That wales online report of Exacta Weather's prediction doesnt seem to be very exacta...its more like the Mirrors inaccurate report of plunging to -5 and widespread snow and the annual Express prediction of the worst winter in 50 years...No doubt one year they might get it right if they say it often enough.
All of the mid range forecasts i read from all the global weather agencies have been predicting wet windy and unsettled weather up to Christmas for the UK which is what we've had so far.
We usually get frosty periods in November and December so thats nothing unusual but theres no significant threat of snow as yet or significant frost.
Over the pond in the US theyve had unusual early snow and record snowfalls in the Rockies and MidWest while California once again burns.
Unless the jetstream moves suddenly north or we get another disturbance of the polar vortex (a belt of high speed winds that circle the poles) and drags cold air down over us we will likely continue with the unsettled wet weather.
There are some signs the polar vortex is being distorted but nothing to suggest a massive change in weather patterns as yet. Up to Nov 19 its looking like more of the same - cool unsettled.
