Updates on the Cold

Here are a couple of updates from the past couple days. Temperatures are about as stable as can be with clear skies and light winds here on Keystone Ridge. The low of 33 below is the lowest temperature here since Jan 2, 2009 when the low was also -33F.

The afternoon sounding from Fairbanks shows the warming compared to Friday afternoon is underway above 450 meters AGL and will be progressing down in the next day (note that there may be an encoding error in the surface temperature on the 3pm Saturday sounding). This will result in an increasingly strong valley based inversion. The high this afternoon at the Fairbanks Airport was 39 below.
