Doesn't appear to be a problem in the Memphis area although it does seem like there are more people at the pump than usual but no lines so far. Prices are holding steady at about $3.65 for regular.
Nashville had the same problem about 2 weeks ago with there being no gas in the city -- we drove around for like 30 min looking and then gave up one day. The next day I waited an HOUR to get gas. But normal supply and demand has resumed over the last week and a half. Gas has even gone down to about $3.35 a gallon.
I heard in Cleveland they're paying $2.79 for regular unleaded -- lucky people!
