791 FXUS63 KAPX 271822 AFDAPX Area Forecast Discussion National Weather Service Gaylord MI 222 PM EDT Fri Jun 27 2025 .KEY MESSAGES... - Scattered showers and possible thunderstorms into this evening. - Additional chances for rain and thunderstorms at times this weekend into early next week. && .SHORT TERM /THROUGH SATURDAY/... Issued at 222 PM EDT Fri Jun 27 2025 Pattern Synopsis: Shortwave troughing will continue to slide across the Great Lakes tonight into Saturday as ridging works in from the west. At the surface, a ~1008mb cyclone currently centered over Lake Superior will trek east-northeast into Ontario tonight, eventually working across Quebec on Saturday. Surface high pressure will temporarily build into the region on the backside of this system after the attendant cold front swings across the area later this evening and tonight. Forecast Details: Light showers have popped up across parts of northern lower Michigan with partial clearing and resultant uptick in instability. This activity will continue to track northeast with time this afternoon. Additional shower/storm development is possible across northwest lower as the aforementioned front swings into the area. A strong storm or two appears unlikely at this time given meager lapse rates resulting in profiles that would work to prevent higher-topped thunderstorms. Any lingering shower/storm activity is expected to dissipate later this evening, leaving a rain-free forecast in place tonight and Saturday. Slightly cooler temperatures are in store for most of the area on Saturday behind the front. West-northwest winds will be in place through the day as temperatures look to warm into the 70s during the afternoon. Highs in the low 80s will be possible for those close to Saginaw Bay. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Issued at 222 PM EDT Fri Jun 27 2025 Pattern Synopsis: Ridging will continue to slide east of the region as troughing punches across the Upper Midwest late this weekend. The associated surface cyclone will trek across James Bay into Quebec Sunday into Monday, with additional pressure falls/weak cyclogenesis along the attendant cold front draped across the Great Lakes. Said troughing looks to move east on Tuesday, placing subsidence over the Great Lakes that will help build surface high pressure across much of the region through the end of the week. Forecast Details: Chances for showers and a few embedded storms return to northern Michigan as activity from west of Lake Michigan may move into the eastern U.P. and parts of northwest lower Michigan late Saturday night/early Sunday. Most of northern lower is expected to stay dry through the afternoon Sunday before more widespread rain and thunder chances move into the Great Lakes beginning Sunday night. Building instability with continued warm, moist advection will bring the potential for a few strong storms late Sunday and Monday, although limited deep-layer shear appears it will help cap higher severe thunderstorm potential at this time. Regardless, rounds of showers and storms are anticipated to start next week before chances taper off into Tuesday and remain low through the middle of the week as aforementioned high pressure builds in. Otherwise, warm temperatures well into the 80s and even low 90s are in store for Sunday before cooling back into the upper 70s/low 80s after the system moves through. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 124 PM EDT Fri Jun 27 2025 A few isolated showers/storms may develop this afternoon, although chances are low that they`ll directly impact any of the terminals. Otherwise, varied CIGs across northern Michigan ranging from LIFR/IFR north to increasing probabilities for VFR at MBL/TVC/APN through the remainder of the daylight hours. Increasing probabilities for at least MVFR CIGs, if not lower, at all terminals tonight before cloud bases rise and scatter out through Saturday morning. Occasionally gusty southwest winds this afternoon veer more westerly tonight while losing most of the gustiness. && .APX WATCHES/WARNINGS/ADVISORIES... MI...None.
