Panthers halfback Jamie Soward was the standout, having a hand in all four of Penrith's tries. But it was his pass for Moylan's last-gasp field goal that was the difference on a soaking night in Penrith.
The win consolidated Penrith's spot in the top four, jumping over the Roosters into third spot, while the Cowboys remain in seventh spot on 26 points.
From the moment Josh Mansour fluffed a Robert Lui bomb in the first minute that led to a Kane Linnett try two minutes later, the question was immediately asked: 'How much of a lead was this stiff southerly worth?'
But the Panthers took the blistery conditions out of the equation with three consecutive tries in the 11th, 27th and 33rd minutes to put themselves in a strong position.
The first was straight out of the Roger Tuivasa-Sheck playbook, with a drifting Soward dropping Penrith's own whizkid in Dallin Watene-Zelezniak on the inside and then producing a wicked left foot step that opened up a path for Soward to go over in the corner.
The breeze was so strong that Soward's sideline attempt barely went the distance.
But after potting over a penalty in the 18th, the reborn Panther ignored another gift two points from in front and stepped his way past a couple of defenders for his second try nine minutes later.
Content with a first-half double, Soward then conjured a towering bomb for Jamal Idris, who batted it back for Jeremy Latimore to slam the ball over, leaving the visitors wondering whether they had taken the right decision after winning the toss.
Fortunately the Cowboys, who copped five of the first six penalties of the match, earned back-to-back penalties themselves and used it to great effect when Gavin Cooper's show-and-go put Glenn Hall over to reduce the margin to four points at the break.
In an exact replica of the first half, the hosts opened the second with an error and the Cowboys made them pay immediately, stealing the lead through Lui's twisting effort in the 43rd.
More errors and ill-discipline had the home team camped on their own line for the next few sets but the game changed when Soward's 70m intercept ended with Cowboys centre Matthew Wright being sent to the sin bin.
And the former Dragon followed it up with his second try assist of the night, throwing a remarkable 20m cut-out pass for Mansour to regain the lead for his side.
From there the game slowed into a grind before it was again turned in its head in the 68th minute, when Segeyaro limped off at the same time Winterstein set up the grandstand finish with a 30m try off a Lui bomb that was allowed to bounce in the backfield.
Penrith 23 (Soward 2, Latimore, Mansour tries; Moylan 2, Soward goals, Moylan field goal) defeated North Queensland 22 (Linnett, Hall, Lui, Winterstein tries; Thurston 3 goals). Crowd: 7,276.
