Low temperature forecast for Saturday morning, August 17. Source: https://graphical.weather.gov
High temperature forecast for Saturday, August 17.
Some changes have occurred in model guidance for next week with cooler risks returning to the Northland for the middle of next week thanks to an upper low/trough which digs south/east out of Ontario which causes an upper ridge (warm air) to build north into western Canada. This will cause a northwest mid/upper level flow and cooler weather to spill into the upper Midwest and Great Lakes during the middle of next week.

Here’s the temperature anomaly forecast valid for August 19-24, 2019 per 12z European ensemble model. Remember a few days ago this model showed widespread above normal temps in the U.S.; but now we’re looking at below normal temps (blue colors on map) for the upper Midwest and Great Lakes. This doesn’t mean we won’t have a couple warm shots mixed in next week, because we likely will, it’s just that the warm weather doesn’t look like it will stick around for very long.
Isolated showers will end this evening which will be followed by clear to partly cloudy skies with areas of fog. Lows will be in the lower 50s to lower 60s with south or southwest winds.
A warm day on Saturday with highs in the 70s along the North Shore to the low and mid 80s elsewhere. Dew points ranging from the upper 50s to lower 60s so not terribly humid on Saturday. Winds south to southwest 10 to 20 mph. A few showers and thunderstorms are possible Saturday in northern Minnesota, dry elsewhere under partly cloudy skies.
Showers along with a few thunderstorms Saturday night through Sunday morning as a cold front crosses the area. Heavy rainfall is possible mainly in north-central Minnesota.
Cooler weather returns Sunday with highs in the 70s along with northwest winds 10 to 20 mph.
