Like I said, it really is pointless trying to match your temp readings to another station unless it is literally sitting on top of yours.
Barometer and Relative Humidity are more something you want to try to get in line with another station IF you know that station is reporting accurate information. Just because a station is a NWS reporting station does not automatically mean that what it is reporting is gospel.
For example... The NWS station down in Oakhurst Ca. (Davis VP2) is owned and operated by the NWS in Hanford Ca., but it is in a KNOWN micro-climate area. Its overnight temps are a good 8-12 degrees colder than the majority of the Oakhurst area, but because the siting location needed to be a government owned property, the local Sheriff station was tapped to run it. They didn't have any other location options. This station is repeatedly getting RED Xs and Thumbs down by the MADIS QC system.
The lows are off enough that I contacted the NWS Hanford office and found out that they were aware of the problems, but as I said, they had no other siting options at the present time.
If they have a choice between several PWS stations in an area, they WILL go with the most accurate and reliable one. (uptime) My station is the official NWS reporting station for Bass Lake Ca., and I was chosen because my data IS the most accurate in the area they needed to cover and I had a significantly better uptime perentage than any other private station around here. (Thank you LWC!)
So... I do know a lot about this particular subject.
