Hello Hugh,
Ken's explanation is probably the main reason why temperatures don't
rise immediatedly at sunrise,
but there is another factor, transport of cold air, that can delay the
rise in temperature and even produce the legendary 'post dawn
freeze'.
This is highly dependent on locality.
After sunrise when the solar flux is sufficient to warm the surface,
the surface temperature inversion begins to erode.
This allows movement of any surface air which might have been trapped
in cold air pools or frost hollows.
It is likely to drain to lower land, producing a temporary dip in air
temperature.

Great! Thanks, Len.
