Just thought I'd start a daily look at the GFS ensembles to see if there is anything pointing towards a downward trend as they start to near the period the longer term models are highlighting as the period of peak potential for a spell of very cold weather.
The London graph already showing a slight downward trend towards the end with around 3/15 members going for upper air temps near to the magical -10 mark. Thankfully the operational run overnight has very little support as it was a Horror!
