The forecast of this event was quite tricky. Stephen was in charge to watch the weather evolution and model forecast 1000 and 1200 UTC and Ida between 1200 and 1400 UTC. At 1500 UTC, Ida and Emilie B. were on the site to take weather observation. Mainly rain was observed during that event at KES.
In particular, from 1500 to 1730 UTC, the precipitation changed from no rain, drizzle, and light rain. There were also mainly light southerly winds, but some short periods of moderate-strength winds.
At 1730 UTC, the rain intensified. A weather balloon was launched Ida and Emilie B. at 1820 UTC. The parsivel was connected at 1800 UTC.

At 1900 UTC, Julie and Emilie B. went to a car ride to Fortress mountain with a Kestrel to find the snow-rain boundary and record weather conditions. The Kestrel was attached to a ski poll and hold outside the car window. A rain-snow transition was noted when going up and down the mountain. Unfortunately, the Kestrel didn't work properly and the data maybe not be very useful. Nevertheless, going to Fortress mountain seems to be a go alternative to the ski-sonde to study the rain-snow transition because it is easier to stop while driving to observe precipitation types. A set of measurements was collected along Fortress Mountain at around 2100 UTC with 2 Kestrels. We have confidence that this method will be very successful!
During this time, Paul and Emilie P. arrived from Montréal (QC). They met Ida et Stephen at the trailer for a knowledge transfer (balloon launch training, snow photos, parsivel and other equipments).
