Another slow moving storm system produced heavy rain over much of the Red River Valley of the North on Wednesday June 13th and Thursday June 15th. Portions of the Red Lake River basin in northwest Minnesota received over 5 inches of rain. Rainfall in the far southern Red River Valley has caused the river to begin to rise again in the Wahpeton and Fargo areas. Based on recent and forecast rainfall, moderate river flooding is forecast to continue in the Fargo/Moorhead area, with moderate river flooding forecast for East Grand Forks and Oslo Minnesota.
Overland, agricultural flooding is still a serious issue in much of the region as well. The most significant flooding is south of the Fargo/Moorhead area. Other areas north to the Canadian border are experiencing some low land agricultural flooding as well.
Additional heavy rain is possible across portions of the region this weekend into early Monday of next week. At this time, it is not possible to pinpoint the exact location of the heaviest rainfall. It would appear that the far northern Red River Valley is most likely to get heavy rains. There will be a very unstable airmass in place over the Red River Valley Sunday afternoon. A cold front will become the focus for strong thunderstorms during the day Sunday, and into Sunday night. At this time there is a fair amount of uncertainty where the strongest thunderstorms and heaviest rains will fall.
