i wouldnt worry about what the met office said in their forecast as some people have been! they arent calling for a milder than average winter if you read their forecast, what they are saying is that this winter will be up to 2°c warmer than last year, last year which was 2-3°c colder than average in places which means that a cold winter is still on the cards, and i dont think the MO dont have a clue themselves!
personally i think it will be almost impossible to have a mild winter this year. i know it probably wont be as cold as last winter but i feel the atlantic has lost its 'energy' already and we wont be seeing much in the way of westerlies in the coming months.
other factors that lead me to believe this are as folows:
solar activity i check this daily, and the current solar activity (sunspot number) is still very low, 34 today but take into account it can reach 250 during times of high activity.
there has been a huge increase in volcanic activity lately which i know wont effect the recent weather patterns, but may cause cooling into next year.
as for the current La Nina, i cant find any link between ENSO and the winters of europe temperature wise. (if someone can please let me know)
the north atlantic drift in particular is still in a terrible state (i have a chart from last year and its quite shocking if you compare it to this years, ill upload them both for you to see when i find it!)
cold weather has arrived much earlier than last year, although this doesnt have much of a link to the coming winter (mild november last year!), the last time winter arrived this early was 2008 which we all know was also very cold!
if anyone has any thoughts on this please share them
