Severe thunderstorm watches have been issued for most of the western Great Lakes region, mainly for the threat of strong straight-line winds and marginally severe hail.  Many of these storms are forming along lake breeze fronts and outflow boundaries, with the storms likely congealing into one or more MCSs by this evening.  0-1 and 0-3 km helicity values are under 50 m2/s2 for the entire region, so the tornado threat is almost non-existent.  Tomorrow could be very interesting in Manitoba!  Check out the forecasting thread in the forum for updates.
