| Area Forecast Discussion National Weather Service Melbourne FL 137pm EDT Sat Jun 6 2026 Issued at 255am EDT Sat Jun 6 2026 Today - Tonight Ridging in the mid-levels will remain centered across the Florida peninsula and the Gulf today, supporting the surface high centered across the western Atlantic just off the southeastern US coastline. The surface ridge axis will extend towards the Florida-Georgia border, resulting in persistent onshore flow similar to the past few days. Wind speeds of 5 to 10 mph in the morning will be enhanced into this afternoon as the east coast sea breeze develops and moves inland, with speeds increasing to 10 to 15 mph. While dry air near the surface and from 850mb and aloft will act to suppress overall activity, the persistent onshore flow off of the Atlantic waters means that isolated, light sprinkles will be possible not only across the local waters but also along the coast. There is a low chance (20%) for a shower or two to move inland along the Treasure Coast and towards Lake Okeechobee, but confidence in this remains low. Overall, conditions across east central Florida are forecast to remain mostly dry today through tonight. The high pressure at the surface and aloft will support a continued warming trend locally. High temperatures across the interior are forecast to climb into the upper 80s to low 90s. Along the coast, the onshore flow will help keep temperatures in the mid 80s. Tonight, lows will remain seasonable in the low to mid 70s, with some rural locations falling into the upper 60s. Sunday-Monday...Late this weekend and into early next week, a brief omega block is anticipated to develop as two mid-level troughs set up on either side of an elongated ridge extending northward towards the Great Lakes. This will keep the mid-level ridge in place across the Florida peninsula and the Gulf, with the ridge gradually sliding westward on Monday as the omega block pattern moves offshore and breaks down. At the surface, high pressure is forecast to remain situated across the western Atlantic, with the ridge axis extending just north of east central Florida. By Monday, the high is forecast to be on a weakening trend. As it weakens, there is some indication that moisture will lift northward towards east central Florida, which could lead to increasing rain chances across the southern portions of the forecast area. At this time, guidance does remain inconsistent in just how much moisture will return to the area, with the GFS (Global Forecast System) favoring the drier solution. The NBM keeps conditions mostly dry on Sunday outside of some isolated sprinkles, with a 20-25% chance of showers across the Treasure Coast and Okeechobee County on Monday. Rain chances may change on Monday if guidance comes into better agreement. With high pressure remaining in place, temperatures will continue to warm, with some spots across the interior reaching above normal values. Afternoon highs ranging from the upper 80s to low to mid 90s are forecast, with the warmest temperatures focused across the interior. Moderate HeatRisk is forecast to overspread a lot of the populated areas on Monday, with some locations across southern Lake County and western Orange County even forecast to reach a Major HeatRisk. Residents and visitors who are planning on spending extended periods of time outdoors are advised to remain well hydrated and ensure breaks in the shade or an air-conditioned building are taken frequently in order to help avoid heat-related illness. Overnight temperatures will remain near-normal in the low to mid 70s. Tuesday-Friday...The omega block breaks down further into Tuesday, with ridging forecast to slide southward across the east coast towards the Florida peninsula. Remnant energy aloft from the western- most trough of the omega block will also travel southward, prompting a weak cold front to slide south across the Florida peninsula on Tuesday. The front is anticipated to pass with little fanfare, though moisture is forecast to increase significantly compared to this weekend (PWATs (Precipitable Waters) recovering into the 1.5 to 2.0" range). Surface high pressure behind the cold front will slide southward as well, but this is where guidance begins to split on solutions. Eyes remain on the Gulf as to whether a low will develop sometime next week, with the position of the low influencing just how much moisture returns to the Florida peninsula and therefore, what rain and storm chances will look like. The Euro and GFS differ significantly on whether the low will develop or not, which is directly influencing the behavior of the NBM. For now, the NBM guidance continues to favor increasing moisture and rain chances, with a 30-50% chance of rain on Tuesday and Wednesday and a 40-70% from Thursday onward. As guidance comes into better agreement, rain and storm chances will become clearer. Temperatures will remain generally in the upper 80s to low 90s during the afternoon hours, with lows in the low to mid 70s. Marine Issued at 255am EDT Sat Jun 6 2026 Generally favorable boating conditions are forecast across the local Atlantic waters this weekend and into next week as high pressure remains situated across the western Atlantic. The ridge axis will extend just north of the local waters, keeping flow generally out of the east through Thursday. Wind speeds generally remain between 10 to 15 knots, with seas of 2 to 4 feet anticipated across the local Atlantic waters. While dry conditions are forecast through this weekend, light, isolated sprinkles cannot be ruled out across the local waters due to the onshore flow. Towards the middle of next week, rain and storm chances are forecast to increase as moisture returns to the area. NOAA Melbourne FL Office: Watches - Warnings - Advisories FL...None. AM...None. |
