THUNDERSTORMS are to hit Bradford from tomorrow, forecasters have warned.

The Met Office has issued a yellow weather warning for much of northern England, in place from 4am on Friday until midnight on Sunday.

"Heavy showers are expected across much of the UK on Friday," says the warning.

"Within the warning area these showers and thunderstorms will be slow-moving and may cause localised surface water impacts.

"Rainfall totals will vary considerably and not all locations will be affected by the heaviest showers.

"However, where the showers do occur there is potential for 20-30 mm of rain in a short space of time and during the course of the day there is a chance that some places could see as much as 80-100 mm build up."

The warning for Saturday adds: "Heavy showers are expected to break out across much of the UK again on Saturday.

"The heaviest showers are expected within the warning area where some of the showers will be slow-moving and thundery.

"Not all locations will be affected by the heaviest showers, with some areas escaping much in the way of rainfall.

"However, where the showers do occur there is potential for a further 20-30 mm of rain in a relatively short time period and during the course of the day there is a chance that some places could see as much as 50-70 mm building up."
