For reference, this is what the EPS was showing for this general period (it's off by one day since I didn't save the map for this exact period, but doesn't change much). There's no denying the EPS has been overestimating the extent of warm anomalies in the 10+ day period.
The CDD record was broken because it was historically hot in the places that average lots of CDD in the first place (IE: it was hottest in the climates that are already the hottest).
So yeah, even if the (preliminary) lower-48 anomaly didn’t break the record, the magnitude of the heat itself was record breaking.
They banned them in Snohomish County full stop and sales will stop next year. I am hoping that we will treat the possession of them like any other explosive and get them off the streets. Fireworks have no place in a modern society.
