Deep Soil Moisture Well Below Average Across the Eastern United States Explaining Why Drought Conditions Are So Severe This Season
EASTERN UNITED STATES — Deep soil moisture levels measured from the surface down to 79 inches are running well below average across a vast stretch of the eastern United States, revealing the root cause behind why current drought conditions have become so severe. The deficit is so significant that even well established plants with deep root systems are unable to tap into groundwater reserves below the surface, painting a troubling picture of how depleted the ground has become heading into the growing season.
Soil Moisture Deficit Deep Enough to Cut Off Plant Root Access
The most alarming aspect of the current drought is not just surface dryness but the depth at which the moisture deficit extends. With readings down to 79 inches showing well below normal conditions, plants that would normally draw water from deeper soil layers are finding nothing available.
For anyone planting a garden right now, all water needs will have to come entirely from manual watering since the ground itself has nothing left to offer roots reaching downward.
Worst Conditions Concentrated Across Mid-Atlantic and Southeastern Corridor
The soil moisture map shows the most extreme deficits across the mid-Atlantic and southeastern United States, depicted in deep red representing the lowest percentile readings. Large portions of the region sit at or below the 5th to 10th percentile for deep soil moisture, meaning conditions are drier at depth than nearly any comparable period on record.
The drought footprint covers an enormous geographic area with very little relief visible across the affected zones.
Weekend Rain Welcome But Long Road to Recovery Remains
Any rainfall arriving this weekend comes at the best possible time given the severity of the moisture deficit now documented across the region. However, a single weekend rain event will offer only surface relief while the deeper soil layers remain severely depleted.
A sustained period of above normal precipitation will be needed before the deeper moisture deficit begins to recover in any meaningful way across the hardest hit areas. Stay with NapervilleLocal.com for the latest weather updates and local forecast coverage.
