Year to Date Temperature Anomalies

So far the temperatures in 2013 have run hot and cold both literally and metaphorically. Through August 2nd there have been 214 calendar days for which daily temperature anomalies can be evaluated. The chart below categorizes the daily temperature anomalies for the three main population centers in Alaska by standard deviations from the mean. An expected value, based on the normal distribution, is also shown for each category. What really stands out is how many days both Anchorage and Fairbanks were more than on standard deviation from the mean and how many days all three cities were more than two standard deviations from the mean.

Note: So far this year Fairbanks is 1.4 degrees below normal, Anchorage is 0.6 above normal, and Juneau is 0.4 degrees above normal.
