Duluth baked in temperatures in the 90s for a third straight day on Thursday -- the first time that has happened in nearly 12 years.

Until this week, Duluth hadn't seen a stretch of at least three days with highs in the 90s since Aug. 5-8, 2001, the National Weather Service reported. And it's just the fifth time in 30 years that we've seen such a streak -- other ones occurred in June 1995, July 1988 and July 1983.

Thursday's official high at the Duluth airport was 94 degrees, three degrees off the record high of 97, set in 1932. The high was 92 degrees on Tuesday and Wednesday.

But the streak will end today, as highs are forecast to reach only the 70s and low 80s across the Northland in the wake of a cold front that sparked strong to severe thunderstorms in parts of the region Thursday night.

The storms dropped heavy rain north of the Iron Range, across the Boundary Waters and in Grand Marais, and prompted a flash flood watch for those areas overnight. There were reports of some trees down in the Ely and Pengilly areas, along with small hail.

  • As it often does, Lake Superior created a roller-coaster of temperatures along the Duluth lakefront on Wednesday and Thursday. On Wednesday, the air temperature at the Duluth harbor dropped from 90 to 70 between 6:30 and 7 p.m. as winds shifted from the southwest to the northeast off the lake.

    On Thursday, the wind shifted from the northeast back to the southwest, and the air temperature at the harbor rose from 70 degrees at 2:30 p.m. to 93 degrees by 3:15 p.m.
