More accustomed to sweatshirts than sweat, Minnesota's North Shore on Friday morning became the nation's hottest geography, with Two Harbors, Minn., hitting 90 degrees, the Twin Cities National Weather Service office reported.

It was nearly 20 degrees hotter by the lake compared to Death Valley, Calif., or Phoenix.

At 10:30 a.m., Duluth hit 87 degrees, crashing through the record high temperature of 82 degrees, according to the Duluth National Weather Service office.

Later in the day, another record fell: Minneapolis-St. Paul International Airport posted its first 90-degree temperature of the season, breaking the daily record of 89 degrees set more than 80 years earlier.

The good news for heat-haters? A cold front is expected to push across the region tonight.

Highs will be closer to normal on Saturday, MPR News meteorologist Ron Trenda notes in today's Updraft blog post.

Highs in the 60s will be common Saturday over much of Minnesota, with some lower 70s possible, Trenda said. Mother's Day will be pleasant.
