   @Climatologist49 @AlaskaWx That is very interesting! Here in California, the temperature almost always drops with elevation. I guess Alaska is different.

     @AlaskaWx @Climatologist49 Thanks for the sounding profile plot. What are the two lines showing?

     @EricFielding @Climatologist49 Here's the Wednesday afternoon sounding from Fairbanks. Surface temp -30C, which is the lowest temperature in the atmosphere until 504mb (17,700 ft).

     @AlaskaWx @Climatologist49 Thanks for the explanation. I read the temperature at 17 Km as 0 C with the dew point -30 C. The temperature is decreasing with height above about 850 mbars, which is what I expected. The temperature below has that extra cold that Brian mentioned.

     @EricFielding @Climatologist49 This is a Skew-T Log-P plot, so the line to the right is the air temperature and the line to left is the dew point. Labels on the left side are pressure in millibars. Labels on the bottom are °C.
