This blog uses the location of Wings Field, Blue Bell PA when referencing timing of precipitation moving in, not Philadelphia airport.

Blue Bell (KLOM) is more central to my forecast area than Philadelphia airport (KPHL) . Other reasons: It is also not near sea level and not close to a major body of water (Delaware River).

Temperature forecasts also use Blue Bell, which often is 1-3 degrees cooler than Philadelphia Airport.
