UK weather forecasters detail temperature change of -6C as westerly wind bites
The mercury will drop by at least 6C today from yesterday as Brits finally get a respite from the sweltering heat.
Rain and thunderstorms are also expected in some regions, including the Northwest of England, this afternoon as a band of low pressure creeps in from the west. This will also lead to gusts of up to 50mph along the coasts of south Wales and Somerset and Devon today.
The mercury yesterday reached 28C in Hull, while it hit 26C near Bedford, two of the warmest places in the UK on Monday. Just 20C is anticipated in Bedford today - a 6C drop in 24 hours - and only 18C is expected in Hull, a huge 10C plunge on Monday's peak.
Forecasters at Ventusky, which uses data from the the US' National Oceanic and Atmospheric Administration (NOAA), the East of England is likely to be the warmest region today with 22C expected across Norfolk and Suffolk, though this is far cooler than the weekend's furnace. A sweltering 33C was recorded in Cardiff on Saturday, according to the Met Office.
More than 25mm of rain is expected to lash across Cumbria and parts of Lancashire this morning. It will then move southeast but fall as showers across all of Yorkshire, and the Midlands throughout the afternoon.
But forecasters believe the weather will turn thundery in various places, notably across Greater Manchester, throughout this evening. Overnight, East Yorkshire and Humberside will experience the heaviest of the storms, before the miserable weather moves further east over the North Sea.
It will be quite the contrast - and relief - to recent scorchers. In relation to today's picture, the Met Office website reads: "A band of rain will move east through the day, followed by heavy scattered showers in the northwest. Windy for many, particularly across the south and west. Feeling fresh."
The sequence begins an unsettled ending to July. The Met Office's long-range forecast, concerning the period up to Monday July 28, says it will be "wet and, in places, windy". It adds: "Unsettled, wet and in places windy weather is likely this coming weekend, followed by something a bit more mixed. Any more settled spells could persist for a few days at a time and are likely to be accompanied by plenty of sunshine, but interspersed with these will be cloudier, more unsettled intervals which will bring some showers or longer spells of persistent rainfall."
The heatwave has led to concerns around heat rash and sunburn. However, when one mum shared online an alternative treatment for sunburn, social media users were sceptical the approach would work over NHS ' official suggestions.

Heavy showers could cause some localised flooding and transport disruption. The Met Office say there is also a small chance of fast-flowing or deep floodwater causing 'a danger to life.' The environment agency SEPA has 15 flood alerts in place, all the way from Aberdeenshire in the north to Dumfries and Galloway in the south. Several areas across Scotland are covered by the yellow thunderstorms warning. In the north of the country, Aberdeenshire, Moray and Highland areas will be affected. Places affected in central Scotland include Angus, Clackmannanshire, Dundee, Falkirk, Fife, Perth and Kinross, and Stirling. A large number of areas in Strathclyde are covered by the warning, these include Argyll and Bute, East Ayrshire, East Dunbartonshire, East Renfrewshire, Glasgow, Inverclyde, North Ayrshire, North Lanarkshire, Renfrewshire, South Ayrshire, South Lanarkshire, and West Dunbartonshire. In the south west and Lothians, Dumfries and Galloway, East Lothian, Edinburgh, Midlothian Council, Scottish Borders, and West Lothian will be affected. Simon Partridge, a forecaster at the Met Office said: "We could see some locally heavy downpours, 20 to 40mm of rain is possible in a couple of hours. Moment 'possible tornado' whirls near busy Irish town with more 'thundery downpours' TODAY amid 'unsettled' conditions "That is potentially up to around half a month's worth of rain in a couple of hours in some places. "You will see quite a lot of water on the roads and difficult driving conditions. "Hopefully nothing more significant than that, it certainly won't be an issue for any of the rivers because they are quite low." The atmosphere is being warmed by high temperatures in England, pushing a series of weather systems northwards. What you should do during thunderstorms Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit. Prepare to protect your property and people from injury. Before gusty winds arrive, check to ensure moveable objects or temporary structures are well secured. Items include; bins, garden furniture, trampolines, tents, gazebos, sheds, and fences. Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It's easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you find yourself outside and hear thunder, protect yourself by finding a safe enclosed shelter (such as a car). Do not shelter under or near trees, or other structures which may be struck by lightning. If you are on an elevated area move to lower ground. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area. Source: Met Office Low pressure and humid, moist air across the country will cause the heavy, thundery showers, but even within the warning areas some places will stay dry, the Met Office said. Forecasters say buildings could be damaged by floodwater, and there is a slight chance that power cuts could occur. "There is a good chance of seeing some lightning and some hail, with some gusty winds as well," Mr Partridge said. There is also an amber warning for rain in parts of Northern Ireland. The country records an average of 89mm of rain in July, meaning more than half a month's rainfall could hit Northern Ireland in less than a day. The rest of the week is set to be changeable, with showers likely on Tuesday and thundery downpours possible on Wednesday. Temperatures this week will be around average for the time of year, the national weather service said. The wet weather comes after a dry and hot spring and three heatwaves so far this summer which left four regions of England in drought.

