Partly to mostly cloudy skies Tuesday night with a chance for showers and thunderstorms. Lows will be in the 60s to lower 70s with 50s along the North Shore of Lake Superior.

Very muggy and warm weather Wednesday and Thursday with dew points ranging from 65 to 75 degrees while high temperatures rise into the 80s and 90s with cooler temperatures along the North Shore of Lake Superior.
Showers and thunderstorms are possible at times in parts of the Northland mid to late week but warmer temperatures aloft (CAP) may prevent storms from developing, but if they can develop they could be strong to severe with lots of instability, moisture and warm air in place along with some wind shear. Torrential rainfall, high winds and hail would be the main threats if storms can develop during the mid-late week time frame.
