Sunday’s weather forecast is for sunny skies and temperatures in the low 80’s. That’s perfect for Greg Westhoff’s Westchester Swing Band to set up outdoors on Division Street in front of Ruben’s Mexican Cafe for a concert from 5:30 until 8 p.m. The music is free and open to the public. Westhoff last performed in Peekskill in June and plans on having at least 18 pieces on Sunday, depending on if there are four or five trumpets, four or five trombones.
