Two Seasons

Updated: Oct 24, 2022

The risk for strong to severe thunderstorm development remains in the forecast for later this afternoon and into the evening hours across the east with snow chances in the west.

A powerful storm system will push warm air into eastern, South Dakota with highs reaching the 70s and 80s but much cooler air behind the system with highs only reaching the 50s in the west today.

Later this afternoon and into the evening hours, there is a risk of severe thunderstorms mainly along and east of the James River Valley with the best risk from Brookings to Sioux Falls towards Sioux City and points east into the southwest, Minnesota, and northwest Iowa. There remains a lot of uncertainty with the development of these thunderstorms, but if storms do develop, these could quickly become severe with the main threat will be large hail and damaging winds. An isolated tornado cannot be ruled out.

Behind the system, Winter Weather Advisories are in effect for the Black Hills and into northwest, South Dakota as the first accumulating snow will affect the area.

Snowfall amounts by Monday evening will be the highest in the Black Hills where three to six inches are possible with some isolated higher amounts. Outside the Black Hills about an inch or two of snow is expected for Harding and Butte Counties.
