...WIND ADVISORY IN EFFECT UNTIL 1 AM EDT SUNDAY...
...FREEZE WARNING REMAINS IN EFFECT FROM 3 AM TO 10 AM EDT
SUNDAY...

The National Weather Service in Jackson has issued a Wind
Advisory, which is in effect until 1 AM EDT Sunday. 

* A cold front will bring strong northwest wind gusts tonight. 
  This will help to bring in much colder air overnight. 

* Winds will gust 40 to 50 mph at times, but will subside
  overnight. Low temperatures Sunday morning will be in the lower
  30s in most locations, but middle to upper 20s may occur across
  the higher ridges near the Virginia border and in the most
  sheltered valleys.

* The wind may knock down tree branches, blow around loose
  objects, and making driving in high profile vehicles difficult.
  Freezing temperatures could damage or kill sensitive vegetation
  that is left unprotected. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Freeze Warning means sub-freezing temperatures are imminent or
highly likely. These conditions could kill sensitive vegetation.

A Wind Advisory means that wind gusts of at least 40 mph are 
expected. Winds this strong can make driving difficult... 
especially for high profile vehicles. Use extra caution.
