A sweltering heat wave could deliver the Twin Cities its first 100° day of the summer this week.

Threat level: A "dangerously hot" excessive heat advisory takes effect across the metro region late Tuesday morning and is expected to last through Wednesday night.

  • Temperatures are forecasted to hit the high 90s, with heat index values — what it actually feels like — soaring above 110.

The big picture: The last time we saw triple-digit temperatures in August was in 1988 — 35 years ago, per the National Weather Service.

  • The agency has only recorded August highs over 100 seven times in the last 150 years.

Plus: Wednesday's forecasted high could break the daily record of 97°, per the Star Tribune.

Of note: Breaking triple digits would be one of the latest 100° dates in Twin Cities history, but not the latest. NWS records show a 104° reading in September of 1931.

What they're saying: The NWS warns that the high temperatures and humidity "will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities."

  • Roads could buckle as a result of the high temps, forecasters warn.

Zoom out: The Twin Cities isn't the only region experiencing high temps this week. A record-breaking heat dome will sit over much of the central U.S.

Be smart: Drink lots of water and stay indoors in an air-conditioned room if you can. Keep an eye out for vulnerable neighbors, including the elderly and young kids, and pets.

What's ahead: The heat will stick around for Thursday's start of the State Fair when highs should be in the 90s, but it's expected to break over the weekend.

The bottom line: We may be sweating now, but as NWS playfully noted online, we'll be shivering under piles of snow again before we know it.
