Ignoring snow potential etc could be a very wet day on Monday if GFS has the low pressure development right

Monday does indeed look foul in my area on the latest GFS. 3C and heavy rain. Could be some sludgy snow a bit further north though.

Tuesday to Wednesday was previously looking as though it could have some snow chances down here but the latest charts show the typical dry northerly for the south with less LP influence.

I'll admit, I had a bit of hope we'd get a 5-10cm fall overnight Monday into Tuesday (albeit a little wet), followed by at least a week of temps cool enough to sustain the lying snow. That looks a forlorn hope from the latest output (and the trend of output)

I'm not going to rule out the chance of a surprise even down here but things do seem to be heading the wrong way. 
My iPhone weather app still says sunny with zero precipitation on Monday, so a bit different from the GFS!

Long fetch SW on this op run wonder if this is a new trend. Does seem to be changing in the medium term quite significantly at the moment. But 21/22nd seem to signal the end of the cold snap

The period Mon - Thurs next week is, predictably, looking rather uninspiring for the majorty of the country. There is a chance of course of snowfall but as ever it's (repeated ad nauseum) marginal.
Looking a little blocky again toward the end of the run but again no strong signal.

A bit less promising but a cold snap coming for sure. After that it doesn't look to me like endless zonal gunk with several windows of high pressure. Okay, they may not form where we want them but it does look like the prospect of some brighter, less windy weather at times and the chance of night frosts. Much better than the 4 weeks of wet windy weather we've just had. Interesting that last January, though mild, was very dry and the start of the big drought down here. Very different story this January.

First thing this morning, it's had changed to 4 hours of light snow overnight Mon/Tue.

Now it's showing dry throughout.

The GFS 6z, however, now shows pretty widespread snow on the NW England/N Wales region through Sunday, culminating in some very heavy snow across there plus S&W Yorkshire:

Almost certainly overdoing the snow risk as it's really marginal (-4c 850s and 528dam in a turbulent flow). Nice to see, however, the warm sector being in the east, when it's normally in the west, though 😋

Still, given the chart volatility, I expect it to look a whole lot different come Sunday.

One of my old friends who lives in Australia is in the UK at the moment. They arrived the day after the December cold snap ended and have endured wet windy dross for the whole time they’ve been here. They fly back on the 20th so will be hoping their kids who have never seen snow might get to see a flake or two before then, although the chances seem to be diminishing after yesterday’s glimmer of hope.

Yes the period Monday to Thursday could maybe even should hold some snowy surprises.  Marginal yes but the best falls are often marginal in this country. 
GFS 6z has this for Monday morning.

Part of the Met news release:

....By Sunday most of the UK will be in the northerly airflow, with lower temperatures spreading further south overnight. Showers will fall increasingly as sleet and snow in the north, even to lower levels. Some showers further South and West, and perhaps a more persistent spell of rain overnight into Monday, could also turn to sleet and snow mainly over high ground such as the Brecon Beacons, Exmoor and Dartmoor...

But, will it snow in Carlisle? Or, even more unlikely: will it snow in Beccles?😁

DP looks a little high for early next week where the main band of precipitation is. Cold rain looks likely based on that. Could be some ice problems Monday night forwards

Different positioning again of the Sunday night/Monday low on the 12z.

This time further south and rushes it through quicker. Significant shift of the snow risk area to the SE. It does then re-circulate it in the North Sea to send it back into the UK, but only affects the east.

Again, a poor evolution (compared to those we saw yesterday) as we move toward FI, so a very transient coldish snap rather than anything to get excited about.

Don't worry, though, still plenty of time for it to change!

While that Sunday night low looks like bringing yet more strong in your face southerly gales to my neck of the woods, but other models are making less of it (unless the 12z ECM run show the same thing as GFS). It'll only going to be sloppy seconds marginal stuff anyway so I'm throwing in the towel with this upcoming chilly spell and just have to hope February offers better snow chances given the stratospheric profile for later on this month - and even that isn't a given.
