Its not from any particular website. Its a combination of things I've learned about over a while.
Sudden stratospheric warmings lead to blocking a few weeks later, which if in the right place lead to northerly winds and cold. Blocking is hard to shift, hence the forecast for extended cold.
The summer forecast is based on "analogues" which are representations of what happened in previous similar years, in this case assuming that the El Nino turns into a La Nina quite quickly. These years tend to have very poor summers, which may start ok but usually feature mainly low pressure, leading to cool and wet conditions. If we are lucky the La Nina will be slower to develop or not develop at all, and this can give a much better summer here, but the models are all going for La Nina. There is also the "cold blob" in the atlantic, which is even stronger than last year - and last year this same cold blob was blamed for the cool summer.
The winter forecast is based on the things that I have seen in previous years winter forecasts. Some of these are already certainties - the sun is heading into solar minimum soon, having been in a (weak) solar maximum for the past few years. Low solar activity leads to higher chances of blocking and cold northerly or easterly winds in winter. We are also heading into an easterly phase of the "QBO" which tends to weaken the prevailing westerly winds which bring the sort of weather we have had in the past 2 winters - warm, wet and windy. We have been in a westerly QBO this winter. Then there is the La Nina to contend with, which may favour the cooler winter scenario, if it develops as expected. There are other factors that are important too, and it is too early to know how they will work out.
Long range forecasting (beyond 5 days) is exceptionally tricky and I hope I've misunderstood the signs I've seen.A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP. - Leonard Nimoy

I haven't read all the responses but this smacks to me of the sensationalism of the red tops.
We are all entering the 'snow age'
Balls, it's just another year with another season of unknown weather. As to entering the next ice age, I have more chance of winning the lottery than this weather pattern actually happening.
