A third update to the ongoing saga of the thunderstorms that are forecast for coming week. It seems that the UKMO have now narrowed the area down a bit, but are still uncertain about the location and timing of any thundery activity. So wouldn’t it be a good idea not to have issued an update today at all? Perhaps waiting till tomorrow morning before issuing one when hopefully the NWP model and supercomputer can give a more accurate and specific guidance? That would still give the public ample time for people to take avoiding action. Forecasting thunderstorms, even with the most sophisticated highest resolution models, is still fraught with difficulty and something that probably will never be achieved with any great degree of accuracy.
