| Area Forecast Discussion National Weather Service Melbourne FL 735pm EDT Thu Oct 30 2025 Issued at 204pm EDT Thu Oct 30 2025 Rest of Today-Sunday...This morning's cold front has cleared the area, with cooler and drier conditions observed across east central Florida this afternoon. Breezy conditions continue, with west-northwest winds 15-20 mph and gusts near 25 mph. Winds will begin to slacken this evening, becoming 5-10 mph overnight. Morning low temperatures will be the coolest so far this season, falling into the lower to mid-50s for most of the area, while locations north/west of I-4 and rural portions of Osceola County fall into the upper 40s. High pressure will continue to build into the forecast area into this weekend. Dry conditions will prevail through at least Sunday afternoon, as PWATs (Precipitable Waters) remain near or below 1". North-northwest winds Friday afternoon will be lighter than Thursday, as the pressure gradient relaxes, at 5-10 mph. Winds will then veer onshore into Sunday. Cooler temperatures will persist into Friday, with highs only reaching the lower 70s across east central Florida. This will make for a very fall-like Halloween night, as evening temperatures fall into the 60s and upper 50s. Overnight lows are forecast in the upper 40s to mid-50s. Temperatures will warm slightly to near normal this weekend, with highs in the mid 70s to lower 90s and overnight lows in the 50s to lower 60s. Monday - Thursday Uncertainty continues in the forecast for next week, as models struggle to maintain run to run consistency. What appears most certain is that a trough or low in the mid to upper levels will dig through the Southeast US. Models are having trouble resolving how this feature will be reflected at the surface and, therefore, exactly what the weather pattern will be for the local area. For now, have maintained isolated to scattered showers (20-30%), with a few storms, beginning Sunday night and continuing into Monday and NBM Probability of Precipitation (20% or less) through the extended period. This will need to be monitored as we head into the weekend and models continue to resolve their discrepancies. Temperatures look to remain near normal in the upper 70s to lower 80s. Marine Issued at 204pm EDT Thu Oct 30 2025 Poor to hazardous boating conditions today will begin to improve into tonight, as high pressure builds into the area, causing winds to relax and seas to diminish. Until then, Small Craft Advisories (SCA) remain in effect for all of the local Atlantic waters through 11 PM, due to west-northwest winds 15-25 kts and seas up to 6-8 ft, particularly in the Gulf Stream. SCAs (Small Craft Advisories) will expire from the nearshore waters this evening, but continue for the Gulf Stream into early Friday afternoon, as seas slowly subside. Northwest winds by Friday morning are forecast to be 10-15 kts area-wide and will veer onshore through the weekend. Seas up to 6 ft will persist in the Gulf Stream through Friday afternoon, then become 2-3 ft into Saturday. Greater uncertainty Sunday night into early next week, as models struggle to resolve the evolution a possible low pressure system near the northern Gulf Coast. For now, what is more confident is that rain chances return Sunday night into Monday, with poor to hazardous boating conditions again into mid-week. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...None. AM...Small Craft Advisory until 11pm EDT this evening for AMZ550-552- 555. Small Craft Advisory until 2pm EDT Friday for AMZ570-572-575. |
