The episode as NWS MKX wrote it up.
A line of thunderstorms brought straight line wind damage to areas north of Madison during the evening hours. A weak upper air disturbance and approaching cold front had triggered the line of storms.

Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 346 PM CDT FRI JUN 10 2016 .TONIGHT AND SATURDAY...Forecast Confidence...Medium A line of thunderstorms continues to develop ahead of an approaching front in northwest Wisconsin. This will be the main feature of concern this evening, as these storms are expected to move southeast toward the forecast area. The first issue is timing of the line, as models are not in very good agreement at this point. The HRRR seems to have the best handle and is also the fastest of the mesoscale models. Latest radar trends suggest even the HRRR might be a little slow with the progression of this convective event. Have thus timed pops toward the faster model solutions. The other concern is how far southeast the line will propagate this evening. There is a general diminishing trend per most models as the line drops through the forecast area. There is thus higher confidence in storms across the north. The latest experimental HRRR brings storms all the way through, which might not be a bad solution given the current placement/speed of the line per the various model solutions. SPC is maintaining a Slight Risk for severe storms across most of the forecast area for this evening. After the storms move through this evening and early tonight, it should turn dry for the remainder of the night and into Saturday morning. Models are suggesting convective development across mainly the southern half of the forecast area tomorrow afternoon in the vicinity of the slow moving frontal boundary. Plenty of instability tomorrow to go along with marginal 0-6 km bulk shear of 20-25 knots. SPC has a Slight Risk for severe storms across roughly the southern half of the forecast area tomorrow. Temps tonight will remain mild, around 70 most places. Not much change in thinking with temps for tomorrow. Looks hot and humid, with highs into the low 90s. Dewpoints in the upper 60s to around 70 will result in heat index values pushing 100. With borderline advisory values and the potential for afternoon storms, opted to hold off on an advisory for now. .SATURDAY NIGHT AND SUNDAY...FORECAST CONFIDENCE HIGH Colder air dropping in behind deepening northeastern U.S. 500 mb trough pushes a back-door cold front south down Lake Michigan and northern Wisconsin Saturday afternoon, and moves the front through southern Wisconsin Saturday night. Some differing model timing of the front into srn WI leads to leaving some slight chance PoPs in for Saturday evening. Front stalls to the southwest and begins to lift back to the northeast as a warm front. Surface boundary does not lift across the CWA but 850 mb warm air advection triggers a band of light precipitation in the consensus solution over the far northwest Sunday morning. Southeast winds will keep the northeastern third of the forecast area cool with highs in the upper 60s to lower 70s, and mid 60s along the lake. The southwest two-thirds will warm into the mid to upper 70s. .SUNDAY NIGHT AND MONDAY...FORECAST CONFIDENCE MEDIUM Precipitation chances rise as a short wave trough flattens amplified 500 mb ridge as it tracks across the western Great Lakes region with the associated surface low from western MN into srn WI/nrn IL by 00Z Tuesday. Model surface dew points may be a bit too moist but enough instability with low to mid 80 high temperatures for thunderstorms. .LONG TERM...MONDAY NIGHT THROUGH FRIDAY...FORECAST CONFIDENCE MEDIUM An unsettled period as deep southwest U.S. 500 mb low opens up and lifts toward region Monday night and Tuesday, then closes off over South Dakota/Nebraska Wednesday and drifts across WI/IL Thursday, stalling over nrn MO/central IL Friday. While there will be some dry periods, uncertain timing leads to chance PoPs Tuesday through Thursday night before low finally drifts far enough south to have Friday and Friday night dry. Temperatures will hover around normal levels for this time of year. && .AVIATION/00Z TAFS/... It should be dry through the late afternoon hours, with storms then likely moving into the northwest this evening. There remains a question of how far southeast these storms will make it, so will have to continue to sort through latest model data as it comes in. There is a chance some of these storms could be severe, with damaging winds and large hail the primary threats. There will be another chance for storms Saturday afternoon and evening, particularly across the southern half of the forecast area. Should see mainly VFR through Saturday, other than lower visibilities in moderate/heavy rainfall. && .MARINE... Storms are likely this evening, with a chance again tomorrow afternoon. Some of the storms could be severe, with damaging winds and large hail the primary threats. Breezy northeast winds may build waves to around 3 to 5 feet Saturday night. A small craft advisory may be needed for this period. && .MKX Watches/Warnings/Advisories... WI...None. LM...None. && TONIGHT/Saturday AND AVIATION/MARINE...DDV Saturday NIGHT THROUGH Friday...REM
