What’s the “future” for price at the pump?

Lately, futures prices for crude oil and refined products such as gasoline and heating oil have been in a free-fall.  For example, the January 2015 futures contract for “RBOB Gasoline” is trading at the equivalent of around $1.64 per gallon.  As shown in the following graph, this represents a price drop of roughly 85-90 cents per gallon since September:

AAA reports that today’s national average is $2.639 and could fall to $2.50 within the next couple of weeks.  Nationally, the average markup from the near term futures contract price to prices at the pump has averaged 62 cents per gallon since January 2000 (which is when AAA began tracking this information).  Therefore, if futures prices hold at (or fall further from) current levels it seems quite likely that the price at the pump may be headed even lower.
