Can anyone explain to me how whilst it's -2.5C and vis is not that
good here in North Yorks with a light breeze, there's no frost and no
standing water is frozen - that includes our little garden pond or any
of the puddles on the road side or in the fields...

I dunno, everything frozen solid here. Some frost but not a great deal.
And it's even snowing!
