US heat wave continues to bring scorching temperatures along East Coast

The heat wave that has already scorched many parts of the U.S. will continue to sear most of the mid-Atlantic region on Sunday before moving to the south early this week.

The National Weather Service (NWS) said in a forecast Saturday that the “significant” heat wave will continue into this week, with temperatures of the upper 90s expected. The service said that the mid-Atlantic and the I-95 corridor from Washington, D.C., to New York City will “likely peak” this weekend, possibly hitting 100-degree highs.

The Southeast, mid-South and the Plains regions will see the heat wave peak this upcoming week, with the possibility of temperatures exceeding 110 degrees on some days, according to NWS.

In its forecast discussion for Sunday, NWS said that numerous “record-tying/breaking highs are possible for the Mid-Atlantic.” The service also said the heat wave will shift from the mid-Atlantic to the South by Monday.

“Humidity helping to push heat index values into the low 100s as well as warm low temperatures generally in the mid-70s, providing little relief from the heat overnight, will make this heat most dangerous for portions of the Mid-Atlantic, Southeast, Lower Mississippi Valley, and Southern Plains, with heat-related advisories and warnings in effect for some areas,” NWS said in its discussion.

According to NWS, most of the I-95 corridor between D.C. and New York City is under a heat advisory. Many parts of New Jersey are under an excessive heat warning until 8 p.m. Sunday, with heat index values reaching 107 degrees in some areas.

AccuWeather meteorologists also predicted that the heat wave would cool off in much of the Northeast on Sunday but could lead to thunderstorms.

“This change in the pattern will first lead to an increase in thunderstorm activity across the Northeast and Midwest regions,” AccuWeather senior meteorologist Brett Anderson said, according to AccuWeather.

“Cooler air will first dip into New England while the worst of the heat gets squeezed into the Middle Atlantic and Southeast,” he added.
