I don’t want to give too much credence to this theory but I’ll say this. I lived in southern Maryland for 6-7 years between 2003 and 2009. I lived in Tall Timber’s, Lexington Park, St. Mary’s City, Ridge and Park Hall. Southern Maryland is muuuch warmer than the DC area in the Spring, Summer, Fall and Winter. The climo is terrible and humid and warm. Late fall is often warm and humid and storms that are a cold 4-6 inches in downtown dc are a touch of sleet to rain. We should prob try to be more aware of our climo and the fact that the climo in Martinsburg is drastically different than St. Mary’s City.
