UK weather forecast: Sub-zero temperatures and possible snow with freezing cold Arctic blast on the way

The beginning of the week (February, 20) has seen unseasonably mild conditions with temperatures reaching highs of 16C in parts of the UK such as Suffolk, when temperatures usually average at 8C for this time of the year.

BBC meteorologist Helen Willets discussed the unusual temperatures in her forecast, saying the warm temperatures are set to continue for the beginning of the week due to Atlantic air making its way across the UK.
