Freeborn County no longer is in an excessive heat warning, but the National Weather Service kept the area in a heat advisory through today.

The advisory also is in effect for counties to the north and to the west of Freeborn County.

Heat index values were forecast to reach 100 across much of southern Minnesota, including the metro area.

The forecast in Albert Lea for Friday calls for heat index as high as 95, with a high near 89.

Classes begin at Albert Lea Area Schools on Tuesday, which has a forecast high of 78.

Sweltering heat has prompted Minneapolis Public Schools to cancel classes in more than two dozen buildings for the rest of the week.

The district canceled classes Thursday and Friday in buildings lacking air conditioning. Classes at those sites will resume Tuesday, after Labor Day weekend.

Students won’t have to make up canceled days. All other sites will remain open.

Minneapolis public schools have 18 buildings that lack air conditioning and another 11 with only limited cooling, so schools provided water to help keep students and staff cool and hydrated.

But some students had complained about going to class in the stifling heat.

The district says it determined it could not sustain the level of support needed for student health and safety at those locations for the rest of the week.
