Looks like a pretty decent risk of waterspouts across the Eastern / Southern Great Lakes Wednesday evening/overnight.

The 0-3 km dry lapse rate is approaching almost 9C/km with a fair bit of low level MUCAPE. I've attached a few forecast soundings from the 18Z WRF-NAM just as an example. I'm not a fan of that particular model run because it lacks most of the good data needed for a solid initialization but it paints the picture well enough. 

Anyway it looks pretty good for waterspouts even with the relatively high winds (they tend to be more stringy in higher winds). The sfc-850 delta-t is 13C or more and the fetch is well alined for Huron/GB to allow saturating parcels and lowering the LCL's. LFC-LCL is fcst at \~300M AGL but will likely be lower (usually by about 50-100M from experience).

Interestingly the simulated IR product shows some convective plumes with tops of -40C & the HRDPS/HRRR has some lightning showing up in some of the products. I think WRF-NAM does too but I did not look in detail. Obv makes sense.

Should also note only 13 kt shear between the sfc-3km so not much divergence which is what you want, otherwise the shear tears the convergent bands apart.

Also should not there is decent PVA (positive vorticity advection) and a minor mid-level jet just above the parcel equilibrium level. So that could help with further ventilation and potentially increase UVV's.
