From The New York Times:
This summer has already produced record-high temperatures across the United States that have caused hundreds of heat-related deaths, and the forecast for next week suggests there will be few places to find relief.
The hot weather recently blanketing the Montana area — Billings has already had 12 days above 95 degrees this month — will head east throughout the Northern and Central Plains over the next few days, the National Weather Service said. And by next week the Great Plains and Midwest — along with parts of the East — will have highs that are 10 to 15 degrees above average, according to Weather Service projections. That heat, combined with high humidity, could make it feel like temperatures have reached the 100s in some areas.
