American weather stations broke 332 daily heat records on Friday across 19 states, against zero cold records, according to the NOAA station data tracker that measures each thermometer against its own history since 1970. The count is still rising as late-reporting stations check in. [1]

The state leaderboard is where geography gets specific. Idaho took the worst of it with 35 broken heat records, Oregon logged 14, and Texas 13. Stampede Pass, Washington erased a record that had stood since 1970, jumping from 81 to 86 degrees. Portland, Arkansas hit 107 degrees, six past its 1983 mark. [1]

The arithmetic behind the count deserves stating, because the ratio is doing the arguing online. A stable climate would be expected to produce roughly 68 record highs on a given day; 332 divided by that baseline comes to about 4.9 times expectation, a step up from Thursday's 241 records at roughly 3.4 times the same yardstick. [1][2] That ledger and what it implies are in yesterday's paper.

Two consecutive days prove a pattern the way two bricks prove a wall, barely, except this wall has been accumulating all summer across the Mountain West and the Plains while national coverage filed the tally under weather, not news. The stations do not editorialize. They simply report that Friday was hotter here, and here, and here, 332 times before sunset.
