The latest breakthroughs, research and news from the Met Office. When positive lighting strikes it is forced to go around the negatively charged base of the cloud, this generally results in a more powerful lighting strike which shoots out sideways and sometimes can travel a mile more away from the storm cloud before connecting with the ground. As well as being attracted to the positive charge in the top of the cloud, the surplus of electrons in the cloud base are attracted to positive charge in other clouds and on the ground. Some of the hail that forms becomes too heavy to be propelled by the updraughts and so begin to fall back through the cloud, bumping into smaller ice particles as they do so. You can also search for world forecast locations. With a Met Office yellow thunderstorm warning in place, it can be important to see where lightning is striking near you. As negative charge builds at the base of the cloud, the electrons near the ground's surface are repelled.
