Perhaps to check further into the actual unit reporting temperatures
in vicinity of Palmer AK, may show additional sub-units as primary..
This occurs when airport or other official station is also present & worthy.
As a long term resident of Alaska with keen awareness of Wx reports and
also find these 'errors' as actual report centers; yet not necessarily nearest.
South of Anchorage the weather may feature major new seasonal mixes..
from Asia, Arctic Ocean, Bering Sea, north Pacific; old Tropical Typhoons.
The federal NWS AK Region site has great local team to process details.
While they also might be off some miles; as major forecast features shift.
From about 1960, I've seen & heard some odd yet correct forecasts here.
Most AK areas rarely make their own weather; as this region is hyperactive.
