Overall, it was warmer and drier-than-normal for Washington, D.C. The precipitation story is probably a bigger concern with only about 1/3 of normal falling this past month. We could use a bit more rain here in June as I’m sure most of you have noticed recently.
The National Weather Service publishes nice monthly assessments usually within a week of the close of each month.
