NWS Gaylord, MI wrote its last area forecast discussion before the first event at Aug 30, 2:16 PM EST, 1 hour 29 minutes earlier.
Area Forecast Discussion National Weather Service Gaylord MI 316 PM EDT TUE AUG 30 2016 .SHORT TERM...(This evening and overnight) Issued at 308 PM EDT Tue Aug 30 2016 Isolated to scattered convection did develop as anticipated this afternoon with the most coverage in the northeastern portion of the forecast area. This activity is associated with an incoming upper level trough and surface cold front which was located across the Mackinac/Chippewa county line at the time of this writing. This front will continue to sag slowly southward through this evening with additional showers and thunderstorms possible out ahead of it. Drier air moving in behind the front (mean 1000-500 mb rh of about 30 percent) will advect in overnight yielding precipitation free conditions along with a bit of a northwest wind and clearing skies. Dewpoints will be slow to fall so it will remain rather muggy through much of the night. Surface high pressure nosing in from northern Manitoba is expected to result in sunshine mixed with some diurnally generated cumulus (due to cooler air aloft) Wednesday. Lows tonight in the middle 50s to lower 60s with highs Wednesday in the cooler lower and middle 70s. .LONG TERM...(Wednesday through Tuesday) Issued at 308 PM EDT Tue Aug 30 2016 Wednesday night through Friday... High impact weather potential: none. Cooler/less humid airmass firmly entrenched across the region early in the period. High pressure that starts the long term period near Hudson Bay will move slowly southward, and will be overhead by late Friday. Airmass will start to moderate by then, as cool/dry advection ceases. 850mb temps will drop as low as 8c over the northern lakes late Wed night into Thu. Delta Ts will range from 7c on Superior, to 12c on northern Huron, to 14c on northern Lake MI. This lines up with a vigorous shortwave dropping south out of Canada, and a corresponding increasing in 850-500mb moisture late Wed night into Thu morning. However, that increase in moisture is not impressive, as the entire system is starved in the department. And the NNE 1000-850mb fetch is generally unfavorable to bring the lakes into play. Will continue to go with a dry forecast, though may have some lake-induced stratocu (especially ne lower MI, and along the immediate nw lower MI coast). Clouds look to be decreasing in the Thu night/Friday timeframe, as the airmass moderates. Min temps Wed night will be mainly near 50 to the mid 50s, as a northerly breeze will stay up in most places. Some interior locales will drip into the 40s. Thu night looks still and thus cooler, with 40s much more common, and the chilly spots will approach 40f. Max temps Thu will be mainly within a few degrees of 70f. On Fri, tack on a few degrees to those expected Thu readings. Thursday night through Monday... Models remain in good agreement through the first half of the extended, before disagreeing on how to handle the start of the new work week. But first, the 500mb pattern shows a trough scooching off the eastern seaboard by weeks end, as a prominent ridge over the central conus edges eastward and troughing stretches from the northern rockies down the west side. High pressure at the surface will dominate the scene through Sunday, with dry weather and abundant sunshine. Above normal daytime temperatures are expected from Saturday on...with overnight lows right around climo. As the aforementioned high pushes east, the next weather maker moves in for an ETA of late Monday/Tuesday. The euro is more bullish on pops, bringing showers and thunderstorms from around mid day on...whereas the GFS seems to capture the process of the front edge/first wave eroding as it moves over the lakes, as often is the case...thus pushing the best chances overnight Monday or Tuesday morning. Now that said...both solutions show a quick moving surface low riding up from the central plains to northern Ontario on Tuesday. My guess is that this will be the trigger for the best chance of showers and thunderstorms for northern Michigan. However, such details 7 days out ought to be taken with a shaker of salt. Not to mention the wild card in the mix. The Atlantic is getting active and any tropical storm type activity near the coast could stall the progression of everything we just discussed. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 136 PM EDT Tue Aug 30 2016 A surface cold front will move across the taf sites this afternoon and evening. There will be isolated to scattered showers with an embedded thunderstorm or two through that time. Winds will shift into the north and northwest behind the front and be a little gusty on Wednesday. Cigs are expected to be largely vfr but could sneak into the mvfr category from time to time. && .MARINE... Issued at 308 PM EDT Tue Aug 30 2016 A surface cold front will continue to sag across the nearshore waters through this evening with isolated to scattered showers and thunderstorms out ahead of it. Winds will shift into the northwest behind the front and will be a little gusty on Wednesday. Isolated small craft advisory winds are possible later tonight into Wednesday but no headlines will be hoisted at this time. High pressure centered over Manitoba will build in later Wednesday and hold into Thursday. && .APX Watches/Warnings/Advisories... MI...NONE. LH...NONE. LM...NONE.
