Gas Price Info With National Gas Temperature Map

Out of an abundance of caution, I topped off (10.6 gallons) on my last Costco run and I'm glad I did as the price moved up six cents/gallon to $3.159 after being steady at $3.099 for three weeks. It is only 61 cents but it is the principle.
 
My Costco regular pricing stayed the same ($3.159) but the premium pricing now has a 44-cent differential where it is normally 40 cents more.
