Sharp inversion in the Denali Park area

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.
