Average retail gasoline prices in Omaha have dropped 4 cents a gallon in the past week, averaging $1.72 on Monday.
Nebraska's and Iowa's averages were down 5 cents for a gallon of regular unleaded from a week ago, to $1.75 and $1.74, respectively, according to AAA's fuelgaugereport.com.
The local numbers are lower than the national average, which has fallen 3 cents per gallon in the past week to $1.79. The national average was down from $2.05 a year ago.
The Omaha and Iowa averages Monday were down from $1.97 a gallon a year ago. Nebraska's average for a gallon of regular unleaded was down from $1.98 a year ago.
Regular unleaded was selling for as low as $1.49 a gallon at two locations Monday in Omaha and for $1.59 at several other stations.
Motorists, however, shouldn't become too attached to the recent low pump prices, a GasBuddy.com senior petroleum analyst said, because a rise could be on the horizon.
"Crude oil prices have rebounded back above $30 per barrel in the last two weeks, and with more talk of an organized cut in oil output between some of the world's largest producers, there may be more upside potential in the future,'' said Patrick DeHaan.
"For now, due to a lag time from rising oil prices, gasoline prices in many areas may continue to drift lower, but don't be caught by surprise if in a few weeks they revert and move higher,'' he said.
"Refiners have already begun some winter maintenance, and while supply of winter gasoline is abnormally high, once that inventory is liquidated, I fully expect gasoline prices to march higher."
According to GasBuddy.com, regular unleaded gas prices on Feb. 1 in Omaha have ranged widely over the past five years: $1.99 per gallon in 2015; $3.13 in 2014; $3.47 in 2013; $3.37 in 2012; and $3.14 in 2011.
