just before dawn I notice just traces of frost but nothing much
An hour later after it is light- I notice the frost is much more
intense - white over - and ice on the roads.
I would be most grateful for an explanation of why this happens and
what it is called.

. I would guess that if the temperature is dropping at a certain rate
and the temperature is near zero there is a lag before the sun has any
strength, especially at this time of year, and it continues to fall for a
while.

You mean it is a miracle that these thing endeavour to occur on time
no matter how early it gets early?

It isn't that -for sunlight would have degree of hesitancy, day to
day. And it would be so unlikely to occur as sequentially as described
as to be impossible.

2 in 365 is rather a remote chance but every day there is this
phenomenon it occurs just after dawn?

It has to practical and logical as well as obeying the physics of the
school syllabus.
