KEY MESSAGES

- Widespread rainfall is forecast late Sunday into Monday. There is a 70 percent chance for soaking rainfall of 1 inch or more within southeast North Dakota into Minnesota.

..Soaking rainfall late Sunday into Monday

As the stacked upper low departs, a more robust shortwave trough will move out of the Central Plains into Upper Midwest. This wave will tap into richer moisture from the south as well as some instability aloft feeding into the heart of the wave. This will bring widespread rainfall into portions of eastern ND and MN, including a soaking rainfall of at least 1 inch Sunday overnight into Monday.

While there is high confidence in this occurring, there remains some disagreement on which locations in our area will exceed 1 inches. As of now, west-central to north-centtral MN currently hold relatively highest chances for 1 or more inches of rainfall, around 70% chance. Northeast ND into far northwest MN hold relatively lowest chance. Latest CAMs reveal locally highest rainfall amounts should sit in the 2-3 inch range, and will be dependent upon locations experiencing steady rainfall overnight Sunday as well as into Monday. There is a 30% chance for this to occur in our area.
