As the South and West of the U.S. suffer through more record-breaking heat this weekend, New York City and the Northeast is expecting more rain.

Las Vegas is looking at a scorching record as the temperature threatens to top Sin City’s all-time high of 117 degrees on Sunday or Monday — part of the deadly heat wave that continues to engulf the Southwest.

The National Weather Service issued excessive heat warnings and advisories for more than a dozen states from Washington to Florida.

A staggering 100 heat records could be topple across the country through the weekend, with more than 90 million Americans under heat alerts.

The blistering heat wave may worsen Sunday for Nevada, Arizona and California, where desert temperatures can pass 120 degrees Fahrenheit during the day. Phoenix may also tie its own record on Monday for 18 straight days with 110 degree temperatures or hotter. 

New Yorkers, on the other hand, will experience cool and comfortable temperatures in the Big Apple.

On Saturday, they will see a high of 87 degrees at Central Park with possible afternoon storms and on Sunday, it could reach a high of 82 degrees with a 59% chance of a thunderstorm.

The chance for torrential rains further north is creating a dangerous flash flood risk for much of New England, including Vermont, which was swamped last week with deadly flooding.

Over 90 million Americans are under heat alerts.

Meteorologists at AccuWeather raised concerns about a high-powered rainmaker, known as an atmospheric river, which may affect the Northeast from late Saturday night to Sunday night. This condition, which was blamed for widespread flooding in California in March, is expected to drench the region with a “fire hose” of moisture, Accuweather said.

Northern New Jersey, The Hudson Valley and Western Connecticut could see some of the heaviest rainfall Sunday into Monday, with 1 to 3 inches of rain falling per hour in some areas. Overall, Accuweather forecast 2-to-4 inches of rain for the city and Long Island, and 4-to-8 in the northern suburbs.
