Sharp Inversion

Here's a plot of the temperature in the lowest 500 meters of the Fairbanks sounding from 3am Wednesday. The surface temperature +7F, while 75 meters up the temperature was above freezing. Not bad. Temperatures around town were quite variable, even on the valley floor. At 9am AST Fairbanks Airport was +12Fwhile fort Wainwright, with an 8 mph downriver breeze, was 28F. At higher elevations temperatures are in the mid 20s to lower 30s. Similarly in the North Pole area, Woodsmoke PWS was +7F and Eielson AFB 27F.
