But then that arctic air got set up over southern Ontario, and brought frigid air straight down out of the north. As it crossed Lake Huron and Georgian Bay it picked up moisture off the relatively warm water, and turned it into snow at high altitudes. Down came the snow, turning to 'graupel' as it moved through the warm lower air. And we ended up with one of those changeable fall days alternating between dark gray clouds and patches of blue sky, periods of rain and 'graupel' when the clouds were heaviest.
Can you see a few tiny bits of white in the photo above? The warmer lined pants have come out of the closet, the winter coat has been retrieved from the basement, and it's hat and glove weather now.