Flooding across parts of Ireland after heavy rain
There were reports of localised flooding across parts of the island following a series of weather alerts on Sunday, with the unseasonably high rainfall into the start of the week. A status orange rain warning for Dublin, Louth, Meath and Wicklow came into effect from midnight and expires at 2pm on Monday. Warning Updates Status Orange Rain & thunderstorm warning for Dublin, Louth, Meath & Wicklow Valid: 00:00 21/07/25 to 14:00 21/07/25 Status Yellow Rain warning for Kildare & MonaghanValid: 00:00 21/07/25 to 14:00 21/07/25 Stay safe and updated⚠️ — Met Éireann (@MetEireann) July 20, 2025 Irish national forecasting agency Met Eireann said there would be persistent and heavy rain with a chance of thunderstorms. Meanwhile, Kildare is under a yellow-level rain warning for the same period. The warnings followed other alerts about thunderstorms in the east of the country and increased rain in the south-west. Met Eireann warned that the weather would bring widespread surface flooding, very difficult travelling conditions, lightning damage and very poor visibility in the worst-affected areas. The Met Office also issued a yellow-level rain warning for the east coast of Northern Ireland. Heavy rain over Northern Ireland on Monday morning with flooding possible in places. Some rain in parts of Scotland, northwest England and Wales too ⚠️ Heavy thundery downpours across southeast England and these developing in other eastern areas through the morning ⛈️ — Met Office (@metoffice) July 20, 2025 The region was expected to experience some of the worst of a heavy spell of rainfall until 6pm Monday. Forecasters predict affected areas could see half a month's worth of rain in less than a day after a warning was put in place for Antrim, Armagh and Down for the 24 hours from 6pm on Sunday. A more intense amber-level warning temporarily put in place overnight has since been lifted. The Met Office warned there is a risk that homes and businesses could be flooded. The expected rainfall carries a risk of flooding, power cuts and dangerous driving conditions. Forecasters also warn there is a small chance that some communities could be cut off by flooded roads while fast-flowing or deep floodwater could pose a danger to life. Simon Partridge, a forecaster with the UK Met Office, said: 'It looks like Northern Ireland is the place where we could see the most rainfall and certainly the most impactful rainfall. 'They could see 50 to 75mm of rain within 12 to 18 hours.' The region records an average of 89mm of rain in July, meaning more than half a month's rainfall could hit Northern Ireland in less than a day. A yellow-level thunderstorm warning was in place for the western half of Northern Ireland between midday and 8pm on Sunday. Flooding was already affecting routes in Fermanagh on Sunday evening, with the Marble Arch Road, Florencecourt, and Sligo Road, Enniskillen, both described as impassable by police. A PSNI spokeswoman said: 'Please take care when travelling, slow down, and exercise caution on affected roads.'

