Duluth hit 88 degrees Sunday; International Falls 91

Talk about it

DULUTH — The Northland roasted in the heat and humidity along with much of the rest of the country on Sunday.

The high temperature at the Duluth International Airport was 88 degrees, while International Falls reached 91. Those weren’t records, though — Sunday’s record high at both Duluth and International Falls was 94.

Ashland hit 93, according to the National Weather Service, while Superior and Two Harbors reached 90 and Hibbing recorded a high of 88.

The humid air pushed the heat index well over 100 in many parts of the Northland on Sunday afternoon. Storms that moved across parts of the region late Sunday tapped into that humidity and dropped heavy rain in some areas; a flash flood warning was issued for parts of Northwestern Wisconsin during the evening hours.

An excessive heat warning remained in effect Sunday night for much of the Northland, including the Twin Ports, through late Wednesday. High temperatures are forecast to reach the upper 80s and into the 90s today through Wednesday.
