In the last couple of hours, the high ground of east Dartmoor (possibly around Haytor) seems to have triggered a thundery shower that quickly tracked NNE across the west of the city of Exeter. It looks to have been quite an intense, but short sharp shower. I say thundery, but so far Blitzortung has only detected one flash of lightning from it.
What seems very silly to me, watching the latest forecast on the BBC News channel (which looks like it may have been taped), is how the weather presenters prefer to use NWP model rainfall rather than real-time weather radar images. In a dynamic convective situation like today, you would have thought that’s what they would be most helpful to the public. Likewise the BBC presenters never ever use real-time SFERIC data, or come to that rapid scan 5 minute visible satellite imagery. What’s the point of having all these various ways of observing the weather in real-time, and then not using them?
Certainly use NWP images for forecasting, but masquerading NWP forecast data as real-time observational information is wrong and just plain misleading.
I remember coming home from work on the 16th of August 2004, it must have been just before 4 PM, to watch Michael Fish prattle on in the forecast about how hot it had been recently in Greece. This too was a taped forecast that they used on the same BBC News channel. The news was later interrupted by breaking news about flash flooding that was occurring at that precise moment in Boscastle. It seems to me that little has changed since then in how we present the weather, if this intense shower that I noticed this afternoon had been slow-moving and a little larger, the same thing could have easily happened all over again.
