Oh yes - I was just playing fantasy 7-day forecasts. I often lay
weight to the longer range forecast if there's an agreement between
the models, but whose to say that they're not all wrong.

Already the midday 1s and 2s forecast for next Monday have been
replaced by 5s and 6s with the thrust of the colder air further east.

Move along now, nothing to see here !
