UK weather maps reveal 3C cold snap with 108 counties plunging below 10C The GFS weather forecasting model suggests daytime temperatures could plunge below 10C in every county across the UK as Brits face a cold snap later this month Weather forecasting data suggests the UK faces a cold snap later this month, with daytime temperature dropping below 10C in all 108 counties across the country. The GFS weather model shows minimum possible temperatures dropping as low as 3C at midday on September 23 in Scotland, with 5C in Northern Ireland, Wales and the northern England, and just 11C in the south-east where temperatures tend to be warmer. Data for later in the afternoon shows highs of just 14C in the south-east, 12C in the Midlands and Wales, 11C in Northern Ireland and 10C in Scotland. Similar conditions are expected on September 24. The GFS model shows minimum possible temperatures below 10C in every county at midday, with 5-9C on the cards across much of the UK. By 6pm, the data suggests late afternoon highs might reach just 15C in the south-east, 13C in the Midlands and Northern Ireland, 12C in South Wales and 11C in Scotland. This all comes as the strongest El Nino on record is expected over the coming months. Met Office meteorologist Aidan McGivern has described this year’s El Nino as a “beast” and said the UK is facing “uncharted territory” - as not only is it expected to be the strongest El Nino on record, but it will also be bolstered by global warming. El Nino will peak towards the end of this year and have varying impacts in different places - bringing increased rainfall to some areas and drier spells to others. Mr McGivern said: "Very wet conditions [are expected] through the Pacific as well as southern California. Other southern states in the US, into Mexico, coastal parts of South America [all face] above average rainfall and more storms." For the UK, “well above average rainfall, especially to the south-west of the UK” is on the cards. Mr McGivern clarified that El Nino is not the only thing that can impact our weather, so these outcomes are not guaranteed. “And we’ve got global warming to think about, the fact that sea surface temperatures are significantly warmer than average in many places,” he said. “That combined with El Nino could fuel more rain when storms happen. So if we get more storminess in the UK… those storms will contain more moisture as they’re passing over warmer seas.” El Nino occurs every few years when temperatures in the tropical eastern Pacific rise 0.5C above the long-term average. It generally causes an increase in global temperatures in the summer, while autumn and winter tend to be wetter and stormier.