Thunderstorms to batter the UK with flash flooding, hail, lightning and half a month's worth of rain today (but there'll still be a hosepipe ban)
Most of Britain was on thunderstorm watch today as up to half a month's rain could fall with forecasters warning summer storms are set to bring flash flooding. England and Scotland could see up to 40mm (1.6in) of rain in just two hours, while Northern Ireland will be worst hit where 75mm (3in) may accumulate in 18 hours. It comes as the third major hosepipe ban of summer began today, with Southern Water activating restrictions for households in Hampshire and the Isle of Wight. This follows a ban from South East Water in Kent and Sussex since last Friday, and in the Yorkshire Water area since July 11. A fourth ban from Thames Water begins tomorrow in Oxfordshire, Gloucestershire, most of Wiltshire and parts of Berkshire. Despite three consecutive days of heavy rain, forecasters say this will do little to replenish groundwater reserves because it is running off very dry surfaces too fast to penetrate – and therefore the downpours are not enough to lift hosepipe bans. Yorkshire Water confirmed its restrictions will only be lifted when 'reservoir and groundwater levels return to where we need them to be', adding that the region would require 'a few months of wet weather rather than intermittent rainfall'. Parts of the UK will experience heavy, thundery downpours today, with an amber weather warning for rain in place until 8am for the east of Northern Ireland. Met Office forecaster Simon Partridge, said: 'It looks like Northern Ireland is the place where we could see the most rainfall and certainly the most impactful rainfall. 'They could see 50 to 75mm of rain within 12 to 18 hours.' The country records an average of 89mm of rain in July, meaning more than half a month's rainfall could hit Northern Ireland in less than a day. Forecasters have warned of a risk of flash flooding in County Antrim, Armagh and Down as the heavy showers are set to batter the country. Meanwhile, parts of England and Scotland could see 20mm to 40mm of rain in just two hours today. From 3am until 9pm today, the South and East of England are covered by a yellow thunderstorm warning. By 11am the same warning will be in place for the Midlands, northern England and Scotland. More than 11 flood alerts remain active in England and 15 in Scotland. Where there is flooding or lightning, the Met Office has warned of a chance of delays and some cancellations to trains and buses. There is also a small chance of power cuts and of fast-flowing or deep floodwater causing danger to life. 'We could see some locally heavy downpours, 20 to 40mm of rain is possible in a couple of hours,' Mr Partridge said. 'That is potentially up to around half a month's worth of rain in a couple of hours in some places. 'You will see quite a lot of water on the roads and difficult driving conditions. 'Hopefully nothing more significant than that, it certainly won't be an issue for any of the rivers because they are quite low.' Low pressure and humid, moist air across the country will cause the heavy, thundery showers, but even within the warning areas some places will stay dry, the Met Office said. 'There is a good chance of seeing some lightning and some hail, with some gusty winds as well,' Mr Partridge said. The rest of the week is set to be changeable, with showers likely tomorrow and thundery downpours possible in the South East of England on Wednesday. Temperatures this week will be around average for the time of year. The wet weather comes after a dry and hot spring and three heatwaves so far this summer which left four regions of England in drought. England recorded its driest March to June period since 1893, according to the Environment Agency, and dry ground can make flooding more likely as it is unable absorb as much water. Today, Southern Water became the latest company to activate a hosepipe ban, to protect rare chalk stream habitat in response to the driest start to the year since 1976 for England. The company said restrictions were being imposed on hosepipes for activities such as watering gardens, filling paddling pools or washing cars. The move aims to protect the Test and Itchen chalk streams, which supply most of the area's water, but are at 'critically low levels', down 24% on normal flows for the time of year, Southern Water said. Rainfall across England was 20 per cent less than the long-term average for June, which was also the hottest on record for the country, with two heatwaves driving unusually high demand for water, the Environment Agency has said. Drought was declared in East and West Midlands last Tuesday, with the region joining swathes of northern England in drought status. Southern Water's water managing director Tim McMahon said: 'We're sorry we're taking this step, but as other water companies have already done, we have to respond to the widespread and prolonged dry weather affecting our region. 'In our case, this means a hosepipe ban for our customers in Hampshire and the Isle of Wight to protect the health of our amazing chalk streams, which as one of the rarest habitats on earth has been compared to the Amazon Rainforest. 'We must act now to support the wildlife that live there, including Atlantic salmon and southern damselfly.' He said the company has been working '24/7' to find and fix leaks, and ensuring the network is working as efficiently as possible, but it is 'not enough', and he urged customers to help to reduce use by adhering to the ban.
