Dangerous heat this weekend for the east and west coasts
For the third weekend in a row, an inflexible heat wave will bring dangerous temperatures to much of the United States, with warnings this time stretching from the desert southwest to the New England coast .
The longest lasting misery continues to be centered in central and southern states, including Missouri, Arkansas, Oklahoma, Kansas and Texas, which will “again” see temperatures in the 90s and lows 100 this weekend, said Andrew Orrison, a meteorologist with the National Weather Service.
“We’ve had heat waves that have been quite long in the past,” Mr. Orrison said, but added: “This one is quite persistent, especially for parts of the central United States and in the southern plains..”
Here’s how other parts of the country are faring:
Northeast and Mid Atlantic
Excessive heat set in earlier this week after a relatively mild summer. Temperatures will rise steadily to a crescendo on Sunday, peaking at around 100 degrees. The heat index – a measure of air humidity – will rise to 105. Washington could experience its first 100-degree day in six years on Sunday.
After Monday, the Northeast could see some respite next week, with highs back down around 90.
After also experiencing a relatively mild summer, the heat will settle in for much of the region on Sunday and next week. Away from the coast, highs will be in the 90s in Washington, Oregon and northern California and could reach 100 degrees. In Canada, British Columbia will also experience a warm period.
The heat in the Pacific Northwest is particularly dangerous, as the generally temperate climate means fewer people are used to it or own air conditioners. Last year, more than 600 people died in a heatwave that gripped the region for weeks.
It will be the hottest part of the country on Friday. Interior deserts from Phoenix to Las Vegas are subject to excessive heat warnings, said Nevada Weather Service meteorologist Brian Planz.
Las Vegas could see a high of 112 on Friday, about six degrees above normal, for this time of year. Phoenix should reach 114 degrees. But a monsoon predicted for the weekend will likely bring some relief, Planz said.
Nightfall in the desert does not cool much. Thursday’s overnight low in Needles, Calif., in the Mohave Valley, was 95 degrees.
