"The national average has seen its bounce continue in the last week across most of the nation," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "Some of the lows we saw just a couple weeks ago have vanished, replaced by higher digits as oil prices rallied. It will be an interesting week ahead as some notable progress emerged after developed countries came to a partial solution on Iran's nuclear ambitions. Just that action alone may result in significant downward pressure on oil prices as tough sanctions may soon be eased, allowing Iran's oil to flood an already well-supplied marketplace," DeHaan said.
