Pressure and weather in Silver Spring
Silver Spring sits immediately north of the District of Columbia line on the rolling Piedmont, a short distance above the Atlantic fall line where the hard rock of the uplands gives way to the coastal plain. That in-between location — inland of the Chesapeake, east of the Appalachians — makes for a busy barometric pressure record. In the cold season, coastal storms and nor'easters developing along the mid-Atlantic seaboard produce the deepest falls in current barometric pressure the area sees, and because Silver Spring sits close to the usual rain-snow line, the details of each system's track matter enormously. A second and less obvious pattern is Appalachian cold-air damming, in which high pressure to the north wedges a shallow layer of cold air against the eastern slopes; it can hold the region grey, raw and stubbornly cool for days while the barometer stays elevated, and it often decides whether a storm falls as ice or rain. Summers run humid under the Bermuda high, with atmospheric pressure today fairly flat and afternoon thunderstorms firing along the boundary between the Piedmont and the coastal plain. Late summer and early autumn bring the remnants of tropical systems curving up from the south, capable of a sustained drop and days of heavy rain. For weather-sensitive residents, a barometric pressure forecast for Silver Spring is worth following year-round, with the largest swings from November through March.
What this means for you
Can barometric pressure cause headaches? In the mid-Atlantic the coastal storm is the classic trigger, because a developing low offshore can pull barometric pressure down steadily over a day or more. Using this barometric pressure forecast with a migraine tracker app like Pressure Pal lets you watch that build rather than react to it. Track barometric pressure today and get alerts when atmospheric pressure today starts to move.
