Heat Wave

 NY Times: Heat Wave - Dangerous High Temperatures Stretch Across the South - A dome of high pressure that has baked parts of the region for more than a week will drive the heat index up to 120 degrees from Missouri to Florida, forecasters say.

Temperatures will climb up to 20 degrees above normal...through at least the weekend, reaching the high 90s or low 100s in many places. The heat index — a measure of how heat and humidity make the air feel — will be even higher.
