949 FXUS62 KMLB 020542 AFDMLB Area Forecast Discussion National Weather Service Melbourne FL 142 AM EDT Sun Nov 2 2025 ...New KEY MESSAGES, DISCUSSION, MARINE, AVIATION... .KEY MESSAGES... Issued at 142 AM EDT Sun Nov 2 2025 - Mostly dry today with highs closer to normal in the upper 70s to low 80s most locations. - Rain chances up to 20-30 percent forecast tonight and Monday associated with a weak cold front. - An increase in northerly winds early this week will lead to deteriorating boating conditions across the coastal waters. && .DISCUSSION... Issued at 142 AM EDT Sun Nov 2 2025 Today-Monday...Surface high pressure across the Southeast U.S. lift N/NE as a cut-off low embedded within a deep upper trough approaches and eventually moves across Florida Monday. This will lead to the development of weak low pressure off the southeast U.S. coast that will drag a weaker cold front through the region into Monday. The influence of high pressure today will keep winds relatively light around 5-10 mph, generally out of the N/NE. While some moistening of the airmass will occur today, PW values generally remain below an inch through the afternoon, so conditions should remain mostly dry. However, can`t rule out a few showers mainly across the Treasure Coast and approaching NW of I-4 later this afternoon. The approaching robust cut-off low and a continued modest increase in moisture should help induce a better potential for isolated to scattered showers crossing the area tonight into Monday ahead of the passing front. However, rain chances still remain low around 20-30%. Additionally, HREF and global model guidance shows MUCAPE values are basically non-existent over land, so despite the shear and enhanced lift ahead of the trough/low aloft, lightning is not forecast. Highs will be a little closer to normal values in the upper 70s to low 80s today. Max temps then fall to the low to mid 70s from Osceola/Brevard counties northward on Monday as front moves through, with upper 70s to low 80s still forecast across Okeechobee County/Treasure Coast. Lows tonight will range from the mid 50s to low 60s and then again fall into the 50s area wide into Monday night. Tuesday-Saturday...Still some differences in the model guidance in regards to the mid to upper level pattern into next week. Both the GFS/ECMWF have cut-off low being absorbed into the trough as it shifts eastward. However, the GFS has another cut-off low that breaks off from the main trough and lingers across the Gulf as it weakens through the middle of next week. However, at the surface both the GFS/ECMWF show a similar solution of high pressure building into the southeast U.S. Tuesday and shifting eastward and offshore through midweek before another high builds down across the Mid- Atlantic. North to northeast wind speeds remain elevated around 10- 15 mph on Tuesday and then decrease as they veer and remain mostly onshore through the remainder of the period. Mostly dry conditions look to largely prevail, but GFS does indicate some periods of mostly isolated onshore moving showers mid to late week. Temperatures will gradually rise through the work week into early next weekend, from the mid to upper 70s Tuesday into the low 80s mid to late week and potentially low to mid 80s into Saturday. Lows will generally be in the 60s, with some mid to upper 50s continuing northwest of I-4 through Thursday night. && .MARINE... Issued at 142 AM EDT Sun Nov 2 2025 Today-Tonight...Influence of high pressure and weak pressure gradient will continue to produce favorable boating conditions today into tonight. Winds will remain relatively light around 5-10 knots generally out of the N/NE, with seas 2-3 feet. Winds then begin to pick up out of the W/NW tonight, north of Sebastian Inlet to 10-15 knots as weak front begins to approach/move into the waters, with seas lingering around 2-3 feet. It will remain mostly dry today, but can`t rule out some isolated showers developing south of the Cape later into the afternoon. Isolated to scattered shower development will also be possible into tonight. Monday-Thursday...Boating conditions are forecast to deteriorate into early this week as front moves through the area and winds pick up out of the N/NW around 15-20 knots Monday into Monday night. This will build seas up to 5-6 feet offshore by Monday afternoon, and up to 5-7 feet Monday night. A fresh breeze will continue out of the N/NE into Tuesday continuing to build seas to 6-8 feet, but winds are forecast to gradually relax through midweek out of the NE as pressure gradient weakens. Seas will gradually decrease to 4-6 feet Wednesday and 3-4 feet on Thursday. Isolated to scattered showers will continue to be possible mainly into Monday with the passing front, with mostly dry conditions currently forecast thereafter through midweek. && .AVIATION... (06Z TAFs) Issued at 142 AM EDT Sun Nov 2 2025 VFR conditions through the TAF period. Light and variable winds tonight will become E-NE and increase to around 5-7 KT by early afternoon. Model guidance continues to show isolated showers developing and moving across the Treasure Coast Sunday afternoon. So have maintained VCSH starting at 21Z from VRB-SUA. Winds will then become light and variable once again overnight (00Z Monday). Isolated to scattered showers will be possible across all of ECFL Sunday night into Monday morning ahead of a weak cold front that will push through the area during the day on Monday. So have added VCSH starting at 00Z across the north and along the Treasure Coast, and starting at 03Z for TIX/MLB. && .PRELIMINARY POINT TEMPS/POPS...
