Updated at 232 PM CDT Fri Oct 10 2025 - Below normal temps and lower humidity expected through this weekend. - Hazardous marine conditions for all of the coastal waters through Saturday morning. && .SHORT TERM... (This evening through Saturday night) Issued at 232 PM CDT Fri Oct 10 2025 An upper level ridge encompasses much of the center of the country with the axis extending from south Texas to North Dakota...just east of the Rockies. A deep upper low is just now entering the Pacific NW. To the east of the ridge are 2 upper lows, one weaker one centered over Georgia and deeper one near the Great Lakes. The CWA is right on the eastern periphery of that ridge envelope but moreso under general troughing to the east of it. The current setup will maintain fall like temps and lower humidity across the region throughout this weekend. Drier airmass is not just at the surface. Model PW guidance shows column moisture content to be around 0.5- 0.75" all weekend. Thus, no appreciable land based rain chances locally. && .LONG TERM... (Sunday through Thursday night) Issued at 232 PM CDT Fri Oct 10 2025 Going into next week, we start to lose those cooler temps. Both upper lows situated to the east will shift into the western Atlantic. This will allow for the upper ridge axis centered between the Rockies and the Mississippi River Valley to move eastward, right over the CWA by mid week. In response to those increasing 500mb heights, temps will moderate around 3 to 5 degrees. That puts highs into the mid to maybe upper 80s. This overarching pattern will carry through most of the week. By Friday-ish...may finally start to see that ridge weaken. If it does, won`t be surprised to see chances for light rain to return. && .AVIATION... (18Z TAFS) Issued at 232 PM CDT Fri Oct 10 2025 VFR conditions will dominate the period. There are currently some lower clouds right at the MVFR/VFR threshold but those will lift in time before dissipating later this aftn. && .MARINE... Issued at 232 PM CDT Fri Oct 10 2025 Persistent north-northeast winds of 15 to 25 knots and rough seas ranging from 3 to 5 feet in the tidal lakes and sounds to 5 to 8 feet in the open Gulf waters will be the rule through Saturday. Although could meteorologically justify replacing SCY with SCS in the tidal lakes right now, makes more sense from a messaging perspective to keep SCY out during lull until nocturnal winds increase there. Overall though, these conditions are in response to a low off the coast of Florida and a high centered over the Southern Plains. These rough conditions will keep a small craft advisory in place for all of the waters through Saturday. Sunday will see the high over Texas become more centered over the region. As this occurs, winds will quickly drop to around 10 knots and turn more variable. These lighter winds and gradually improving seas will persist through Monday. A weak front will slip through the waters on Tuesday, and a more persistent northerly wind of 10 to 15 knots will take hold behind the front for both Tuesday and Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
