May I ask where you found the Marham minimum of -11.5C.
I looked on the MO website and the minimum was quoted there as -12.9C.
It is the 12-hour overnight minimum as reported in the 06.00 synop

I think the figure on the MO website is the 24-hour minimum read at 09.00. On the above link, you can see that -12.9°C was reached after 06.00.
