Further south, areas of severe thunderstorms and heavy rain are possible from the southern Plains into the Ohio Valley. A Pacific storm will move into the Southwest Monday. Read More >

Overview

Mother Nature provided her own firework show this 4th of July for some, and unfortunately, severe weather as well. A few storms across southern North Dakota merged and intensified as they drifted southward from the early evening to past nightfall across/near the James River Valley. Significant damage resulted from straight-line wind gusts of 80+ mph, as well as an EF-2 tornado near Wetonka. Heavy rain, especially in Hand County, also led to flooding issues. 

Additional rounds of strong to severe thunderstorms developed the following day, on July 5th, mainly across and west of the James River Valley. Wind gusts of 70+ mph were associated with a complex of storms across Jones, Lyman and Buffalo Counties during the early evening. Numerous storms then developed from northern Brown to Walworth Counties, beginning around 7pm. Several funnel clouds were spotted with this activity, particularly around the Long Lake and Bowdle/Hoven areas. Strong winds and some hail, as well as localized flooding, also accompanied this activity at times before it all diminished in intensity by around 10pm.
