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

threat across the area heading into the warmer months.
