The National Weather Service will be in Kent and Sharon today to determine whether a tornado touched down yesterday afternoon.  They're inspecting damage along Route 7 in Kent.  A section of the road near Kent Falls State Park was blocked by downed trees.  A house fire in Newtown may have been caused by a lightning strike yesterday.  All of the town's volunteer fire companies responded to the Sandy Hook section to but out the blaze.  Brookfield firefighters also responded to the scene, along with a tanker truck from Stevenson Volunteer Fire Company. The Newtown Fire Marshal's office is investigating the exact cause.
