We’re sweating through what looks like the longest early-season heat wave for the Twin Cities and parts of Minnesota.

Monday marks the fifth straight day of 90-degree heat in the Twin Cities and much of western and southern Minnesota. You can see the individual daily highs above. We also set daily record highs Friday and Saturday in the Twin Cities and several other locations.

If we hit 90 as expected Tuesday, it will tie the record of six days as the longest streak of 90-degree days before June 15 in the Twin Cities. That has happened three times, lastly in 2018.
