November 13 [Day 53 (Bill Wilson) Once again there was only a small diurnal temperature range from -1C at 0700 to a high of 0C at 1000 and 1100 which slowly dropped to the day's low of -3C at 1645. Ground winds were WSW 0-10 gusting 20 km/h for most of the day, but gusted to 35 km/h in mid-morning, while ridge winds were moderate to strong SW-WSW gusting to 116 km/h in the morning, but only 33-60 km/h in the afternoon. Cloud cover was 80-100% cumulus and stratus for most of the day, thickening after 1500 and very light snow flurries were experienced throughout the day. The eastern ridges were 10-30% (and briefly 50%) draped by cloud after 1100 while the western ridges were 70-90% obscured after mid afternoon. The first migrant raptor was a juvenile Bald Eagle at 0845 and the last was an adult Bald Eagle at 1432 while in between 7 Golden Eagles (5a,1j,1u) were counted. Six of the day's 9 raptors occurred between 1332 and 1432. There was a fair variety of other birds in relatively low numbers including 1 adult Northern Shrike, 1 Golden-crowned Kinglet, 23 Bohemian Waxwings, 1 Red Crossbill and 1 White-winged Crossbill (which perched together), 11 Pine Grosbeaks and 35 Common Redpolls.
