WASHINGTON -- A fast-moving band of snow showers is expected to move through the region early Friday morning, bringing anywhere from a dusting to an inch of snow during the rush hour commute.  The National Weather Service has issued a Winter Weather Advisory through 10 am.

While the storm could cause some school delays, it is not expected to have the same impact on schedules as previous small storms this season.  The Federal Office Of Personnel Management, for example, is planning to open on time today for all employees.
