Pressure and weather in Missouri City
Missouri City lies at about 60 feet on the coastal prairie between Oyster Creek and the Brazos, roughly fifty miles inland from Galveston Bay with essentially no terrain in any direction. That flatness means the barometer here is a pure record of synoptic weather systems, with none of the valley pooling or orographic complications that muddy readings elsewhere. The dominant event is the Gulf hurricane season, from June through November and concentrated in late August and September. A landfalling or nearby tropical system produces the deepest and fastest pressure fall the region ever sees, and because upper Texas Gulf storms often slow down or stall after landfall, the minimum can be broad and the rainfall extraordinary rather than the wind being the main story. The other half of the year belongs to continental cold fronts. From October through March, fronts sweep south off the Great Plains and cross the coastal plain as sharp wind shifts, dropping the dew point twenty degrees within an hour and sending the barometer climbing steadily behind. Between fronts, the Gulf reasserts itself with humid onshore flow and a flat reading. High summer is the quietest barometric stretch, dominated by heat and daily sea-breeze thunderstorms that barely register.
