The barometric pressure at a particular elevation
is determined by the standard barometric pressure
at sea level, the particular elevation (if you are
above sea level) and the average mass of air at
that elevation, as well as the temperature. So the
barometric pressure does depend on temperature.
Since the temperature changes with the time of
day, that in turn means that the barometric
pressure also changes with the time of day.
