With precipitable water values in the top 10% for time of the year, the atmosphere was primed with moisture, setting the stage for a widespread rain event. An approaching low pressure system from the Rockies brought multiple rounds of rain to much of the Northern Plains, much of which came from convective thunderstorms. Most areas saw within the range of a half an inch up to 1.5 inches. The Devils Lake Basin and areas north of Bemidji saw lower totals, generally near or less than a half an inch. The heaviest totals were seen near Wahpeton where some areas saw rainfall of 3+ inches. Southeast of the city of Grand Forks also received more than 2 inches. Since the totals fell over a long period of time, flash flooding was not a large concern as in the previous weekend.
