National Drought Status

It was another dry week out West. The very wet December helped, but more precipitation is needed. Drought in the Southern Plains continues to worsen. According to the U.S. Drought Monitor, Oklahoma has an area of Exceptional Drought (D4) for the first time since 2018. As of January 18, 2022, 46% of the U.S. and 55% of the lower 48 states are in drought.
