The Met Office and BBC have forecasted the exact date when the UK will be hit with a final warm spell of hot weather before the temperatures plummet.
According to weather experts, Britain will witness warmer weather in October after going through a spell of thunderstorms and floods during September.
The Met Office says “high pressure” will hit the UK in the form of a “ridge” – sparking warmer weather in October.
Temperature levels could reach 20C at times during October, as the run-in to Christmas continues.
The Met Office’s long-range forecast (Saturday 30 September – Saturday 14 October) states: “Overall, temperatures are more likely to be above average than below, with an increased chance compared with normal of some warm spells, but also some cooler nights.”
Looking from September 30 to October 14, the Met Office goes on to add: “Overall, temperatures are more likely to be above average than below, with an increased chance compared with normal of some warm spells, but also some cooler nights.”
Jonathan Vautrey, meteorologist with Met Office, said: “With southerly winds coming up from Europe, that’ll generally bring a slightly warmer direction of air for us and would then allow those temperatures to climb a touch more.”
He added: “We may not see necessarily the same extreme heat building as this month but it will allow the temperatures to rise above average from the time of year.”
The Met Office is predicting thunderstorms to arrive on Monday with a danger to life as several yellow warnings are in place for parts of England.
Met Office meteorologist Ellie Glaisyer said: “It will be a mild and humid night in the South which could make for uncomfortable sleeping.
“But in rural Scotland, there will be less cloud cover – we could see frosts with temperatures dropping to minus 1°C overnight.”
Ms Glaisyer went on, saying: “Unsettled weather on Monday and into next week will see temperatures return to the average for the time of year, and it will “start to feel fresher, and much more autumnal”.
Speaking of the week from Monday, October 2, to Tuesday, October 10, Ian Simpson, forecaster for independent team Netweather, said: “It looks probable that we will see one or two relatively settled interludes early on in the period with ridges of high pressure moving in, most likely from the south.
“Temperatures are likely to be above normal early in the period, but trending average to fairly cool late in the period. It will probably be drier than average for most, particularly in the west and north-west.”
