Somewhere along the 21 would be key for deciding in the end. Now the southern portion o fit line looks low enough to possibly hit London or vanish and have my city never see a drop. I wish I didn't leave tomorrow at 4 am to Ottawa to work for ten days

This front moving across michigan and ontario has the makings of a weak derecho or bow echo see a gust front building along and south of lake ontario

[Stormydude]

We had a long period of strong wind gusts (possibly some small branches knocked down in scattered places) and then some heavy rain, with moderate lightning. Looks like another round may go through soon.

There is a Tornado Signature moving WSW along Lake Ontario outside of Toronto
