Another unusual air flow from the East gives Toronto mild weather

 This is just a slightly larger form of stagnant air.  It gives us the warm days and cold nights of our big September warm times.

We have a classic stagnant bubble, with wind from the East, but this is looping around.

I'll take it.

ps note that the piece of really hot air in the Gulf is gone, and tropical storm Nadine isn't going to grow up.

ps. yeah, they are hot and heavy making up the excuses for the cold winter
