I don't know where Katerina Christodoulou was producing her bulletins, but the NE&C bulletin was in native HD rather than upscaled usually from the Leeds weather studio.

I know she also covers shifts for the London weather hub, however Sara Thornton was on BBC London/Look East/South East Today.

The giveaway can often be the clicker used. The regular London hub often have no clicker for Breakfast and weekend hub forecasts suggesting they continue to work from home. When others cover like Katerina they often have the London long thin clicker that I haven't seen elsewhere. Most regions have what looks a bit like a car key.
