New South Wales 302 for 4 (Salzmann 73, Philippe 69*) lead Tasmania 136 by 166 runs
Only 42 overs were possible in the day-night game at Ninja Stadium on Tuesday, with NSW adding 164 for the loss of two wickets.
Philippe, who recently played two T20I games for Australia in Pakistan, has struggled for runs domestically this season. He had scored just two fifties across the three domestic competitions with NSW and the Sydney Sixers, but finished Tuesday unbeaten on 69.
Hot and blustery conditions gave way to rain just before 6pm local time and no further play was possible.
Philippe’s highlights included smashing sixes off successive balls from spinner Nikhil Chaudhary.
Edwards punished the quicks, pounding leg-side sixes off both Jackson Bird and Riley Meredith.
Tasmania competed well In the first session, quickly dismissing NSW captain Kurtis Patterson and making life tough for youngster Lachlan Shaw.
Prolific Patterson added just four to his overnight score of 29 before he was adjudged lbw to a Gabe Bell delivery.
Shaw, who scored just one off 22 balls on Monday, took 19 more deliveries to notch his first run on day two.
He became progressively more confident, tallying five fours in his 38 and putting on 90 with Philippe, before being bowled by Tasmania captain Beau Webster.
