455 FXUS62 KMLB 200609 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 109 AM EST Thu Nov 20 2025 ...New AVIATION... .KEY MESSAGES... Issued at 145 PM EST Wed Nov 19 2025 - Patchy fog is possible for the next few mornings, and instances of locally dense fog cannot be ruled out - A moderate risk of rip currents remains at area beaches - Dry and warm conditions to continue into next week && .UPDATE... Issued at 630 PM EST Wed Nov 19 2025 Overall, the forecast remains on track across east central Florida. The only adjustment made this evening includes adding in the potential for some locally dense fog across portions of southern Lake county and far western Orange county. Model guidance has consistently been hinting at some locally dense fog within these areas, so decided to add it in with the evening update. && .DISCUSSION... Issued at 145 PM EST Wed Nov 19 2025 Now-Tonight...A fair afternoon is underway with temperatures in the upper 70s to low 80s around lunchtime. Outside of a few cumulus clouds along the Treasure Coast and around Lake Okeechobee, much of the area is experiencing a blue sky day. 5-10 mph onshore winds will turn calm tonight as temperatures reach the mid 50s to mid 60s by early Thursday morning. Patchy fog development is in play overnight, particularly from near the Cape to Lake Kissimmee, including places like Titusville, Melbourne, and as far south as the Treasure Coast. Locally dense fog cannot be ruled out, also, so this is something to keep in mind for the Thursday morning commute. Thursday-Saturday...Little change is ahead for the rest of the week as the H5 ridge expands eastward. High pressure and PW under 1" will keep the stretch of dry weather going through at least Saturday. There could be a few more high clouds in the mix Friday as the profile moistens around 250-300mb. Otherwise, expect mostly clear skies to continue, with daytime temperatures a few degrees above normal (low/mid 80s) and overnight lows in the upper 50s to mid 60s. Patchy fog remains possible each morning in the presence of calm winds and narrowing dew point depressions. Sunday-Next Week...A weakened cold front arrives Sunday with light winds shifting to the north through midday, then onshore with the east coast breeze in the afternoon. Broad mid-level low pressure ejects from the Desert Southwest Monday into Tuesday, but ridging over Florida keeps the more active pattern well north. A few model runs show coastal showers developing by Wednesday, but this is highly uncertain this far out. The anticipation is for mostly dry conditions to persist through at least Tuesday with similar temperatures each day (lows in the 60s, highs in the upper 70s to mid 80s). A front could approach the area mid to late week, though model solutions are muddied as to how far south the front goes before stalling. Regardless, moisture will be on the increase, so we will be watching for any signs of at least low rain chances later in the week and for the upcoming holiday. && .MARINE... Issued at 145 PM EST Wed Nov 19 2025 Good boating conditions are forecast through at least Saturday as high pressure remains in place over the local Atlantic. Light and variable winds turn onshore, increasing to around 10 kt each afternoon with the sea breeze. Winds veer NNW Sunday, then onshore again Sunday afternoon, as a weak front approaches. Seas 1-3 ft. && .AVIATION... (06Z TAFs) Issued at 1241 AM EST Thu Nov 20 2025 Conditions remain favorable for patchy fog to develop between 08Z and 13Z, but chances for VIS reductions to MVFR or lower at any particular ECFL airport are low (less than 20%) based on HREF guidance. 00Z HREF lowered MVFR VIS chances from KTIX-KFPR to around 10%, down 10-30% in the 12Z guidance, but have seen some MIFG develop here so opted to continue 6M BR reduction in those TAFs. 00Z HREF also introduced a 40% chance of MVFR VIS south of KLEE and LAMP guidance periodically indicated MVFR VIS reductions, enough to justify a TEMPO near daybreak. VFR conditions and generally light winds prevail after 13Z at the latest. Hi-res guidance is going hard on fog potential Thursday night into Friday morning, but MOS guidance is much less enthusiastic at this time (a common theme the last couple days). Will need a model cycle or two before confidence increases one way or the other. && .PRELIMINARY POINT TEMPS/POPS...
