Spanish plume could bring 25C highs in coming weeks - here is the latest Portsmouth forecast
A heatwave could be set to bring 20 degree weather in the coming weeks, according to reports.
The warm conditions could be caused by a ‘Spanish plume’, with high pressure coming in from the continent at the end of April and the start of May.
Highs of 25C could be seen in the south of England, according to the Weather Outlook.
Britain may also be set for the hottest summer in a decade, the Sun reports, with La Nina playing a role in any potential temperature spikes.
The Met Office says that a Spanish plume is caused when ‘very warm air pushing north from the Spanish plateau on a southerly airflow’.
It can happen ‘at almost any time of year’ but ‘during the summer months the extra warmth and moisture lead to increased energy available for storm development’.
On its long range forecast for the UK, the Met Office is predicting that temperatures will be warmer on Friday and it will be settle and dry over the weekend.
Next week it will be ‘settled’ and there will be ‘warmer days are most likely to be further inland towards the south’.
Further into May, the Met Office is forecasting that ‘the UK will likely see spells of fine, dry weather at times with fair-weather cloud and plenty of sunny spells, as well as an increased likelihood of more unsettled periods when compared to April’.
There is potential for ‘the possibility of some warmer spells’ between May 5 and May 19.
