IN PRINT TODAY, MAY 7, 2010 - John Polyniak, in Lake Shore, says he thinks local TV and the Weather Channel regularly report temperatures for Laurel that are a few degrees cooler than the suburbs north and west of Baltimore: “What is the reason for this?” Hard to say without knowing where the sensors are. In summer, the bay breeze may benefit Laurel more than, say, Towson. More likely, it’s the cooling effects of greenery at the Patuxent Wildlife Refuge and USDA Agricultural Research Station.
