Weather Summary

A warm front slowly advanced across southern Ontario during the day. Ottawa stayed cold and clear ahead of the front while extreme southwestern Ontario moderated to near freezing with southerly winds and patchy cloud cover. In between was a band of deep moisture, including cirrus, nimbostratus and low clouds.

Flight Summary

C3VP decided to fly a "weather only" flight targeting the warm front as it passed over CARE. The conditions weren't suitable for CLEX, so we didn't participate.
