It will become very warm for many in Sussex but will feel cooler in coastal districts. Temperatures will peak at 24 degrees Celsius.
Met Office meteorologist Aidan McGivern said Saturday 'could be the warmest day of the year so far, across the UK'.
Cloud and sporadic rain and showers are likely to spread northeast during the evening. Some of this will be on the heavy side, 'with a risk of thunder'. Temperatures will drop as low as seven degrees Celsius.
The sun is set to disappear on Sunday.
The Met Office predicts a cloudy day, with outbreaks of rain and showers at first, 'perhaps with thunder'.
These conditions should gradually move away to the north, 'leaving a drier and warmer afternoon'. Albeit quite breezy, the maximum temperature will be 25 degrees Celsius.
