CHANHASSEN, Minn. (WCCO) – Our 4th of July high temperature of 101 degrees wasn’t the only record set in the Twin Cities this week.

Three other temperature records were broken: the warmest overnight lows on Monday, Wednesday and Thursday.

Byron Paulson of the National Weather Service says the sustained heat is what made the week so uncomfortable.

“Everything warms up during the daytime and when it doesn’t cool off at night, temperatures have such a high baseline to start from again as far as warming things back up in the afternoon,” said Paulson.

It’s those long stretches of unbroken heat that can be dangerous for people without air conditioning, but no fatalities have been reported during the Twin Cities heat wave.
