Pennsbury, which is ranked No. 7 in Southeastern Pennsylvania by The Inquirer, improved to 2-1; No. 8 Downingtown East dropped to 2-1.
Registering three touchdowns for the second consecutive game, Snorweah, a 5-foot-10, 170-pound junior speedster, scored on runs of 27, 6, and 15 yards.
With a little more than eight minutes to go, Smith surged through the middle, dashed toward the left sideline, and went 22 yards for a score that put the Falcons in front, 26-14.
In holding Downingtown East to a pair of scores, Pennsbury's 4-4 defense was led by junior lineman Jordan O'Neill, senior linebackers John Jakimowicz and Quinn Pfender, and senior safety Brendan Campbell.
In the third quarter, after Snorweah's 15-yard touchdown run gave the Falcons a 20-7 advantage, Campbell intercepted a pass by Downingtown East quarterback Ryan Rumer at the Pennsbury 8.
Snorweah's 27-yard, left-side run late in the first quarter gave the hosts an early lead. Downingtown East, which opened the season with wins over Frankford and Roman Catholic, answered with Ryley Angeline's 2-yard plunge.
With less than three minutes to go until intermission, after Clark hit Snorweah on a 46-yard pass, Snorweah found pay dirt from the 6 to make it 14-7.
Late in the third frame, Angeline's 7-yard touchdown rumble cut the gap to 20-14. Pennsbury responded with a seven-play, 71-yard scoring series. It included a 20-yard run by Smith and an 18-yard scamper by Clark.
In the late going, Pfender's interception at the Downingtown East 26 clinched a lightning-delayed triumph.
