It's going to be brutal outside

Ever thought about what it's like for the crawfish entering the pot? Anyone outside in Baton Rouge this week is about to find out. Something dubbed a "monster heat dome"—the strongest on the planet right now—has decided to call the central U.S. home this week, and Louisiana's forecast high tops out at a brutal 107 degrees.

Why it matters: Heat this intense turns routine outdoor time into a health risk, and forecasters don't expect real relief until late week.

The forecast: Baton Rouge's midweek outlook, according to the National Weather Service, is about to turn Hades hot.

• Heat Advisories are likely Monday and Tuesday, with an Extreme Heat Warning possible by Wednesday.
• Afternoon highs push into the upper 90s, driving heat index values as high as 115 degrees.
• Overnight lows barely dip below 80, leaving little time to recover before the next day's sun.
• Rain chances stay capped near 10% to 20% through midweek, so a stray shower won't save you.

Not just here: The same system is baking a wide corridor from the Dakotas to Texas in triple digits, according to The Washington Post.

The bottom line: This heat sticks around through Wednesday, and only a weak front late in the week offers any real shot at relief.
