Firstly, we're talking about gas prices, not actual oil prices. As such, the real question is the impact of the storm on refineries. The actual impact is expected to be neglible - add to that reduced demand for gas because people are not travelling for days at a time, and the fact that prices were low going into the weekend, and we will not see any sustained increase in prices.
Secondly, you obviously ignored me saying "Or it'll be due to effects of volatility in the commodities market" nevermind that I never said there would not be any kind of increase. Even in this event, any effect should be short lived, and the downward trend it's been on should continue, barring any unforseen circumstances.
Which is more or less what you just stated.
