DISCUSSION
 
 
AN ARCTIC WEATHER FRONT PUSHING SOUTH ACROSS THE NORTH SLOPE  
INTO THE YUKON FLATS WILL FACILITATE INCREASING WINDS ALONG WITH  
THE CHANCE FOR PRECIP TONIGHT INTO TOMORROW. THE INFLUX OF  
MOISTURE FROM THE WEST WILL HELP INCREASE RELATIVE HUMIDITY FOR  
MOST OF THE FORECAST AREA. A SMALL EXCEPTION WILL BE THE UPPER  
TANANA VALLEY EAST OF DOT LAKE TO THE FORTYMILE COUNTRY WHERE  
RELATIVE HUMIDITY WILL REMAIN IN THE HIGH 20S TO LOW 30S.  
SOUTHWEST WINDS WILL PICK UP ACROSS THE YUKON FLATS TO 15-20 MPH  
BEGINNING THIS EVENING AND INCREASE THROUGH THURSDAY AS THE FRONT  
DROPS SOUTH BEFORE STALLING OVER THE CENTRAL INTERIOR UNTIL  
FRIDAY. AREAS SOUTH OF THE FRONT WILL REMAIN DRY, THOUGH WEAK  
WINDS AND MARGINALLY WARM TEMPERATURES SHOULD NEGATE THE FIRE  
THREAT.
