Summer heat on the way: Highs may reach 90s in Northland on Monday

Get ready for a blast of summer heat over the next couple of days, as temperatures in the Northland are forecast to climb well into the 80s Sunday and possibly into the 90s on Monday.

Warm, humid air will rush into the region from the south on Sunday. Highs in Duluth are forecast to reach the low to mid-80s, the National Weather Service reported, with gusty southerly winds. Areas to the south and west may reach the upper 80s.

Thunderstorms may accompany the warm air, and there’s a chance some could be strong to severe — particularly in areas north of Duluth.

After mild, muggy conditions Sunday night into Monday in the Northland, highs on Monday are forecast to reach the upper 80s to low 90s across much of the region; heat index values may reach the mid-90s. There may be some relief from the heat near Lake Superior, where highs are forecast to stay in the upper 70s to low 80s.

A cold front is forecast to move across the region Monday night and Tuesday, triggering storms that could again be strong to severe in the Northland. The storms may also bring locally heavy rainfall, possibly in excess of an inch or two in some locations.

The cold front will spell the end of the brief heat wave; forecast highs on Tuesday and Wednesday in the Twin Ports are in the 70s.

The average high temperature in Duluth at this time of year is about 77 degrees; the average low is about 56 degrees.
