errrmmm... your barometer also isn't located where their barometer is
located... it is entirely possible for them to be experiencing a rise in
pressure while you experience a drop in pressure... stop twiddling... find out
what the pressure actually in your locale within 20 miles (for instance), set it
to that and let it go...

an example of similar nature... we watch a TV station that is located some 60
miles away... our cold temperature is generally 5 degrees lower than what they
project and/or report their's to be... i don't remember about our hot
temperature but i think it is about the same offset higher... the reason this is
is because their readings are taken at the airport (RDU Int'l) or their station
facilities building (in the city) whereas we are located in a slight valley in
rural, hilly country with a lot of trees and streams around us...

perhaps you are/were trying to be too precise? the only way your barometer will
ever follow their's is if its located in the same place as theirs...
