861 FXUS63 KAPX 151030 AFDAPX Area Forecast Discussion National Weather Service Gaylord MI 630 AM EDT Sun Sep 15 2024 .KEY MESSAGES... - Rain-free weather and summer-like warmth persists through next week. && .SHORT TERM /THROUGH TONIGHT/... Issued at 206 AM EDT Sun Sep 15 2024 Pattern Synopsis: Expansive ridging will continue to dominate the pattern at large east of the Rockies through the remainder of the weekend. Further upstream, troughing will dig down the Pacific coast, further reinforcing said ridging into next week. At the surface, weak subsidence/little appreciable forcing aloft will keep high pressure over New England and the Great Lakes through the end of the period. Forecast Details: Rain-free weather and warm temperatures persist -- As previous forecaster discussed, largely a persistence forecast for northern Michigan today and tonight with no appreciable airmass change continuing the recent stretch of warm, dry weather across the region. Forecast highs near 80 along the lakeshores and low/mid 80s for interior areas are in store for this afternoon, with localized readings in the upper 80s possible -- most notably around the TVC area. Calm, clear conditions will once again allow for efficient radiational cooling overnight, dropping temperatures into the 50s for most areas tonight into Monday morning. Typical low-lying cold spots could dip into the upper 40s with patchy fog possible for some locations. && .LONG TERM /MONDAY THROUGH SATURDAY/... Issued at 206 AM EDT Sun Sep 15 2024 Pattern Synopsis/Forecast: Troughing will continue to dig along the Pacific coast into early next week, working to amplify downstream ridging east of the Rockies and keep it in place through the duration of the period. Thus, surface high pressure also largely appears to stay put through next week -- increasing confidence in this extended stretch of summer- like warmth and rain-free weather persisting into next weekend. Highs in the upper 70s and 80s are expected each afternoon with overnight lows ranging from the upper 40s into the 50s. As previous long term forecaster discussed, warm and dry weather spanning this long of a period brings about increasingly concerning fire weather danger over the next 1-2 weeks. Fuels will continue to dry out over the next week with the potential for minimum RHs dropping below 30 percent during the afternoon. && .AVIATION /12Z TAFS THROUGH 12Z MONDAY/... Issued at 630 AM EDT Sun Sep 15 2024 Patchy fog across portions of northern Michigan is expected to dissipate over the next few hours as daytime mixing increases after sunrise. Otherwise, VFR conditions are anticipated through this evening. Light south winds between 5-10 mph will be in place today with the potential for lake breeze formation to push inland from the lakeshores this afternoon -- primarily along the Lake Michigan shoreline. Mostly clear skies and weak/calm winds will once again allow for efficient cooling and additional patchy fog development tonight. && .APX WATCHES/WARNINGS/ADVISORIES... MI...None.
