Pressure and weather in Meadowbrook
Meadowbrook lies at about 150 feet between the James River and Falling Creek, on the inner edge of the Virginia coastal plain where the hard rock of the Piedmont gives way to sand and clay. Its barometer answers to three separate weather regimes. In autumn, tropical systems that come ashore in the Carolinas or ride up the coast deliver the deepest single falls of the year, and because Richmond sits well inland these usually arrive as weakening but still substantial lows with heavy rain and a broad pressure minimum lasting most of a day. In winter the action moves offshore: coastal lows developing near Cape Hatteras can either miss to the east or track close enough to bury the area, and the same storm may produce a fifteen hPa fall with nothing but rain, or with six inches of snow, depending on fifty miles of track. Layered on top of that is cold-air damming, the pattern in which dense cold air spills down from the north and wedges against the eastern slope of the Blue Ridge. During a damming event the reading stays stubbornly high while freezing rain falls, which is the local way a quiet barometer accompanies genuinely bad weather. Summer is the dull season, with heat, humidity and afternoon thunderstorms that stir the reading only briefly.
