.DISCUSSION...
LOW PRESSURE WILL MOVE FROM THE OHIO VALLEY TO THE MID ATLANTIC REGION...
DRAGGING THE FRONTAL BOUNDARY THAT PUSHED SOUTH OF OUR AREA YESTERDAY 
BACK NORTHWARD AS A WARM FRONT. THIS WILL BRING SHOWERS AND THUNDERSTORMS
TO THE REGION WITH A WIDESPREAD WETTING RAIN EXPECTED. OUR WEATHER WILL 
REMAIN UNSETTLED...WITH A SERIES OF UPPER LEVEL DISTURBANCES BRINGING A 
CHANCE FOR SHOWERS AND THUNDERSTORMS THE REGION THROUGHOUT THE WEEKEND...
WITH WETTING RAINFALL 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.
