July 8th/9th

Just looking at a system thats heading our way from Michigan, severe potentials aren't too high yet but with the clear swath ahead of the storm, moderate rotating potentials (still forcast less than 2% at the moment) and the temperatures we've been seeing, I wouldn't be surprised if that system intensifies for some late afternoon or evening severe weather. there are a few pop ups ahead of the front aswell that are just starting to organize over western lake huron heading northeast.

The next two days afterwards the forcast potentials creep closer and closer to southern ontario. will they become anything? im still on the fence...one can only hope

[tice23]

more pop ups forming a line down lake huron and heading due east

[tice23]

rapidly developing storm over collingwood, just popped up ten minutes ago, already producing hail signature, no watches or warnings issued yet.

this cell has been showing some signs of rotataion and has intensified in the last 20 minutes with the mesocyclone showing up clearly on doppler, current location and direction is just north of Borden heading SE.

Decent lawn watering here in South Barrie. few rumbles, etc.

I'm watching whats coming across Huron right now. Wonder if it will have enough staying power?

[tice23]

hard to say, i think the cell by stratford still has some potential over the next two hours and the band of t-storms near detroit might have a chance, but beyond that i think the cloud cover is getting too thick and killing the convective potentials as the day goes on. i hope all that rain clears out really early by tommorrow morning

[tice23]

also just north west of sarnia theres a cell with good rotation near the town of croswell. im surprised it hasnt triggered a warning yet for that level of activity

[tice23]

two cells from the previous system have picked up a little, showing minor rotation by king city, and also west of the boyd conservation area
