November 12 [Day 52] (Cliff Hansen) The ridges started clearing after 1000 when the temperature was 0C which rose to the day's high of 1C at 1100 and 1500 and was still 0.5C at the end of the day. Ground winds were S-SW, calm to 5 km/h initially before increasing to 7-15 km/h with a maximum gust of 50 km/h at 1500 after which it was 0-10 km/h gusting 25 km/h for the rest of the day. Ridge winds were moderate to strong SSW-WSW with a maximum gust of 122 km/h at 1500. At 1600 the field sheets were ripped from the clipboard by a wind gust and had to be retrieved from the Kananaskis River. Cloud cover was 100% altostratus, cumulus and altocumulus all day and light snow fell all afternoon. The ridges progressively became enveloped in cloud throughout the day with the west 90% and the east 50% obscured by the end. Not surprisingly, these conditions only yielded one migrant raptor, an unaged Golden Eagle at 1142, and non-raptor species were also scarce.
