Heavy rain and wet, grey autumn weather are on the way to west London.

Low cloud, fog and murky skies will move in to cover the capital on Wednesday (September 27) afternoon with the rain forecast to arrive at around 7pm.

Drivers are warned of poor driving condition as rains and poor visibility are set to last well into Thursday (September 28) morning.

Wednesday's "hazy sunshine" and warm outlook will not last but as the evening arrives the weather will change dramatically, according to the Met Office.


Met Office Spokesman Emma Sharples said: "We’ve got a front coming in from the Atlantic - warm air and cold air meeting - producing clouds and rain from that.

"That rain is already edging into Cornwall at the moment [midday] and that band of rain is going to spread further eastwards as we go through the day.

"For the area, it will probably be well into the evening before you see any rain."


Stills taken from the Met Office's live forecast show how the rain is expected to develop into the evening.

The gentle blue rain patches slowly give way to more severe yellow and red patches, which denote increasingly heavy downpours.


"There will be a few hours of rain, rain through the night and rain through the early hours of the morning before it starts to clear away,” Ms Sharples added.

Anyone travelling on Wednesday night into Thursday morning are advised to allow extra time for travel, especially if driving in adverse weather conditions.


But there is still hope for Thursday though when the rain clears and temperatures rise again.

The Met Office is forecasting "sunny spells with temperatures in the high teens and maybe into the 20s".

The forecaster added while there would be no "stormy" or "extreme" weather, it was a significant and steady band of rain.

"There’s nothing particularly stormy there," said Ms Sharples. "It’s just a band of rain spreading from west to east.

"It’s a steady period of rain, perhaps enough to give you 15mm to 20mm, mostly overnight, so most people will be inside anyway.

"It’s a fairly standard amount of rain for a weather front that’s coming through in autumn."
