NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 12, 2:05 AM EST, 50 minutes earlier.
Area Forecast Discussion National Weather Service Gaylord MI 305 AM EDT Mon Jun 12 2017 .NEAR TERM...(Today through Tonight) Issued at 303 AM EDT Mon Jun 12 2017 ...Some thunderstorm threat continues... High Impact Weather Potential: Isolated severe thunderstorms possible across parts of the area? Pattern Synopsis/Forecast: Passing wave racing east across Canada is forcing subtle height falls on northern extent of subtropical ridge axis laying out across the northern Lakes. Convective outflow augmented surface trough/cold front making slow southeast progress across central upper Michigan down into northern Wisconsin, with a more aggressive push of drier air behind secondary and more defined cold front dropping southeast into northern Minnesota. Earlier well organized line of convection to our northwest is slowly falling apart as it continues to push into our area, simply a product of it outrunning better instability and forcing. Much like yesterday, a very challenging convective forecast heading through today and tonight, with little in the way of larger scale forcing to tie convective initiation and upscale growth to. Overhead moisture plume does advance southeast with time, becoming increasingly focused to central and southern Michigan. Lead surface trough/cold front also sags south, with that more aggressive push of drier air behind passage of that secondary cold front later today and tonight. All the above definitely points to better shower and thunderstorm potential targeting southern sections of our area through tonight. Primary forecast concerns/challenges: Shower and thunderstorm evolution through tonight. Addressing what looks to be limited severe weather concerns. Details: Satellite/radar trends and simple pattern recognition definitely support high-res guidance progs of a continuing decay to what is left of overnight showers and storms, resulting in just a few showers dotting the landscape by sunrise. Definitely a low confidence forecast with regards to convective trends for the remainder of the day. Timing of passing surface trough/convective driven cold pool and focus for deeper moisture to drop south sure does not bode well to afternoon showers and storms across much of the area. If anything, simple trends increasingly support best shower and storm development to take place further south than earlier guidance advertised, and starting to wonder if any activity will be found north of M-72 later today. Large scale trigger simply not there to go anything more than just chancy wording, even across southern areas. Gonna take some enhanced low level convergence to get by some lingering capping issues, and that may even be hard to come by given disorganized surface features. That same general idea holds for much of tonight, with the "greatest" focus for wet weather centered across our far southern areas (and perhaps mostly south of our cwa). Will tailor forecast to this less aggressive idea, keeping the area north of M-72 dry through the overnight. As for severe potential: Conditions not nearly as favorable as those observed yesterday. Combination of minimal large scale forcing and a noted decrease in deep layer shear above southward shrinking instability plume should keep any organized severe threat minimal. Still, just enough cape and potential for precip loading cores to keep an isolated severe thunderstorm mention in our latest hazardous weather products, especially south of M-72 per the latest SPC Day One convective outlook. && .SHORT TERM...(Tuesday through Wednesday) Issued at 303 AM EDT Mon Jun 12 2017 ...Slightly cooler with small chances for showers/storms... High Impact Weather Potential...A few thunderstorms possible, mainly south of M-72 on Tuesday. Pattern Synopsis/Forecast...Cutoff upper low over Montana Tuesday morning will lift into central Canada by Wednesday afternoon. This will result in downstream ridging over the Upper Great Lakes becoming more amplified over the period, with the ridge axis crossing northern Michigan by Wednesday afternoon. At the surface, high pressure over Canada will nose into eastern Upper and Tip of the Mitt on Tuesday, ushering in some drier, slightly cooler air behind a weak cold front advancing further downstate. In fact, the higher theta-e air will pool just south of the APX CWA on Tuesday. The front will begin to slowly lift back northeast as a warm front on Wednesday, ushering in a return to slightly better atmospheric moisture. A few weak vort maxes will ripple around the upper ridge periphery across northern Michigan on Tuesday and possibly Wednesday, but overall forcing for some showers and storms looks rather unorganized and not too impressive. Primary Forecast Concerns...Chances for showers/storms will be the main forecast challenge. Drier, cooler air advecting in from the north as well as subsidence from upper ridge will help to suppress any convective activity over eastern Upper and Tip of the Mitt Lower. Instability will be limited to mainly south of M-72, where MUCAPE will generally be less than 1000 J/kg and weak warm air advection will result in some weak capping. There will be synoptic lift from weak passing shortwaves aloft as well as some frontogenesis over northwest Lower, but it does not look to support organized, widespread convection. So, it appears the better moisture, instability, and lift will coincide south of M-72. Will limit chance PoPs to that area on Tuesday and just slight chance PoPs across our south and west Tuesday night into Wednesday, though feel there will be many areas that stay dry. Have pretty much ignored the NAM as it's been suffering from convective feedback issues. && .LONG TERM...(Wednesday night through Sunday) Issued at 303 AM EDT Mon Jun 12 2017 High impact weather potential...Thunderstorms possible at times through Saturday. Wednesday night into Thursday a warm front will lift northeast through the area, placing northern Michigan in the unstable warm sector within a plume of higher theta-e. This will result in the best chance of showers and storms over the long term period, but a cold front sweeping through Thursday evening will suppress rain chances at least briefly for Thursday night. Broad troughing aloft associated with the cutoff low over the Hudson Bay region may allow for some showers and possibly a few storms on Friday over northern Michigan. A piece of shortwave energy dropping out of western Canada will be quickly carried into the Upper Great Lakes on Saturday by a zonal jet stream over the northern states. This, along with a cold front, will provide a better chance of showers and possible storms as better moisture comes into play. Drier, cooler air will arrive behind the front for Sunday, which looks to be the driest day of the period as high pressure builds in from the west. Temperatures will continue to run above normal for most of the period, cooling to near normal by Sunday. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Issued at 1145 PM EDT Sun Jun 11 2017 A cold front will slowly slide thru Northern Michigan tonight into Monday...stalling just south of our area by Monday afternoon. Scattered showers and thunderstorms will impact Northern Lower Michigan overnight thru Monday along this boundary. Conditions will generally remain VFR overnight...but will drop to MVFR for some locations on Monday just behind that boundary. LLWS will continue to impact TVC and MBL overnight just ahead of the front. && .MARINE... Issued at 303 AM EDT Mon Jun 12 2017 After a brief round of somewhat gusty southwest winds early this morning, expect winds to subside substantially through the day as a weak front settles through the region. These light winds are expected to continue right through Tuesday. Band of showers and thunderstorms will continue to rapidly decay, leaving behind just some scattered activity through tonight, with the focus expected across central and southern Lake Michigan. No big severe outbreak expected, but any thunderstorms will be capable of producing brief periods of gusty winds. && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LH...NONE. LM...NONE.
