Wales is also expected to sizzle on Saturday as temperatures in Cardiff and Wrexham are forecast to hit 21C.

"So get your sun hats and sun block ready but be aware that the pollen count will be high."

This could affect football fans heading to or from Sunday afternoon's Premier League game between Cardiff City and leaders Liverpool at Cardiff City Stadium.
The RAC has also warned stretches of motorway just outside of Wales will be among the UK's busiest this Easter - the M5 south at Bristol and the M6 in Cheshire.
"We are predicting Good Friday will be the worst for traffic from late morning into the afternoon," said Dan Croft, of traffic data analysts INRIX.
"For drivers looking to avoid the worst congestion, the best options are to travel on Saturday and set off early in the morning."
