I’ve gone through some of the parameters with a fine tooth comb, and it does look cold enough for a fair few Doc.

Certainly the risk of rain near Irish Sea coasts.

Correct me if I am wrong but yet again the Azores HP seems to be ruining our fun?

Marginal is certainly the word next week, but I do think a fair few will see snow.

You have to laugh really!

Temps of 9-12c for south if this comes about.

Then again lol. A lot to resolve post 192 but plenty of interest way before then with the met having their work cut out during the oncoming week.

Plenty to look forward to.

Well I certainly wouldn’t have any complaints if the 06z GFS verified. Neither would Saint, or Solar Cycles.

I fear this will be corrected south.

Also posting them in the thread clutters the page, can’t you post the links instead?

Exactly Joe, it adds nothing and these individual charts inevitably, (yet to Sean seemingly surprisingly,) change significantly between each op run. One warm sector on one op run of one model a week and a half away provides little if any insight as to what conditions will be like a week and a half away. In fact based on recent runs even at half a week out it may not be much use in isolation!

Here with the link to the 384 chart: - taste of spring now in the 06z run, with cold air and winter returning to Greece & Balkans etc - although this would be a perfect summer chart with southerly winds:

Still cold messy zonality with short waves popping up unseen.

It's not often that we get this pattern, with several windows for sleet and snow in the next week but huge uncertainties around where and how much, if any.

Fascinating to see the models trying to work out how the atmosphere is responding and wil respond to the conflicting signals.

A degree of consensus starting to build for a band of snow across the south on Tuesday afternoon.

ICON 6z shows a band of precipitation moving east and intensifying as it does so. Could give some atrocious conditions for the Tuesday evening rush hour if this verifies. It becomes very intense over Kent during the late evening

06z GFS parallel showing something very similar. The high res charts are stuck at T81 at the moment.

0z ARPEGE shows a more marginal situation with rain south of the M4

What a lovely run the 6z GFS(P) is, if you're a snow fan. Take a look at the "snow on the ground" chart for next Friday and you'll see that rarest of things, a 98% white UK!

Anyway, of much more significance is the evolution over the next 72 hours.

Curently the GFSP has a significant snow event for Tuesday into Wednesday, as shown by Darren above.
