Depicted below are probability forecasts of the daily maximum, daily minimum, and daily mean
heat index reaching or exceeding a given threshold during the medium-range period (Days 3-7).
The three thresholds for the maximum are 95, 100, and 105 degrees F; for the minimum, they are
75, 80, and 85 degrees F; and for the mean, they are 85, 90, and 95 degrees F.
