Well, I can see why everybody's talking about Joanna Donnelly She is so much more natural than Siobhan Ryan or Jean Byrne in her delivery. She is definitely bringing something new to the weather forecast! Let the battle of the weather forecasters begin? I think the faithful Irish public will still be fond of Jean and Siobhan, though. They'll just add Joanna to the list of best-dressed Irish weather forecasters. But who will present the forecast on Christmas Day? That's the real question!
