Heat wave day No. 6: Record tied for longest early-season heat wave in Twin Cities

Welcome to day No. 6 of what is almost certain to end as the longest 90-degree heat wave on record before June 15 in the Twin Cities.

The temperature at the Minneapolis-St. Paul International Airport topped out at 96 degrees again Tuesday as of this post.

That’s the sixth straight day of 90-degree heat in the Twin Cities and most of southern and central Minnesota. That ties the early-season record for the longest streak of 90-degree days before June 15 in the Twin Cities. This record was last tied in 2018.

Third longest heat wave on record?

It looks like our string of 90-degree days will run through Thursday and possibly Friday. Highs Wednesday again push into the mid- and upper 90s across most of southern and central Minnesota. It’s a steamy copy-and-paste forecast for Thursday, too.

If we manage to hit 90 degrees Friday in the Twin Cities, that will put our current 90-degree day streak at nine days. That would tie the third longest streak of 90-degree days ever on record for the Twin Cities. The longest streak is 14 days in the brutal summer of 1934.

Weekend relief

A weak cool front slides through Minnesota Friday night. The weekend will be slightly cooler and noticeably less humid. Highs will be in the 80s to around 90 this weekend (vs. 95 to 99 the past few days) and dew points will fall into the more comfortable 50s.

So we’ll get a break from the intense heat this weekend across Minnesota.
