Pressure and weather in Glen Burnie
Glen Burnie sits on the low coastal plain a few miles inland from the Patapsco and the upper Chesapeake, close enough to tidal water that the bay writes itself into the daily weather. In summer a bay breeze pushes inland through the afternoon, often stalling thunderstorms that drift east off the Piedmont and holding temperatures a few degrees below the suburbs further west. The most unsettled season is winter, when the town sits almost exactly on the average rain-snow line: coastal lows running up from the Carolinas can drop heavy wet snow one week and cold rain the next, and the difference is often a single degree. Those coastal storms produce the year's sharpest pressure falls, typically January into early March. Late summer and early autumn bring the tail ends of tropical systems up the bay, which arrive as long, slow declines over a day or more rather than the abrupt drops of a winter nor'easter.
What this means for you
Nor'easters here can deepen quickly just offshore, turning a modest fall into a steep one within hours. If you get a weather migraine, an overnight barometric pressure forecast is more useful than a morning glance at the sky.
