052 FXUS63 KAPX 131854 AFDAPX Area Forecast Discussion National Weather Service Gaylord MI 254 PM EDT Thu Jun 13 2024 .KEY MESSAGES... - Trending considerably warmer and more humid Sunday and beyond. Highs in the upper 80s to mid 90s possible Monday and Tuesday. - Various chances of showers at storms at times Sunday night and into next week. && .SHORT TERM /THROUGH TONIGHT/... Issued at 232 PM EDT Thu Jun 13 2024 Thunderstorms developed across central upper earlier this afternoon and this activity is presently drifting into eastern upper. These storms are expected to move southeast out of that area over the next hour or two. Across northern lower, little to no activity thus far. Do expect isolated activity to develop out ahead of approaching cold front. Still can`t rule out a few strong to severe storms with damaging winds and large hail the main threats. The front moves through this evening with clearing skies and diminishing winds behind it. In addition, it will gradually feel less humid with drier air moving in. Surface high pressure moves over the region Friday yielding mostly sunny skies and comfortable temperatures. Cooler tonight with lows ranging from the mid 40s north to the mid 50s south. Highs Friday ranging from around 70 north to the middle 70s south. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... Issued at 232 PM EDT Thu Jun 13 2024 Pattern Synopsis / Forecast: Troughing regime over northeast North America set to break down as a thermal ridge flexes overhead by the end of the weekend, commencing the return of warmth with a vengeance. As the 500mb thermal ridge anchors itself over the Carolinas next week, this will lead to a quick flow around the periphery of the ridge from WSW to ENE, right over northern Michigan. This flow around the fringes of the ridge will result in the potential for convective waves to pass through the region at times next week, with temperatures in the 80s and possibly well into the 90s for some at various times. Primary Forecast Concerns: Precipitation: High pressure keeps things on the dry side Saturday before a wave cresting the ridge axis passes through the region. This will bring about the potential for showers and storms. Admittedly, some uncertainty regarding this feature`s exact track. This theme continues into next week, with any ejecting convective wave originating from the plains being able to bring about showers and storms amid the warm and potentially unstable airmass overhead. Should be noted that this pattern is somewhat conducive for mesoscale convective systems (MCS) to ride along the ridge into the Great Lakes, which could lead to instances of lines of storms containing strong winds. These systems can vary in position, intensity, and timing with every run of guidance, so any forecast regarding individual thunderstorm complexes will have to be fine tuned perhaps a day or two in advance. Temperatures: A pleasant and somewhat more seasonable day in store for Saturday, with highs largely in the 70s (maybe 80s TVC?). Beyond this, temperatures swell into the 80s Sunday and surge well into the 90s across northern lower and upper 80s in the eastern Yoop at least for Monday and Tuesday. Some uncertainty is cast on how high temperatures will exactly climb owing to potential disruptions of heating from any storms that pass through the region. Should also be noted that dewpoints surging into the 60s and perhaps near 70 will add quite the humid feel to things, with overnight lows largely stalling in the mid 60s to lower 70s for most during this warm period... certainly an uncomfortable feel set to commence, especially for those without home cooling. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 140 PM EDT Thu Jun 13 2024 A cold front will move across the region this afternoon and evening. Isolated to scattered thunderstorms are expected with the front. The best chances for storms appears to be at CIU (early afternoon) and PLN (mid afternoon). There will be lesser chances for storms at APN, TVC and MBL later this afternoon into early this evening. Cigs and vsbys are expected to remain mainly vfr through the taf period except possibly lower in any storms. CIU could see brief MVFR cigs late tonight/early Friday. Southwest winds will be a bit gusty this afternoon, shift into the northwest by this evening then become light tonight. && .APX WATCHES/WARNINGS/ADVISORIES... MI...None.
