In fact, 3 sites had record-dry Mays and another 15 sites ranked the month among their top 16 driest Mays. With many sites also seeing below-normal precipitation in March and April, the spring season ended on the dry side of normal for 28 sites. The continued dryness led to moderate drought being introduced in parts of the region by late May.
