St. Louis (KSDK) - While gas is in short supply on the East Coast, demand for gasoline is down due to fewer drivers on the road after Superstorm Sandy, and analysts predict Sandy will push prices lower.

That appeared to be the case locally when gas dropped to $2.99 per gallon this week.

Then on Thursday the price shot up 20 cents in some places. Whenever that happens drivers wonder why.

As recently as September we were paying more than $3.70 per gallon, so it was welcome relief this week when gas prices dropped below $3 dollars, unless you didn't realize there had been a price drop.
