Precipitation

The graphics presented here were obtained from NECI's State Trend Charts and depict historical temperature averages for U.S. states since 1895. They are derived from the current U.S. Climate Division Database.

These charts present three color-coded time series. The gray line represents the temperature value. The blue line shows the overall trend in a fashion that smoothes out the year-to-year variability in temperature. The light blue shaded area represents the 95% confidence interval for the trend.
