The Lehigh Valley Discourse show is hosted by Sally Handlon.
"It's going to be a fast-paced, fun show," said McGran. "Bill provides an amazing wealth of weather knowledge – he can predict what to expect a year from now.
"Long-range weather forecasting is what he does for a slew of national companies, including Walmart and Anheuser-Busch."
McGran will discuss business trends around the nation and here in the Lehigh Valley.
The program runs from 6-7 p.m. on dial positions WDIY 88.1, 93.7 FM West and 93.9 FM East.
