Volatile weather is to blame for wild differences in BBC and ITV bulletins
Rival sets of television forecasters compete to correctly predict our weather for the following few days. This happened because three years ago, at the behest of the government, the BBC gave the contract to the lowest bidder, dumping the Met Office after 94 years. From 6 February 2018, the MeteoGroup, took over.
ITV still gets the Met Office forecast, so if viewers care to switch channels at the end of the 10 o’clock news they can get a second version of what the weather will be next day.
