Where the risk of seeing some Graupel today. Once you are in the green/yellow/red colours blobs, chances are good. #onwx #onstorm

I also pulled out the lightning trigger that I left a fresh Alkaline 9V in only to discover it was dead during the storms last Tuesday. So here I am with some rechargeable 9V batts and no lightning but "stormy wx" approaching. The odds were never good for 🌩️ today. #ONwx #ONstorm

You know, if it wasn't 7 degrees outside, and this was a little taller, it would actually probably technically be a LP supercell... not bad for a walk with the dog.
