Clear skies overnight allowed valley temperatures to fall to the lowest levels of the autumn thus far. Lows included:
Goldstream Creek: 15F
Woodsmoke PWS: 16F (near North Pole)
Eileson AFB: 18F
Gilmore Creek: 20F near Fox
Fairbanks Airport: 23F
UAF West Ridge: 23F
In the hills this was not the coolest night so far: lows were at or just slightly below freezing. Here on Keystone Ridge, the low was 30F but the heavy frost sure was pretty.
