615 FXUS62 KMLB 050920 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 420 AM EST Wed Feb 5 2025 ...New KEY MESSAGES, DISCUSSION, MARINE... .KEY MESSAGES... Issued at 420 AM EST Wed Feb 5 2025 - Areas of dense fog present along the coast and across portions of the interior early this 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 this week and weekend. && .DISCUSSION... Issued at 420 AM EST Wed Feb 5 2025 Current...Based on surface observations, traffic cameras, and satellite imagery, fog development has been most prominent across the coastal counties this morning, with visibilities down as low as one quarter of a mile in spots. Coverage across the interior has not been quite as impressive, though there is still the potential for fog to develop thanks to the favorable environment. A Dense Fog Advisory remains in effect for Brevard, Orange, Seminole, and coastal Volusia. If driving, be prepared to encounter visibility reductions in some spots. Be sure to slow down, use only low beam headlights, and leave plenty of following distance between vehicles. Visibilities should generally improve late this morning, though stratus may linger into the afternoon hours. Today-Tonight...A weak area of high pressure is forecast to remain in place across east central Florida today, with conditions forecast to remain dry. Light and variable winds persist this morning. As mentioned earlier, lingering stratus will be possible in spots this morning, with guidance indicating that cloud coverage thins out into the afternoon. Once this occurs, temperatures are forecast to warm quickly, with highs reaching the low to mid 80s. This temperature gradient between the peninsula and the local Atlantic waters is expected to trigger the development of a weak sea breeze, with the sea breeze moving inland and causing winds to become easterly around 5 mph. Winds then become southerly and light overnight, with patchy to areas of fog forecast to develop across east central Florida once again. There is less confidence in widespread development based on model disagreement, but current HREF guidance has a 40 to 60 percent chance of visibilities less than one mile south of the Orlando metro. Will continue to monitor and adjust the forecast as needed. Dry into the overnight hours, with overnight lows in the low to mid 60s. Thursday-Tuesday...The weather pattern is forecast to persist through this weekend, with weak high pressure remaining stationed across the western Atlantic. Rain chances through at least Sunday remain below 10 percent. The next best chance for any rain looks to be on Monday as a cold front approaches north Florida and then proceeds to stall into Tuesday. There are rather large discrepancies between global solutions this far out, so stuck with the NBM as a safe middle ground, with only about a 20% chance of rain highlighted across northern portions of east central Florida. Predominantly south winds on Thursday become light and variable on 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, causing winds to become east- southeast as the circulation progresses inland. 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 420 AM EST Wed Feb 5 2025 Weak high pressure remains stationed across the western Atlantic through the remainder of this week and into the weekend, keeping boating conditions generally favorable. Winds are forecast to remain light and variable today, becoming easterly in the afternoon as a weak sea breeze develops and moves inland. Thursday, southerly winds 10 to 15 knots develop, becoming light and variable once again on Friday, and then southerly around 10 knots over the weekend. Seas remain between 2 to 3 feet through the rest of the week into this weekend, with some 4 foot seas possible across the offshore waters. Rain chances remain below 10 percent thanks to the area of high pressure. The main concern for boaters over the next few days will be the development of sea fog early evening through the morning hours. This morning, a Dense Fog Advisory remains in effect through 12 PM today for visibility reductions of one nautical mile or less across the Volusia waters and nearshore Brevard waters. Conditions will likely be slow to improve, with some lingering fog and stratus possible into this afternoon. Visibility reductions are forecast yet again tonight into early Thursday morning. With the current set-up persisting across the waters over the next few days, sea fog will continue to be possible through the end of the week and into the weekend, with the Volusia waters and nearshore Brevard having the best chances for development. && .AVIATION... (06Z TAFs) Issued at 1234 AM EST Wed Feb 5 2025 LIFR/IFR conditions continue to spread across the area as of around midnight. The worst of the conditions continue to be at TIX/MLB, with sub-VFR conditions expected across east central Florida by sunrise. Low CIGs/VIS are forecast to improve after around 15Z, though they could linger at TIX/MLB through 17Z.
