Muralists Herb Roe, from front, Gregg Gowland and Benny Graeff wash a wall on Grove Street just east of Levee Street as they prepare it for a Run Thru History mural that will be painted on the spot just across the street from the 32 historical Riverfront Murals. The artists were working during the only rain Vicksburg has seen in a month. They said the quick downpour, however, was a help rather than a hindrance in their prep work for the mural they expect to have completed in about three weeks. “It’s the only thing out here we do that the rain would help,” said Roe. Tuesday’s rain is forecast to be followed by a week of sunny skies and cooler temperatures.
