With temperatures rising to 10 to 30 degrees above average, dozens of records were demolished Tuesday across Wyoming, Utah, South Dakota, Nevada, Arizona and Southern California.

Many other Western cities saw similar, even more extreme events: Billings, Montana, shattered its daily record by 10 degrees (new record: 108), and Chula Vista, California, smashed its record by a whopping 13 whole degrees (new record: 89).

All-time record temperatures were tied on Tuesday in Billings at 108 degrees, Salt Lake City at 107 and Cheyenne, Wyoming, at 94.

With the heat wave not expected to diminish until next week, more than 200 warm records could fall, including afternoon record highs and overnight lows that fail to cool down.
