Unusually high temperatures in the Southern and Northeast US on Saturday broke records marked on the same day in previous years.

Much of the country, which stretches from Texas to the Northeast, set new daily temperature records over the weekend.

Marc Chenard, a meteorologist with the National Weather Service, said above-normal temperatures continued Sunday, largely in the Northeast in Connecticut and Massachusetts.

Chenard said that a record-breaking early-season heatwave “isn’t common, but it’s not unprecedented”.

Nearly 20 million people have under heat advice by Sunday afternoon, a number had dropped to about 15.8 million by evening.

Scientists have discovered that Climate change is both intensifying and increasing its likelihood of heat waves. While Chenard said he was unable to determine if any of the events were caused by climate change, the meteorologist attributed the unusual temperatures to fluctuations in weather patterns.

“If you think of this pattern as ocean waves, when the waves are flatter, temperatures tend to be more normal across the country,” he said. “However, as the wave becomes more amplified, you have larger peaks and larger drop-off. Where you have peaks, you tend to have warm air moving northward resulting in temperatures. higher than normal… and where you have depth you’ll have colder air pushing south leading to lower-than-normal temperatures.”

That’s why, Chenard said, we’re also seeing unusually cold temperatures over parts of the Rockies and Plains this weekend.

Below is a summary of new temperature records for each calendar day set this weekend in the Northeast and Southern regions, according to data provided by the NWS on Sunday afternoon. While these numbers are preliminary, the meteorologist added, they are unlikely to change much in the record books, if at all.
