I think it's possible, but not as common as the other, generally speaking. In some regions it's definitely used, I guess. Merriam-Webster lists those pronunciations too.
By the way, are you checking the pronunciation in American Heritage and related dictionaries? If so, be careful... American Heritage's audio clips don't sound very good to me, and I don't think they reflect a true modern American pronunciation. Merriam-Webster is the best and the most reliable by far for American English, in my opinion.
