Light to moderate snow will continue into Saturday over the Great Lakes, Central Appalachians, and Northeast. This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >
Overview
On the afternoon of Tuesday, June13th, a warm and very humid airmass had set up across eastern South Dakota and western Minnesota in advance of a cold front. During the mid afternoon hours storms rapidly developed over central and eastern South Dakota, between Pierre and Aberdeen. These storms quickly strengthened and produced large hail, damaging winds, and eventually tornadoes across the region. The storms evolved into mainly a wind and tornado event around 7pm CDT. Widespread wind damage occurred across northeastern South Dakota and into west central MN as the storms formed a line and moved northeast. Storms quickly exited through Traverse and Big Stone Counties by 10 pm CDT. Several tornadoes were reported to have briefly touched down, causing EF-0 and EF-1 damage.
