Another Heat Wave Brings Unbearable Temperatures to Parts of the U.S.

Key Points:

• A widespread heat dome is causing dangerous, record-breaking temperatures across the United States, moving from the West to the Upper Midwest, Northeast, and eventually the Southeast throughout the week.
• The Upper Midwest, including North and South Dakota, could see highs between 95 and 105 degrees Fahrenheit on Monday, with the heat spreading to the Northeast by Tuesday and the Mid-Atlantic by midweek.
• Heat advisories are in effect from Pennsylvania to Maine, with cities like New York and Boston expecting temperatures in the 90s and heat index values reaching the low 100s, potentially breaking daily records in areas such as Syracuse and Manchester.
• The heat dome, a strong high-pressure system, has trapped hot air over much of the Western and Central U.S., leading to record highs like 109 degrees in Salt Lake City and 111 degrees in Billings, Montana.
• While the Northeast and Great Lakes may see relief by midweek due to a slow-moving weather system, the Southeast, including the Carolinas, Florida, and parts of the Deep South, will face continued heat with temperatures in the low-to-mid 90s through the weekend.
