Oxfordshire can expect plenty more heavy rain showers throughout the afternoon, according to the Met Office.
The weather experts have issued a yellow warning until midnight for thundery and heavy showers to fall across the county.
The Met Office said a "slack area" of low pressure will move slowly across southern Britain today, bringing unstable air and the potential for thundery showers.
People are advised to plan their journeys to avoid delays.
Fans travelling to tonight's big clash between Oxford United and Swindon Town FC should pack their rain coats.
