Decadal average precipitation anomalies (difference between the decade and the 1901-1960 average precipitation) for the Northeast region were plotted as a bar graph. Note: the far right bar contains data for 12 years (2001-2012).

Annual total precipitation amounts were averaged for all gridpoints in the Northeast region. Decadal averages were then calculated. Finally the 1901-1960 average precipitation amount was subtracted from the decadal average amount, and a percentage change in precipitation was calculated.

The duration of this activity was 6 hours.
