I think what you need to take from this is that snow precipitation will be almost guaranteed to fall where the upper air temperature is below -5oC,
for definate assurance look at around -7oC for snow at sea level. Although its good to look at the 2m temp, i find its best to view the 850hpa temps.
The ECM is showing approx -10oc uppers, along with the JMA. GFS is struggling to battle out the Atlantic influence and we have -10oC uppers right on
the east coast of the UK.
I think once this evenings models come out, we will be a step closer to seeing a definative in the MSM.
What we need is GFS to follow suit, which i believe it will but it may play around with Battlefield Britain for the next 24 hours yet.
For ideas on potential snow events, i would say look at around 96 - 144 hours away.
p.s. i too am amatuer at this and forecast all my own weather...i very rarely watch the MSM weather
