The National Weather Service has issued a freeze watch for our area beginning late Friday night through Saturday morning. Temperatures will fall below freezing by midnight, with the coldest temperatures expected before sunrise Saturday. Temperatures rise above freezing by around mid-morning Saturday. Freezing temperatures will damage or kill sensitive vegetation Friday night so you’ll need to take steps to protect tender plants from freeze conditions. Martinsville should see a low of 25 Friday night and 28 Saturday night.
