NWS Gaylord, MI wrote its last area forecast discussion before the first event at Jun 14, 6:11 PM EST, 19 minutes earlier.
Area Forecast Discussion National Weather Service Gaylord MI 711 PM EDT Wed Jun 14 2017 .UPDATE... Issued at 711 PM EDT Wed Jun 14 2017 The approaching storms from out over Lake Michigan had shown signs of weakening, but additional showers and storms have been developing across NW lower out ahead of an approaching warm front and shortwave. These storms were nearing severe limits, with large hail to 1 inch being the main threat. This was occurring within the greatest instability across the region, with MLCAPES around 1200 j/kg and sfc-6km effective bulk shear around 30 knots. A more unfavorable environment for storms was noted further east in the CWA, with much less instability. As the shortwave continues across nrn Michigan through midnight, instability will increase across NE lower, but strength and areal extent of storms are likely to be less. && .NEAR TERM...(Tonight through Thursday) Issued at 311 PM EDT Wed Jun 14 2017 ...Shower and thunderstorm chances continue... High impact weather potential: Risk for severe thunderstorms later this afternoon into tonight with gusty winds and isolated large hail as the primary threats. Pattern synopsis: Mid level ridge axis crossed northern Michigan earlier today with heights beginning to lower this afternoon continuing into tonight...all hinged to vertically stacked low pressure centered over southwestern Manitoba. Morning/early afternoon elevated slow-moving showers and thunderstorms have gradually progressed eastward showing gradual diminishing with little in the way of any threats at this hour. Stubborn stationary boundary downstate westward through southern Wisconsin has made little northward progress through early afternoon; however, moisture has certainly increased across portions of northern Lower with low- mid 60s dew points west of I-75, aided by slight veering of low level winds (925-850 mb). Initial focus this afternoon-evening revolves around a convectively aided mid level shortwave across IA with ongoing convection into southwest WI, which has the potential to progress northeastward into eastern WI/MI by this evening into tonight. Primary forecast concerns/challenges: Shower and thunderstorm evolution through tonight, along with the risk for severe thunderstorms. Morning showers and thunderstorms across Lake Michigan have gradually progressed inland through early this afternoon, albeit in a significant weakening fashion. Associated cloud cover has limited destabilization across a bulk of northern Michigan, although 18z SPC analysis suggests 500-750 J/kg of MLCAPE has developed across southwestern sections of the forecast area. Latest visible satellite imagery shows partially clearing skies slowly working their way northeast into the same areas...only expected to increase instability west of I-75 through the remainder of the afternoon. Per latest hi-res RAP/HRRR guidance upwards of 1,500 J/kg is suggested across the GTV Bay region diminishing significantly east of I-75. After a lull in precip activity this afternoon (beyond the current diminishing radar returns), coverage and perhaps intensity of storms is expected to increase once again as the aforementioned shortwave across IA/SW WI moves northeastward and the stationary boundary to our south gradually becomes displaced. Currently strengthening convection across southwest and central WI (within the upstream severe t-storm watch #328) will have the potential to impact portions of Lower Michigan as early as this evening with the most likely timeframe for additional thunderstorms between 7 pm-midnight, but in reality, propagation of the ongoing storms and additional convective initiation will be partially tied to cold pool dynamics and is something far from certain at this juncture. Damaging winds will be the primary threat with any thunderstorms, along with an isolated large hail threat despite modest freezing levels around 12- 13 kft. SPC continues to highlight all of northern Michigan in a marginal risk for severe thunderstorms with a greater slight risk scraping Manistee/Benzie counties through tonight. Hi-res guidance suggests precip trends diminish after midnight across the entire forecast area, although scattered showers and a few thunderstorms will remain possible through Thursday afternoon, diminishing from west to east as the system's cold front crosses the region. Mild low temperatures tonight ranging from the upper 50s north to the upper 60s across the southwest. High temps for Thursday from the 70s north to the low-mid 80s south. && .SHORT TERM...