| Area Forecast Discussion National Weather Service Melbourne FL 210pm EDT Monday Jun 15 2026 Issued at 202am EDT Monday Jun 15 2026 Today-Tuesday... KMLB radar imagery shows mostly dry weather over east central Florida with a few light isolated showers over the Brevard and Treasure Coast waters. GOES-16 satellite imagery shows mostly clear to partly cloudy skies. Temperatures are currently in the mid 70s to low 80s with dew points in the mid 70s. A similar forecast is expected today with high pressure over the western Atlantic, as well as the eastern Gulf of America and south Florida (~1018mb). Dry weather is forecast in the morning hours before scattered to numerous showers (20-50% west of the Orlando Metro and 50-70% to the east) and lightning storms are expected to develop into the afternoon as west-southwest flow converges with the east coast sea breeze. Guidance shows PWAT (Precipitable Water) values in the 1.9-2.3" range this afternoon, MUCAPE as high as 2,500-4,000 J/kg, and bulk shear between 15-35kts where sea breeze collisions occur. The main hazards will be frequent lightning, heavy rainfall (1-3" in 60-90 minutes with a 1-in-10 chance in excess of 2" up to 4" total), and wind gusts up to 40-50mph. West-southwest winds at 5-10mph with gusts up to 15-20mph are forecast before winds back onshore with the east coast sea breeze in the afternoon, mainly to the east of the Orlando Metro through midweek. Expect a similar forecast on Tuesday with a slight eastward movement of the high over south Florida and the western Atlantic. Above normal (~3-6+ degrees) afternoon highs in the low to mid 90s are forecast each afternoon with heat index values as high as 102-107F. Warm low temperatures in the mid 70s are forecast. A Moderate to Major HeatRisk exists today and Tuesday. A Major HeatRisk affects anyone without adequate cooling and hydration. Remember to stay hydrated and take frequent breaks from the heat! Wednesday-Friday... The western Atlantic ridge is expected to weaken as a major shortwave trough deepens over the western Atlantic. The result for east central Florida is slightly drier conditions as west-southwest flow converges with the east coast sea breeze, mainly from Brevard county northward on Wednesday. Scattered showers (30-60%) and lightning storms are forecast into the afternoon. On Thursday, the east coast sea breeze will push further inland with a slightly stronger east coast sea breeze which will increase the probability of precipitation (20-40%) inland. Rain chances (30-50%) increase areawide on Friday as weak perturbations pivot along the base of an upper level trough over northern Florida. The main hazards each afternoon will be frequent lightning, heavy rainfall (1-3" in 60-90 minutes), and wind gusts up to 40-50mph with the best potential for stronger storms on Friday. Afternoon highs in the low to mid 90s are forecast with lows in the mid to upper 70s and a Moderate to Major HeatRisk. The Weekend... Scattered to numerous showers (50-70%) and lightning storms are forecast each afternoon with a frontal boundary over the Southeastern US and northern Florida. There is the potential for strong storms each afternoon. Afternoon highs in the low to mid 90s are forecast with lows in the mid to upper 70s and a Moderate to Major HeatRisk.possible Marine Issued at 202am EDT Monday Jun 15 2026 Today-Tuesday... Favorable boating conditions are expected. Scattered to numerous generally offshore moving showers (20-70%) and lightning storms are forecast, especially from the Brevard county waters northwards (some of which will have the potential to become strong). West- southwest winds at 10-15kts with gusts to 20kts are expected to back south- southeast into the afternoon. Seas to 2-3ft are forecast. Wednesday-Friday... Favorable boating conditions are expected. Isolated to scattered generally offshore moving showers and lightning storms are forecast on Wednesday (some of which will have the potential to become strong). Drier conditions are forecast Thursday and Friday with isolated showers (20-40%) and lightning storms forecast. West-southwest winds at 10-15kts with gusts to 20kts are expected to back south-southeast into each afternoon. Seas to 2-3ft are forecast.
