will cause winds and seas to increase again. Winds and seas settle going towards the weekend as the high pressure center moves closer to Florida and the local waters, with better boating conditions expected by the weekend. Seas begin to build in the Gulf Stream again today as swell from low pressure system associated with the previous front arrives, reaching 5-7 ft north of the Cape late this morning, and south of the Cape later this evening. Winds generally light and squirrelly today ahead of the approaching front, becoming northwest 15-20 kts behind the front tonight and Thursday, shifting more westerly Thursday afternoon. Seas peak 5-8 ft Thursday afternoon. Winds settle to 5-15 kts through the rest of the week and weekend as the center of the high moves closer, gradually veering from northwesterly Friday to easterly Sunday. Seas subside to 4-7 ft Friday, and 2-4 ft Saturday and Sunday. A few showers are possible along the front tonight, otherwise generally dry conditions.