(Thursday night through Saturday) Issued at 311 PM EDT Wed Jun 14 2017 ...Becoming warmer/humid/unsettled again to start the weekend... High impact weather potential...few thunderstorms at times. Better chance for storms Sat afternoon. Closed 500mb will weaken, but not quiet open up, as it traverses southern Manitoba and northern Ontario. Associated surface low will eventually minor out in the James Bay area. Post-frontal airmass is not especially dry, so precip chances are not zero in the Thus night- Fri timeframe. But as we head into the weekend, sw low-level flow will again become prevalent, as high pressure along the gulf coast relaxes, and pressures lower in the central plains. Precip chances will be higher Fri night-Sat. Thu night/Friday...the primary cold front will have cleared northern MI by Thu evening. Somewhat deeper moisture will reside in eastern upper MI thru the night, closer to the upper low north of Superior. Will need a chance of showers in parts of eastern upper MI thru the night. A reinforcing shortwave will dig into the western lakes late Thu night, pushing a secondary front into the region. This may kick off some showers in parts of northern lower, especially in the MBL/CAD areas late Thu night, sliding over to near Gladwin Fri morning. As daytime heating goes to work, we should have enough instability and boundaries floating around to sprout a few showers/storms in the afternoon. Best chance for that will be in western Chip/Mack Cos, and in n central and ne lower MI (away from Lake MI). Min temps mid 50s to lower 60s. Max temps upper 70s to mid 80s, cooler along the beaches. Fri night/Saturday...low level warm/moist advection again strengthens from the s and sw. Low level jet isn't terribly potent (increasing toward 30kt), but enough to maintain chance pops most areas Fri night into Sat morning. Coverage will increase Sat afternoon with diurnal heating, and will carry likely pops across a good portion of n central and ne lower MI. Shortwave energy digging into the northern plains will assist this. Amount of instability that we can realize will determine whether we have any sort of svr threat. Min temps upper 50s to lower 60s. Max temps upper 70s to lower 80s. Surface dew points will be creeping into lower and perhaps mid 60s on Saturday, so definitely feeling a little sticky again. .LONG TERM...(Saturday night through Wednesday) Issued at 311 PM EDT Wed Jun 14 2017 While unsettled conditions may bring spotty showers through portions of the extended, the primary concern is with a more robust system moving through the region over the weekend. Current timing is late Saturday/early Sunday. The timing has been fairly consistent over the last couple of runs, but the intensity is quite divergent model to model. Certainly merits watching over the next few cycles. This system will help usher in a cooler, drier airmass going into next week with more near normal temperatures and more comfortable dewpoints. && .AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon) Issued at 224 PM EDT Wed Jun 14 2017 Continued mainly VFR conditions are expected to continue to continue through today under mid level clouds and cu field. Threat for occasional showers and a few thunderstorms to impact the western TAF sites thru mid-afternoon, but by far a better chance for more impactful showers and thunderstorms spreads west to east across the area this evening into the early overnight. Some storms will be capable of producing very gusty winds and heavy rain, along with brief IFR conditions. MVFR strato-cu deck still expected to develop Thursday morning. East to southeast winds, at times gusty today gradually veer south- southwesterly during the day Thursday, but not before LLWS is expected to develop tonight as the low level jet intensifies. && .MARINE... Issued at 311 PM EDT Wed Jun 14 2017 East-southeast winds continue this afternoon through the majority of the overnight hours...strongest across the northern half of the area with small craft conditions expected to continue through early tonight. Of bigger concern continues to be the increasing threat for showers and thunderstorms across all of the western Great Lakes this evening into tonight. Some of these thunderstorms could become capable of producing very gusty winds and perhaps large hail. Winds gradually decrease and turn southwesterly during the day Thursday. && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LH...SMALL CRAFT ADVISORY until 3 AM EDT Thursday for LHZ345>348.
