I was just about to post on that matter myself. Would be seriously nasty if that happened but it's 6 days out. But would a depression normally deepen explosively like that when actually over the UK? Don't they usually deepen rapidly in the 1-2 days prior to hitting us?

They normally do yes - but all things are possible. Couple of models now going down the explosive deepening route over/very near the UK.

Your quote right John. Also, I noticed this modelled yesterday as well. It’s one to watch, and if it came as progged would be seriously worrying.

I've increased the range of UKV charts available on TWO.

https://www.theweatheroutlook.com/twodata/ukv.aspx

Snow depth, precipitation type, fog fraction, dew point, relative humidity and wind streamlines can now be viewed. I'll probably make some formatting changes to the precip type chart in the near future.
