In pursuit of the Meteors' score of 196 that was highlighted by opener Katie Mack's unbeaten century, Patterson remained in control of the chase to bring up her own hundred off 154 deliveries and help the Scorpions celebrate their first win of the WNCL season.
Patterson carried her bat to finish unbeaten on 108 from 162 in a perfectly controlled knock that featured eight fours and one six.
In a low-scoring game where 10 batters were dismissed for single-figure scores, Patterson and Mack were the standout performers.
With Scorpions opener Tahlia McGrath (9) and first drop Josie Dooley (6) unable to make an impact, it was young gun Courtney Webb who stood up to combine with Patterson to steer the visitors home.
Webb, playing in just her second match for the Scorpions after relocating from Tasmania, complemented Patterson's knock with a crucial 52 from 75 balls.
By the time Webb was dismissed in the 46th over, Jemma Barsby joined Patterson to easily add the 19 runs required for victory, the winning runs coming with eight balls remaining.
Earlier, Meteors opener Mack staged another impressive individual performance, also finishing unbeaten on 106 from 131 balls.
In the face of a fearsome opening spell from Scorpions spearheads Megan Schutt and Darcie Brown, Meteors opening pair Mack and Rebecca Carter settled early to put on a 65-run opening stand that wasn't broken until the 16th over when Samantha Betts trapped Carter on the pads for 26.
Carter was the first of three key strikes for Betts, who followed up with the wickets of Erin Osborne (7) and Angela Reakes (1) in quick succession.
But Mack continued to keep the scoreboard moving for the Meteors, driving, pulling and ramping confidently as well as running hard between the wickets, despite wickets falling around her.
The Scorpions will next play Queensland at Allan Border Field on Saturday, 20 February.
