Happy Friday. Before taking off for the weekend, take a quick look at five stories to know about:
1. Late start for Philly schools?: Philadelphia School District Superintendent William Hite says the start of the school year will be delayed unless the district gets assurance by Aug. 16 that it will receive $50 million from the city. Schools in the cash-strapped district are slated to open Sept. 9. Mayor Nutter called the superintendent's announcement "one of the most chilling statements that I've ever heard a school leader ... make." After massive layoffs this summer due to the district's massive budget defecit, Hite contends that the schools won't be fit to operate unless they receive the extra funds.
2. N.J. Powerball winners: Reports surfaced late Thursday that 16 workers from the Ocean County Vehicle Maintenance Department have one of the three winning tickets in the $448 million Powerball jackpot. The winning employees showed up for work Thursday, the department's director says. They bought their ticket at an Acme Markets store in Little Egg Harbor. Another winning ticket was also sold in New Jersey, but no one has come forward to claim it. A Minnesota man claimed his share of the prize -- one of the largest jackpots in lottery history -- on Thursday.
3. Eagles preseason games begin: The Eagles face off against the New England Patriots tonight at Lincoln Financial Field in the team's first preseason game. Michael Vick will start at quarterback tonight, but he will alternate first-quarter snaps with Nick Foles (who is slated to start in next week's game against the Carolina Panthers). Game time is 7:30 p.m.
4. A.C. casino revenue: Revenue figures are due out this afternoon for Atlantic City's casinos. July is typically one of the busiest months of the year, and today's numbers will show how the 12 casinos fared. For the first six months of the year, revenue was down nearly 11 percent from the same time in 2012.
5. Dolphin deaths study: Federal officials will lead a study into the unusually high number of dead dolphins that have washed ashore in New Jersey this summer. The National Oceanic and Atmospheric Administration has declared the 91 dead or dying animals found between New York and Virginia -- with 20 in New Jersey -- an "unusual mortality event."
