It's Notting Hill Carnival weekend and many west Londoners will be praying for sunshine to round off the glorious summer we've had.

Friday's (August 24) torrential downpours in parts of London did not get the Bank Holiday off to a promising start but Saturday (August 25) looks to be slightly better.

Met Office forecasters predict Saturday to start cool with lows of 14C. Sunshine is expected throughout the morning but could be disrupted by rain showers in throughout the afternoon. Temperatures could reach highs of 20C.

Saturday night is forecast to be clear and dry with temperatures plummeting to 5C in some parts.

Heavy rain is expected from midday on Sunday with strong winds to boot. Those heading to family day at carnival may want to wrap up and wear a waterproof as temperatures could dip to 15C.

Bank Holiday Monday looks likely to remain dry but overcast with temperatures peaking at 19C.

Looking ahead to early next week a Met Office forecaster said: "Often dry on Monday and Tuesday with pleasant sunshine, and isolated light showers on Monday. Sometimes bright on Wednesday, but with cloud thickening bringing possible thundery rain."

Heavy rain is expected on Sunday (August 26)
