Pressure and weather in Monroe Township
Monroe Township lies in southern Middlesex County on the gently sloping inner coastal plain, roughly midway between New York and Philadelphia and about twenty miles inland from Raritan Bay. Its winters are notoriously hard to forecast for one reason: the boundary between cold air and marine-modified air very often lies across this part of central New Jersey during coastal storms. A low tracking just offshore keeps the region entirely in snow, while one edging slightly inland pulls Atlantic air over the coastal plain and turns the same storm to sleet and rain within a couple of hours. Either way the barometric pressure signature is a slow, deep fall over a day or more as the low deepens off the Delmarva and then a firm rise as it pulls away northeast, and the falls in current barometric pressure during a major nor'easter are among the largest the region records. Away from winter, the local rhythm is different. Late spring and summer bring a sea breeze that pushes inland from the bay on most sunny afternoons, arriving as a subtle wind shift and a temperature drop with essentially no barometric signal, though it can trigger thunderstorms where it collides with warmer inland air. The tropical season occasionally sends a decaying hurricane up the coast with heavy rain and a smooth pressure minimum. A barometric pressure forecast for Monroe Township is most useful from December into March.
What this means for you
Can barometric pressure cause headaches? Central New Jersey gets both slow multi-day declines from coastal storms and abrupt little sea-breeze shifts that never touch the barometer, which is a useful contrast when working out what affects you.
