Current daily precipitation data used in these plots is courtesy of the Climate Prediction Center (W. Higgins and W. Shi). These plots are updated everyday at about 2am (MST), with data through 12 UTC the previous day. NOTE: the climatology for this dataset is only a 11 year average, 1996-2006. Caution should be used in interpretting these plots in mountainous regions.
