More than 4 inches of rain fell across the contiguous United States in May, almost an inch and a half more than normal and the most on record for any single month.
Rainfall totaled 4.36 inches across the nation, according to the National Climatic Data Center's monthly State of the Climate Report.
But that was more than twice the rainfall at Baltimore-Washington International Thurgood Marshall Airport, the point of record in Baltimore. There was 2.1 inches of rain at BWI in May, the driest month there in more than two years.
Drier-than-normal conditions were present across the eastern third of the country. But it wasn't enough to even out excessive rainfall across the western two-thirds.
Colorado, Oklahoma and Texas each set records for precipitation, and for Oklahoma and Texas, it was the wettest month of any month on record.
Baltimore is on its way to a wetter-than-normal June, with nearly 3 and a half inches already at BWI.
