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.
