.DISCUSSION...

Hot and dry conditions continue until Wednesday afternoon, when the 
arrivial and passage of a cold front will trigger showers and some 
thunderstorms during the afternoon and evening hours. Relative 
humidity values will fall into the 20% to 30% range areawide today, 
and then 20% to 30% in the Piedmont, but 40% to 50% in parts of 
southeast WV and far southwest VA for Wednesday. After that, RH will 
remain high through the end of the week and into the weekend as 
moisture and precipitation chances linger. Forecast rainfall amounts

beneficial for the area, and may lead to some improvements in the 
ongoing dryness, and thus could reduce the overall fire weather 
threat across the area heading into the warmer months.
