A warm front moving east from western Minnesota could bring showers to parts of the Northland late Monday afternoon into the evening. These showers will be supported by a strengthening southwest low-level jet reaching up to 35 knots, along with warm air and moisture advection.
Most of the Northland is expected to see less than 0.1 inches of rain Monday evening, though some spots could get a bit more.
The upper Midwest will see northwest winds aloft this week, but forecasts show a shift to southwest winds aloft by next weekend. This change could bring a stretch of active weather late next weekend or early the following week, along with warmer temperatures, with highs possibly climbing into the 70s and even low 80s across much of the Northland next Saturday and Sunday.
