Ensembles have trended downwards. Repeated extreme cold shots coming off the Eastern Seaboard must be cooling the atlantic sufficient enough to allow the sub -5c 850Hpa isotherm to reach the UK ..the next bout of strong and zonal westerlies is now sufficiently cool enough to bring a little sleetiness to the south at times based on this seemingly ?

The GEFS has trended cooler but in reality, this is even more depressing as it means it will just be more miserable with the rain. Snow will fall at times on northern hills and at times, on higher ground from say Midlands northwards but for the vast majority of us lowlanders/city dwellers, anything from the W will fall as rain... imho.
Also, any brief encroachment of continental air over the SE later this week , as per ensembles, will be very brief. Any transitional sleet/wet flakes over any higher parts in the SE will be pointless. I know many are eager to at least claim some snowflakes but when it comes to catching some magic by viewing a lampost, we have to ask ourselves, why??!!!! I'd rather grab an extra 40 winks at my age now
