Boston and “bomb cyclones”
Boston is often in the path of coastal storms that deepen quickly. Meteorologists call it bombogenesis when a storm’s central pressure falls very fast: by 24 hPa (about 0.71 inHg) in 24 hours at 60° latitude, and a little less at Boston’s latitude. Some nor’easters deepen this way off New England. In the city that shows up as a steep fall on the chart and a sharp rise afterwards.
Sea level or barometer: 29.96 inHg and 29.92 inHg in Boston
The model point for Boston is at about 30 ft, so here the two numbers are close. Pressure drops by about 0.1 inHg every 90 feet of height.
In the Weather24 app you choose which one to see under “Pressure reference”: Local, the default, shows a value close to a barometer’s; Sea level shows the forecast value used on this page.
Pressure swings in Boston and how you feel
Weather-sensitive people usually notice changes in pressure — especially a fast fall ahead of a front — more than the value itself. That is why it helps to watch the change over the last 3 hours and the last 24.
