Ireland in freak 'pressure cooker' heatwave amid urgent 30C weather warning
The so-called Azores High weather phenomenon is set to trap a bubble of rapidly warming air like a pressure cooker. While much of the country is already experiencing humid conditions and temperatures around 25C, the real heat is expected to intensify from Thursday, peaking during the weekend.
Met Eireann forecaster Deirdre Lowe explained the phenomenon in a social media update this afternoon, saying: "While there will be a good deal of cloud at times over the next couple of days, as we head towards the weekend, longer spells of sunshine will develop with some very warm or hot weather on the way.
"That's as the Azores High builds up over Ireland on Thursday, and then as it moves away to the east, it will allow continental air to be advected up over Ireland in a southeasterly airflow for Friday and the weekend."
She also confirmed that official weather warnings are likely, with urgent status yellow heat alerts expected in the coming days.
Deirdre added: "We will likely be issuing yellow high temperatures warnings in the next couple of days, and we issue these when daytime temperature exceed 27C and nighttime values stay above 15C.
"Thursday will be a dry day for most with warm spells of sunshine, although possibly saying cloudier across northern and northwestern areas with a chance of a few showers and top temperatures on Thursday of 21C to 25C.
"For Friday then, after a foggy start for southern areas, widespread sunshine will likely develop, becoming hot in the sunshine and highest temperatures of 22C to 27C or 28C, all in a light southerly breezes.
"And looking ahead to the weekend, it'll be sunny with very warm or hot days, widespread sunshine and temperatures widely in the mid to high 20s, possibly touching 30C in a few spots, but there is a chance of some showers later on in the weekend."
Whether or not this warm spell becomes an official heatwave remains to be seen. Heatwaves are often defined as five consecutive days of above-average temperatures, however Ireland's weather service uses a stricter definition.
It previously told the Irish Mirror: "That is a working definition used by some other met offices, but the Met Eireann definition of a heatwave is five consecutive days of temperatures above 25C."
With current forecasts predicting multiple days of scorching temperatures, it appears Ireland is on the brink its first official heatwave of the summer thanks to this rare 'pressure cooker' setup.

9 cheap & free hacks to stay cool while sleeping in hot weather – from avoiding fans to shutting windows & warm showers
IRELAND has been urged to shut the curtains, make sure windows and doors stay closed during the day and be wary of fans as temperatures soar to a boiling 32C this weekend. And as the country prepares to toss and turn as they try to settle down for the night, a sleep expert has revealed her top tips for staying cool in the sheets. 3 Met Eireann has issued a spate of weather warnings this weekend Credit: Met Eireann 3 Sleep expert Lucy shared her good night's sleep tips with the Irish Sun Credit: Paediatric Sleep Consultant Lucy Wolfe said the key goal is to cool down the room early and lower your body temperature. She told The Irish Sun: 'Certainly at the moment, I would explore things, anything that would cool you down because it is the cooling of the body down is the key thing. 'So even just having a warm shower or bath before bedtime, even though that feels counterintuitive, that can help drop the body temperature down, alongside creating your cool When it comes to bedding, Lucy recommends 100 per cent breathable fabrics like cotton or bamboo - and she warned that a duvet is just "too big" at the moment. READ MORE ON HOT WEATHER She explained: "So, maybe just a sheet and be very conscious of what you're wearing, what you're eating and also trying not to stress. 'Because when you are not getting sleep or you're not staying asleep, we create a cycle of tension. 'So it's just staying grounded in it. Maybe some mindless activities, some reading, listening to 'The stress pumps up the adrenaline in the body as well.' MOST READ ON THE IRISH SUN WINDOWS SHUT If taking a nap during the day, Lucy advises to keep those windows shut - as having them open could make the house even hotter. Stay Cool Hot Weather Bedroom Tips She explained: "It's only worth opening windows if it is cooler outside than it is inside. 'Sometimes it's not worth having the windows open when it's really hot outside. 