Mid Atlantic Drought Update

As noted over the weekend, recent rains just barely prevented a February-March dryness record from being set in Washington, but the developing drought has barely been dented. The latest weekly Drought Monitor, issued today, shows a slight decrease of Moderate Drought from 32% to 27% in Virginia. Maryland, however, remains at 52%.

With the 0.18" of rain which started off April yesterday, the year-to-date total of 5.18" at National Airport is only 54% of average. At this point, more than 2.27" of precipitation will need to fall the rest of April in order to avoid breaking the record low February-April total of 4.77" set in 1947. Average precipitation for April is 2.77".
