Just When Will Things Cool Down Around Here? (Spoiler Alert: We'll Tell You)
According to various weather agencies including the National Weather Service, buy a week's supply of sunscreen and keep drinking water.

If you liked the temperature yesterday (in the triple digits), you're going to love tomorrow. More of the same, give or take a degree or two.
Sunday, daytime temperatures will plummet to a chilly 96 degrees, and the rest of the week will be positively arctic -- low 90's, or thereabouts.
If you can hold out for the week following, however, and if you believe a weather forecast is more reliable than reading tea leaves, then expect life to get back to something bearable, perhaps the low 80's by the 23rd.
