When the SF temp is predicted to be 75-80 lately, it ends up being 20 higher pretty often. Last two weeks there was two days in a row like this, plus many other times in past few years. Are the weather prediction models outdated, and unable to forecast in the new climate? Forecasts were never perfect, but "in the mid 70s" and "oh @@@@ it's almost 100" are not just a little off. It's not like 80% chance of rain, and then it's a little drizzle and the clouds clear up. When it's going to be a regular 65-70 SF summer day, it usually plays out correctly. It's just when it's supposed to be hot and then it's very very hot. I'm grateful we aren't wiped off the earth by hurricanes tho.
