DISCUSSION
 
 
HIGH PRESSURE WILL SHIFT EAST TODAY AS A WARM FRONT APPROACHES  
FROM THE WEST. CLOUDS WILL OVERSPREAD THE AREA TODAY AND LOOK FOR  
SOUTH TO SOUTHEAST WINDS TO INCREASE AND BECOME QUITE STRONG IN  
THE RED RIVE VALLEY. EXPECT SMOKE DISPERSAL TO IMPROVE TO THE GOOD  
CATEGORY AS THE DAY PROGRESSES WITH WINDS INCREASING DUE TO  
INVERSION BREAK. THERE IS A SMALL CHANCE FOR A LITTLE LIGHT SNOW  
AND RAIN OVER MAINLY WEST CENTRAL MINNESOTA THIS AFTERNOON AS  
MOISTURE MOVES EAST AHEAD OF THE WARM FRONT. FOR NOW, LOOK FOR  
MINIMUM HUMIDITIES TO DECREASE TO AROUND 30 PERCENT AROUND MID  
AFTERNOON.  
 
TONIGHT WILL SEE THE GUSTY SOUTH TO SOUTHEAST WINDS CONTINUE.  
 
OTHERWISE, AN UPPER LEVEL SYSTEM TO OUR SOUTH WILL SPREAD  
MOISTURE AND AREAS OF LIGHT RAIN OVER THE AREA DURING THE DAY  
THURSDAY AND THURSDAY EVENING.
