extreme weather warning - some rain perhaps snow in January.

I recently watched an episode of 'UNDER THE DOME'  a town trapped under a dome...
the dome began to frost over and the citizenry started to panic - they were all freezing to death.
they mentioned the temperature... 2 degrees below zero?
what? two degrees ? These idiots were killing each other and panicking over two degrees below?
the Russian gulags in Siberia were 40 below, and the prisoners lasted for years with pitiful protection.
(watch a day in the life of Ivan Denisovitch)  - I realized the american writers must be Californian. Used to Lizard conditions.
it lasts a month... then it's rain for ten months. it's Britain... it's drab. buy some fleece jumpers.
