Southern Minnesota sees muggy dew points and near-record temperatures Tuesday. Highs will be in the upper 80s to near 90 for some. Thunderstorms are possible late Tuesday afternoon into the evening. Wednesday will be much cooler.

The record high temperature for the Twin Cities Tuesday is 91 degrees set back in 1931. We’ll be rather close to it.

The odds of hitting 90 this late in the season are at about 2 percent, so it does happen, but infrequently. Four weeks ago, the odds of hitting 90 were 5.5 times greater than now.

Tuesday’s high temperatures definitely have the fingerprints of climate change. Climate Central’s climate shift index is at a 3 (out of 5) for much of southern Minnesota Tuesday.
