A plume of "tropical air" is expected to sweep across parts of the UK over the weekend, bringing unseasonably mild temperatures, says BBC Weather.
Forecaster Steve Cleaton said: "Through the weekend, increasingly mild air of tropical origin will be steered across the UK by westerly winds."
Temperatures are expected to peak on Monday, with highs of 17C in some parts.
