Beast from the East to blast the UK with SEVERE cold & HEAVY snowfall!

The UK looks set to see a return from an old friend that visited twice in March this year.

Model outputs are increasingly pointing to a bitterly cold Easterly.

The pattern will come about due to a change in the Arctic Oscillation. This change will see the AO turn negative. Opposed to a positive AO werby cold air tends to be bottled up at higher latitudes with a powerful jetstream going East to West we end up with a wavy jetstream which then allows cold air to plunge Southwards.

When the jetstream becomes buckled high pressure has a better chance of building at higher latitudes often referred to as Northern Blocking.

It is this scenario we are seeing from the weekend onwards. Initially cold air will not be to severe due to a lack of cold pooling to our East. However as time goes by this bitterly cold air will begin to make its march West through mainland Europe and eventually to UK shores. 

Many model outputs are showing what this could potentially mean with forecasts of European snow cover to be the most widespread it has been in November since the bitter winter of 2010!

Currently there are varying degrees of severity being modelled due to the timeframe concerned however the risk is increasing for conditions similar to those experienced earlier on this year.

So what could we expect?

Well should the Beast return the weather will be bitterly cold with frequent overnight frosts, Biting windchill and snowfall possible just about anywhere.

Beyond this a continuation of a negative AO will see the potential for cold weather persisting well into December.

White Christmas anyone?
