Southern California has been baking in a nasty heat wave for the last five days; it’s expected to last another day. Yet the experimental NOAA temperature outlook says it’s going to be cooler than usual this September, if the blue squares along the California coast can be trusted.
In fact, earlier this year NOAA forecaster Douglas LeComte told me he thought these forecasts were as good as conventional ocean-based forecasts.This month will be a good test for their predictive skill.
