Showers and thunderstorms with heavy rainfall south of the border tonight into Saturday.. flash flood watch in effect for North Dakota
A low pressure area will track across North Dakota tonight into Saturday, bringing widespread thunderstorms with some heavy rainfall likely generally near and south of the international border. Local rainfall amounts of 50-75 mm are possible in these areas overnight into Saturday, and flash flood watches are in effect for much of northern ND. There will be a sharp cutoff to the rain north of the border with little rain expected over the northern Red River valley including Winnipeg. This will be the latest in a series of convective weather systems that have brought thunderstorms and heavier rainfall over the southern RRV into North Dakota over the past few weeks. While the northern RRV struggles with very dry conditions since the end of June, it's been a different story south of the border where rainfall has averaged above normal in July in many areas.
