The final day of September is looking mostly fine for many regions thanks to a ridge of high pressure but low pressure out over the Atlantic is knocking on the door and will be sending weather fronts into western parts of the UK and Ireland today with these fronts then set to affect many regions at some point over the weekend.

It's a fine and chilly start for most places with temperatures this morning low enough to bring a touch of grass frost across rural parts of northern Britain. There will be plenty of sunshine around though to help lift temperatures this morning and for much of north-eastern Scotland, southern and south-eastern England it will be a mostly fine and dry day with further spells of sunshine.

Meanwhile, for much of Ireland and Northern Ireland cloud is already thickening up from the west with outbreaks of rain moving in from the southwest and this rain will extend further north and east as we go through the day, some of that rain making its way across into parts of Wales, northwest England and southwest Scotland to bring a rather damp end to the day in these regions.

Maximum temperatures today will range from a rather cool 14°C or 15°C in the wetter areas to 19°C or 20°C towards brighter parts of the southeast so feeling pleasant in the sunshine here.

After a wet evening across much of Scotland, northern England and parts of Wales, that rain will tend to ease for a time before another pulse of more persistent rain pushes in from the southwest into parts of Wales, central and northern England. It remains mostly dry towards the southeast of England, and blustery showers will feed into north-western regions. Tomorrow sees a weakening band of rain moving slowly southeast across England and Wales with showers in the north and west, but southeast England may well again stay mainly dry.
