Episode Narrative A cold front moved across North Dakota on the 26th, with a hot and humid airmass in place ahead of the front. At 6 pm CST, a surface low was located over southern Manitoba (Canada), just north of Pembina, ND. The cold front stretched to the southwest, back toward Devils Lake (ND) and Bismarck (ND). Ahead of the cold front, temperatures ranged in the low to mid 80s with dew points around 70F. Behind the front, temperatures did not cool significantly, but dew points dropped to the mid 40s. Thunderstorms began to form along and ahead of the cold front by early evening (from northeast ND into south central ND), eventually crossing into northwest Minnesota several hours later. Eight distinct tornadoes occurred over northeast North Dakota and northwest Minnesota during this event.
Event Narrative This tornado tracked intermittently to the east-northeast and passed about a mile north of Union. The tornado then crossed into Pembina County, where it dissipated one mile southwest of Garder at 605 pm CST. The tornado had a total path length of 5 miles, and 4 miles of the total occurred in Cavalier County. No damage was reported. The highly visible funnel and its intermittent contact were viewed and reported by several spotters in Pembina and Walsh Counties. Peak winds were estimated at 70 mph.
