I see 21 snow rows for Wednesday. This has been a fairly consistent signal yet nobody is talking about it nor is it showing up in the forecasts. So what's going on? Is there any chance of snow this week and if not, why are so many snow rows showing up?

I think there's decent confidence for high pressure to our west to become influential over the next few days, bringing some cool-to-coldish 850's, but nothing that will deliver lying snow away from altitude. The high will then semi-topple, introducing some milder air. Confidence diminishes after this - most favoured evolution IMO is for the high to plonk its derrier over ol' Blighty, but it may position/ridge NE'wards.

All pretty insipid and not really inspiring, mind you we might get to register a few frosts. Whoppee, Iโ€™m so excited I could crush a grape.
In the meantime quite a distinct possibility of cold shots into Southern Europe, some output even suggesting as far south as North Africa. Whatโ€™s the more likely- real cold in UK or The Med and North Africa? I know where my money is going.....

Thanks for the replies, Saint and Rob K.


Probably nothing to get too excited about so. Just goes to show how unreliable those snow rows are, if taken in isolation.

Finely balanced will that waft inflate the high to the north


 


Not this time looks to be a milder run

Today has not been a good one for us dreamers with a tangible reduction in the already low probability of such an elusive set-up, as the current GFS run demonstrates.

Looks like coldest temperatures will stay on the other side of the North Sea/Channel next week... It will be a very close run thing though.

Now I know why:


Another PV Arctic plunge for N. America with daytime maxes of -12c over NEW York City if this verifies.


Thanks to the NW Canadian Block and Alaskan high it's buggered things up for us, this will push cold air into the NE of America/Canada and blast up the jet and flattern any ridge over Greenland! We will never get a Greenland, Iceland or Svalbard or Northern Scandinavian HP block with charts like this. There is northern blocking but once again it's right over North western Canada & Alaska ! So the wrong place yet again!!!

The ensemble hasn't changed that much. The mean is pulled up a bit by a mild cluster around the 8th, but it's basically meteorological linguine from the 5th.

Highly variable outlook in the GFS Ens: the control is up and down almost throughout the run.

Some of the Ps are more continuous but there's a lot of undulation, and therefore a lot of capacity for changes, generally.

Darren's analogy a few days ago about the rock on the see saw is still applicable


GFS seems unable to disrupt the northern jet enough with pulses of WAA. UKMO looks like it is about to make it, but its very finely balance. THe METO outlook earlier does suggest Exeter seem to think a block will develop

The third pulse is still likely to happen, now down to 6 days out, but we're no further towards knowing whether it'll be enough to tip the balance [towards a cold outbreak] or not.

ECM looking pretty uninspiring, it must be said. A very positive NAO pattern setting up.

The period beginning early next week is FI right now as far as I'm concerned, and I suspect it might be Wednesday or Thursday at the earliest before we get a firmer idea of what happens after next weekend. The models seem to be all over the place big time right now. Just look at the end of the ECM 12z op and note the difference between the way it ends and the way the 00z run ended.


They don't seem to have a clue right now.

The atlantic has been active this winter, but it has not dominated our weather in quite the same way that has been the case in many winters in the last 30 years.

I think its a pretty good run definitely a shift to the ukmo. At 168 it could go either way expect some very good ensembles .
