Precipitation Anomalies

The following table shows, for about 180 long-term stations, how its Jan-Apr 2015 Precipitation stacks up against normal, and where it ranks among that station's history. The unusualness score is based upon the number of standard deviations difference between the 2013 value and the station's average, based on the station's history.

For a visual presentation, click a station's rank for a "Haywood plot" that shows its cumulative value 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. Because of the relatively few days that make up the year-to-date average during January and February, the plots are often noisy during these months.
