Basically they always end the Ten during these events with stay tuned, but the reality is you won't get a further update until breakfast.

There's a forecast after Newsnight on BBC Two and an extended forecast on BBC One just before the handover to the News channel. You can also access the BBC Weather website and app through the night. Most TV viewers are also in bed between the end of the Ten and start of Breakfast. There just isn't the demand for more television weather forecasts through the night - the reach for the weather forecast at the end of the News at Ten is roughly 100x greater than that of the 23:57 forecast on the News channel.
