It may be a dubious spot in the record books, but we did it.

Our record early June heat wave reached nine straight days at or above 90 degrees Friday. That’s the third-longest streak of 90 degree days on record in the Twin Cities.

Weekend relief

A cool front blows in a noticeably cooler and much less humid air mass for Saturday. Highs Saturday will reach the upper 80s across much of southern and western Minnesota, with some comfy 70s up north.

Highs returns to the 90s Sunday in southern and western Minnesota with 70s and 80s up north.

Dew points plunge

The biggest change in our inbound air mass is much lower dew points. Watch NOAA’s NAM 3 km resolution model sweep out the dew points near 70 degrees and blow in fresh air mass with dew points in the 50s and 40s overnight into Saturday. The loop below runs from 6 p.m. Friday to noon Saturday.
