.DISCUSSION...
A FRONTAL BOUNDARY WILL STAY DRAPED ACROSS OUR REGION FOR THE NEXT SEVERAL
DAYS. THIS WILL KEEP A CHANCE OF SHOWERS AND THUNDERSTORMS IN THE FORECAST 
INTO THE WEEKEND...WITH WETTING RAINFALL LIKELY EACH DAY. THE COMBINATION 
OF RELATIVELY LOW MIXING HEIGHTS AND LIGHT TRANSPORT WINDS WILL CREATE FAIR 
TO POOR VENTILATION AND DISPERSION THROUGH THE PERIOD. MINIMUM RELATIVE 
HUMIDITY VALUES WILL BE ABOVE 50 PERCENT FOR THE NEXT SEVERAL DAYS.
