 Must be time for the KNOX American Federal Bank five-day forecast from staff meteorologist Mark Ewins. Hazy sun and 91 degrees today. Heat indexes are going to be very warm because we've got some humid conditions out there to go along with it. South winds today, 12 to 22. Tonight, mostly clear, 68. Southerlies to 18. And then tomorrow, sunny, hot and humid again, 92. Again, the real issue today.
