Gas Price Info With National Gas Temperature Map

Paid $0.00/gallon at Mobil on Thursday :)

When I got new tires for my car last month, even though I wasn't technically eligible, since my uncle used to work at that dealership, the Service Dept pushed through a $70 prepaid Mobil card and an $80 Visa debit rebate card. Both came in the mail last week. I managed to squeeze $65 worth of gas at $2.49/gallon, so I have $5 to burn up still on that card.
 
Seeing gas at $1.99 in some places here now but seen some gas stations jump prices back up to $2.39 wow what a jump, ouch. What is going on now to cause this jump again?
 
I have been getting only 5 gallons at a time as prices continue to fall, now may be the time to fill up if prices have stabilized/start rising again. Can still get 1.99 here (1.95 if I drive farther, but not worth it)
