Area Forecast Discussion National Weather Service Melbourne FL 413am EDT Thu Mar 27 2025 ...New KEY MESSAGES,ARINE,Fire Weather .KEY MESSAGES... Issued at 324am EDT Thu Mar 27 2025 - Sensitive fire weather conditions persist due to low relative humidity, an increasing onshore wind, and dry fuels. - Poor to hazardous boating conditions tonight into early Saturday, as east-southeast winds freshen and seas build, mainly south of Cape Canaveral. - Increasingly unsettled weather pattern this weekend, deeper moisture provides higher chances for showers and lightning storms, especially on Sunday. Issued at 324am EDT Thu Mar 27 2025 Today-Friday...High pressure builds across the western Atlantic off of the Southeast US coast late this week, extending a ridge axis across north Florida. This will lead to onshore flow today and Friday. Winds will be breezy at times today, then increasingly so tomorrow, as the high strengthens. Winds 10-15 mph this afternoon will become 15-20 mph Friday afternoon, with gusts up to 25 mph, particularly along the coast. These winds, combined with dry air an no precipitation, will continue to produce sensitive fire weather conditions (see the Fire Weather section for more details). Onshore flow will help to moderate afternoon temperatures, with upper 70s along the coast and lower 80s inland. Overnight lows in the 60s, with upper 50s in normally cooler, inland spots. This Weekend...The ridge over the Atlantic will drift eastward this weekend, veering winds southeasterly locally. Increased moisture will begin to advect into the area on Saturday, with PWATs (Precipitable Waters) increasing to 1.25-1.5" by the afternoon. A passing upper level shortwave should provide enough forcing to produce isolated to scattered showers and a few storms by Saturday afternoon, mainly south of Orlando. Probability of Precipitation 20-25% increasing to 30-40% area- wide into Saturday night. By Sunday, deeper moisture (PWATs (Precipitable Waters) 1.3-1.6") and a passing mid/upper level trough are forecast to combine to produce the highest Probability of Precipitation our area has seen in some time. Have capped Probability of Precipitation around 60% due to some discrepancies in the models about where the highest coverage of showers will be, though it does appear to be across the southern portion of the CWA. Regardless, scattered to numerous showers appear likely, especially during the afternoon, with isolated lightning storms. Will need to monitor the threat for a few strong wind gusts due to dry air aloft. Scattered showers and a few storms will linger into Sunday night, especially along the coast from Cape Canaveral southward. Southeasterly winds, breezy at times, will persist through this weekend. High temperatures creep upward through the period, with lower 80s along the coast and mid-80s inland. Above normal overnight lows in the mid to even upper 60s are forecast. Monday - Thursday A low pressure system moving across the northern US will drag a cold front towards the area into early next week. Models are in decent agreement about this feature stalling as it moves into Florida, though disagree on exactly where (GFS (Global Forecast System) being the farther southward solution). Nonetheless, the front is not forecast to clear southward of the CWA (County Warning Area) at this time, with isolated to scattered Probability of Precipitation continuing through early next week amid lingering moisture. Temperatures will continue to rise, reaching the mid to upper 80s, while overnight lows linger in the mid to upper 60s. Marine Issued at 324am EDT Thu Mar 27 2025 Boating conditions will deteriorate late this afternoon into tonight, mainly south of Cape Canaveral, as high pressure strengthens over the western Atlantic. Easterly winds 10-15kts this morning will increase to 15-20kts overnight and through Friday. Seas 4-6ft, with up to 7ft well offshore from around Sebastian Inlet southward. Small Craft Advisories have been issued for the waters south of the Cape beginning this evening and late tonight, persisting through early Saturday morning. Rain chances return this weekend, particularly Sunday, with a few lightning storms possible. Winds become southeast on Saturday and remain up to 15-20kts into Saturday night, before decreasing to 10-15kts Sunday. Seas 4-6ft persist through the weekend. Boating conditions will begin to improve early next week, as winds become southerly and seas diminish. Fire Weather Issued at 324am EDT Thu Mar 27 2025 Very sensitive fire weather today, with near-Red Flag conditions for portions of the interior this afternoon. Dry air will lead to min RH between 30-40% west of I-95, while onshore flow keeps coastal areas between 40-50%. While winds are forecast to be below criteria (10-14 mph) over the interior, there may be a period this afternoon where winds peak, while min RH is at its lowest, creating the near-Red Flag conditions. Winds around 15 mph are forecast near the coast this afternoon, though min RH is expected to remain above critical thresholds. High pressure and dry air linger over the peninsula Friday, with min RH 35-45% inland and 45-55% along the coast. Fire weather conditions will remain sensitive, as onshore winds increase to 10-15 mph, with gusts to around 20-25 mph. Fire weather conditions will begin to improve this weekend, as higher moisture (and precipitation) moves into the area. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...None.
