Default Cape and Li instability data for coming Tuesday and Wednesday

I've only recently started looking at this GFS output data.
Is max/min of -8 and 2000 sort of figues exceptional or perfectly
normal for thundery type conditions over the UK?

Yes, 2000 usually required,also depends on shear.
Tues and Wed evenings this week most likely but the trick is exactly where in the UK?

UKMO just give a large yellow warning blob for rain.

AFAICS the scales they choose for these graphical data plots is fixed
for all time and when I see colours right at the exreme, I naturally
seem to think it must be extreme, as something like Poisson distribution
assumed
