Lowery, who tallied twice in the tournament opener on Friday, lit the scoreboard with a 10-yard boot eight minutes into Saturday's game and Grant Brown followed with another score four minutes later.
Lowery then put the finishing touches on things with two more scores in the final 20 minutes of the first half.
"It's a good start to the season," Lowery said. "It's probably the worst weather conditions I have ever experienced. It was tough out there and the passing was really affected."
While pleased with the five goals in the first two outings, Lowery was more impressed by his teams' efforts to date.
"The defense has really stepped up," Lowery said. "And we're doing some good things on offense."
Boonsboro coach Brad Delauter was also satisfied with the performance.
"It was tough playing conditions out there, but I thought we did a nice job," Delauter said. "With the lead, I was able to use some additional players in the second half and we got contributions from a number of players."
· With the rain finally subsiding, the playing conditions improved for game two but neither Williamsport nor North Hagerstown could make any serious scoring threats in the first 80 minutes of play.
Williamsport goalie Derek Munro and North counterpart Joel Henry denied every opportunity and the regulation game ended in a scoreless stalemate.
In the extra session, Williamsport got successful penalty kicks from Edwin Reyes, Michael Reyes, Bryan Whitmore and freshman Cody Gardenhour.
Only Allen Sandberg and Alex Rauch could counter for North.
"It was tough, but we got the job done," first-year Williamsport coach Chris Downs said. "Munro did a great job in goal and although we didn't score in regulation, we moved the ball a little better than Friday. It's going to take a few games to make the proper adjustments and get the right people positioned on offense. It's a learning curve."
North coach Glen Singer said, "The defensive effort was encouraging, but we need to find some scoring. It's early in the year. Hopefully, we'll improve."
