I'm going to keep an eye on the models and try and highlight where the greatest risk of thunderstorms might be and when this week.
At the moment, the highest risk appears to be tuesday evening, after a hot to very hot day for many (perhaps just warm for some northern coastal areas). Temperatures around London could be around 33/34C and 30C quite widely in the Midlands.
That evening (tomorrow evening!) it looks as though this plume of hot air could then destabilise. At the moment GFS has the highest risk of severe storms around the Liverpool/Manchester/Birmingham and north Wales region. However, there is a good risk of moderate storms showing later on in the night through the Exeter region and upwards. The SE appears to escape the main risk area.
As always with storm forecasting there are no promises. Its a bit like a forest fire really, sometimes all of the conditions can be perfect, yet a spark dies out quickly, other times a blaze can take hold. Also, one town may see a huge storm, while the next one sees nothing.
I will update as we go through today and tomorrow.
