Ex-hurricane Helene arrives onto the scene today, bringing rain and wind - especially in the north and west. But also some very warm, tropical air.
The thing you'll notice early this week is how warm it feels despite an often strong and blustery wind. This is because ex-hurricane Helene will be 'pumping-up' tropical air from the South for a time as it crosses the Irish Sea tonight and Scotland tomorrow morning.
Most places begin the working week dry, but a weak front is giving a lot of cloud across the Midlands and Wales. It's thick enough to give a little drizzle in places, but this'll 'peter-out', with the North and West of Scotland and the West of Northern Ireland expected to see showers through the day. It's finer over North East England however with some sunshine and also towards the south coast.

During the day the cloud will break to let some warm sunshine come through especially over central southern and eastern parts. There'll also be sunny intervals elsewhere, and most parts stay dry, with basically a mixture of cloud and sunny spells today.
Winds are light in the East at the moment, but a southerly wind will freshen somewhat through the day to become strong in exposed parts of the West and South West later. It'll become warm even very warm particularly across parts the Midlands and in the East and South, where a quite summery afternoon looks on the cards. Although not so warm, the East and South of Scotland will also see good sunny spells with top temperatures over Scotland and Northern Ireland 13 to 15C in the West and 17 to 19C in the East. Across England and Wales 20 or 21C should be reached quite widely, with 23 to 25C expected in the East and South where you see the best of the sunshine.
It'll turn wet and windy after dark particularly in the West where the remnants of hurricane 'Helene' will bring severe gales, with gusts of 60 to 65mph expected in the West and across parts of northern England later in the night. Here together with Northern Ireland and the North and West of Scotland, there'll be showery bursts of rain some heavy, but elsewhere it'll continue mainly dry with broken skies in eastern areas into a fine, warm evening here. A southerly then South West wind will become very blustery everywhere, with the South West and Severn Estuary, in particular, getting a buffeting overnight.
Another thing you'll notice is how warm it is, with temperatures generally not falling below 16 to 18C over England and Wales and 13 to 15C across Scotland and Northern Ireland.
Tuesday begins wet and windy over Scotland, northern England and Northern Ireland, with a South West gale giving gusts to 60mph in exposed areas at first. This'll soon clear from Northern Ireland where a brief lull bringing sunny intervals will be followed by more rain later. Scotland sees a mix of sunny intervals and blustery showers once the rain has cleared through the morning. England and Wales become drier and brighter with sunny spells, especially in central and eastern areas, before more cloud and patchy rain move into the South and West of Wales and Cornwall later in the afternoon.
It'll remain quite blustery through the day, with a mostly fresh or strong South West wind continuing to give gales in the North and West. Despite this, another warm day for mid-September seems likely, with maximum temperatures of 13 to 18C in the North and 19 to 24C in the East and South.
Scotland, Northern Ireland, Wales and the North and West of England remain blustery during the evening and overnight with occasional rain or showers, in a fresh or strong South to South West wind that'll give further gusts to gale or severe gale force in the West and exposed areas. Elsewhere although not entirely settled and often cloudy with a few showers 'dotted' about, the emphasis should be on mainly dry weather especially in the East. Here too a southerly wind will be quite fresh and blustery in another very mild night, with minimum temperatures of 9 to 12C in the North and 13 to 16C in the South.
