The water resources and supplies outlook is "fair" for northern areas in the Mid-Atlantic region but "poor" for southern areas where long-term drought persists.
As summer arrives, scattered showers and thunderstorms can be expected from time to time. In general, this type of rainfall can be hit or miss. Over the past 2 or 3 months, precipitation has generally been running below to much below average across most of the Middle Atlantic region. This persistent dryness has led to increasing areas of drought across southern and eastern portions of the Mid-Atlantic. Severe drought conditions now exist across south-central to southeastern PA, central to southern NJ, northern DE, eastern MD, and into portions of central to western VA. In addition, an expanding area of extreme drought conditions now extends from far southern NJ into the central to southern Delmarva peninsula and westward into central and eastern VA. Future precipitation outlooks indicate that near to slightly above normal precipitation is expected over the next couple of weeks.
