The addition of D0 in northern Alabama was based on increasing 30-day deficits, SPEI, soil moisture, and 28-day streamflows. Based on heavy rainfall amounts this past week and lack of support from multiple indicators, a 2-category improvement was justified for parts of southeastern Georgia and northeastern Florida. 28-day streamflows still support extreme drought (D3) along the Nature Coast. More than 2 inches of rainfall this past week resulted in a 1-category improvement to much of the Florida Peninsula and southeastern Georgia. Due to recent heavy rainfall, abnormal dryness (D0) coverage was decreased across southern Alabama and the Florida Panhandle. 28-day average streamflows and CPC’s leaky bucket soil moisture support D1 in this area. A small area of moderate drought (D1) remains in western Virginia which missed out on the heavier amounts. Widespread 2 to 5 inches of rainfall led to a 1-category improvement to much of Virginia and northeastern North Carolina. Despite the widespread rainfall this past week across northern West Virginia, abnormal dryness (D0) continues due to low 28-day average streamflows, CPC’s leaky bucket soil moisture, and NDMC’s objective drought blends. D1 also continues for parts of southeastern New England with lower rainfall amounts this past week. A small area of moderate drought (D1) remains in southern Maryland which received less than 1.5 inches of rainfall. A 2-category improvement (D1 to D-nada) was justified for north-central Maryland, northern New Jersey, southeastern Pennsylvania, and parts of Delaware which received more than 3 inches of rainfall, completely eliminating 60 to 90-day precipitation deficits and 28-day streamflows are near average. Widespread 2 to 6 inches of rainfall resulted in a broad 1-category improvement across the Mid-Atlantic. In contrast to these above-normal temperatures, cooler-than-normal temperatures occurred across the Great Plains, Corn Belt, and much of the East from April 25 to May 1. Little to no precipitation was observed throughout the West where a significant warmup at the end of April resulted in rapid snowmelt, runoff, and flooding along streams and rivers. Late April was mostly dry across the Central to Northern Great Plains and Middle Mississippi Valley. During the final week of April, the Southern Great Plains along with the Lower Mississippi Valley also received widespread precipitation with amounts exceeding 2 inches across southeastern Colorado, northern and eastern Oklahoma, and northeastern Texas. A pair of low pressure systems tracked from the Southeast northward along the East Coast, bringing a swath of widespread precipitation (2 to 4 inches, locally more) to much of the East Coast at the end of April.
