Pressure and weather in Haverhill
Haverhill straddles the Merrimack River about fifteen miles inland from the Gulf of Maine and thirty miles north of Boston, a position that puts it in one of New England's more meteorologically contested spots. The valley funnels air along its axis, and the city is close enough to the coast to feel the ocean's moderating warmth yet far enough inland that a northeast wind off the cold Gulf of Maine can hold temperatures down all day. Winter is governed by the nor'easter. These lows deepen off the Mid-Atlantic coast, and their central pressure can fall thirty hectopascals in twenty-four hours in a bombing event, dragging current barometric pressure in the Merrimack Valley down with them. Because Haverhill sits near where the coastal front typically stalls, the same storm that buries the towns just inland can deliver a cold, wind-driven rain here, or the reverse. Behind the low, arctic high pressure floods in and the barometer climbs steeply. The other seasonal risk arrives from the tropics: a recurving hurricane or its extratropical remains, most likely in late August and September. Summer is comparatively placid under the Bermuda high, with thunderstorm outflows providing brief pressure jumps. A barometric pressure forecast for Haverhill matters most from December through March.

Can barometric pressure cause headaches? Northeastern Massachusetts is a place where the barometer moves a great deal, and the classic report from weather-sensitive residents is that the twelve hours before a nor'easter arrives are worse than the storm itself.
