Heat dome bakes millions across central US before pushing New York, Philadelphia temps toward triple digits

On the first day of astronomical summer, millions of people across the central U.S. and Great Lakes are under heat alerts as a sprawling high pressure system, also known as a heat dome, is forecast to push temperatures in the Northeast toward the triple digits.

According to the FOX Forecast Center, the stout system will move eastward across a large swath of the country. This will bring sweltering heat to major cities from Chicago to Detroit to the major urban centers along the Interstate 95 corridor on the East Coast this weekend.

New York City and Philadelphia will flirt with 100-degree temperatures into early next week, which is rare for June.

The second round comes Friday evening as more storms develop from Montana into Minnesota. They are expected to continue through the overnight hours, eventually arriving in the Upper Peninsula of Michigan.
