What is the barometric pressure in Allentown today?
The live reading at the top of this page is the latest sea-level pressure reported by Allentown/Lehigh Valley Intl (KABE), 7 km (4 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Allentown?

Why does a barometer in Allentown read lower than the forecast?
Allentown is close to sea level (about 338 ft), so absolute and sea-level pressure differ by only about 0.36 inHg (12 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
