Driving up the 404 on Saturday the sky was fascinating to the west.
There was a heavy rain storm and you could see the water coming and receding and coming and receding. The clouds were flat and it was a deluge. When it rained on you, you could barely see in front of you to drive yet it would only last a few moments then would be clear until the next downpour hit. The land to the west around Aurora and Newmarket is flat with great visibility for miles so rain storms are interesting to watch.
