Pressure and weather in Plainville
Plainville sits in a low basin in the Farmington valley, with the Metacomet traprock ridge rising sharply to the east and higher western hills beyond town. Those ridges are only a few hundred feet tall but they do real work, sheltering the valley from westerly wind and helping cold air pool on clear nights, so frost forms here earlier and lingers later than on the surrounding higher ground. Central Connecticut also sits inland enough to stay well on the snow side of most winter storms while still catching the full pressure signature of them. Coastal lows deepening off southern New England produce this area's biggest barometer swings, with a long fall through the approach and a sharp rise as the storm pulls away and northwest wind scours the valley. A local complication is the coastal front, a boundary that often sets up between the milder shoreline and the colder interior and can leave Plainville with sleet while Hartford has rain and the hills have snow. Summer is humid, with afternoon storms that intensify as they cross the valley. A barometric pressure forecast for Plainville is most valuable from December through March.
