543 FXUS62 KMLB 052312 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 612 PM EST Wed Feb 5 2025 ...New AVIATION... .KEY MESSAGES... Issued at 256 PM EST Wed Feb 5 2025 - Patchy fog that could become locally dense, reducing visibility to less than a mile, possible again tonight into Thursday morning. - Potential for dense fog will continue each night and early morning through late week. - Temperatures will remain warmer than normal, with mostly dry conditions through the week and weekend. && .PREVIOUS DISCUSSION... Issued at 256 PM EST Wed Feb 5 2025 Rest of Today-Tonight...Dry and quiet conditions the rest of the day, then another round of Fickle-Fog expected across much of East Central Florida tonight into Thursday morning. A few factors have become less favorable for dense fog development across the eastern half of the peninsula tonight, as high pressure over Florida shifts eastward a bit. First, light southeasterly winds winds veer southerly through the night, resulting in an offshore component along the coast, making it harder for sea fog to develop over the Atlantic waters and move onshore. Next, 925mb winds come alive a little, expected to increase to around 10 kts over the area and helping to promote some mixing. Last, coupled with the slightly elevated winds above the surface, model soundings show a weaker surface inversion. That said, conditions do still remain favorable for some fog thanks to residual moisture, light winds, and weak high pressure. Sea fog in the Gulf will be moving across the peninsula towards East Central Florida tonight, doing battle with less favorable environment over here towards the early. Models are a mixed bag, not really instilling confidence in any particular area or timing. Thus, the official forecast broadly calls for patchy fog across the entire area, with locally dense fog reducing visibility to less than a mile possible. If you encounter dense fog on the roads, be sure to slow down, leave plenty of following distance between vehicles, and use your low- beam headlights. Conditions are forecast to improve by late morning. Otherwise, very warm with forecast temperatures 5-10 degrees above normal. Afternoon highs inland forecast to reach the L-M80s, and M70s-L80s along the coast. Pretty uniform overnight lows forecast, mostly very near dewpoint temperatures in the L60s. Thursday-Tuesday...(Modified Previous Discussion) The weather pattern is forecast to persist through this weekend, with the weak tail of high pressure over the tropical North Atlantic extending to Florida in a suspiciously summer-like setup. Rain chances through at least Sunday remain below 10 percent at this time, but can`t rule out some isolated showers worthy of an increase to 20 percent the day of, especially down south Thursday and Friday as daily sea breezes form and residual moisture from the last front clings to the area. A little better agreement in the global models for next week, which have all shifted the next potential front and its moisture further north. If this trend holds, then mostly dry conditions are on tap for next week. Predominantly south winds on Thursday become light and variable Friday, before becoming southerly once again into the weekend. During the afternoons, a weak sea breeze may develop as a result of the temperature gradient between land and the very cool shelf waters, causing winds to become east-southeast as the circulation progresses inland. A few showers along the sea breeze can`t be ruled out. Highs remain above normal in the upper 70s to mid 80s, with lows in the upper 50s to mid 60s. Fog development will continue to be possible each evening into the early morning hours, with visibility reductions of a mile or less possible in some spots. Be sure to monitor the forecast if planning on driving through the area during the overnight hours, and always use safe driving techniques. && .MARINE... Issued at 256 PM EST Wed Feb 5 2025 Rest of Today-Tonight...The last small patch of sea fog in the Brevard nearshore waters has finally cleared, with quiet conditions across the local Atlantic waters. The afternoon east coast sea breeze has developed, shifting winds near the coast onshore at around 10 kts. Tonight, winds will surge a bit to 10-15 kts as they shift back to the south. Mainly dry conditions, but a couple showers can`t be ruled out. Development of sea fog will be possible again tonight, but as winds increase and become more offshore, chances for fog reaching the coast decrease. Highest chances for fog in the Brevard and Volusia nearshore waters. Thursday-Sunday...Generally favorable boating conditions in a suspiciously summer-like pattern. The center of high pressure over the eastern seaboard is pushed out into the open Atlantic by a low pressure system swinging through southern Canada, but the tail of the ridge axis is forecast to remain over central Florida. With a loose pressure gradient and warm conditions, light south to southwest winds will allow a daily sea breeze circulation to develop, shifting winds near the coast to southeasterly while increasing to around 10 kts in the afternoons. Mostly dry conditions, but isolated showers developing along convergence lines and possibly even sea breeze will be possible. Lightning is currently not forecast. Seas 2-3 ft, occasionally up to 4 ft well offshore in the Gulf Stream. && .AVIATION... (00Z TAFs) Issued at 612 PM EST Wed Feb 5 2025 Kept a VFR forecast for the TAF period at all terminals. Guidance is showing much lower coverage of fog tonight, perhaps due to light S/SE winds off the surface. Will monitor and AMD with TEMPOs as needed. Light SE or VRB winds overnight, becoming SSW 5-12 KT on Thursday except SE 5-12 KT at the coast from MLB to SUA in the afternoon. && .PRELIMINARY POINT TEMPS/POPS...
