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...
