Isn't it annoying how he only puts on his arrogant "I know exactly what
is going to happen" mode when there is a slow moving high pressure?

The annoying thing is that slow moving high pressures are almost
impossible to get the detail right in winter.

There could be stratus, stratocumulus, or freezing fog. Not even a
genius like Rob with an uncalcualby high intelligence can predict that.

So why does he pretend he can?
