West Drought Summary

Most of Montana has been quite wet over both the short- and long-term, but there are pockets of dryness remaining and developing in the northwest portion of the state. Widespread precipitation over much of eastern Idaho, Wyoming, and southern Montana has kept these areas drought free. Tropical moisture came up the Gulf of California and into the Southwest over the weekend, bringing cooler temperatures and widespread precipitation over both Arizona and New Mexico and into central Colorado. No changes were made in Arizona, but the rains allowed from some improvement to the severe and extreme drought over eastern New Mexico as well as some minor improvements in southeast Colorado. Abnormally dry conditions were introduced into northwest Montana, northern Idaho and extreme northeast Washington while moderate drought was introduced into north central Montana.
