If I'm right, and the US folks refer to sub-zero Fahrenheit, I would be happy if I never had to experience anything anywhere near that severe...Frostbite after only 30 minutes' exposure? No thanks!

Its always Fahrenheit in the states. For instance in the ski resort of Stowe in New England over the next few days the max temp is -4F and lowest is -16F then add on windchill!!!

The gfs still on course this morning for the major east coast storm to impact NE Canada (still some doubt on precise track), and a good illustration of the accompanying amplification to the east that  will affect the UK next week.

The ecm has it 941mb

The 12 gfs has the storm 952mb and the Bermuda high surging north and north east to the east of the upper trough which is key to the evolution of the pattern over the UK next weekend.

This can get a tad complicated

-16oF is starting to get cold. Lowest I experience was air temp of -42oC (-43.6oF) The body doesnt work very well even if your not directly in the cold.Luckily it only lasted 2 days.
