Year-to-date Temperature Anomalies

The first five months of 2012 were the warmest on record for many locations across the United States. The following table shows, for about 150 long-term stations, how Jan-May 2012 stacks up against normal, and where it ranks among the station's history. In some locations, 2012 temperatures have been so dramatically different that they establish a new "neighborhood" apart from the historical year-to-date temperatures. The unusualness is based upon the number of standard deviations difference between the 2012 value and the station's average, based on the station's history.

To see this, click the rank in the table for a plot that shows the cumulative evolution of the station's year-to-date temperature for each year it has been reporting. As you read from left to right, a particular year's trace represents the average of all previous days during that year. For this reason, these plots are often very noisy early in a period (towards the left), but they provide an outstanding representation of unusualness over the whole of the period.
