UK temperatures to rise above 20C - but only one city in England will feel it

New UK weather maps show the exact date temperatures will rise above 20C after a drab and miserable start to June. The WX Charts and NetWeather TV projections, using InMeteo and Met Desk data, have shown when the mercury and thermometers will spike north of the 20C mark again.

Netweather say that temperatures of 21C will be reached on Friday, June 28 - but only around the London area. Jim Dale, who is senior meteorological consultant and founder of British Weather Services, said: “For now we’re locked into something of a damp chilly rut, the opposite of record 40-45C heat and unbroken sunshine in Eastern Europe.

“We are at the mercy of an active jet steam and occasional modified Arctic air, more akin to Autumn really. Patience is still required as we’re only 14 days into summer. A little more warmth through next week should help.”

The Met Office says of June 18 to June 27: "It is most probable that initially fine conditions will prevail for most, with more changeable conditions with cloud and some rain being confined to the far north and northwest, temperatures will likely be close to or slightly above average.

"Although even during this time, a few daytime showers could pop up in the east. However, there is a slight chance of an alternative scenario that initially an area of cloud could edge northwestwards from Europe and bring a few days of thundery rain and fairly hot / humid conditions to the southeast. Into the last week of June, on balance it appears more probable that milder than average conditions will continue, with the wind from the southerly quadrant."

The forecasting agency goes on, detailing in its latest medium-term outlook and forecast this week: "During this time rainfall looks quite variable (some places dry others wet)."
