<\/a>Surface analysis 21Z Fri May 10 2013<\/p><\/div>
\n
<\/a>The setup for storms was driven by a low scooting just north of Lake Erie and Ontario, the supercells in Southcentral and Southeastern Ontario formed along the warm front where a marine \/ lake breeze boundary interacted with the surface warm front and trigger storms<\/div><\/div><\/div>
<\/a>
<\/a>A weak elevated supercell in a low energy but moderate shear environment approaches Milton<\/div><\/div><\/div>
<\/a>
<\/a>The storm is now passing through Milton, you can see mid level clouds flowing into the storm from the Southeast (image looking west). It also presents a bit of a vaulted type structure with the usual lateral tilt of the updraft. Slight clearing between the "hail" region of the core and the heavier rain is visible just to the right of center.\n\nThe biggest problem with this storm if any is the fact that it remained elevated with limited boundary layer interaction and hence produce virtually nothing as far as wind at the surface.<\/div><\/div><\/div>
