weather bombs and Christmas dinner!

It was very cold when I got up this morning and it took a while to defrost the car before setting off for work. Other than this the weather was unremarkable in this part of the country. In other parts of the country apparently the UK experienced a 'weather bomb.'
I know now that this involves severe storms but the puzzling thing for me is I have never heard this term used to describe weather before.
Have I just not been listening to all the other forecasts warning us of such an event or have the weather people just invented the term?
Another significant occurrence today was the school Christmas dinner which was delicious.
I love roast potatoes, especially when they are cooked by anyone other than me!
I arrived home after work today and took Ollie out for a walk. Many houses on my estate are bedecked with flashing Christmas lights. When I arrived back at my house there was a Christmas float doing the rounds, broadcasting Christmas songs. Santa was waving  and people were rattling charity buckets.
Christmas feels well and truly around the very next corner!
