As many motorists are preparing for the Memorial Day weekend of travel, they will find that gas prices in Wyoming, are right about where they were this time last year. Senior Petroleum analyist Patrick Dehaan says in past years, prices normally climb around the holiday weekend...but now-a-days, the price hike has been starting around February and March.

"What we're seeing this year is that the increases have slowed down now, and by June we should start to see prices actually going back down. That's just because refineries do maintenance starting in that February/March time slot, and that maintenance usually wraps up by Memorial Day, and that helps put downward pressure on gas prices."

Dehaan says summer gas prices are usually more volatile in August and September, compared to June and July, because of the Atlantic hurricane season.

Gas is selling for as low as $3.34 cents per gallon in Gillette, $3.35 in Cheyenne and Laramie and $3.36 in Casper.

The state average is $3.46 and the highest known price in Wyoming, is $3.78 in Pinedale.

The national average is $3.63.
