A Warm January in Bulgaria

Temperatures in some parts of Bulgaria hit 19.5c yesterday (in areas such as Veliko Turnovo).This is very, very odd. It should be freezing, with lots of snow at this time of year.The prediction was for a cold winter, but we only have 6 weeks left till March.One can only contrast it with the UK, which appeared to be having a very Balkan winter.Some say global warming, some say gulf stream but in 7 years here I have never experienced weather like this.
