River-valley weather on Glastonbury's slopes
The town rises from the Connecticut River to Minnechaug Mountain, so exposure changes with elevation. The river flats hold fog and frost; the hillside subdivisions take wind and heavier snow. Big colonials with many intersecting slopes collect snow in their valleys and build ice in the inside corners and behind dormers. Tree cover is heavy in East Glastonbury and along the older roads, so moss, debris and limb damage are routine, while the orchard country of South Glastonbury is open to wind off the river. Summer storms track up the valley with gusts.
