Weather Summary

The aircraft was down due to routine maintenance and the weather cooperated nicely. Yesterday's weak system moved on and took all of its clouds with it. Some patchy cirrus arrived later in the afternoon ahead of the next system, but it was mostly clear skies across southern Ontario.
