Define "deep cold".
-18 C in Scotland is pretty darn cold. Oh wait Scotland does not
really exist, apologies to Alex Jr......

Don't get me started lol.
With an average December temperature of +0.0ºC in this part of central
lowlands, frost every day for three weeks and total snow cover largely
greater than 6 inches for over 2 weeks and minor roads with several inches
of ice this has already been an unquestionably and definitive VERY cold
period, nevermind snap or spell for at least a part of the UK. The squib was
loud indeed, we'll need to wait though in order to see if it was Dynamite or
Nuclear. Perhaps the shockwaves have yet to reach the Watford gap!
