Discussion: The NOAA observed U.S. gas population weight HDD for NOV-24 was 466 (Fig. 1). The value is somewhat warmer than the 2000-24 normal and the 10-year normal. NOV-24 ranked tied for 3^rd warmest since 2000. The warmest November this century was in 2001 (421 HDD). Going forward, the U.S. gas population weight HDD is near or slightly colder than the 2000-24 normal. The DEC-24 HDD forecast increases slightly due to the very cold start of the month in the East to 857 HDD’s which ranks 12^th coldest this century. The JAN-25 forecast increases slightly to 926 HDD’s ranking 16^th coldest this century. FEB-25 is cold in the West but warm in the high energy demand East and is unchanged at 789 HDD’s ranking 13^th coldest this century. MAR-25 is adjusted slightly colder to 628 HDD’s ranking 14^th coldest this century. Overall, the NOV-MAR 2024-25 U.S. gas population weight HDD ranks 15^th coldest this century (Fig. 2).
