The colder weather of this week and into next won't last long.

This one was pretty much bang on. You could have put your trust in the model output from 10 days ago, to have shown you what the weather would be like today. It certainly is possible to use models to forecast at 10 days, on occasions. Much of the time, however, you can't trust them to do so.

After this re-establishment, it's looking zonal now to the end of January at least.
