Not sure if it's just my tablet but since you posting charts the last 24hra Gooner they appear as

huge wide posts for me.

All ok on my Samsung tablet.

What I like about the fax charts (apart from the fronts being drawn on) is that at this point you can click between T+72 and the T+84 with both displaying 12UTC Sunday, the difference being the latter was derived 12 hours earlier. Look at the differences in the occlusion across the South and S.E. It might not look that massive but those small differences with its position will make a big difference on where it will snow and rain and how much. It all looks very much in the melting pot still to me.

The 18z is pants for the Midlands on Sunday, but good for the north. Clearly the path of the slider low is not settled yet.

It has never looked like being settled. The range of outcomes should narrow as we get closer to Sunday but from experience even the 00z Sunday runs won’t be exactly right. How many times has the precipitation pattern on the radar looked like the predicted one even 6 hours out?  Additionally the short range models change with every run.

I’d say that nothing is certain yet except that a slider will move south-east. Based on recent output most likely it will traverse the country somewhere south of a line from The Wirral to The Wash and possibly as far south as the Severn Estuary to Kent. Even that might be too tight a spread at the moment.

ECM shows everything further south, it seems, with snow in the SE on Monday. Sunday's snow is centred at the same latitude as Birmingham.

You can see all the details here:

(That's the full ECM output, in 3-hourly intervals).

Shamelessly stolen from NW, the ECM ensemble meteograms for London, including (but not limited to) 850s, 2m temperatures, snowfall etc. Interesting to see that yesterday's 12z suite actually had some -10 850s, albeit in the coldest 10% of members.
