Thunderstorms

Radar image from myweather.com continues to show a decent storm cell moving across Ile Perrot from south to north. Steady and much needed rain has fallen over the last half hour, more I believe than we saw the entire month of July at my home.

A weak frontal boundary and a rather warm (30C) and humid day have triggered a few thunderstorms this evening over extreme southwest Quebec. One cell, that had a warning on it that has since expired, is moving into the Dorion/Ile Perrot region at this hour. There are gusty winds, lots of lightning and some decent rain with this storm. It is moving oddly from south to north and will move onto the West Island of Montreal and Laval in the next hour. More showers and storms are possible overnight an into Sunday as the air mass remains moist and unstable.

I grew up in Chateauguay- I now live in Southwester Ontario. People here say the summer storms are violent, even occasional tornadoes and I have witnessed two since living here. However some of the Chateauguay thunderstorms I do remember were quite violent as well. One thing however I noticed of the many years growing up in Chateauguay is that most of the time these storm cells seem to split up and go around- almost as though there is a dome protecting Chateauguay- Mercier to the south, Ville Lasalle to the north would get pounded while it would be sunny in Chateauguay, the storms would split what looked like just west of Lery and pass both north and south reuniting to the east with a shaft of sun shining down on us surrounded by fierce thunder, lightning and black skies- why does this happen??? Is this an air current, topography or some other weather anomaly or just "pure luck" I have heard of "super cells splitting" to create new cells, any answers- email me at markclifford814@gmail.com....interested in weather :) thanks
