I'm sure the same could be said of us 80s kids by those who were around in the 60s, mind you. 😂



I remember several occasions, when rain fronts moved through , sudden drop in temps, heavy wet snow, then snow, then clearing to heavy showers with skies darkening from the north all the time with rain/snow showers and sunshine.

Thats when northerlies nearly always delivered , even all the way down south.

Merger is quite clear here. Note the outflow channel (red arrow); when the LP hits that we get rapid intensification. There is some genuine potential here for a quite significant snow event if  
the LP hits this upper level outflow channel over the UK

Yes - you are sooo right here. The 60s were so very snowy at times. I remember being at school in 1969, and whenever it precipitated it was snow, even when it didn’t settle, and wow, when it did - it was deep, and this was in the Deep South - Nuthurst, West Sussex.

GFS 06Z OP looks like delivering a bit of love in time for Valentines Day ;)
One option, one run, likely all gone by the 12Z - but (huge caveat) the UKMO long range and EC46 anomalies have been pointing to something akin to a Scandy high for a few days now.

Something for everyone seemingly on the 6z GFS op run.

Snow in parts north as cold air pushes south.
LP running across the Midlands with snow on the northern flank.
Less cold/chilly HP interlude followed by a strong cold easterly. 

Part 1 is IMO very likely and essentially in the semi reliable.
Part 2 is uncertain as it depends on LP track. I think it's more likely that will be over the UK somewhere this time round as different setup to the Jan LP tease but as others have said it really depends on how the LP deepens/interacts with the jet and it's too far out to be confident in that. Somewhere from the M4 to southern Scotland could see snow as it stands I think but I'd punt it as somewhere between northern England and Wales/Midlands. 
Part 3, will wait for the ens and subsequent runs but a very low chance as it stands. It shows what can happen though and with some of the background drivers allegedly being favourable and Easterlies a little easier to come by in mid to late Feb as the jet dies down it's something to keep an eye on.

Yep an old school 80s classic easterly on the 6z. Outside bet atm but mid/ late February looking like it could be the best of this winter at least.

I won't elaborate too much as there is a separate thread for nostalgic discussions.  (I don't think I would assess the snowiness of the 50's and 60's as being better cold event wise than the late 70's and 80's. Especially if you take out out the unbelievable anomaly of 1963 winter out of the equation. I think it is probably easier to say this century now, as being a totally different kettle of fish. Genuine blizzards, often forgotten because they were short lived, were far more common then.) 
The second half of February is starting to look promising. February the 10th looks like a key date when it may or may not start to happen. It has a look of longevity about it compared to the January cold snap.

Missing the S.E. corner completely, the area that was amongst the worst hit by memorable snow events of the sixties, to nineties.

The cold period of the 50s to late 80s seem to curiously coincide with peak nuclear bomb testing around the world.

possibly, volcanoes as well, mount st helens etc

however, recently, no matter how much Iceland blows up volcanic wise, it has no effect on UK

That unpronounceable volcano in iceland that went up in early 2010 was followed by one of the coldest December's on record. I think this might be more than just mere coincidence.
