Summer heat is on the way from coast to coast, forecasters say, with high temperatures well into the 80s and 90s and even 100s in some areas.
In fact, the national temperature outlook map for June 11-17 shows that above-normal temperatures are forecast for the entire lower 48 states.
A “period of record-breaking heat and increasing humidity is possible across much of the country into the middle part of the month,” said Washington Post meteorologist Ben Noll.
The heat wave will be the result of a strong ridge of high pressure that’s expected to set up over much of the country, the Climate Prediction Center said.
