Triple Hs of summer on hold…so far… July 6, 2009

The typical hazy, hot, humid days of summer have been put on hold by a cooler than normal weather pattern.  Low pressure in eastern Canada continues to funnel cooler and drier than normal air into the mid Atlantic and northeastern United States.  At BWI-Marshall, we have not hit 90° since an unusual three day heatwave [...]
