Strong winds have already wreaked havoc in many regions this week, with gusts peaking at 76mph at Capel Curig in Wales yesterday. But more bitter conditions are on the way as low pressure is forecast to sweep a new cold chill over the UK from a northerly direction. Temperatures could plunge to -3C in north-western regions on Thursday, including Carlisle and the Lake District, according to WXCHARTS.
Further down in Yorkshire, lows of 0C could also strike Leeds and York on the same day, while London and Kent in the south-east are slightly warmer at 1C.
The latest temperature anomaly maps from WXCHARTS show the whole of the UK turning different shades of blue on Thursday, May 6, as the cold air hits.
Blue indicates temperatures far colder than usually expected at this time of year.
