A heat wave not seen in decades

A heat wave not seen in decades will send temperatures soaring for
more than half the US population

 A long-lasting and expansive heat wave fueled by an intense heat dome
will grip the Midwest and Northeast with record-breaking high
temperatures into next week, ushering in the start of summer with this
year's most significant heat event yet.

Hundreds of records could be tied or broken this week as a massive
heat dome parks over part of the East. Multiple all-time June high
temperature records could fall as the heat rises to levels normally
seen only on the hottest July days. Parts of the Midwest to the
Northeast could endure the longest heat wave they've seen in decades,
the National Weather Service's Weather Prediction Center said.
