Actually, it’s been going on now (colder temps) for more than a year.
I always save my monthly electric bills from Puget Power.
Each month, it shows average temperature for the month, and the average temp for the same month last year.
I believe every month this year was colder than the same month last year, and every month last year was cooler than the same month in 2008.
I’ll have to dig them out and maybe do some stats...
I sure wish Clark Public Utilities would do that for us, but they would probably raise rates another 5% to pay for it.
