Airport corridor wind and valley ice in Windsor Locks
The town sits low along the Connecticut River with Bradley Airport's open ground on its west side, so there is little tree shelter and wind reaches roofs from the northwest with nothing in the way. Lifted tabs on the windward slopes are the usual result. Winter brings enough snow for ice to build at the eaves, and on the capes with cold attics that ice backs water under the first courses. River humidity keeps north slopes damp, so moss and lichen show up on shaded roofs. Spring runoff along the river and the canal adds to the wet season.
