Frost on the Pumpkin

Clear skies and a cool airmass allowed temperatures to fall below freezing in many low-lying areas around Fairbanks early Sunday morning.  Along with a nice aurora display overnight, the signs of autumn are quickly increasing in Fairbanks-land, even if autumn colors are not much in evident.  For places that did fall to or below freezing, this is within a week of the average date of first freeze.







Some low temperatures include:
Goldstream Creek: 23F
Woodsmoke: 26F (near North Pole)
Eielson AFB: 27F
Two Rivers: 28F
UAF West Ridge: 29F
Fort Wainwright: 32F
Fairbanks Airport: 34F


In the hills temperatures mostly remained above freezing, and a breeze most of the night kept frost from forming at ground level, at least here at Keystone Ridge:

Fox CRN: 33F
Caribou Peak: 33F
Wickersham Dome: 34F
Cleary Summit: 34F
Keystone Ridge 36F
Nenana Hills: 38F

A few low temperatures in the teens were observed in the Upper Yukon Valley, including 19F at Chena Hot Springs and 16F at the Beaver Creek RAWS (west of Birch Creek village).
