Mary Frances Wagley of Cockeysville says it seems the daily high and low temperatures are "rarely" more than 10 degrees apart, while the historical spread is more than 20 degrees. "Is there a known cause for this change?" she asks. The daily high/low spread at BWI has averaged closer to 18 degrees this month. But Robert Henson of the National Center for Atmospheric Research says urban "heat-island" effects, warming air and oceans, and rising humidity have been brakes on nighttime cooling globally.
