Heavy rainfall is expected to impact the Plains and Mid-South regions through Thursday, posing a risk of urban flooding and increased soil saturation. The National Weather Service has issued alerts for Colorado, New Mexico, Kansas, Oklahoma, and parts of the Mid-South, warning of potentially intense downpours. Elevated convection north of a stationary front may produce rainfall rates of up to 2.5 inches per hour, significantly increasing the risk of flash floods, particularly in urban areas with poor drainage.
