Well you've heard it all already - I'm pretty confident that the big change in Atlantic weather that I mentioned last week is now imminent (caused initially by the collapse of an intense cold air dome over Canada last week).
Expect severe gales in the run-up to Christmas, with (brief) snow Wednesday night/Thursday; otherwise torrential rain, violent hail squalls, storm force gusts, thunder and lightning too. Keep alert too to closer short-term warnings (from reputable providers of course e.g. The Met Office) - some of the individual storms could be very potent, and blow up (and out) within less than 24hrs.
'Tis the season...
Podcast from the Met Office today:
