Weather Summary

A warm front moved through southern Ontario overnight bringing light snow and a brief period of freezing drizzle over CARE. During the day, low clouds hung around in the relatively warm southwest winds. This boundary shifted back to the south during the evening, bringing colder northwest winds which kicked off some lake effect snow squalls. One of the heaviest snow bands moved right over CARE.

Flight Summary

There was no flight today. There weren't any suitable mid-level clouds present for CLEX and C3VP was beginning to run low on flight hours thanks to the extra non-overpass flights during this IOP.
