Projected Palmer Hydrological Drought Index

The NOAA National Weather Service's Climate Prediction Center produces official monthly and seasonal temperature and precipitation outlook products. This information was converted into projected monthly temperature and precipitation values for future months, then the projected values were used to compute projected future PHDI values. "Hot/Cold" and "Wet/Dry" represent the 10th/90th and 90th/10th percentiles of the temperature and precipitation outlook, respectively. "Normal Conditions" accounts for the 50th percentile for both elements.
