FIRE WEATHER PLANNING FORECAST FOR CENTRAL SOUTH CAROLINA  
AND EAST CENTRAL GEORGIA  
NATIONAL WEATHER SERVICE COLUMBIA SC  
250 PM EDT MON OCT 23 2017  
   
DISCUSSION
 
A COLD FRONT CURRENTLY EXTENDING FROM EXTREME  
WESTERN NC DOWN THROUGH SOUTH-CENTRAL GA WILL MOVE SLOWLY EAST  
ACROSS THE FORECAST AREA LATE THIS AFTERNOON THROUGH MID-EVENING.  
AHEAD OF IT, WINDS FROM THE SOUTH-SOUTHEAST COULD BECOME QUITE  
GUSTY IN SCATTERED SHOWERS AND THUNDERSTORMS, WITH THE POTENTIAL  
FOR ISOLATED TORNADOES.  
 
WINDS WILL THEN SHIFT OUT OF THE WEST-SOUTHWEST BEHIND THE FRONT  
AND DIMINISH TO AROUND 5 MPH INTO THE OVERNIGHT HOURS.  
FAIR DISPERSION IS EXPECTED THROUGH MUCH OF THE EVENING AND  
NIGHTTIME. ANY FOG LATE TONIGHT IS EXPECTED TO BE VERY PATCHY  
WITH DRIER AIR BEGINNING TO FILTER IN AND SOME WEAK LOW-LEVEL  
MIXING OCCURRING.  
 
SURFACE WINDS TUESDAY WILL BE FROM THE WEST-SOUTHWEST AROUND  
5 MPH AFTER DAYBREAK, THEN INCREASE TO 8 TO 12 MPH BY LATE  
MORNING. TRANSPORT WINDS WILL ALSO BE WEST-SOUTHWEST INCREASING  
TO 14 TO 18 MPH FOR THE AFTERNOON. RELATIVE HUMIDITIES WILL  
DROP TO NEAR 40 PERCENT.
