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.
