A much-needed round of rainfall is set to arrive across the Delmarva Peninsula late tonight, providing a temporary break from the dry conditions that have persisted for months. A warm front will lift through the region after midnight, bringing light to moderate rain that will continue through much of Friday. While occasional breaks in the precipitation are possible, Friday is expected to be a generally wet day before rain tapers off just before sunrise on Saturday morning.
Rainfall totals will range between 0.5 to 1 inch on average, with localized areas potentially receiving slightly higher amounts. While this rain will help to wash away accumulated road salt and provide some short-term relief, it will do little to alleviate the severe to extreme drought conditions gripping the region. Rainfall deficits remain substantial, with much of Delmarva running nearly a foot below average for the past several months. This system, though beneficial, will barely make a dent in the long-term precipitation shortfall.
Nonetheless, the rain will bring some temporary improvements to soil moisture levels and reduce the immediate fire danger that has accompanied the prolonged dry spell. However, with no significant additional rainfall in the extended forecast, drought conditions are likely to persist into February.
