Crucial Quote

The National Weather Service noted in a Saturday morning forecast discussion that this will be the warmest day of the year so far.

The heat is caused by an enhanced ridge of high pressure known as the Bermuda High, which is parked over the Atlantic Ocean during the summer, and which is best known for influencing the track of hurricanes. Climate scientists warn that more intense and more frequent heat waves will be among the most immediate changes in a warming world.

Less than a year ago, the U.S. experienced one of the most extreme heat waves ever recorded. Portland, Oregon, hit 116 on June 28, 2021, as the highs in coastal cities in Washington and Oregon, which are typically around 70 in early summer, soared above 120. In Canada, the village of Lytton, British Columbia, set the country's all-time record high three days in a row, topping out at 121 on June 29, 2021, before a wildfire fueled by the hot, dry and windy conditions engulfed the village, destroying nearly every structure.
