 I'm hopeful that this can be a turning point and that brighter days could be ahead. That's what I'm hoping and praying for. Nick Eineli, WTOP News. We've been telling you about the extreme heat being felt across the region today. We've now broken a record for the day by reaching 101 degrees. And there's a difference between the actual temperature, of course, and the heat index. WTOP's Scott Gelman has been out and about in this horrible weather asking people whether they know the difference.
