Heat indices are expected to reach triple digits today. Caleb Grunski from the National Weather Service in the Twin Cities says today will continue a summer-long trend.

“Overall this summer has been warmer than normal,” said Grunski. “We were four degrees warmer than normal in June and we’ve been two degrees warmer than normal so far in July.”

Grunski was asked why the area has been warmer than normal this summer

“Our weather pattern has mainly brought a lot of warm air from the southwest United States to come up into our region,” said Grunski. “We haven’t a lot of upper-level troughs that have brought cold air in from Canada this summer.”

An excessive heat watch will be in effect this afternoon into this evening.
