Minnesota set for hottest period in 4 years with temps nearing 100

Publish date:

Wednesday marks the start of a three-day heatwave across Minnesota that weather experts say will be the "peak" of the summer heat.

Temperatures in the southern half on the state, including the Twin Cities, are set to rise towards the 100 mark, and combined with the humidity it could feel 10-15 degrees hotter.

The last time the Twin Cities had 100-degree weather was on July 4 and 6, 2012, according to the Minnesota Department of Natural Resources.

The National Weather Service has already warned that the next three days will be "dangerously hot and humid," with temperatures expected to peak on Thursday and dew points of between 75 and 80 expected.


Accuweather suggests the dew point in the Twin Cities could hit 78 degrees on Thursday – one of the highest levels experienced in the metro (the record is 82) – and this will send heat indices shooting to between 100-112.

An excessive heat warning is in place from 1 p.m. Wednesday which will continue through 7 p.m. Friday, according to the National Weather Service. By 1 p.m., the heat index in Northfield had climbed to 109 degrees, the weather service says.

Heat is the biggest weather-related killer in Minnesota, according to the NWS, which is advising people take precautions to ensure they stay safe.

Thunderstorms first

But before the intense sunshine arrives, the southern half of the state will get some heavy rainfall as scattered thunderstorms roll through Wednesday morning.

The NWS is predicting "quick heavy downpours" that could cause water to pool on roads and in low-lying areas.
