Frosty Morning

It was a chilly morning across interior and northern Alaska this morning, signaling that autumn is now under way.  Some temperatures I noted were:

19F  Atigun Pass SNOTEL
20F  Chandalar Shelf DOT
22F  Bettles Field SNOTEL
22F  Dahl Creek near Kobuk
22F  Goldstream Creek CWOP
23F  Goldstream Creek COOP
24F  Coldfoot SNOTEL
24F  Upper Nome Creek SNOTEL
25F  Tanana ASOS
29F  Keystone Ridge - lowest August temperature in the 19-year history
33F  Fairbanks Intl AP

Many of the higher elevation locations in the hills north of Fairbanks dipped below freezing, so it wasn't just a valley-bottom frost.
