MINNEAPOLIS (WCCO) — Another sticky, sweaty summer day was upon us with a high reaching 93 and a heat index of 110 degrees. But some cloud cover keep the temperatures lower on Sunday, which might not be the case for Monday.

Meteorologist Ron Trenda said there is still a chance of showers and thunderstorms Sunday, especially in northern Minnesota.

The highest heat index, a combination of heat and humidity, readings were around 110 degrees for the afternoon. The record high for this date is 99 degrees, which was set in 1936. Average highs for this time of year is around 84 degrees.

An excessive heat warning is in effect until 9 p.m. Wednesday. The hot and humid conditions will lead to a heightened risk of heat-related stress and illnesses.

Folks are urged to take extra precautions if they work or will be spending time outside. Strenuous outdoor activities should be rescheduled to early morning or late evening.

Other precautions include wearing lightweight or loose fitting clothing and drinking plenty of water.

At the USA Cup in Blaine, games were suspended due to the elevated heat index, which had a reading of about 105 at 1 p.m. The games were said to be suspended for a minimum of at least three hours. Games restarted at 4 p.m.

Medical crews at Target Field were kept busier than usual with a number of people needing treatment for heat-related issues.

Kevin Smith, executive director of public affairs for the Minnesota Twins, said most of the people seeking treatment were elderly. He said it’s a strong message for fans coming to Monday’s game to dress accordingly and be aware of the heat.
