August cool-downs are a common feature here in the North. The highest summer sun was at the solstice two months ago, and autumn has already begun in northern Canada. 

Around here, August weather is often warm and sometimes humid. But brief cool spells are increasingly common this time of year compared to a few weeks ago.  A burst of cool weather in August can bring on feelings of fall. But frost in August is rare. Note: not impossible. It was 34 degrees in Fargo Moorhead on Aug. 20, 2004, and there was scattered frost on the ground that morning.

 Other lights frosts occurred Aug. 13, 1964 (33 degrees) and Aug. 27, 1982 (33 degrees).   The last actual 32-degree reading in August was way back in 1888. 

The average first frost here is Sept. 30, which is about a week later than it was 20-30 years ago. But in any given year, an unusually early frost is always a possibility.
