For this event, we were well prepared with forecasts being produced by students who had previously worked on the field project every 6 hours (00 UTC, 06 UTC, 12 UTC and 18 UTC). Emilie P., was the forecaster at the time, tipping us off to expect precipitation around 18 UTC according to the 12 UTC RAP and NAM run. Environment Canada on the other hand did not have any precipitation predicted that afternoon. The team here at Kananaskis diligently checked the radar and around 1800 UTC a line began forming around Banff that oriented NNE to SSW. The line lingered there for a while. Meanwhile, here at Barrier Lake there were strong warm winds, suggesting that it was drying out as it moved further West across the mountains, as nothing was appearing past that line on the radar. However, at 2100 UTC something popped up to the West of KES so I headed off to KES to wait it out.
An hour later at 2308 UTC very very light rain was observed over KES. That line of rain lasted an hour, however only ten minutes of rain (moderate intensity) was actually observed. The rest of the hour was mostly light rain to very very light rain. Later in the evening at 0205 UTC about ten minutes of very small snow particles were observed, however temperatures were too warm to take photos.
The site was all packed up by 0300 UTC, once the radar was clear. During the event the temperatures dropped 10 degrees, starting at 15.5 C at 2200 UTC and cooling off to 5.5 C by 0240 UTC.
