Nearly an inch of rain had fallen across the Baltimore region from Tuesday morning through midday Wednesday, helping to slow or reverse a developing drought.
From 5 a.m. Tuesday through noon Wednesday, 0.83 inches of rain had fallen at Baltimore/Washington International Thurgood Marshall Airport, according to the National Weather Service.
Some parts of the region saw more rain than that on Tuesday alone. More than 1 inch was reported in Reisterstown and Norrisville, in northwestern Harford County, with nearly an inch in Sykesville, according to CoCoRaHS, a network of weather spotters.
More heavy rain is forecast Wednesday afternoon and evening. The weather service predicts more than half an inch could fall by about midnight.
About 43 percent of Maryland was in a moderate drought as of Nov. 22, according to the U.S. Drought Monitor. That area stretches across the western shore of the Chesapeake Bay, covering the entire Baltimore metropolitan region and stretching into Western and Southern Maryland.
The precipitation is likely to shrink that area when the drought monitor issues updated maps later on Wednesday.
