Very much a northwest/southeast split in the weather to start the working week in terms of temperatures and humidity. For northern parts of the British Isles it's a cool and fresh start with temperatures overnight having dropped down into single figures whilst towards southern counties of England it's a rather cloudy and muggy start with temperatures in the mid-high teens.
Northern and north-eastern regions of the UK will remain mostly dry with sunny spells today and just the odd shower but temperatures won't do much better than the mid-high teens. Meanwhile, for most other regions there will be a fair amount of cloud around as showery outbreaks of rain push in from the west. Not everyone will see the showers, but where they do occur they could turn heavy and prolonged for some and by this afternoon there is a risk of some thunder in places too. Outside of the showers and there will be some warm bright or sunny spells with temperatures towards East Anglia and southeast England reaching highs of 23°C to 25°C.
Most of the showers will clear away to the east tonight but some showery outbreaks will continue in the west. It will be a rather warm night for many, especially in the south, and this takes us into another very warm day tomorrow across the south-eastern quarter of the UK. Once again it will be the north and west that sees the cooler conditions with more cloud and some showery rain moving up from the southwest at times.
