Issued at 135 AM EDT Fri Oct 17 2025 Broad upper ridging extends northward from the northern gulf coast states to the Great Lakes region. The surface reflection is a 1022 mb high pressure center located southeast of the Great Lakes. The upper ridge and surface high will slowly move east-southeastward and will be located along the eastern seaboard by Saturday morning. This pattern will keep a predominant east-northeast wind flow, partly cloudy skies and dry conditions over the Florida peninsula through Saturday. By Sunday morning, the upper ridge and surface high has shifted farther southeastward off the Carolina coastline between the Bahamas and Bermuda. Farther to the north, upper level troughing and an area of low pressure moves through the Great Lakes region with a cold front extending southward through the Ohio River Valley and into the north central gulf. The trailing edge of this weak cold front will approach the area from the northwest on Sunday. This will bring a shift in the winds to the southeast and southwest and also bring a slight uptick in moisture over the region. Rain chances remain on the low side, but can`t rule out a stray shower as the front moves through on Sunday into early Monday. The front pushes south and east of Florida and dissipates on Monday as high pressure builds back in over the southeast U.S. with pleasant weather expected for most of next week. Near seasonal temperatures expected through the period with daytime highs in the mid to upper 80s and overnight lows in the upper 50s to low 70s. && .AVIATION... (06Z TAFS) Issued at 135 AM EDT Fri Oct 17 2025 VFR, rain-free conditions and east-northeast winds less than 12 knots expected through the period. && .MARINE... Issued at 135 AM EDT Fri Oct 17 2025 High pressure north of the area will produce rain-free conditions and prevailing east-northeast winds around 10-15 knots through the day, with some brief periods of increasing winds to Cautionary level overnight tonight and again on Saturday night. The only chance of any showers will come on Sunday as a weak front moves across the eastern gulf waters. High pressure then builds back into the area for the first half of next week with pleasant weather expected. && .FIRE WEATHER... Issued at 135 AM EDT Fri Oct 17 2025 Pleasant weather expected for most of the period with only a slight chance of a shower on Sunday. No fire weather hazards are expected as sufficient moisture will keep minimum afternoon relative humidity values above critical levels. && .PRELIMINARY POINT TEMPS/POPS...
