Goodness! And that at 24 hours, not at some impossible distance. There
are heavy snow possibilities in that chart for almost anyone in the
UK. It is, still, only a chart though, as you rightly imply Rob, by
looking forward to the next one!
Well, given that the low jumped several hundred miles between the 0z T+36
and the 12z T+24, I don't put much store in the current forecasts pinning
down that snowy area just yet. Of course, the more-than-slight miffedness of
seeing inches of snow turn into 1mm (!) from the latest NAE might have
something to do with my views. I'll look a right old Charlie if that were to
happen, bearing in mind I've booked Wednesday and Thursday as days off work
in expectation of snow.

If the NAE is right, and I suspect it won't be, this part of Kent (Leysdown,
near to the sea) will see all of 1mm of precipitation in the next two days
(to noon on Wednesday). Given the deep cold air, the proximity of frontal
systems, instability - I can't see 1mm being anywhere near right.

It's also interesting that the BBC forecasts have latched onto the 12z NAE
output as the be all and end all, given that it was a big switch from the
6z. Even the MetO's Unified Model shows everything further east!

Michael Fish on the local news will be a worthwhile watch tonight, I feel.
