DISCUSSION
 
ANOTHER SUNNY, WARM, AND DRY DAY IS EXPECTED TODAY  
AS HIGH PRESSURE SLOWLY DEPARTS THE AREA. MIXING INTO DRIER AIR  
ALOFT WILL ONCE AGAIN DROP HUMIDITIES INTO THE MIDDLE 20 PERCENT  
RANGE ACROSS NORTHEAST WISCONSIN. FOR THE LAST FEW DAYS THE MOST  
NOTICABLE PERIOD OF LOWERING HUMIDITY OCCURRED BETWEEN 11 AM AND NOON.  
DUE TO THE VICINITY OF THE SURFACE HIGH PRESSURE RIDGE, WIND DIRECTION  
WITH ANY SUBTLE GUSTS TO 10 MPH MAY VARY DURING THE BURN PERIOD.  
 
SHOWERS AND THUNDERSTORMS WILL SPREAD ACROSS THE AREA TONIGHT,  
THEN CONTINUE AT TIMES THROUGH THE WEEKEND AS A SLOW MOVING
