FORECAST VS. REALITY
A useful advance call on the coming heat and Henri's development, alongside an accurate recap of the previous week's temperatures; the main refinements are peak heat, cooldown timing and Henri's strength at landfall.
WHAT THE ORIGINAL AUDIO SAYS
Around 90°F in Chicago Monday through Wednesday, August 23–25; a cooldown late in the week; and Henri reaching New England as a Category 1 hurricane.
PUTTING THE FORECAST IN CONTEXT
The host's primary call was around 90°F, but he also explicitly allowed for mid-90s temperatures if the air proved drier. That conditional possibility deserves recognition, rather than treating the realized mid-90s as something the episode never considered. Henri becoming a hurricane and Henri arriving at hurricane strength are separate parts of the forecast.
O'Hare reached 87°F on August 23, 95°F on August 24, and 94°F on August 25, compared with the recording's upper-80s to low-90s expectation.

The predicted late-week return to upper-70s highs did not happen at O'Hare: August 26–28 reached 90°F, 91°F, and 92°F.

The recording's retrospective Sunday-through-Thursday highs of 80, 80, 84, 86, and 88°F do match O'Hare's August 15–19 observations.

Henri became a Category 1 hurricane on August 21, but weakened to a tropical storm before its August 22 Rhode Island landfalls, with maximum sustained winds of 55 knots (about 65 mph).

SCOPE OF THIS CHECK
This station check does not verify neighborhood dew points, heat index, wet-bulb estimates, or St. Louis predictions; hurricane category describes the cyclone's maximum winds, not every landfall location.
