Winter Weather Advisory
Statement as of 2:54 am EST on November 20, 2008

... Winter Weather Advisory in effect from 6 PM this evening to
6 PM EST Friday...

The National Weather Service in Pittsburgh has issued a Winter
Weather Advisory for snow... which is in effect from 6 PM this
evening to 6 PM EST Friday.

Snow accumulation of up to 6 inches is possible from
Thursday evening through Friday as a cold northwest flow develops
across the lakes in the wake of a strong cold front.

A Winter Weather Advisory for snow means that periods of snow
will cause primarily travel difficulties. Be prepared for snow
covered roads and limited visibilities... and use caution while
driving.
