UNITED STATES — THE MID-SOUTH HEAT REGIME HELD: 0 EXTREME HEAT WARNINGS, 12 HEAT ADVISORIES AT A 105-110 F INDEX ACROSS NINE STATES

Steady on the count, a touch lower on the index. The acute tier reads 0 Extreme Heat Warnings while 12 Heat Advisories cover Oklahoma, Arkansas, Louisiana, Mississippi, Illinois, Missouri, Kentucky, Tennessee and Texas at a 105–110 °F index. The tier that makes headlines is empty and the tier that reaches people working outdoors is the one that is live — both of those sentences are true at once, which is why they are printed together.

50 turning points on record since Jun 9 — the 8 most recent shown.
