River valley damp and ridge weather in Farmington
The Farmington River runs through town and keeps the low ground damp, so roofs in Unionville and along the river hold moss and dry slowly. The Talcott ridge to the east stalls storms and drops heavy snow on the slopes below it. Mature trees shade most neighborhoods, filling valleys and gutters every fall and dropping limbs in ice storms. Winter freeze and thaw is aggressive on the old houses with cold, uninsulated eaves and on the complex rooflines of the newer colonials, where ice finds every inside corner and dormer valley.
