According to the June 6, 2017, U.S. Drought Monitor, moderate to severe drought covers 7.8% of the contiguous United States, an increase from last week’s 5.3%. Extreme drought was completely eliminated from the lower 48 states for the first time since May 2010. And exceptional drought, the worst category, continued to remain absent for the 20th consecutive week.

A high pressure ridge in the upper-atmosphere began to assert itself over the contiguous United States this U.S. Drought Monitor week. But, upper-level troughs and closed lows continued to move through the jet stream flow.

These upper-level systems and their surface fronts brought cooler- and wetter-than-normal weather to the Southern Plains and Northeast, and above-normal precipitation to the Southeast, improving drought conditions. But, they were weakened as they moved through the upper-level ridge, with warmer- and drier-than-normal weather consequently dominating across the West, Northern and Central Plains, and Midwest. Persistent dryness in the Northern Plains resulted in expansion of drought and abnormal dryness.
