DISCUSSION
 
 
A TROUGH SYSTEM WITH AN ASSOCIATED COLD FRONT WILL MOVE THROUGH THE  
REGION FROM THE NORTHWEST BRINGING ACCUMULATING SNOW, AN INCREASE IN  
THE WINDS, AND COLDER TEMPERATURES. EXPECT STEADY SNOWFALL AND A  
PICK UP IN WINDS AT INGNITION TIME AS THE FRONT WILL BE MOVING  
THROUGH FROM 0700-1300. TEMPERATURES WILL ALSO DECREASE AT THIS TIME  
WITH MAXIMUM TEMPERATURES REACHING ONLY IN THE MID 20'S WITH LOWS IN  
THE SINGLE DIGITS. AS A RESULT OF THE PASSING COLD FRONT,  
VENTILATION WILL BE VERY GOOD TODAY DUE TO THE INCREASING WINDS  
ENHANCING MIXING. WILL SEE A LITTLE BREAK THIS WEEKEND AS WE PREPARE  
FOR THE NEXT COLD SYSTEM EXPECTED TO MOVE THROUGH FOR MONDAY-TUESDAY.
