Minnesota is under an excessive heat watch for rising temperatures that are expected to start Sunday.
The prolonged significant heat wave is expected to start Sunday and end Wednesday - with record highs in the mid-90s. The wave could move into western Wisconsin. Dew points are expected to increase into the mid- to low-60s.
As of Friday, temperatures in the metro were expected to reach 93 degrees by 1 p.m.
The heat is affecting fairgoers at the Minnesota State Fair, too. Typically, temperatures during the State Fair on average are above 90 degrees at least one day, according to KSTP.com Meteorologist Jonathan Yuhas. The hottest day was 104 degrees on Sept. 10, 1931.
This year, temperatures are expected to be above 90 degrees from Sunday through Thursday - and possibly even through next weekend depending on whether thunderstorms develop, Yuhas said. Storms could cool down temps.
The forecast so far estimates that temperatures will be above 90 degrees for at least five days at the State Fair - which would make this year one of the hottest years at the State Fair.
