Pretty much as is. Look at those high snow % for Thursday, shame, all we need is a precip spike!

I assume you mean too low?


 


That would explain why GFS has consistently modelled snow from the front on Wednesday night for the south while none of the professional forecasts mention anything other than rain, I guess. The only mention of snow down here is in "wintry showers" after the front pushes through, which we all know don't actually exist in the south from a northerly. (And in any case the actual output just says rain showers and 5C on Thursday and Friday here...)

Though the flow Wednesday night is actually more westerly than northerly so the usual 'rules' don't apply in terms of having precipitation in the first place.


I suspect a real mix of rain, sleet and snow, the latter favoured toward dawn as the flow turns more to the NW, though precipitation fading out by that time away from the coasts.

The spread really begins on Tuesday, and the op is one of a definite cold cluster - still in the minority, but there is support.

Sorry but saying it is very unlikely to snow in the South in a Northerly set-up is being realistic, when have Southern areas ever done well out of a Northerly? The 2004 Thundersnow event is all I can remember.


Scotland, NI and parts of NW England look like seeing some snow but that apart dry, sunny and a cold wind looks to be the order of the day. smile

It was pointed out to me this morning that the 850hPa level, due to the low pressure, is actually quite a bit lower than maybe you'd expect, which will help.

Temps do creep up during the day, so I think the showers will turn back to rain by lunchtime on Thursday, but conditions could well turn favourable again overnight into Friday morning.


A messy setup, but I currently think Thursday morning and Friday morning rush hours, could be potentially snowy.


Needless to say, Buxton is going to get completely buried, and the raw data on the MetO app for that Derbyshire town is mouth watering.

What are people's thoughts on the chances for the East? To my untrained eye it seems like there are 2 lows being modelled to scoot down the E Coast - Sat and Tues. Sat is due to bring rain/sleet to lower levels, but Tues has snow.. I'm assuming this is because the air feed then is much colder, whereas on Sat it is not cold enough for snow.

The south is a different matter, the airmass is just too moderated by the time you get south of Yorkshire, so here snow showers restricted to the west in the absense of any feature. 


2023/2024 Snow days (approx 850hpa temp):

18/12 (-1), 06/03 (-6), 08/03 (-8), 09/03 (-6), 10/03 (-8), 11/03 (-5), 14/03 (-6)

Based on the 6z GFS run, thats my take on the two lows as well.  Doesn't look cold enough on Saturday but does on Tuesday. However Saturday is still 5 days away so there will probably be a lot of changes before then. Following Tuesday is just too far away to take seriously right now though worth keeping an eye on.  Not checked the 6Z ensembles yet.

All in all it's looking OK, and our best shot so far. GFS/ECM could obviously improve by removing the that milder blip on Friday/Saturday as the low sinks over the UK, but it'll do for now as I can't see how we avoid that in order to get the colder feed to filter south behind it.

Re Solar Cycles inaccurate post above - apart from the likes of Tallyho, who never listens or learns, I haven't really seen anyone in the south moaning about what is or is not in store. What I have seen is a lot of sensible and reasoned discussion overall on here. The reason I quoted this post is because there are some dreadful benchmark charts out there, and the GFS Precip charts are right up there in the misleading stakes on many occasions. As has been pointed out zillions of times.

I guess it easy to write that from a cold and snowy Norway isn't it Mike.


I see very little change this morning with cold and wintry weather on offer from Thursday into to next week with a risk of snow in places before any breakdown.


Detail is impossible to try and pin down.

You are correct in that snow will fall in places and overall, it will be a cold and wintry picture but when all said and done, cold PM air, I feel, will not deliver too much in the way of settling, disruptive snow for the majority in the S. I could be wrong, of course... and will acknowledge my failings if that should prove the case :-)

Am I in a minority thinking that set is an upgrade to the 00Z set? Discounting the control, the OP takes several members on a ride down towards the -10 line that hardly any crossed last run.
There's plenty to keep the unbiased enthusiast engaged in the next week IMO.

Days have also been fairly chilly at times and we still have a month of Winter to run . Of course it all depends on what one's expectations are from the off , mine weren't that high and I certainly didn't get sucked into this OPI scam . Hopefully the 7 days or so will give us something to talk about

The reason why I may have appeared negative is simply because it appears as things move into the reliable time frame, and almost inevitably, small shortwaves are being picked up which are cutting off the N'ly flow, at times, to some degree. This can bode well for heavy snow in places but I would have to say on the N and E side. NYM, Derbyshire Peaks, Pennines and Highland Scotland all looking good for snow.


I think the 06z ENS are perhaps marginally better.

We just need the precipitation
