Brits are set for freezing temperatures to return as the week progresses with snow flurries and lows of -2C.
It was very mild on Monday with the mercury rising to 16C in Suffolk and it was quite widely in the low teens which is well above the average for the time of year.
But it will start to get colder and there will be a definite icy feel by the end of the week with the windchill factor included.
