Jones was introduced at the break and took just four minutes to find the net. After she netted again in the 66th minute, Llanfair did find a way through the Llandudno defence as Mary Bailey got her side on the scoresheet, but 19-year-old Jones completed her treble four minutes from time.
Airbus UK Broughton moved off the bottom of the table following their goalless draw with Rhyl 1879 at the Hollingsworth Group Stadium.
Storm Isha took its toll in Flintshire as neither side were able to find the back of the net in a tight affair. Both teams claim their second league clean sheet of the season, with Airbus picking up a point for the first time since October whereas Rhyl remain in fourth place.
