Yeah Saturday... I've been keeping an eye on that. At least Heat Advisory level heat, decent CAPE, some fun looking sim radar reflectivity on a few models ("Oh Canada!")... Ultimately, ingredients are in place should there be storms.
That was a decent storm in my neighborhood during the 5pm hour. Had off and on hail for a good 20 minutes w/ gusty winds and torrential rain. The hail looked to be around quarter to half-dollar sized (1"-1.25" in diameter). Some leaves stripped off of trees courtesy of the hail.
