A WEATHER warning for heavy rain and thunderstorms has been issued by the Met Office for the weekend. 

Oxford was set to reach highs of 30C this week, hotter than the sunny party island of Ibiza. 

Health bosses and GPs even urged vulnerable people to take shelter inside from the heat and revealed a list of seven tips to do this weekend. 

But now the forecast has completely changed and plans for a legal gathering of six people outside might have to be swapped for a video call instead.

Today Oxford is still set to bake in 31C heat. 

The hottest time of the day will be from about 2pm to 6pm, before temperatures drop to a cooler 22C tonight.
