DISCUSSION
 
A WEAK REINFORCING SYSTEM PUSHES SOUTHWARD THROUGH  
THE DAY MONDAY, RESULTING IN A CHANCE OF SCATTERED SNOW SHOWERS  
AND MOSTLY CLOUDY TO OVERCAST SKIES. NORTHWEST WINDS EXPECTED TO  
INCREASE INTO THE AFTERNOON, WITH MAGNITUDES GENERALLY AROUND 15  
TO 20 MPH, WITH GUSTS TO AROUND 25 TO 30 MPH POSSIBLE. WITH THE  
ELEVATED WINDS/TRANSPORT WINDS AND MIXING HEIGHTS INCREASING TO  
AROUND 2700-3500 FT AGL, EXPECT MORNING CLEARING INDICES OF  
AROUND 500 TO INCREASE TO ABOVE 700 DURING THE AFTERNOON.  
 
SYSTEM DEPARTS REGION LATE EVENING INTO THE OVERNIGHT HOURS, AND  
SNOW CHANCES DIMINISH WITH SKIES GRADUALLY CLEARING.  
BY TUESDAY MORNING, WINDS ARE EXPECTED TO BE MORE NORTHERLY  
AND LIGHTER AROUND 5 TO 10 MPH, AND REMAIN AROUND THAT THROUGH  
THE DAY. COMBINATION OF HIGHER PRESSURE AND ASSOCIATED LOWER
