This cold blast comes after the Met Office warned Britons could be hit by colder temperatures later this month as a weakening polar vortex threatens to bring Arctic air.
uncertain
vortex → rise → air
The polar vortex is a ring of powerful winds that helps keep freezing air near the North Pole.
asserted
that → help → Pole
If it weakens, it could allow colder Arctic air to sweep south towards Britain, increasing the risk of wintry weather.
But Met Office forecaster Honor Criswick said: 'We can't link what's happening to the polar vortex now to what is currently happening in the weather.
'Because the polar vortex takes place so high up in the stratosphere, it would take a few weeks for any of those impacts to then possibly be seen in the UK, because it's not guaranteed.'
She added: 'In time we could have a look and see if what's happening now with the polar vortex and in a few weeks see what happens to see if that has an impact on our UK weather.
uncertain
that → weaken → weather
However, it does look like it's a slight blip before things generally turn to more average for this point of the year - so a chance
