I always understood that over 50 degrees it officially is a hot day and all outside work should be adapted to the heat; not so productive. That's why you'll never see a met report over 50..

Hey, you don't need anybody out in the heat to get the temp.....it is temperature in the shade taken by some temperature gauge or probe. Maybe the shady place is at 6 o'clock where the sun doesn't shine!
