The GFS weather<\/a> model shows temperatures will start rising on May 4, hitting 21C and 22C<\/a> across large swathes of southern and central England. North Wales could also see highs of 21C at around 6pm.<\/p>\n

The mercury is expected to keep rising throughout the week, hitting 24C in the south-east on May 5 as London gets the best of the heat. A few places in Scotland could hit 20C at 6pm, with highs of 23C possible in Wales.<\/p>\n

Despite the sweltering temperatures, this warm spell at the start of May is not expected to constitute an official heatwave<\/a>. An official heatwave is declared when temperatures reach or exceed the heatwave threshold for three consecutive days.<\/p>\n

The heatwave threshold varies from 25C to 28C across the UK. It stands at 28C in the south-east of England where temperatures tend to be warmer, and drops to 25C the further north you go.<\/p>\n","protected":false},"excerpt":{"rendered":"Brits could soon face scorching temperatures as high as 26C as weather forecasting maps reveal the mercury is…\n","protected":false},"author":2,"featured_media":19200,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[173,4832,27,257,3930,1143,5,6,38,150],"class_list":{"0":"post-19199","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-uk","8":"tag-england","9":"tag-heatwave","10":"tag-london","11":"tag-met-office","12":"tag-northern-ireland","13":"tag-scotland","14":"tag-uk","15":"tag-united-kingdom","16":"tag-wales","17":"tag-weather"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@UnitedKingdom\/116446833062926451","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/posts\/19199","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/comments?post=19199"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/posts\/19199\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/media\/19200"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/media?parent=19199"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/categories?post=19199"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/britain\/wp-json\/wp\/v2\/tags?post=19199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
