Rain, Thunder, and Snow End Extended Warm Spell - March 10, 2021

Overview

A long stretch of above normal temperatures, even record breaking, came to an abrupt end on March 10th as showers and thunderstorms lifted northward. The first true Spring thunderstorms brought needed rain to the area, along with very small hail.

As the morning moved on, colder air caused this precipitation to turn to snow across portions of South Central through northeastern areas of South Dakota. Total snowfall ranged from a dusting to as much as 7 inches of snow.

Colder air arriving during the evening led to flash freezing on area roads, leading to challenging driving conditions the morning after the snow ended.
