Sustained Temperature Anomalies

Here are plots of temperatures over the past year (through April 17) for Barrow and Fairbanks, courtesy of the Climate Prediction Center.

Of particular interest is the middle plot on each graphic. This is the 31 day running mean, so it smooths out the day to day variation and brings out the longer term patterns. The persistence of warmth at Barrow since last summer, and the mostly below normal temperatures at Fairbanks since December are obvious.
