Heavy rainfall from scattered thunderstorms is expected across the Southwest, Intermountain West, and Plains. Isolated dry thunderstorms may initiate additional fires across the west. The coastal Carolinas may experience flash floods in the coming days due to repeated thunderstorms.

Overview
A classic early spring weather system brought moderate rain to the region before a band of snow set up primarily over southwest Minnesota.
Precipitation began early Friday morning with a mix of freezing rain, sleet and snow. Later in the afternoon hours, a line of moderate to heavy rain quickly developed along the Missouri River Valley, which spread gradually northeast across the area. Widespread rainfall was reported, with isolated thunderstorms and some sleet mixed in. A strong band of snow developed in southwest Minnesota and adjacent areas late in the evening, producing heavy snow, and even thunder snow in some locations.
Highest snowfall amounts were reported east of the I-29 corridor with snow totals ranging from 4 to around 10 inches. Lincoln, Lyon, Murray and Cottonwood counties in Minnesota received the highest snow totals.
