Cold valley area is gradually being eroded away, to be replaced by much warmer air sitting just above. This has resulted in wide temperature variation in the Denali Park-Healy area.
At 530pm, Cantwell was +30F. The AWOS at the Train Station in Denali Park was +28F, while the RAWS near the the WAC is +4; these less than half a mile apart very little elevation difference between the RAWS and AWOS. The cold air is still in place in Healy, with Healy -13F and Otto Lake and the RWIS near Antler Creek -10F.
