Sunday is shaping up to be a great day to stay inside, watch the Vikings against the Bears and fold some laundry. Outdoors, it'll cool, damp and downright dreary.
High temps will scrape into the low 60s but that's about it, as cloudy skies and occasional showers dampen the day. Later Sunday, strong to severe storms could develop in South Dakota and move into western Minnesota, where there is a slight risk for severe thunderstorms.
Sunday's showers and storms will be followed by another round of storms Monday into Tuesday. The NAM 3KM weather model's simulated future radar (GIF may not load in all browsers) shows numerous bouts of heavy rain in southern Minnesota through Tuesday.
According to the National Weather Service in the Twin Cities, there could be widespread rain totals of 1-2 inches on Monday, with isolated 3-inch totals near the Minnesota-Iowa border.
In addition, isolated storms could reach severe levels Monday with all hazards possible, including hail, high winds and tornadoes. An outbreak of severe weather is not expected, but there will be plenty of juice in the atmosphere for powerful storms.
High temps Monday will shoot into the low to mid 80s in eastern and southern Minnesota, along with very humid conditions as the dewpoint is forecast to reach at least 70 degrees. In other words, it's going to be sticky outside.
Once the showers and storms leave the region Monday night or Tuesday, much cooler air is expected as overnight lows later in the week will dip in the 30s and 40s for much of Minnesota.
