From Thursday through Saturday, a developing storm system brings increasing rain coverage across the central U.S., with the heaviest rainfall focused over eastern Colorado, Kansas, and northern Oklahoma by Saturday evening. This system will also produce multiple rounds of moderate to heavy rain, especially across the Central Plains. Light showers will also sweep through the Northeast early in the period, tied to a lingering Nor’easter, while the West stays mostly dry under high pressure. As moisture pools along a stalled front, the setup raises growing concerns for localized flash flooding and sets the stage for a soggy Memorial Day weekend.
