huge snip of interesting stuff

Surface charts don't always show the whole story, particularly with
blocked anticyclonic features.

It's interesting to look at the 06Z ASXX, as that now has a "trough" pasted
into the northerly flow, just to the north of that band of rain. The
inclusion of such a feature is often done to illustrate the effects of an
upper feature on surface conditions.
