When the weather systems reaching the UK are coming from the northerly Icelandic direction instead of from the sub-tropical Azores, no prizes for guessing what happens next. While the UK searches for any signs of summer, Eastern Europe has a heatwave. Sky decides to explain about the jet stream anyway, in case you overdosed on the media’s human-caused warming propaganda and thought you were entitled to expect warmer weather than what’s arriving now.

June’s wet and grey weather does not feel particularly summery, so what is going on and, more importantly, when will it warm up?
Last month was the UK’s hottest May on record, as higher temperatures during the night and warm weather in Scotland pushed up the temperature to about one degree above average, says Sky News.
But just over a week into June, the mercury has dropped.
“It seems like we’re one to three degrees below normal for this time of year,” David Schultz, a professor of Synoptic Meteorology at The University of Manchester, told Sky News.
The temperatures across the UK on Sunday were between 10C and 17C from midday, according to the Met Office.
The average temperatures for this time of year are usually between 13C-16C in the north and 17C-19C further south, so this weekend was “average or just below”, but the showers and breeze made it feel colder, according to Met Office meteorologist Marco Petagna.
The drop in temperature is down to a change in the jet stream, a core of strong winds about four to seven miles above the Earth’s surface.
These winds impact the weather closer to the surface. Currently, the jet stream is further south than usual and coming from the northwest.
Jet-stream switch
“Normally in the UK, we get the jet stream from the southwest,” Prof Schultz said.

Prof Schultz added because climate change has pushed up average temperatures, we notice more when our weather gets colder.
“We might be complaining about a few degrees cooler than normal but historically, this spell might actually be closer to normal,” he said.