'But as the day cools down, it's worth then having some windows open." But Lucy stressed that having the windows open could create more difficulty for those who live in noisy areas. She added: "So you've got to factor those things in, especially if you're thinking about leaving windows open overnight." The Paediatric Sleep Consultant explained the key is to cool down the bedroom during the day. She said: "It's definitely worth having blinds pulled down early in the day.' BODY TEMPS With temperatures high in the 30s, it can be very tempting to purchase a quick fix like a fan - but the buy may not be worth your money. Lucy advised: "In terms of the fans, they are a good idea. But sometimes they can just be a bit ineffective because they're just moving hot air around the room. 'So generally, I recommend that if you're using a fan, moving cold air around the room as opposed to warm air.' The expert admitted wearing pyjamas or going commando is a very 'personal choice'. The HSE recommends only using a fan if the temperature is below 35C in the room. CLOTHING CHOICE Lucy recommended wearing loose clothing that will let your skin breathe whilst trying to take a sleep. Swapping to breathable fabrics can be a game-changer in the heat. She said: "If you generally wear "Ideally made from natural materials like cotton or bamboo. 'I think it's about trying to cool everything down, to help you get asleep and to stay asleep.' FOOD OPTIONS Lucy encourages people to think about 'sleep-friendly She said: 'Heat and sleep don't go well together. Then obviously digestion creates heat. 'This is why the environment at the moment is unhelpful to get to sleep and stay asleep. 'So I think light meals are what would be recommended generally and avoiding heavy meals, two or three hours before bedtime. 'But there are sleep-friendly foods that you can incorporate, for example banana, wholewheat, some seeds, lettuce, turkey. 'They all have good sleep promoting properties, and that is where we usually go to when we are looking at a small supper style food.' NATURAL SCENTS When it comes to pillow sprays and oils, natural is the way to go. Lucy said: 'From a sleep hygiene perspective, I do encourage any supports that help your sleep. 'Some natural pillow sprays and natural oils diffused in the room can really be helpful to initiate a sense of calm and grounding. 'Because these are the ingredients that are helpful to get to sleep, so you're trying to create that constellation of things, especially at the moment where environmentally it's more challenging." COOLING GADGETS While Lucy 'is not mad about' cooling items like cooling pillows and mattresses, they can be worth exploring if they work for you. She said: 'Freezing your hot water bottle, freezing your socks, things like that to try and help lower the temperature. 'If your room is really warm, cooling pillows, anything really that would help cool things down.' The sleep pro stressed it's important to find what works for you. PERSONAL CHOICES She continued: 'There's some evidence to support white noise helping you to go into a deeper sleep quicker and fall asleep faster as a result of that and go into a deeper sleep. 'But I do think those things are personal preferences. "Some people will be driven insane by the white noise and other people find it comforting and soothing. "It can also can act as a barrier to mask outside noises. 'So again, I'm really open to exploration. These things can offer really good sleep supports, but not for everybody. "It's about trying to find out what's your individual sleep profile. 'Earplugs, eye masks, all these things can be great, but they are individualised.' UNWINDING For yogis who like a good stretch before bed, there's good news. Lucy said: 'I don't think we need to cut anything out. We would normally recommend that, avoiding strenuous activity two to three hours before bedtime, but gentle stretching, exercises, and yoga, they can be helpful to help relax the body. 'But at the moment, if you're finding that is heightening your body temperature, it might be worth doing it earlier in the evening time. 'So just remember that in order to get to sleep with ease, the body temperature needs to drop. 'Now that is a hormonal constellation biological process that you are trying to initiate by having regularity already embedded in your sleep profile. 'Regular wake times, a regular bedtime, some level of a pre-sleep ritual, and then maybe a few exercises or practices you have in play. That will help your body wind down.' BLACKOUT With the sky still bright at 10pm, the sleep pro said there are alternatives to black out blinds. She said: 'The brightness has such a big impact. It stimulates the waking part of the brain, which you're obviously trying not to do. 'So I guess in the absence of blackout blinds or curtains, I think an eye mask is a great way to help make it all dark.' Those who do have black out blinds will benefit from the shade, which will reduce your bedroom from summer sunlight. The handy blinds will also increase the privacy of your home at night. 3 There are multiple healthy habits you can have in order to get a better night's sleep Credit: Getty
