The episode as NWS DTX wrote it up.
A weak tornado briefly touched down south of Milan.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Detroit, MI wrote its last area forecast discussion before the first event at Aug 28, 11:46 AM EST, 6 minutes earlier.
Area Forecast Discussion National Weather Service Detroit/Pontiac MI 1246 PM EDT SUN AUG 28 2016 .UPDATE... Convective initiation underway along convergent band of cu that has set early this afternoon along the instability axis. Extremely high dewpoints in the upper 70s along and south of this line are contributing to 0-1km MLCAPE of 1500 to 2000 j/kg despite temperatures only being in the low to mid 80s. Ambient wind field is quite weak, but deep layer shear pushing 30 knots may support lose organization. Latest RAP/HRRR soundings indicate plenty of dry air in the column that could support brief a brief downburst containing a 60 mph gust as storm cores collapse while instability may support hail approaching one inch in diameter. The threat will be confined to the Monroe County, far southeast Wayne county, and the Southeast half of Lenawee County. Gradual supression of the instability axis should push activity south of the MI/Oh border by mid to late aftn. && .PREV DISCUSSION... Issued at 641 AM EDT Sun AUG 28 2016 AVIATION... Fog and low clouds early this morning will lift and dissipate, transitioning to low VFR CU deck this afternoon. An isolated thunderstorm is possible, best chance across southern taf sites, but coverage too low to include in tafs. Drier air will work into southeast Michigan late in the day and this evening, which will help limit fog potential, but would still expect some light MVFR Fog. For DTW... Light southwest winds becoming westerly, mainly below 10 knots during the day. Isolated showers and thunderstorm activity looks to be predominately near the Ohio border this afternoon. //DTW Threshold Probabilities... * Medium for ceiling aob 5000 feet today. * Low for ceiling/visibility below 200 ft or 1/2 sm late tonight. PREV DISCUSSION... Issued at 303 AM EDT Sun AUG 28 2016 DISCUSSION... A corridor of fast low to mid level west-southwest flow has resided across Lower Mi during the overnight period. Moist isentropic ascent along the nose of the low level jet, tied to the entrance region of an upper jet max within the base of the upper trough now rotating across wrn Lake Superior, resulted in the development of a cluster of thunderstorms over central Lower Mi overnight. This localized forcing will continue on a northeast track across Saginaw Bay during the pre dawn hours. The upper trough will continue on an eastward track across Lake Superior/nrn Ontario today. The entrance region of the upper jet will linger over srn Mi throughout the day and will force a narrow region of mid level frontogenesis. This frontal forcing, now extending from srn Lake Mi into cntl Lake Huron, will gradually slide south across the forecast area during the course of the day. Mid level dry air and subsidence will follow in its wake. This forcing will generally provide a slight chance of morning convection across the northern half of the forecast area. The chances being limited substantially be weak available instability. Daytime destabilization will provide a little better chance for some afternoon convection as the forcing slides south of a KPHN to KOWZ line this afternoon. Meanwhile, daytime heating will erode morning fog and low clouds and will support afternoon highs into the 80s. The deepening daytime mixed layer and low-mid level dry air advection will result in a slight drop in sfc dewpoints across the Saginaw Valley early this afternoon, spreading south into Metro Detroit during the evening. Mid level confluent flow and building heights following the departure of the mid level wave to the east of Lake Superior tonight will force sfc high pressure to expand into the area from the west. North-northeast low level flow across Lake Huron into Se Mi will occur in advance of this high. The latest NAM, HRRR, and ARW all suggest marine stratus will have a difficult time eroding today. This moisture will then advect across Se Mi tonight with the onshore flow. Fog and/or low stratus will result and will likely persist through the Mon morning rush hour. Once the low level moisture mixes out lat Mon morning, a warm and dry afternoon can be expected on as the sfc high continues to influence the region. Model trends have been a little slower bringing a sfc cold front into the area from the north next week. The latest model suite do not bring the sfc cold front across Se Mi until Tues night. The front will be driven south by a mid level wave forecast to track from nrn Manitoba into nrn Quebec. Limited forcing and instability along the front as it tracks across the area will support very low chances for convection. The passage of the front will however mark a substantial airmass change. Long wave trough amplification across ern Canada during the latter half of the week will drive much cooler air into the Great Lakes (850mb temps forecast to drop into the single digits by Thursday). Thus cool temps (highs in the 70s and lows in the 50s) can be expected the latter half of the work week. MARINE... Westerly winds today will be predominantly in the 5 to 15 knot range, except across northern lake huron will sustained winds look to be closer to 20 knots. Winds will shift to the north tonight as high pressure continues to build in, allowing for light and variable winds on monday. Modest southwest winds expected on Tuesday ahead of a weak cold front tracking through. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. Lake Huron...NONE. Lake St Clair...NONE.
