Cloud will thicken up from the north west this evening with some light patchy rain arriving in the South through the second half of the night. It will gradually brighten up from the west tomorrow morning, then dry and feeling warm with long bright spells tomorrow afternoon.
Tonight will start dry in Kent and Sussex but it'll become cloudier with some showers and heavy bursts of rain for the second half of the night. Potentially some thunder too. Tomorrow will start grey with some rain around but then it will gradually brighten up in the afternoon and become warmer. But there will still be the risk of a shower.
