The U.S. population weight CDD forecast for the 2023 warm season (MAY-SEP) is adjusted slightly cooler as in general areas at risk of hot weather re generally not high demand electricity areas (except Texas). The 2023 forecast is markedly less warm than the past 3 years.

Evaporative drought demand index did a good job recognizing the fire risk to Canada and maintains a dry atmosphere/soil moisture combination into the northeast quadrant of the U.S. during early June.
