Looks like my wishes for storms is coming true. Nice little line setting up to the west of us right now

sorry, didn't see your post until after I just posted. Keeping track of these ones. One looked like it was over 50,000.
Presently securing all of the kids toys and lawn furniture.

im just getting hit by the first bits on the north side of it in midland. just got really dark, apparently some of these cells are producing good size hail too. especially that cell down near fergus.

We didn't get as intense of a storm here. I live in SW Barrie and other than rumbling thunder and some good downpours, nothing else. Maybe later on today?

Over 40 poles are reported to have come down this afternoon. Yes, that was a strong storm, but could it be that the shape/age of these poles was a factor? Latest report now on the 9th Line Essa, wires down.

When I was watching that cell from the Buffalo nexrad site I looked at the radial velocity and at 0.5 and 1.45 deg elevation I thought I saw about 15 minutes worth of mild rotation around the center of that system. however as the storm passed over, the system (IMO) looked like it started to create a bow echo which could be signs of a downburst. I'm trying to track down the images now, hopefully I can find them...I believe the weather was occurring around 1:50pm

here is the radar at the time with my estimates of what was going on...
