Bob Hoffman uses a Bobcat frontloader to dig out piles of snow Tuesday in the lot at Rick Bockman Inc. on East State Street as the Olean area enjoyed temperatures well into the 40s — a welcome respite from the arctic air that prevailed for several days. The high Wednesday was only expected to reach into the upper 20s and some snowfall was likely. While highs the remainder of the week should be in the 20s, the weekend could be warmer, with highs in the mid- to upper 30s, according to the U.S. Weather Service in Buffalo.
