Went to bed last night having seen the BBC being quite bullish about battleground snow in the south but this morning's charts suggest the necessary cold air will stay further east and there's a push for mildness from the south with HP stronger over France.
GFS in the longer term shows depressions from the Atlantic moving to/across the UK on rather more southerly tracks than yesterday, and being deflected southwards e.g. Sat 30th (a quick pass)Tue 2nd - Thu 4th (hangs around). In the following week (Wed 10th) a rather deeper LP manages to cross the UK to develop a trough from mid-Atlantic to Baltic.
GEFS for the S gradually becoming cooler to Sun 7th though not far from norm with plenty of rain but a very wide range of runs thereafter. As you go further N and into Scotland there is a colder and drier spell to start with before coming back to norm with rain from about Tue 2nd. Just as chaotic after the 7th, though
ECM also runs with the theme of continuing LP over the UK but keeps the main centre further NW with troughs extending in the direction of Britain
