The heat wave is centered in the midwest and will likely extend throughout the entire country with the exception of the Pacific Northwest, according to [projections](http://www.cpc.ncep.noaa.gov/products/predictions/814day/ "undefined") from the National Oceanic and Atmospheric Administration (NOAA). Forecaster expect temperatures to exceed 90°F in many major cities. Places like Las Vegas and Phoenix could experience temperatures that top 110°F, though models this far out are subject to some uncertainty. The unusually hot temperatures come amidst an [extended warm period](http://time.com/4147776/warm-east-coast-weather/ "undefined") that has most climate scientists expecting that 2016 will be the [hottest year on record](http://time.com/4154331/warmest-year-2016-climate-change-el-nino/ "undefined"). The climate phenomenon El Niño and long-term global warming have both contributed to this year’s temperature spike, climate scientists say. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4406219/weather-forecast-heat-wave/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4406219/weather-forecast-heat-wave/"},"headline":"Massive Heat Wave Expected to Hit Much of the U.S. Next Week","datePublished":"2016-07-14T15:18:01.000Z","dateModified":"2026-02-22T23:15:37.165Z","description":"Temperatures could top 110°F in places like Las Vegas and Phoenix","url":"https://time.com/4406219/weather-forecast-heat-wave/","keywords":["weather"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd04a062656509b21/69889bf72dce0118bf9e9d80/heatwave.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Justin Worland","jobTitle":"Senior Correspondent","url":"https://time.com/author/justin-worland/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd04a062656509b21/69889bf72dce0118bf9e9d80/heatwave.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"heatwave","caption":"","creditText":"National Weather Service","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/weather/","name":"weather"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4406219/weather-forecast-heat-wave/","name":"Massive Heat Wave Expected to Hit Much of the U.S. Next Week"}}]}] ```
